Morphofunctional evaluation of peripapillary retinoschisis associated with myopic posterior staphyloma and hyaloid traction: does it cause peripapillary vitreoretinal traction? / Avaliação morfofuncional da retinosquise peripapilar associada ao estafloma posterior miópico e à tração hialoidea: isso causa tração vitreo-retiniana peripapilar?

ABSTRACT This case report presents the details of a 33-year-old female patient who was referred to a specialized retina service because of mild vision loss in her right eye). The patient's visual acuity was 20/25 in right eye and 20/50 in the left eye (; amblyopic); the spherical equivalent was -12.75 diopters (right eye) and -14.75 diopters (left eye). Multimodal retinal imaging showed peripapillary schisis in both the inner and outer retinal layers, grade II posterior vitreous detachment, and a tessellated fundus. Using Humphrey perimetry and MP-3 microperimetry, the functional evaluation indicated macular sensitivity within normal limits and decreased sensitivity in the peripapillary region, especially in right eye. The pattern-re versal visual evoked potential was measured. The N75 and P100 latency and amplitude in right eye were within normal values for checks of 1º. However, the amplitude was low for checks of 15′. Highly myopic patients who have posterior staphyloma that involves the optic nerve are susceptible to posterior hyaloid traction, and the resulting peripapillary vitreous traction may compromise vision.

RESUMO Este relato de caso apresenta um paciente feminino de 33 anos encaminhado para um serviço especializado de retina devido à leve perda de visão em olho direito. A acuidade visual foi de 20/25 no olho direito e 20/50 no olho esquerdo, o equivalente esférico foi de -12,75 dioptrias e -14,75 dioptrias, respectivamente. Avaliações multimodais revelaram isquese peripapilar nas camadas internas e externas da retina, descolamento vítreo posterior grau II e fundo tesselado. Avaliação funcional com perimetria Humphrey e microperimetria MP-3 revelaram sensibilidade macular normais e diminuição da sensibilidade na região peripapilar, especialmente no olho direito. Potencial visual evocado de padrão reverso apresentou no olho direito latência e amplitude N75 e P100 dentro dos valores normais para verificação de 1º. Entretanto, a amplitude foi baixa para a de 15′. Pacientes alto míopes com esfiloma posterior envolvendo o nervo óptico são suscetíveis à tração da hialoide posterior. Portanto a tração vitreopapilar resultante pode causar comprometimento da visão.

Clinical study of rhegmatogenous retinal detachment treatment with minimally invasive foldable capsular buckle scleral buckling / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To investigate the clinical efficacy of minimally invasive foldable capsular buckle(FCB)scleral buckling in treating rhegmatogenous retinal detachment(RRD).METHOD: This retrospective study enrolled 11 patients(11 eyes)with RRD treated with minimally invasive FCB scleral buckling at the Hainan Traditional Chinese Medicine Hospital from May to July 2023. The surgeries were performed without subconjunctival anesthesia, extraocular muscle pulling, intraocular positioning, retinal cryotherapy or drainage of subretinal fluid, or FCB suture fixation. Furthermore, the best corrected visual acuity(BCVA), intraocular pressure and complications were observed.RESULTS: Minimally invasive FCB scleral buckling was performed on 11 eyes, with successful retinal reattachment in 10 eyes(91%), and the remaining 1 eye(9%)had postoperative retinal re-detachment and underwent vitrectomy with silicone oil filling for multiple retinal tears. One-time successful surgery was in 4 eyes(40%), gas injection in vitreous body after the surgery was performed in 1 eye(10%), FCB position adjustment after the surgery was performed in 3 eyes(30%), gas injection in vitreous body and FCB position adjustment after the surgery were performed in 2 eyes(20%); and FCB was removed 4-12 wk after the surgery in 5 eyes(50%), without retinal redetachment. The average BCVA(LogMAR)of the 10 eyes improved from 1.30±1.10 before surgery to 0.37±0.39 at 4 wk after surgery(P<0.01); the average preoperative intraocular pressure was 11.51±3.37 mmHg and 13.72±2.57 mmHg at 4wk after surgery(P>0.05). No serious complications occurred.CONCLUSION:Minimally invasive FCB scleral buckling effectively treats RRD with minimal injury, simple operation, time-saving, and fewer complications.

Modified silicone oil removal combined with scleral buckling for retinal detachment after silicone oil tamponade / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the efficacy of modified silicone oil removal combined with scleral buckling in the treatment of patients with retinal detachment under silicone oil tamponade.METHODS:The retrospective study included a total of 14 patients(14 eyes)who underwent treatment for retinal detachment with silicone oil tamponade at our hospital between January 2021 and February 2023. The modified silicon oil extraction combined with scleral buckling procedure was employed. A self-made 23-gauge suction device was applied in the silicon oil extraction, which involved removing the needle from a disposable blood transfusion set, trimming it to 2.5-3.0 mm near the beveled end, and connecting the other end to a 10 mL syringe without the plunger. The opposite end of the syringe was connected to the negative pressure system of the vitreous cutter to accomplish the silicon oil removal. Scleral compression blocks in scleral buckling surgery using a homemade composite device. No additional silicon oil was injected after the procedure. Follow-up was conducted for 6 mo, assessing retinal reattachment, best-corrected visual acuity(BCVA), intraocular pressure, and complications.RESULTS: At the 6 mo follow-up, the retina was completely reset in 13 eyes, with a retinal reset rate of 93%, and an improvement in BCVA(LogMAR)compared with the preoperative period(0.95±0.18 vs 1.15±0.21, P=0.002). Transient high IOP occurred in 6 eyes at 1 d postoperatively and returned to normal after medication control. There were no intraoperative complications such as retinal hemorrhage, retinal incarceration, or iatrogenic retinal breaks, and no postoperative complications such as endophthalmitis or choroidal detachment.CONCLUSIONS:Modified silicone oil removal combined with scleral buckling can effectively treat retinal detachment in the silicone oil tamponade and induce retinal reattachment.

Comparison of intraoperative balanced salt solution injection or postoperative air filling for superior bullous retinal detachment / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To observe the outcome of intravitreal balanced salt solution(BSS)injection to increase intraocular pressure(IOP)after extrascleral subretinal fluid drainage, then scleral buckling(SB)to treat superior bullous retinal detachment(SBRD), and compare it with the effect of conventional surgery(without any intravitreal filling)and postoperative air filling.METHODS: Retrospective case-control study. A total of 72 patients(73 eyes)who underwent SB for SBRD from January 2018 to December 2022 in ophthalmology department of Xijing Hospital were included. The extrascleral subretinal fluid drainage was performed in all eyes. According to whether intravitreal injection was performed and different injections, patients were divided into three groups: with 24 cases(24 eyes)in the conventional group(no intravitreal injection), 23 cases(23 eyes)in the air group(sterile air was injected after surgery), and 25 cases(26 eyes)in the BSS group(BSS was injected during extrascleral subretinal fluid drainage). All patients were followed up until subretinal fluid was absorbed completely. The average surgery time, postoperative IOP, retinal reattachment rate, subretinal fluid absorption, visual acuity(LogMAR)and major complications were compared.RESULTS: All surgeries were completed successfully. The average surgery time of the conventional group, air group and BSS group were 63.17±13.22, 61.65±15.55 and 57.30±11.70 min, respectively. There had no significant difference among these groups(F=0.825, P=0.443). On the first post-operative day, the average IOP of the conventional group, air group and BSS group were 13.69±2.69, 16.40±2.86 and 18.35±2.88 mmHg, respectively. The average IOP of the air group and the BSS group were significant higher than that of the conventional group(F=17.18, P<0.001). Primary reattachment rates were 88%, 96%, and 100%, respectively. The postoperative BCVA was 0.71±0.42, 0.59±0.44, and 0.91±0.50, respectively, which were significantly higher than those before operation(all P<0.05), but there was no significant difference among groups(F=3.046, P>0.05). The main complications included subretinal hemorrhage in 1 eye from the conventional group and 1 eye from the air group, and a new retinal tear in 1 eye from the air group, resulting in localized retinal detachment.CONCLUSIONS: For SBRD patients with hypotony during SB surgery, intravitreal injection of BSS to properly increase the IOP and then complete the surgery can improve the reattachment rate and reduce postoperative complications. This method is safe and effective for selected SBRD patients.

Efficacy of C3F8 versus silicone oil tamponade in highly myopic macular hole retinal detachment / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To compare the outcome of C3F8 versus silicone oil tamponade after pars plana vitrectomy(PPV)and inverted internal limiting membrane(ILM)for the treatment of highly myopic macular hole retinal detachment(MHRD).METHODS: Retrospective clinical study. Totally 45 patients(45 eyes)with highly myopic MHRD who visited our hospital between January 2019 and August 2022 were selected as the research subjects. The patients were divided into two groups according to different intraocular tamponade agents: C3F8(22 eyes)and silicone oil(23 eyes)groups. All patients underwent conventional three-incision PPV, ILM was tamped, a venous blood clot was placed on the tamped ILM, and 15% C3F8 and silicone oil were used as tamponade, respectively. The best corrected visual acuity(BCVA), multifocal electroretinogram(mfERG), the closure of the macular hole, retinal reattachment and the complications were observed.RESULTS: The macular hole closure rate was 77% in the C3F8 group and 83% in the silicone oil group, respectively(P>0.05), and retinal reattachment rates were 95% and 96%, respectively(P>0.05). The visual acuity of the two groups significantly improved, which was 0.99±0.34 and 1.22±0.37, respectively, and the C3F8 group was better than that of the silicone oil group(t=-2.156, P=0.037). After operation, the response density of the first ring of P1 wave in the first order kernel in mfERG was 114.27±26.37 nV/deg2 for the C3F8 group and 98.08±24.36 nV/deg2 for the silicone oil group, and the response density of the second ring of P1 wave was 80.45±14.94 nV/deg2 for the C3F8 group and 67.73±15.33 nV/deg2 for the silicone oil group, all of which were significantly higher compared to pre-operation [the response density of the first ring of P1 wave: 58.13±13.96 nV/deg2 for the C3F8 group and 55.30±10.48 nV/deg2 for the silicone oil group, the response density of the second ring of P1 wave: 51.18±8.19 nV/deg2 for the C3F8 group and 47.43±11.97 nV/deg2 for the silicone oil group](all P<0.05). It was found that the response density of the first ring of P1 wave was lower in the silicone oil group than in the C3F8 group(P<0.05). There was no statistically significant difference in the incidence of complications between the two groups(P>0.05).CONCLUSION: Silicone oil tamponade or C3F8 tamponade after PPV combined with ILM can both promote retinal reattachment and macular hole closure in patients with MHRD, and the C3F8 tamponade was superior to silicone oil in visual function recovery.

Alternativas de tratamiento de la obstrucción venosa retiniana: terapias combinadas y vitrectomía pars plana

Dentro de las enfermedades vasculares de la retina, la oclusión venosa retiniana es relativamente frecuente y debido a sus complicaciones afecta de forma moderada o grave la visión. Las opciones terapéuticas aplicadas en el edema macular y los desprendimientos de retina traccionales causados por las oclusiones venosas son varias. Se realizó una revisión en la literatura científica para valorar la eficacia y seguridad del uso combinado de diferentes terapias que incluye los antiangiogénicos y esteroides intravítreos con o sin aplicación de láser, así como la vitrectomía pars plana como alternativas de tratamiento de las complicaciones de la enfermedad oclusiva venosa retiniana. Aun cuando los antiangiogénicos se consideren como primera línea de tratamiento en la oclusión venosa retiniana, en varios casos hay mejor respuesta en sus combinaciones y de los esteroides con láser. Para resolver el desprendimiento de retina traccional y hemorragia vítrea, debidas a las oclusiones venosas, se requiere, mayormente, operación de vitrectomía pars plana. Se realizó una búsqueda en bases de datos electrónicas como PubMed, Cochrane y otras publicaciones relacionadas con las alternativas de tratamiento de la obstrucción venosa retiniana en los últimos años.

Among retinal vascular diseases, retinal venous occlusion is relatively frequent and due to its complications, it moderately or severely affects vision. The therapeutic options applied in macular edema and tractional retinal detachments caused by venous occlusions are several. A review of the scientific literature was performed to assess the efficacy and safety of the combined use of different therapies including intravitreal antiangiogenics and steroids with or without laser application, as well as pars plana vitrectomy as treatment alternatives for the complications of retinal venous occlusive disease. Even when antiangiogenics are considered as first line of treatment in retinal venous occlusion, in several cases there is better response in their combinations and steroids with laser. To resolve tractional retinal detachment and vitreous hemorrhage due to venous occlusions, a pars plana vitrectomy operation is mostly required. A search was made in electronic databases such as PubMed, Cochrane and other publications related to treatment alternatives for retinal venous obstruction in recent years.

Dexamethasone intravitreal implant as an adjuvant treatment for pediatric patients with Coats' disease / Implante intravítreo de dexametasona como tratamento adjuvante em pacientes pediátricos com doença de Coats

ABSTRACT We report two cases of stage 3A unilateral Coats' disease in pediatric patients. In both cases, disease control was achieved using a dexamethasone intravitreal implant in addition to other treatments. The treatment improved visual acuity in one patient and prevented the worsening of the decline in visual acuity in the other patient during follow-up periods of 7 and 3 years, respectively. One of the patients presented an increase in intraocular pressure, which was controlled with topical antiglaucoma medication, but developed a cataract that required surgery. In conclusion, dexamethasone intravitreal implant may be a useful adjuvant treatment to consider in some pediatric cases with Coats' disease.

RESUMO Relatamos dois casos de doença de Coats em estágio 3A unilateral em pacientes pediátricos. Em ambos os casos, o controle da doença foi obtido com implante intravítreo de dexametasona, além de outros tratamentos, com melhora da acuidade visual em um caso e sem piora da visão no outro, durante um período de acompanhamento de 7 e 3 anos. Um dos casos apresentou elevação da pressão intraocular controlada com medicação antiglaucoma tópica e desenvolveu catarata que exigiu cirurgia. Em conclusão, o implante intravítreo de dexametasona pode ser um tratamento adjuvante útil a ser considerado em alguns casos pediátricos com doença de Coats.

A bullous variant of central serous chorioretinopathy treated with oral spironolactone / Uma variante bolhosa da coriorretinopatia serosa central tratada com espironolactona oral

ABSTRACT We report the case of a 39-year-old male patient who presented with visual loss in the right eye for 6 weeks. The best-corrected visual acuity was counting fingers in the right eye and 20/30 in the left eye. The fundus examination demonstrated a right retinal detachment inferiorly extending to the fovea and a left macular serous detachment. After multimodal imaging study, the patient was diagnosed as having a bullous variant of central serous chorioretinopathy and treated with oral spironolactone associated with adjuvant laser photocoagulation. The retinal changes resolved after 6 months. The final visual acuity was 20/20 in both eyes.

RESUMO Relatamos o caso de um homem de 39 anos apresentando perda visual no olho direito há seis semanas. A melhor acuidade visual corrigida foi conta-dedos no olho direito e 20/30 no esquerdo. A fundoscopia demonstrou descolamento de retina direito inferiormente com extensão à fóvea e descolamento macular seroso à esquerda. Após estudos de imagem multimodal, o paciente foi diagnosticado com uma variante bolhosa de coriorretinopatia serosa central e tratado com espironolactona oral associada à fotocoagulação a laser adjuvante. As alterações retinianas resolveram após seis meses. A acuidade visual final foi 20/20 em ambos os olhos.

Factores relacionados al éxito anatómico y funcional de la cirugía por desprendimiento de retina regmatógeno. Instituto Regional de Oftalmología "Javier Servat Univazo" (2010 - 2019), Trujillo, Perú

Evaluar los factores relacionados al éxito anatómico y funcional de la cirugía por desprendimiento de retina regmatógeno (DRR) en pacientes del Instituto Regional de Oftalmología "Javier Servat Univazo". Estudio observacional en una cohorte retrospectiva de 204 pacientes con DRR sometidos a diferentes técnicas quirúrgicas entre enero 2010-diciembre 2019, con al menos 6 meses de seguimiento. Éxito anatómico (re-aplicación primaria de retina) y éxito funcional (mejoría de agudeza visual (AV)); buscándose asociación entre estas variables y las demográficas, clínicas y tiempos de espera. Resultados: La edad promedio fue 50 + 16,5 (9-85) años. Éxito anatómico se alcanzó en 165 (80,9 %) pacientes y funcional en 110 (52,9 %). Hubo menor tiempo de espera quirúrgico en pacientes que lograron éxito anatómico (20,0 +/- 22,6 días (1-120)) vs. (29,8 +/- 40,1 días (1-210)) (p=0,04) y en los que tuvieron éxito funcional ( 13,3+/- 15,1 (1-100)) vs. (31,9 +/- 33,7 (1-210)) (p <0,001); y menor tiempo de enfermedad y menor tiempo total en los que tuvieron éxito funcional (29,7 +/-56,5 días (1-365) vs. (61,9 +/- 110,6 días (1-730)) (p=0,008) y (43,1 +/- 68,1 (5-465)) vs. 93,8 +/- 118,3 (3-766)) respectivamente (p<0,001). El menor tiempo de espera quirúrgico mostró asociación con el éxito anatómico y funcional de la cirugía por DRR. El menor tiempo de enfermedad y el menor tiempo total también mostraron asociación con el éxito funcional. Recomendamos implementar medidas para abreviar tiempos de espera e instaurar una terapia quirúrgica precoz y oportuna en estos pacientes.

To evaluate factors related to the anatomical and functional success of surgery for rhegmatogenous retinal detachment (RRA) in patients of the Regional Institute of Ophthalmology "Javier Servat Univazo". retrospective cohort study of 204 patients with RRD submitted to different surgical techniques between January 2010-December 2019, with at least 6 months of follow-up anatomical success (primary retinal reapplication) and functional success (improvement in visual acuity (VA)); looking for an association between these variables and demographics, clinics and waiting times. Results: The mean age was 50 + 16.5 (9-85) years. Anatomical success was achieved in 165 (80.9%) patients and functional in 110 (52.9%). There was a shorter surgical waiting time in patients who achieved anatomical success (20.0 +/- 22.6 days (1-120)) vs (29.8 +/- 40.1 days (1-210)) (p=0.04) and in those who had functional success (13.3+/- 15.1 (1- 100)) vs (31.9 +/- 33.7 (1-210)) (p <0.001); and shorter sick time and shorter total time in those who had functional success (29.7 +/-56.5 days (1-365) vs (61.9 +/- 110.6 days (1-730)) (p=0.008) and (43.1 +/-68.1 (5-465)) vs 93.8 +/- 118.3 (3-766)) respectively (p<0.001). The shorter surgical waiting time was associated with RRD surgery's anatomical and functional success. The shortest time of illness and the shortest total time were associated with functional success. We recommend implementing measures to shorten waiting times and establish early and timely surgical therapy in these patients.

Surgical decisions and outcomes of rhegmatogenous retinal detachment during the coronavirus disease 2019 pandemic: Data from a tertiary referral center in Taiwan

Purpose: To assess changes in surgical decisions and outcomes of rhegmatogenous retinal detachment (RRD) during the COVID?19 pandemic at a tertiary center in Taiwan. Methods: Patients undergoing pars plana vitrectomy (PPV) or scleral buckling (SB) for primary RRD during Taiwan’s first wave of domestic COVID?19 cases surge between May and July 2021 (COVID cohort, n = 100) were compared to controls in the closest pre?COVID year, 2019 (pre?COVID cohort, n = 121). Results: The COVID cohort had significantly worse RRD presentation, received more PPV (alone or combined with SB (PPV + SB)) and less SB alone, and had comparable single?surgery anatomic success (SSAS) rates. In patients who underwent PPV, more underwent PPV + SB instead of PPV alone. The decision to combine SB in PPV surgery was significantly affected by the COVID pandemic (odds ratio [OR], 3.1860 [95% confidence interval (CI), 1.1487–8.8361]). However, a shorter duration of symptoms before the first presentation (0.9857 [95% CI, 0.9720–0.9997]) was the only factor related to SSAS, whereas the surgical method had no association. The SSAS rate remained close to or over 90% in patients with a duration of symptoms before surgery ?4 weeks but dropped to 83.3% in patients with duration >4 weeks. Conclusion: During the COVID?19 pandemic, worse RRD presentations led to a shift in preference for PPV over SB alone as the primary surgery. The pandemic affected surgeons’ decision to combine SB during PPV. Nevertheless, SSAS was only associated with the duration of symptoms but not with surgical methods.

Surgical management for treatment-resistant cases of inflammatory exudative retinal detachment: Mission impossible?

Purpose: To report the outcome of surgical intervention for inflammatory, exudative retinal detachment (ERD). Methods: A retrospective analysis of eyes with ERD that underwent vitrectomy. Results: Twelve eyes (10 patients) with ERD, non?responsive to medical therapy, underwent vitrectomy. The mean age was 35.7 ± 17.7 years. Five eyes (42%) had Vogt–Koyanagi–Harada disease, three (25%) had presumed tuberculosis (TB), two (17%) pars planitis, and one (8%) had sympathetic ophthalmia. The mean time of vitrectomy was 6.76 ± 4.1 months after onset. Six (50%) eyes had a recurrence, two settled with medical treatment, and four underwent re?surgery. The mean follow?up was 2.7 years. At the last visit, 10 (83.3%) eyes had attached retina; the best?corrected visual acuity (BCVA) had reduced to 1.6 ± 0.7 logarithms of the minimum angle of resolution (logMAR) from 1.3 ± 0.7 at baseline. Conclusion: Vitrectomy in ERD can act as an adjuvant to conventional medical therapy and help maintain structural integrity. Early vitrectomy may help preserve visual function.

Post-vitrectomy secondary macular holes: Risk factors, clinical features, and multivariate analysis of outcome predictors

Purpose: We report clinical characteristics, risk factors, treatment outcomes, and prognostic predictors of post?vitrectomy secondary macular holes (MHs). Methods: This was a retrospective observational case series from November 2014 to December 2020. Eyes that developed secondary MH, two weeks and beyond after primary vitrectomy for non?MH indications, were enrolled. Pre? and intraoperative records were screened to exclude pre?existence of MH. Eyes with multiple vitreoretinal surgeries prior to MH detection and tractional myopic maculopathy were excluded. Results: A total of 29 eyes of 29 patients with a mean age of 52 years developed secondary MH post?vitrectomy. The most common indications for primary vitrectomy were rhegmatogenous retinal detachment (RRD, 48.2%) and tractional retinal detachment (TRD, 24.1%). Time to MH detection after primary vitrectomy was 91.5 ± 117.6 days. The mean minimum hole diameter was 530 ± 298 microns. Epi?retinal membrane and cystoid degeneration was noted in 6 (20.7%) and 12 (41.3%) eyes, respectively (p = 0.088). The mean time from MH detection to MH repair was 34 ± 42 days. The surgical intervention included internal limiting membrane peeling with tamponade in 25 eyes. Overall, 80% showed anatomic hole closure, 90.9% versus 57.1% in the RRD and TRD (p = 0.092), respectively. The mean best?corrected visual acuity (BCVA) at the final visit was 0.71 logarithm of the minimum angle of resolution. Thirteen eyes (52%) had a BCVA of 20/100 or better. Minimal hole diameter (p = 0.029) only predicted final visual acuity. The interval between MH diagnosis and repair did not affect hole closure significantly (p = 0.064). Conclusion: Secondary MH post?vitrectomy closed successfully with limited visual improvement and trails behind idiopathic MH.

Clinical study of profile of retinal detachment in vasculitis and its management at tertiary eye care hospital

Purpose: The aim of the study was to understand the clinical profile and anatomical and visual outcome in Tractional/Combined (Tractional + Rhegmatogenous) Retinal Detachment due to vasculitis after surgical intervention. Methods: It was an interventional retrospective study of all cases who underwent surgery for RD with vasculitis at a single tertiary eye care center for over a period of 6 years. Patients with retinal detachment due to vasculitis were included in the study. All patients underwent the following surgical procedures: 240 belt buckle with three?port pars plana vitrectomy with membrane dissection and peeling with fluid gas exchange/with endolaser with silicon oil/C3 F8 gas injection. Results: In our study, 83.33% had preoperative vision of less than 6/60, whereas postoperatively 66.66% had vision of less than 6/60. Postoperatively 33.33% patients had vision better than 6/36. Of the six eyes operated for vasculitis with RD, retina was attached in five eyes following surgery. One patient had recurrent retinal detachment due to extensive proliferative vitreoretinopathy changes, and he was advised re?procedure but was lost for follow?up. The anatomical success was 83.33% on the first surgery. Conclusion: The overall anatomic success rate of retina reattachment surgery in vasculitis patient was good, and the visual outcome following the surgery can improve in majority of the cases. Hence, timely intervention is advocated.

Viscotrabeculotomy with anterior chamber irrigation versus Ahmed glaucoma valve implantation for silicone oil glaucoma in the pseudophakic eye / Viscotrabeculotomia com irrigação da câmara anterior versus implante de válvula de Ahmed para glaucoma por óleo de silicone em olho pseudofácico

ABSTRACT Purpose: To compare viscotrabeculotomy with anterior chamber irrigation to Ahmed glaucoma valve implantation for secondary glaucoma following silicone oil removal. Methods: A prospective study was conducted on 43 vitrectomized pseudophakic eyes with persistent glaucoma after silicone oil removal. Patients were randomized to either viscotrabeculotomy with anterior chamber irrigation or Ahmed glaucoma valve implantation. All patients were examined on day 1, week 1, and months 1, 3, 6, 9, 12, 18, and 24 postoperatively. Postoperative complications were noted. Success was defined as an intraocular pressure between 6 and 20 mmHg and with an intraocular pressure reduction of >30% compared with the preoperative intraocular pressure. Results: There were 22 eyes in the viscotrabeculotomy with anterior chamber irrigation and 21 eyes in the Ahmed glaucoma valve implantation group. The mean preoperative and postoperative intraocular pressure in the viscotrabeculotomy with anterior chamber irrigation and Ahmed glaucoma valve implantation groups were 35.5 ± 2.6 mmHg and 35.5 ± 2.4 mmHg and 16.9 ± 0.7 mmHg and 17.9 ± 0.9 mmHg respectively (p˂0.0001). There was a statistically significant intraocular pressure reduction at all follow-up time points compared to preoperative values (p˂0.0001) in both groups. The unqualified success rate in the viscotrabeculotomy with anterior chamber irrigation and Ahmed glaucoma valve implantation groups were 72.73% and 61.9%, respectively. A minimal self-limited hyphema was the most common complication. Conclusions: Both viscotrabeculotomy with anterior chamber irrigation and Ahmed glaucoma valve implantation are effective in lowering the intraocular pressure in glaucoma after silicone oil removal with viscotrabeculotomy with anterior chamber irrigation providing greater reduction, higher success rates, and minimal complications.

RESUMO Objetivo: Comparar a viscotrabeculotomia com irrigação da câmara anterior com o implante de válvula de glaucoma de Ahmed para glaucoma secundário após remoção de óleo de silicone. Métodos: Foi realizado um estudo prospectivo de 43 olhos pseudofácicos vitrectomizados com glaucoma persistente após a remoção de óleo de silicone. Os pacientes foram randomizados para viscotrabeculotomia com irrigação da câmara anterior ou implante de válvula de Ahmed. Todos os pacientes foram examinados no primeiro dia, na primeira semana e 1, 3, 6, 9, 12, 18 e 24 meses após a cirurgia. Observaram-se complicações pós-operatórias. O sucesso foi definido como uma pressão intraocular entre 6 e 20 mmHg e uma redução da pressão intraocular >30% em comparação com a pressão intraocular pré-operatória. Resultados: Foram designados 22 olhos para o grupo da viscotrabeculotomia com irrigação da câmara anterior e 21 olhos para o grupo do implante de válvula de Ahmed. A pressão intraocular média pré-operatória foi de 35,5 ± 2,6 mmHg para o grupo da viscotrabeculotomia com irrigação da câmara anterior e pós- e de 35,5 ± 2,4 mmHg no grupo do implante de válvula de Ahmed. e Os valores pós-ope­ratórios foram de 16,9 ± 0,7 mmHg e 17,9 ± 0,9 mmHg para esses mesmos grupos, respectivamente (p<0,0001). Ambos os grupos tiveram uma redução estatisticamente significativa da pressão intraocular em relação aos valores pré-operatórios (p<0,0001) em todos os momentos do acompanhamento. A taxa de sucesso não qualificado nos grupos da viscotrabeculotomia com irrigação da câmara anterior e do implante de válvula de Ahmed foi de 72,73% e 61,9%, respectivamente. A complicação mais comum foi o hifema, autolimitado e mínimo. Conclusões: Tanto a viscotrabeculotomia com irrigação da câmara anterior quanto o implante de válvula de Ahmed são eficazes na redução da pressão intraocular no glaucoma após injeção de óleo de silicone, mas a viscotrabeculotomia com irrigação em câmara anterior proporcionou maior redução da pressão intraocular e maiores taxas de sucesso, com complicações mínimas.

Síndrome uveomeningoencefálico Vogt Koyanagi-Harada con desprendimiento de la capa bacilar de la retina / Vogt Koyanagi-Barada uveomeningoencephalic syndrome with detachment of the bacillary layer of the retina

Introducción: El síndrome de Vogt-Koyanagi-Harada pertenece a los síndromes uveomeníngeos y es una de las principales enfermedades que amenazan la visión. Se caracteriza por una uveítis bilateral que se asocia frecuentemente con manifestaciones neurológicas, auditivas y tegumentarias. Recientemente un fenotipo particular de engrosamiento macular se ha descrito como desprendimiento bacilar asociado a esta enfermedad. Objetivo: Describir el desprendimiento bacilar de la retina mediante la tomografía de coherencia óptica de dominio espectral en un caso de Vogt Koyanagi Harada en fase uveítica. Presentación de caso: Paciente femenina de 46 años de edad atendida en el Instituto Cubano de Oftalmología "Ramón Pando Ferrer" con disminución de agudeza visual en ambos ojos y panuveitis bilateral. Fue diagnosticada con síndrome de Vogt-Koyanagi-Harada en su fase uveítica aguda con presencia de manifestaciones neurológicas y desprendimiento de la capa bacilar de la retina identificado mediante la tomografía de coherencia óptica de dominio espectral. Conclusiones: El síndrome de Vogt-Koyanagi-Harada aguda y el desprendimiento bacilar de la capa de la retina pueden diferenciarse de otros signos mediante la tomografía de coherencia óptica de dominio espectral. Su desaparición pudiera tener una relación con la mejoría de la agudeza visual(AU)

Introduction: Vogt-Koyanagi-Harada syndrome belongs to the uveomeningeal syndromes and is one of the major vision-threatening diseases. It is characterized by bilateral uveitis, which is frequently associated with neurological, auditory and integumentary manifestations. Recently a particular phenotype of macular thickening has been described as bacillary detachment associated with this disease. Objective: To describe bacillary retinal detachment using spectral domain optical coherence tomography in a case of Vogt Koyanagi Harada in uveitic phase. Case presentation: 46-year-old female patient attended at the Cuban Institute of Ophthalmology "Ramón Pando Ferrer" with decreased visual acuity in both eyes and bilateral panuveitis. She was diagnosed with Vogt-Koyanagi-Harada syndrome in its acute uveitic phase with presence of neurological manifestations and detachment of the bacillary layer of the retina identified by spectral domain optical coherence tomography. Conclusions: Acute Vogt-Koyanagi-Harada syndrome and bacillary retinal layer detachment can be differentiated from other signs using spectral-domain optical coherence tomography. Their disappearance could be related to the improvement of visual acuity(AU)

Afibercept treatment for macular edema with and without serous retinal detachment due to branch retinal vein occlusion / Tratamento com afibercepte para edema macular devido à oclusão da veia retiniana do ramo com e sem descolamento seroso da retina

ABSTRACT Purpose: To evaluate the effectiveness of intravitreal aflibercept treatment for macular edema with and without serous retinal detachment due to branch retinal vein occlusion. Methods: Thirty-seven eyes with branch retinal vein occlusion treated with intravitreal aflibercept injection for macular edema were evaluated retrospectively. The patients were divided into two groups according to whether they showed serous retinal detachment on spectral domain optical coherence tomography. Pro re nata regimen was applied after 1 dose of intravitreal aflibercept injection. After the initial injection, control treatments were administered at months 1, 2, 3, 6, and 12. The best-corrected visual acuity and central macular thickness were measured. Results: Fifteen patients had serous retinal detachment, and 22 with macular edema only (non-serous retinal detachment). The central macular thickness was significantly greater in the group with than in the group without serous retinal detachment (811.73 ± 220.68 µm and 667.90 ± 220.68 µm, respectively, p=0.04). The difference between the groups disappeared from the third month. The central macular thickness was similar between the two groups at the last control treatment (407.27 ± 99.08 µm and 376.66 ± 74.71 µm, p=0.66). The best-corrected visual acuity increased significantly in both groups. No significant difference was found between the two groups in terms of the best-corrected visual acuities at baseline and the final control. Conclusion: The intravitreal aflibercept treatment was highly effective in improving best-corrected visual acuity and central macular thickness in patients with branch retinal vein occlusion-induced macular edema independent of serous retinal detachment.

RESUMO Objetivo: Avaliar a eficácia do tratamento com aflibercepte intravítreo para edema macular devido à oclusão de um ramo da veia retiniana, com e sem descolamento seroso da retina. Métodos: Foram analisados retrospectivamente 37 olhos com oclusão de um ramo da veia retiniana, tratados com injeção intravítrea de aflibercepte para edema macular. Os pacientes foram divididos em dois grupos, de acordo com a presença ou ausência de um descolamento seroso de retina na tomografia de coerência óptica (SD-OCT). Um regime pro re nata foi seguido após 1 injeção intravítrea de aflibercepte. Após a injeção, foram realizadas consultas de acompanhamento nos meses 1, 2, 3, 6 e 12. Foram medidas a melhor acuidade visual corrigida e a espessura macular central. Resultados: Houve 15 pacientes com descolamento seroso de retina e 22 pacientes com apenas edema macular (descolamento não seroso de retina). A espessura macular central foi significativamente maior no grupo com descolamento seroso de retina do que no grupo com descolamento não seroso de retina (respectivamente, 811,73 ± 220,68 µm e 667,90 ± 220,68 µm; p=0,04). A diferença desapareceu a partir do terceiro mês. A espessura macular central foi semelhante nos dois grupos na última consulta (407,27 ± 99,08 µm e 376,66 ± 74,71 µm, p=0,66). A melhor acuidade visual corrigida aumentou significativamente em ambos os grupos. Não houve diferença entre os dois grupos quanto à melhor acuidade visual corrigida inicial e final. Conclusão: O tratamento com aflibercepte intravítreo foi altamente eficaz em melhorar a acuidade visual corrigida e a espessura macular central no edema macular induzido pela oclusão de um ramo da veia retiniana, independentemente da presença ou não de um descolamento seroso da retina.

Preeclampsia y eclampsia complicada con desprendimiento de retina. Comunicación de tres casos

La preeclampsia es un trastorno hipertensivo multisistémico que se presenta después de las 20 semanas de gestación en 5% a 15% de gestantes y es causa de complicaciones que pueden afectar órganos importantes y hasta provocar la muerte durante la gestación o en el posparto. Incluye la preeclampsia severa, eclampsia y síndrome HELLP (hemolysis, elevation of liver enzymes, low platelets, por sus siglas en inglés). Se comunica tres casos de desprendimiento de retina que ocurrieron en dos pacientes con preeclampsia severa y una con eclampsia, todas con hemorragia y alteración visual en el posparto que requirieron tratamiento farmacológico. El desprendimiento de retina es un síntoma asociado a la preeclampsia y eclampsia que puede ser investigado por fundoscopia ocular para determinar si es factible su tratamiento conservador o farmacológico.

Preeclampsia is a multisystemic hypertensive disorder that occurs after 20 weeks of gestation in 5%-15% of pregnant women and is the cause of complications that can affect important organs and even cause death during gestation or in the postpartum period. It includes severe preeclampsia, eclampsia and HELLP (hemolysis, elevation of liver enzymes, low platelets) syndrome. We report three cases of retinal detachment that occurred in two patients with severe preeclampsia and one with eclampsia, all with hemorrhage and visual alteration in the postpartum period that required pharmacological treatment. Retinal detachment is a symptom associated with preeclampsia and eclampsia that can be investigated by ocular fundoscopy to determine whether conservative or pharmacological treatment is feasible.

Desprendimiento bilateral de retina en una embarazada con síndrome de HELLP. Reporte de caso y revisión de la bibliografía / Bilateral retinal detachment in a pregnant woman with HELLP syndrome. Case report and literature review

Resumen ANTECEDENTES: El síndrome de HELLP es una complicación del embarazo que pone en riesgo la vida de la madre y el feto y es una variante del espectro de la preeclampsia, casi siempre relacionada con cambios visuales; las complicaciones, como el desprendimiento de retina, son excepcionales. CASO CLÍNICO: Paciente de 26 años, primigesta, con 36 semanas de embarazo y trastorno hipertensivo, tipo síndrome de HELLP, que se complicó con desprendimiento bilateral seroso de la retina que se resolvió espontáneamente. CONCLUSIONES: Las manifestaciones oculares relacionadas con la preeclampsia y el síndrome de HELLP suelen ser transitorias y se relacionan más con un síntoma de alarma que con un trastorno orgánico ocular. Es importante que las pacientes con este tipo de afecciones obstétricas reciban atención multidisciplinaria.

Abstract BACKGROUND: HELLP syndrome is a life-threatening complication of pregnancy in both mother and fetus. It manifests as a variant of the preeclampsia spectrum, almost always related to visual changes, complications, such as retinal detachment, are exceptional. CLINICAL CASE: A 26-year-old primigravida patient, 36 weeks pregnant, with hypertensive disorder, HELLP syndrome type, complicated by bilateral serous retinal detachment that resolved spontaneously. CONCLUSIONS: Ocular manifestations related to preeclampsia and HELLP syndrome are usually transient and are related more to an alarm symptom than to an organic ocular disorder. It is important that patients with these types of obstetric conditions receive multidisciplinary care.

Gas tamponade followed by laser treatment for macular retinal detachment secondary to optic pit / Tamponamento com gás seguido de laser para descolamento de retina secundário à fosseta de disco óptico

ABSTRACT Purpose: The study aimed to describe anatomic and visual outcomes associated with perfluoropropane intravitreal injection followed by laser treatment for macular retinal detachment secondary to optic disc pit. Methods: A single-center, retrospective study. Medical records of all patients treated at a tertiary retina referral center were evaluated between 2011 and 2018 for congenital optic disc pit-associated macular detachment with 0.3 ml 100% perfluoropropane intravitreal injection followed by retinal laser photocoagulation along the temporal optic disc margin as the initial treatment. Results: Six patients with optic disc pit-associated macular detachment were identified, with postoperative follow-up ranging from 13 to 52 months (mean: 28 months). Spectral domain optical coherence tomography (SD-OCT) showed complete fluid resolution without recurrence in five of the six cases. Four cases showed complete reabsorption after Intravitreal perfluoropropane plus laser, one patient needed an extra procedure (pars plana vitrectomy with inner limiting membrane peeling and pedicle flap inversion over the temporal optic disc margin) to achieve complete fluid reabsorption, and one patient had persistent intraretinal fluid and denied additional surgeries. The time between the initial procedure and total fluid reabsorption varied from 6.5 to 41 months (mean: 19.5 months). Best-corrected visual acuity improved after surgery on the last follow-up visit in all cases. Conclusion: 100% perfluoropropane intravitreal injection followed by photocoagulation along temporal optic disc margin was associated with anatomic and visual improvement in most cases, representing an alternative treatment approach for optic disc pit-associated macular detachment.

RESUMO Objetivo: Descrever os resultados anatômicos e visuais associados à injeção intravítrea de perfluoropropano seguida de tratamento a laser para descolamento de retina macular secundário à fosseta do disco óptico. Métodos: Estudo retrospectivo em um único centro. Foram revisados os prontuários médicos dos pacientes com descolamento macular associado a fosseta do disco óptico congênito em um centro de referência terciário de retina entre 2011 e 2018. Todos receberam como estratégia de tratamento inicial injeção intravítrea de perfluoropropano 100% seguido por fotocoagulação a laser ao longo da margem temporal do disco óptico. Resultados: Foram identificados seis pacientes com descolamento macular associado a fosseta do disco óptico durante o período do estudo. O seguimento pós-operatório variou de 13 a 52 meses, com média de 28 meses. SD-OCT demonstrou resolução completa do fluido em cindo dos seis casos, sem recorrência. Quatro casos apresentaram reabsorção completa após perfluoropropano intravítreo associado a laser, e um paciente necessitou de procedimento adicional (vitrectomia via pars plana com peeling da membrana limitante interna e inversão do retalho do pedículo sobre a margem temporal do disco óptico) para obter reabsorção completa de fluidos. Um paciente apresentou fluido intrarretiniano persistente e negou tratamentos adicionais. O tempo entre o procedimento inicial e a resolução completa do fluido variou entre 6,5 a 41 meses, com média de 19,5 meses. A acuidade visual corrigida melhorou após a cirurgia, considerando a última consulta de acompanhamento em todos os casos. Conclusão: A injeção intravítrea de perfluoropropano 100% seguida de fotocoagulação ao longo da margem temporal da margem do disco óptico foi associada à melhora anatômica e visual na maioria dos casos e representa uma abordagem terapêutica alternativa para o descolamento macular associado a fosseta do disco óptico.
