ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Objective:To evaluate the efficacy of scleral buckling in the treatment of retinal detachment (RD) secondary to familial exudative vitreoretinopathy (FEVR).Methods:An observational case series study was conducted.A total of 37 patients (42 eyes) of RD secondary to FEVR who were treated with scleral buckling in Beijing Tongren Hospital from July 2010 to March 2021 were enrolled.There were 30 males (35 eyes) and 7 females (7 eyes), with an average age of (15.21±5.42) years old.Scleral buckling under general anesthesia was performed in all patients.There were 22 eyes with rhegmatogenous RD (RRD), of which 21 eyes were treated with local external compression combined with cerclage, and 1 eye was treated with radial spinal compression.There were 13 eyes with tractive RD (TRD), of which 12 eyes were treated with local external compression combined with cerclage and subretinal fluid drainage, and 1 eye was treated with scleral buckling combined with vitrectomy.There were 7 eyes with RRD combined with TRD, of which 4 eyes were treated with local external compression combined with cerclage and subretinal fluid drainage, and 3 eyes were treated with scleral buckling combined with vitrectomy.The average follow-up time was (30.61±10.50) months.The main outcomes were best corrected visual acuity (BCVA) of the operated eye converted to the logarithm of the minimum angle of resolution, retinal reattachment rate, and incidence of complications.The study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Beijing Tongren Hospital, Capital Medical University (No.TRECKY2018-056-GZ[2022]-07). Written informed consent was obtained from each subject or their guardians before entering the cohort.Results:The average BCVA was 0.83±0.50 at last follow-up after surgery which was better than 1.10±0.39 before surgery, and the difference was statistically significant ( t=6.639, P<0.001). There were 39 eyes with retinal reattachment and 3 eyes without retinal reattachment.The reattachment rate was 95.45%(21/22) in RRD, 84.62%(11/13) in TRD, and 100%(7/7) in RRD combined with TRD.No serious complication occurred in any patients during postoperative follow-up. Conclusions:On the premise of optimized surgical strategy based on the indications of RD secondary to FEVR, scleral buckling has a high retinal reattachment rate in the treatment of RD secondary to FEVR.

ABSTRACT

AIM: To compare the effectiveness and complications of treating rhegmatogenous retinal detachment(RRD)with foldable capsule body(FCB)and scleral buckling(SB).METHODS: The clinical data of 81 patients(82 eyes)with RRD who underwent surgery at our hospital from March 2019 to April 2022 were retrospectively analyzed. The differences in retinal reattachment rate, best-corrected visual acuity, the absorption of subretinal fluid, postoperative discomfort and incidence of complications between the two treatments were compared.RESULTS: The retinal reattachment rate was 96% in the FCB group and 92% in the SB group, with no significant difference between the two groups(P&#x003E;0.05). The best corrected visual acuity of the affected macular eyes was different in the both groups(P&#x003C;0.01). Both groups effectively promoted the absorption of subretinal fluid. The operation time of FCB group was 16.50(12.75, 25.00)min, while it was 38.00(36.25, 41.75)min in the SB group(P&#x003C;0.001). Patients in the FCB group also had significantly lower eyelid swelling and pain symptoms than those in the SB group(P&#x003C;0.001). The visual analogue scale(VAS)score at 1d after operation was 1.00(0.00, 2.00)in the FCB group and 3.00(2.00, 3.00)in the SB group(P&#x003C;0.001).CONCLUSION: FCB is a safe and effective surgical method to treat RRD that can alleviate patient's pain. Furthermore, FCB has a significantly shorter operation time and milder postoperative adverse reactions than SB.

ABSTRACT

ABSTRACT Objective To assess pre-operative conditions that could influence primary anatomical success rate in a cohort of patients with rhegmatogenous retinal detachments (RRD) treated with primary vitrectomy and no scleral buckling. Methods A retrospective analysis was performed in a group of patients that underwent primary pars plana vitrectomy with gas tamponade and without scleral buckling for RRD between 2014 and 2019, with a minimum follow-up of 4 months. Results 305 eyes of 301 patients were included; 59.01% eyes were phakic, 39.01% were pseudophakic and 1.96% aphakic. 13.11% of patients had proliferative vitreoretinopathy grade B and 3.28% proliferative vitreoretinopathy grade C at the time of diagnosis while 83.61% had proliferative vitreoretinopathy grade 0 or A. 53.1% had superior breaks, 15.4% inferior breaks and 31.5% a combination of both. Primary success rate was obtained in 90.82% of eyes (95%CI 87.58-94.06). 9.18% of eyes (95%CI 5.94-12.42) re-detached. In 3.27% the cause of re-detachment was proliferative vitreoretinopathy, and in the remaining 5.90% because of a new or a missed break, the leakage of a previously treated break, or an area of shallow peripheral detachment with no detectable break. Of 181 phakic eyes, 10.49% re-detached, whereas in over 126 aphakic or pseudophakic eyes 7.75% re-detached (p=0.42). 16.39% eyes of the entire cohort had preoperative grade B or C proliferative vitreoretinopathy, whereas 32.14% of re-detached eyes had preoperative grade B or C proliferative vitreoretinopathy (95%CI 17.29-46.99; p=0.02). Th eyes that re-detached after the first surgery had a mean of 2.5 (95%CI 1.86-3.13) retinal tears, against a mean of 1.87 (95%CI 1.73-2.00) retinal tears of those that did not re-detach after the first surgery (p=0.02). Conclusion We found location of breaks and lens status to be independent factors not related to a lower single operation success rate, whereas the number or size of breaks and preoperative proliferative vitreoretinopathy stages B or C were independent factors related to a higher likelihood of re-detachment.


RESUMO Objetivo Avaliar condições pré-operatórias que poderiam influenciar a taxa de sucesso anatômico primário em uma coorte de pacientes com descolamento de retina regmatogênico tratada com vitrectomia primária e sem introflexão escleral. Métodos Foi realizada uma análise retrospectiva em um grupo de pacientes submetidos a vitrectomia primária pars plana com tamponamento gasoso e sem introflexão escleral por desprendimento de retina regmatogênico entre os anos 2014 e 2019, com monitoramento mínimo de 4 meses. Resultados Foram incluídos 305 olhos de 301 pacientes; 59,01% dos olhos eram fáquicos, 39,01% eram pseudofáquicos, e 1,96% era afáquico; 13,11% dos pacientes tinham vitreorretinopatia proliferativa grau B, e 3,28%, vitreorretinopatia proliferativa grau C no momento do diagnóstico, enquanto 83,61% tinham vitreorretinopatia proliferativa grau 0 ou A; 53,1% tinham rasgaduras superiores; 15,4%, rasgaduras inferiores e 31,5%, uma combinação de ambas. A taxa de sucesso primário foi obtida em 90,82% dos olhos (IC95% 87,58-94,06); 9,18% dos olhos (IC95% 5,94-12,42) se redestacaram. Em 3,27%, a causa do redescolamento foi vitreorretinopatia proliferativa e, nos 5,90% restantes, por causa de uma ruptura nova ou perdida, o vazamento de uma ruptura previamente tratada, ou uma área de descolamento periférico superficial sem ruptura detectável. Dos 181 olhos fáticos, 10,49% redestacaram-se, enquanto em mais de 126 olhos afáquicos ou pseudofáquicos 7,75% redestacaram-se (p=0,42); 16,39% dos olhos de toda a coorte tinham vitreorretinopatia proliferativa pré-operatória grau B ou C, enquanto 32,14% dos olhos redescolados tinham vitreorretinopatia proliferativa pré-operatória grau B ou C (IC95% 17,29-46,99) (p=0,02). Os olhos que se redescolaram após a primeira cirurgia tiveram média de 2,5 (IC95% 1,86-3,13) lágrimas retinianas, contra uma média de 1,87 (IC95% 1,73-2,00) lágrima retiniana daqueles que não se redestacaram após a primeira cirurgia. (p=0,02). Conclusão A localização das rasgaduras e o status da lente são fatores independentes não relacionados a uma menor taxa de sucesso da operação, enquanto o número ou o tamanho das rasgaduras e estágios vitreorretinopatia proliferativa pré-operatórios B ou C foram fatores independentes relacionados a uma maior probabilidade de redescolamento.

ABSTRACT

Purpose: The study was conducted to determine the ocular pulse amplitude (OPA) changes, measured with a dynamic contour tonometer (DCT), after surgical retinal detachment repair. Methods: This was a prospective and comparative study. Thirty patients (30 eyes) who had undergone uncomplicated unilateral scleral buckling and encircling procedures for quadrant or half?retinal rhegmatogenous retinal detachment were referred for DCT one day before the surgery was performed, on the 1st, 7th, and 30th postoperative day. Methods of descriptive (arithmetical mean, standard deviation) and analytical statistics (analysis of variance) were used to analyze the data and evaluate the significance of the difference. A value of P less than 0.05 was considered statistically significant. The data were evaluated for normality with the single?sample Kolmogorov–Smirnov test. Results: OPA values decreased significantly after scleral buckling procedures (p < 0.0001), but regained near to preoperative values one month after the surgery. Conclusion: OPA tends to decrease after retinal detachment surgery. Restoring patients’ vision with scleral buckling and encircling procedures gives early changes in blood supply to the choroid and ocular nerve, and since OPA is an indirect parameter of choroidal vascularization, measuring these values can help make an insight into ocular hemodynamics.

ABSTRACT

Purpose: To evaluate the efficacy and safety of hybrid 26?gauge needle drainage in scleral buckling for rhegmatogenous retinal detachment (RRD). Methods: In this retrospective study, we included patients who underwent scleral buckling surgery along with subretinal fluid (SRF) drainage using the ‘Hybrid 26G needle drainage technique’. Pre?operative assessment included the best corrected visual acuity (BCVA), lens status, and extent of retinal detachment. Intra?operative surgical details such as the height of retinal detachment, number of attempts required to drain the fluid, amount of fluid drained, adequacy of break buckle relationship, and any intra?operative or post?operative complications were noted. Post?operatively, the final visual outcome and retina status were assessed at 3 months of follow?up. Results: A total of 10 eyes with primary RRD and proliferative vitreoretinopathy C1 or less were included. Pre?operatively, the mean BCVA was 2.43 ± 1.01 logMAR units, which improved significantly to 0.679 ± 0.45 logMAR units (p value < 0.05) at 3 months of follow?up. Regarding the extent of RRD, five eyes (50%) had a total detachment, two eyes (20%) had a sub?total detachment, and three eyes (30%) had an inferior detachment. Four eyes had shallow detachment, four had a moderate detachment, and two eyes had bullous detachment. Complete drainage of SRF (>75%) was achieved in five patients, and a partial but adequate drainage (50–75%) was achieved in the rest of the five patients. In none of the patients, inadequate or dry tap was encountered. No intra?operative complications were encountered. The retina was attached in eight out of ten eyes at 1 week and at a 1?month follow?up period. Two patients required pars plana vitrectomy for persistent SRF. The retina was attached in all the patients at 3 months of follow?up. Conclusion: The ‘Hybrid needle drainage’ technique is a safe and effective technique for SRF drainage in scleral buckling surgery

ABSTRACT

ABSTRACT Purpose: To investigate the incidence, risk factors, and visual outcomes of epiretinal membrane development following rhegmatogenous retinal detachment repair. Methods: This was a retrospective study of 309 eyes that underwent initial surgery for primary uncomplicated rhegmatogenous retinal detachment. Examinations were conducted preoperatively and then postoperatively at 1, 3, 6, and 12 months. The study patients were categorized into two groups depending on the presence or absence of the epiretinal membrane. Results: The incidence of postoperative epiretinal membrane was 28.5%; 42.7% of these patients had severe epiretinal membrane development and therefore underwent the epiretinal membrane removal. Logistic regression analyses revealed that giant retinal tears (OR: 2.66; 95% CI: 1.045-6.792, p=0.040) and horseshoe tears (OR: 0.534; 95% CI: 0.295-0.967, p=0.039) were the significant predictors of postoperative epiretinal membrane. Triamcinolone acetonide staining was significantly associated with the prevention of epiretinal membrane (p=0.022). A total of 34 patients showed a better or an equal final best-corrected visual acuity; of which 4 eyes were evaluated at the final follow-up visit and exhibited a reduced best-corrected visual acuity. Conclusion: Our analysis demonstrated that horseshoe tears and giant retinal tears represent the risk factors for the postoperative epiretinal membrane. Triamcinolone acetonide staining had a significant preventive effect on the postoperative epiretinal membrane. Furthermore, a second round of pars plana vitrectomy, including membrane removal, led to a significant improvement in the final best-corrected visual acuity as per the last follow-up examination, albeit the recovery was limited.


RESUMO Objetivos: Investigar a incidência, fatores de risco e desfechos visuais do desenvolvimento da membrana epirretiniana após reparo do descolamento regmatogênico da retina. Métodos: Trata-se de um estudo retrospectivo de 309 olhos submetidos à cirurgia inicial para descolamento regmatogênico da retina primário sem complicações. Os exames foram realizados no pré-operatório aos 1, 3, 6 e 12 meses pós-operatórios. Os pacientes foram divididos em dois grupos, dependendo da presença ou ausência de membrana epirretiniana. Resultados: A incidência de membrana epirretiniana pós-operatória foi de 28,5%; 42,7% desses pacientes apresentaram desenvolvimento grave da membrana epirretiniana e, portanto, foram submetidos à remoção desta membrana. A regressão logística mostrou que as lágrimas retinianas gigantes (RC: 2,66; 95% IC: 1,045 - 6,792, p=0,040) e lágrimas em ferradura (RC: 0,534; 95% IC: 0,295-0,967, p=0,039), foram preditores significativos de membrana epirretiniana pós-operatória. A coloração com acetonida de triancinolona foi significativamente associada à prevenção da membrana epirretiniana (p=0,022). Trinta e quatro pacientes apresentaram acuidade visual melhorada, ou igual, ou acuidade visual final melhor corrigida; 4 olhos foram avaliados na consulta final de acompanhamento e apresentaram redução da acuidade visual melhor corrigida. Conclusão: Nossa análise demonstra que as lágrimas de ferradura e as lágrimas retinianas gigantes representam fatores de risco para a membrana epirretiniana pós-operatória. A coloração com acetonida de triancinolona teve um efeito preventivo significativo na membrana epirretiniana no pós-operatório. Além disso, uma segunda rodada de vitrectomia pars plana, incluindo remoção da membrana, levou a uma melhora significativa da acuidade visual final melhor corrigida na última consulta de acompanhamento, embora a recuperação tenha sido limitada.

ABSTRACT

Purpose In non-drainage scleral buckling, anterior chamber paracentesis is usually carried out to decrease intraocular pressure. When the buckling is extensive however, this technique may be inefficient and time consuming. In this study, we tried to determine if a mini 25-gauge pars plana vitrectomy could be used as an efficient and safe alternative procedure to anterior chamber paracentesis for adjusting intraocular pressure during a non-drainage scleral buckling. Methods In this case series, 44 patients with rhegmatogenous retinal detachment (proliferative vitreoretinopathy stage < C) were included. In all cases, a mini 25-gauge pars plana vitrectomy was performed before buckle fixation and repeated if necessary. Complete retinal attachment was defined as the anatomical success. Results Forty-four eyes of 44 patients with mean age of 48.1 ± 18.2 years were included. Silicon buckle nº 276, sponge 505, and sponge 507 were utilized for 7, 34, and 3 eyes, respectively. Intravitreal injection of SF6 gas was performed for 54.5% of the eyes. Mean total time of the operation was 61 ± 16 min and the mean time for vitrectomy was 87 ± 31 s. Complete retinal attachment in 37 and incomplete attachment in 4 eyes were achieved after single operation that was a success rate of 93.2%. One had more than usual vitreous leak at the site of scleretomy and one developed a tiny vitreous hemorrhage at the sclerotomy site. Three sclerotomy sites needed suturing. Conclusion The anatomical outcome and the safety observed in this study were comparable to the current methods reported in the literature. Therefore, if anterior chamber paracentesis fails to adjust intraocular pressure during a non-drainage scleral buckling, performing a small gauge mini vitrectomy is safe and helpful.

ABSTRACT

Purpose: To report the clinical profile, management, and long?term anatomical and visual acuity (VA) outcomes of pediatric macula?off rhegmatogenous retinal detachment (RRD) secondary to familial exudative vitreoretinopathy (FEVR). Methods: This was a prospective, interventional study of 14 eyes of 13 children aged ?18 years with macula?off FEVR?RRD. The primary outcomes were anatomical reattachment and VA changes. Results: The mean (±SD) age of the study population was 12.14 (±3.23) years (range 6–18 years) with a male preponderance (M:F – 10:3). Of the 14 eyes, 10 underwent vitrectomy with silicone oil injection, while four underwent scleral buckling surgery. Significant improvement in VA was noted at a mean (±SD) follow?up duration of 3.32 (±1.34) years, with the mean (±SD) LogMAR VA improving from 1.42 (±0.48) (Snellen equivalent 2/60; range from 6/36 to counting finger close to face [CFCF]) to 0.6 (±0.31) (Snellen equivalent 6/24; range 6/9–6/36) (P < 0.00001) at the final visit. Successful anatomical reattachment was achieved in 13/14 eyes (92.85%). Screening of the other eye and family members was performed for FEVR and treated with laser photocoagulation when deemed necessary (7/10 contralateral eye; 12/20 siblings; 0/24 parents). Conclusion: To conclude, RRD may arise in eyes with FEVR at a young age and with a male predilection in Indian population. Timely surgical intervention by scleral buckling procedure or vitrectomy, based on the patient profile, can achieve excellent anatomical and VA outcomes. Careful clinical and angiographic screening of the other eye and family members is vital.

ABSTRACT

Rhegmatogenous retinal detachment (RRD), the most common type of retinal detachment, is the separation of neurosensory retina from the underlying retinal pigment epithelium. The key to surgical treatment of RRD is to find and seal all retinal breaks while the major surgical procedures include scleral buckle (SB), pars plana vitrectomy (PPV), and a combination of the two (PPV/SB). Different surgical methods have their own advantages and limitations. SB plays a very important role in certain types of RRD, providing a high rate of anatomical reduction and a good prognosis of visual function. Combined PPV is also an important auxiliary means for the treatment of complicated RRD. The rapid development of vitreoretinal surgery has greatly contributed to the trend of RRD surgery from extraocular to intraocular. However, it is worth noting that personalized RRD surgical methods are needed to be provided for different patients in order to minimize the occurrence of complications.

ABSTRACT

AIM: To observe the changes of the morphology and structure of macula, blood flow density of macula and optic disc, as well as retinal nerve fiber layer thickness by optical coherence tomography(OCT)and optical coherence tomography angiography(OCTA)in patients with rhegmatogenous retinal detachment(RRD)under went sclera buckling(SB). METHODS: As a cross-sectional case-controlled study, 25 patients(25 eyes)were diagnosed with RRD in the department of ophthalmology, Ganzhou People's Hospital from July 2014 to March 2021. The differences in the vascular density(VD)of superficial vessel cluster(SVC), the VD of deep vessel cluster(DVC)of macula, the SVC-VD of optic disc, retinal nerve fiber layer(RNFL), central macular thickness(CMT), subfoveal choroidal thickness(SFCT)and outer structure of macula between the affected eyes and healthy eyes at the last post-operative follow-up were compared, and the correlation indicators affecting best corrected visual acuity(BCVA, LogMAR)of the affected eyes at the last follow-up were analyzed. RESULTS: There were no statistically significant in SVC-VD and DVC-VD of macula, SVC-VD of optic disc, RNFL, CMT, SFCT between the affected eyes and healthy eyes at the last post-operative follow-up(all P&#x003E;0.05); At the last follow-up visit, the comparison of macular outer structure on OCT between the affected eyes and the healthy eyes showed that the light band integrity of the external limiting membrane(ELM), myoid zone(MZ), ellipsoid zone(EZ)and outer segment of photoreceptor(OS)had no statistically significant difference(all P&#x003E;0.05), while the light band integrity of interdigitation zone(IZ)had significant difference(P=0.014); The difference of BCVA(LogMAR)between the affected eyes and the healthy eyes at the last follow-up was statistically significant(P=0.002). There was significant correlation between BCVA(LogMAR)of affected eyes at the last post-operative follow-up and the presence or absence of macular involvement, the correlated with SVC-VD of optic disc, the integrity of the light bands of ELM, MZ, EZ, OS and IZ on the outer structure of macula, it was positively correlated with the presence or absence of macular involvement(rs=0.401, P=0.047)and it was negatively correlated with SVC-VD of optic disc, the integrity of the light bands of ELM, MZ, EZ, OS and IZ on the outer structure of macula(all P&#x003C;0.05).CONCLUSION: The OCT and OCTA can be used to observe fundus changes after SB surgery for RRD to obtain long-term follow-up information related to vision prognosis, and visual prognosis depends on the recovery of retinal outer structure, and the integrity of IZ structure is more important for visual recovery; The SVC-VD of optic disc is correlated with visual prognosis, and whether it was correlated with intraocular pressure require further observation and verification with postoperative continuous data.

ABSTRACT

Objetivo: Determinar los resultados de la técnica quirúrgica de identación escleral y la de retinopexia neumática en el desprendimiento regmatógeno de retina. Métodos: Se realizó un estudio descriptivo, longitudinal y prospectivo en pacientes operados con la técnica de identación escleral y la de retinopexia neumática en el Centro Oftalmológico de Villa Clara entre junio de 2019 y diciembre de 2020. Resultados: Los hombres fueron los más afectados y la edad media fue de 57,5 años. En el 72,7 por ciento la rotura causante del desprendimiento fueron los desgarros en herradura. La media del tiempo de evolución de la enfermedad fue de 7,2 días y el 77,3 por ciento de los ojos presentaba mácula desprendida al momento del diagnóstico. El 68,2 por ciento tuvo una agudeza visual mejor corregida preoperatoria < 20/200. Los pacientes con mácula desprendida preoperatoria alcanzaron como media una agudeza visual final de 0,4 ± 0,3 (desviación estándar). En el 86,4 y el 77,3 por ciento de los ojos se lograron buenos resultados anatómicos y funcionales finales. Las membranas epirretinales se presentaron como complicación posoperatoria en ambas técnicas quirúrgicas y el líquido subretinal residual solo en la retinopexia neumática. Conclusiones: El desprendimiento regmatógeno de retina se presenta con pobre agudeza visual preoperatoria. Con ambas técnicas quirúrgicas, en pacientes con ninguna o mínima vitreorretinopatía proliferativa, se logran buenos resultados anatómicos y funcionales.


Objective: Determine the results of the surgical technique of scleral buckling and neumatic retinopexy in rhegmatogenous retinal detachment. Methods: A prospective longitudinal descriptive study was conduced of patients undergoing scleral buckling and neumatic retinopexy at Villa Clara Ophthalmology Center from June 2019 to December 2020. Results: Male gender prevailed; mean age was 57.5 years. In 72.7 percent of the cases the retinal break causing the detachment was a U-shaped tear. Mean time of evolution of the disease was 7.2 days, and 77.3 percent of the eyes had a detached macula at diagnosis. In 68.2 percent preoperative best corrected visual acuity was <20/200. Patients with a preoperative detached macula achieved a mean final visual acuity of 0.4 ± 0.3 (standard deviation). Good final anatomical and functional results were obtained in 86.4 percent and 77.3 percent of the eyes. Epiretinal membranes were a postoperative complication in both surgical techniques, whereas residual subretinal fluid was a complication only in neumatic retinopexy. Conclusions: Rhegmatogenous retinal detachment presents with poor preoperative visual acuity. Both surgical techniques obtain good anatomical and functional results in patients with minimum or no proliferative vitreoretinopathy(AU)

ABSTRACT

Myopic foveoschisis (MF) has mild early symptoms, however, its course is progressive. When the secondary macular detachment or macular hole occurs, it can cause severe vision loss. Therefore, it is generally believed that MF patients should undergo surgical intervention early after the onset of symptoms to prevent them from further developing into a macular hole or macular hole retinal detachment.It is generally believed that the traction of the vitreous cortex and posterior scleral staphyloma to the retina plays an important role in the occurrence and development of MF. The operation mode is divided into vitreoretinal surgery and macular buckling, the former release the retinal traction via the vitreous body and the latter reattaches the retina via the extrascleral approach. There is no consensus on whether to perform internal limiting membrane peeling and gas tamponade in vitreoretinal surgery and the fovea-sparing internal limiting membrane peeling has become a hot topic in recent years. Compared with vitreoretinal surgery, macular buckling can release the traction of the retina caused by posterior scleral staphyloma, but it cannot relieve the traction in the tangential direction of the retina. Vitreoretinal surgery and extrascleral surgery seems to make up the shortcomings of both, however, the effect of treatment on patients still needs further verification. In clinical work, it is necessary to conduct individualized analysis of MF patients, weigh the advantages and disadvantages of each operation, and choose the most suitable operation mode for patients with different conditions. In the future, the emphasis of our work is to develop operation mode with great curative effect and less complications.

ABSTRACT

@#AIM: To evaluate the outcome of scleral buckling(SB)in patients with rhegmatogenous retinal detachment(RRD)with subretinal proliferation. <p>METHODS: This was a retrospective clinical analysis research. Patients with RRD associated with subretinal proliferation who visited the Beijing Tongren Hospital were included in this study. From October 2016 to January 2020. There were 54 patients, including 36 males and 18 females, with the average age of 24.92±11.99 years. The retinal detachment range <1, 1-2 and >2 quadrants were 12, 25 and 17 eyes, respectively. The macula was involved in 47 eyes. Subretinal proliferation range <1, 1-2 and >2 quadrants were 26, 23 and 5 eyes, respectively. The average Logarithm of the minimum angle of resolution(LogMAR)best corrected visual acuity(BCVA)was 1.21±0.77, all patients were treated with SB under general anesthesia and the anatomical retinal reattachment, visual acuity and complications were observed.<p>RESULTS: The retina was reattached in 52 eyes(96%), and 2 eyes(4%)needed pars plana vitrectomy for retinal redetachment. The mean follow wp was 19.17±11.15mo. The BCVA improved from 1.21±0.77 LogMAR before surgery to 0.61±0.40 LogMAR after surgery(<i>P</i><0.01). No serious complications occurred. <p>CONCLUSION: Under the circumstance of correct selection of indications, SB was highly successful in eyes with RRD associated with subretinal proliferation.

ABSTRACT

@#AIM: To investigate the correlation between macular mierostructure changes and visual outcomes after scleral buckling for macular-off primary rhegmatogenous retinal detachment(RRD)by three-dimensional optical coherence tomography(3D-OCT).<p>METHODS: Retrospective case review, the clinical data of scleral buckling in 30 eyes of 30 cases of RRD involving macular area were analyzed retrospectively. The changes of ellipsoid zone(EZ), external 1imiting membrane(ELM), subretinal fluid(SRF)and central retinal thickness(CRT)were observed and the relationship between them and best corrected visual acuity(BCVA)was analyzed by 3D-OCT at 2d, 2wk, 1, 3 and 6mo after operation.<p>RESULTS: Postoperative SRFH and CRT showed a descended trend. Postoperative BCVA showed an ascendant trend. Multiple comparisons: there were significant difference in each groups except SRFH(2wk <i>vs</i> 1mo, <i>P</i>>0.05), CRT(2d <i>vs</i> 2wk, <i>P</i>>0.05), BCVA(2d <i>vs</i> preoperation, 2wk <i>vs</i> preoperation, <i>P</i>>0.05). There are four forms of EZ and ELM::9 eyes, intact ELM and EZ(EZ+ELM+); B: 7 eyes, intact ELM with disrupted EZ:(EZ-ELM+); AC: 6 eyes, intact EZ with disrupted ELM:(EZ+ELM-); D: 8 eyes, disrupted ELM and EZ:(EZ-ELM-), the BCVA of the above four types are 0.15±0.04, 0.50±0.06, 0.54±0.05 and 0.59±0.09, there were significant difference in each groups except(C <i>vs</i> B, <i>P></i>0.05)and(C <i>vs</i> D, <i>P</i>>0.05). The incidence of SRF was 87% 2d after operation, 46.6% patients had persistent SRF at 6mo after operation. Postoperative CRT was positively correlated with postoperative SRFH.<p>CONCLUSION: After scleral buckling, the macular microstructure showed dynamic changes. The effect of SRF may be manifested as BCVA delayed recovery. With the slow absorption of SRF, CRT decreased and BCVA increased. The intact ELM or EZ shows better vision, but the disrupted ELM means worse vision.

ABSTRACT

@#Surgery is the most effective treatment of rhegmatogenous retinal detachment(RRD)which is the most common type of retinal detachment. Nowdays, the postoperative retinal anatomic reattachment is evaluated by indirect ophthalmoscope, optical coherence tomography(OCT), ocular ultrasonography and <i>etc.</i> which are also helping ophthalmologist in diagnosis of RRD. Postoperative visual function is mainly confirmed by the best corrective visual acuity(BCVA), which is mostly chosen by ophthalmologist in prognosis evaluation. However, there were patients with terrific postoperative retinal anatomic reattachment, who should have achieved the BCVA. The factors and the probable mechanism which affect the postoperative visual function of RRD would be summarized in this paper.

ABSTRACT

@#AIM: To compare the postoperative outcomes after segmental scleral buckling(SSB)surgery with minimal <i>in situ</i> conjunctival incision(MCI)and conventional limbal conjunctival incision(LCI). <p>METHODS: Prospective randomized controlled study. Eighty eyes of 80 patients with rhegmatogenous retinal detachment(RRD)who received SSB surgeries in our hospital from August 2016 to November 2018 were recruited. They were randomly divided into two groups. Patients in control group were performed with conventional LCI, while patients in observation group received MCI. The length of the surgery, the retinal reattachment rate and the visual analogue scale(VAS)for evaluating the pain on the first postoperative day, questionnaire scoring method for evaluating the postoperative comfort level(including foreign body sensation and tearing)on the first, seventh, fourteenth, and thirtieth days were recorded. <p>RESULTS: The difference of surgery time between the control group and the observation group was statistically significant(<i>t</i>=2.057, <i>P</i><0.05). There was no significance in retinal reattachment rate between two groups. At the first day after surgery, the postoperative pain of the observation group was significantly lower than the control group(<i>P</i><0.05). At the first and seventh day after surgery, the observation group had higher postoperative comfort questionnaire score than the control group(<i>P</i><0.01), however, at the fourteenth and thirtieth day after surgery, the score was similar between the two groups(<i>P</i>>0.05). <p>CONCLUSION: Using MCI in SSB operation could shorten the operation time and significantly reduced postoperative pain and discomfort level.
