ABSTRACT
ABSTRACT A 42-year-old female patient had vision loss and chronic epiphora in her left eye. Her best-corrected visual acuity was 10/10 in the right eye and 0.3/10 in the left eye. The anterior segment examination results were normal. In fundus examination, choroidal folds were detected. Optical coherence tomography showed elevation on the macula and choroidal folds. Ultrasonography revealed a T-sign. Magnetic resonance imaging revealed an ethmoidal mucocele that compresses the orbital tissues. Surgical treatment was performed in the otorhinolaryngology department. Postoperatively, choroidal folds recovered, and the best-corrected visual acuity improved, but subretinal fluid accumulated. During the follow-up period without any treatment, subretinal fluid totally disappeared.
RESUMO Paciente do sexo feminino, 42 anos, com perda visual e epífora crônica no olho esquerdo. Sua acuidade visual melhor corrigida foi de 10/10 no olho direito e 0,3/10 no olho esquerdo. O exame do segmento anterior foi normal. No exame de fundo de olho, foram detectadas pregas coroidais. A tomografia de coerência óptica revelou elevação na mácula e pregas coroidais. A ultrassonografia revelou sinal T. A imagem de ressonância magnética mostrou mucocele etmoidal que comprime os tecidos orbitários. O Departamento de Otorrinolaringologia realizou o tratamento cirúrgico. No pós-operatório, as dobras coroidais se recuperaram, a acuidade visual melhor corrigida foi melhorada, mas ocorreu líquido sub-retiniano. Durante o período de acompanhamento sem qualquer tratamento, o líquido sub-retiniano recuperou-se totalmente.
ABSTRACT
La neurorretinopatía macular aguda es una condición rara con patogenia microvascular. Se presenta con un inicio agudo con escotomas paracentrales correspondientes a lesiones paramaculares evidentes. Los avances en las imágenes multimodales permitieron caracterizar este trastorno de retina y crear nuevos conceptos. Serraf, en el 2013, identificó dos formas por medio de la tomografía de coherencia óptica dominio espectral: el tipo 1 conocido como maculopatía paracentral aguda media en la cual se observa una banda hiperreflectiva en la capa nuclear interna, y el tipo 2 en el cual la banda hiperreflectiva se ubica en la capa nuclear externa, que involucra la zona elipsoide y la zona de interdigitación con el epitelio pigmentario de la retina. Hasta el momento no existe cura; pero se puede actuar sobre los factores de riesgo. Por ser una condición rara y por no existir reportes hasta el momento en Cuba es que se presentan a continuación dos pacientes con cuadros clínicos similares de estas dos variantes; concluyendo la importancia que presentan las imágenes multimodales como medio auxiliar diagnóstico.
Acute macular neuroretinopathy is a rare condition with complex pathogenesis and microvascular cause. It appears with acute onset, with paracentral scotomas corresponding to obvious paramacular lesions. Advances in multimodal imaging made it possible to characterize this retinal disorder and to create new concepts. Serraf, in 2013, identified two forms by spectral domain optical coherence tomography: type 1, known as paracentral acute middle maculopathy, in which a hyperreflective band is observed in the inner nuclear layer; and type 2, in which the hyperreflective band is located in the outer nuclear layer, involving the ellipsoid zone and the zone of interdigitation with the retinal pigment epithelium. Up to this moment, there is no cure; but it is possible to act on the risk factors. Because it is a rare condition and because there are no reports so far in Cuba, two patients with similar clinical pictures of these two variants are presented; concluding the importance of multimodal images as an auxiliary diagnostic tool.
ABSTRACT
Purpose: To analyze the imaging characteristics and the clinical course of patients showing concomitant paracentral acute middle maculopathy (PAMM) and acute macular neuroretinopathy (AMN) post?blunt trauma. Methods: PAMM and AMN lesions post?blunt trauma diagnosed on enhanced depth imaging optical coherence tomography (EDI?OCT) were recruited for the study. Results: Thirteen eyes of 13 individuals with a history of blunt trauma were included in the study, of whom 11 (85%) were males. Mean age of the patients was 33.62 (range 16–67) years. Mean visual acuity at presentation and the last visit was 1.67 log of minimum angle of resolution (logMAR) and 0.82 logMAR, respectively. Mean interval between trauma and imaging was 5.08 (range 1–15) days. All patients had unilateral involvement, with the right eye being involved in 10 patients (77%). All patients had concomitant PAMM and AMN lesions. Conclusion: Presence of coincident PAMM and AMN suggests a common pathophysiologic etiology, but the description of concomitant PAMM and AMN in the setting of blunt trauma to eye is hitherto unreported. Identifying AMN in a setting of PAMM requires meticulous examination of the OCT and OCTA images. It can be a cause of suboptimal visual recovery in such eyes.
ABSTRACT
La maculopatía por inmunoganmapatía es una enfermedad macular inusual caracterizada por la presencia de fluido intra y subretinal en asociación con ganmapatías monoclonales. Puede constituir la primera manifestación de enfermedad sistémica en un número considerable de pacientes. La infiltración de la retina neurosensorial y del espacio subretiniano por las inmunoglobulinas provoca un aumento de la presión osmótica lo cual genera acumulación del fluido intra y subretinal. El "silencio angiográfico" la distingue de otras maculopatías con desprendimientos serosos. La plasmaféresis combinada con quimioterapia constituye la primera línea del tratamiento. Aunque el líquido intrarretinal mejora considerablemente, el subretinal persiste en la mayoría de los ojos. La agudeza visual mejor corregida final muestra una ganancia de 0,3 décimas como promedio después del tratamiento. Con el objetivo de exponer contenido actualizado sobre maculopatía por inmunoganmapatía, se realizó una revisión de las publicaciones más relevantes relacionadas con el tema durante los últimos ocho años.
Immunoganmapathy maculopathy is an unusual macular disease characterized by the presence of intra- and subretinal fluid in association with monoclonal ganmapathies. It may constitute the first manifestation of systemic disease in a considerable number of patients. Infiltration of the neurosensory retina and the subretinal space by immunoglobulins causes an increase in osmotic pressure which leads to accumulation of intra- and subretinal fluid. The "angiographic silence" distinguishes it from other maculopathies with serous detachment. Plasmapheresis combined with chemotherapy is the first line of treatment. Although intraretinal fluid improves considerably, subretinal fluid persists in most eyes. The final best-corrected visual acuity shows a gain of 0.3 tenths on average after treatment. In order to expose updated content on immunoganmopathy maculopathy, a review of the most relevant publications related to the subject during the last eight years was performed.
ABSTRACT
AIM:To observe the changes of macular morphology and microcirculation in myopic maculopathy(MM), and investigate theirs correlation and effects on vision.METHODS: Case-control study. A total of 165 patients(189 eyes)with high myopia and 154 healthy volunteers(154 eyes)from October 2016 to December 2018 were selected. According to the classification of Meta-analysis for pathologic myopia(META-PM), participants were divided into M0 group(category 0, 41 eyes), M1 group(category 1, 53 eyes), M2 group(category 2 and 3, 52 eyes), and myopic choroidal neovascularization(mCNV)group(43 eyes). All participants underwent optical coherence tomography angiography(OCTA)examination. Morphological and microcirculation parameters of retina at different layers were compared between groups. Pearson correlation was used to assess the correlation between morphological and microcirculation parameters. Correlations between vision and other parameters were analyzed using multiple linear regression analysis.RESULTS:Foveal full retinal thickness(FRT)and outer retinal thickness(ORT)were all lower in M0, M1 and M2 groups than those of control group(all P<0.01). Foveal superficial capillary plexus vessel density(SVD)and deep capillary plexus vessel density(DVD)were all lower in M2 and mCNV groups than those of the control group(all P<0.01). Parafoveal FRT and ORT were all lower in M0, M1, M2 and mCNV groups than those of the control group(all P<0.01). Parafoveal inner retinal thickness(IRT), SVD and DVD were all lower in M2 and mCNV groups than those of the control group(all P<0.01). Subfoveal choroidal thickness(SFCT)and choroid capillaries vessel density(CVD)were all lower in M0, M1, M2 and mCNV groups than those of the control group(all P<0.01). Foveal vessel density of retina and choroid were positively correlated with its thickness in patients with MM without CNV(all P<0.05). Multivariate analysis showed that axial length(AL), diffuse or patchy chorioretinal atrophy were influencing foctors of best corrected visual acuity(BCVA; all P<0.01).CONCLUSION:Retinal morphological changes precede microcirculation changes in MM. Most of all, ORT changes precede IRT changes. Foveal vessel density of retina and choroid were positively correlated with its thickness. The main influencing factors of BCVA were AL and types of MM.
ABSTRACT
AIM: To evaluate the efficacy and safety of foveal-sparing internal limiting membrane peeling(FSIP)or complete internal limiting membrane peeling(CMIP)for the treatment of myopic traction maculopathy(MTM)during vitrectomy.METHODS: CNKI, Wanfang, VIP, PubMed, Embase, Cochrane Library, and Web of Science were searched from January 1th 2000 to July 1th 2022, and studies that compared FSIP and CMIP for MTM were collected. The change and recovery rate of best corrected visual acuity(BCVA), incidence of full-thickness macular hole(FTMH), change of central foveal thickness(CFT)and the rate of complete reattachment.RESULTS: A total of 484 eyes from 12 literatures were included, with 203 eyes in the FSIP group and 281 eyes in the CMIP group. The results of Meta-analysis showed that FSIP group were superior to the CMIP group in the mean change of BCVA(SMD=0.52, 95%CI: 0.20～0.85, P=0.002), the improvement rate of BCVA(RR=1.50, 95%CI: 1.22～1.85, P=0.0002)and the incidence of postoperative FTMH(RR=0.23, 95%CI: 0.10～0.54, P=0.0008). There was no statistical difference between the two surgical methods in terms of mean change in CFT(SMD=0.04, 95%CI: -0.19～0.26, P=0.75)and the rate of complete reattachment(RR=1.12, 95%CI: 0.94～1.32, P=0.20).CONCLUSION: FSIP have similar anatomical outcomes compared to CMIP, but FSIP resulted in better visual acuity and lower incidence of postoperative FTMH.
ABSTRACT
Objective:To observe the morphological characteristics of high myopia (HM) paravalvular abnormalities (PVA), and the correlation between different manifestations of PVA and myopic traction maculopathy (MTM) was analyzed.Methods:A cross-sectional clinical study. A total of 42 middle-aged and elderly patients with HM and PVA diagnosed by ophthalmology examination in Department of Ophthalmology, The Second Hospital of Hebei Medical University from June to December 2021 were included in the study. There were 24 eyes in 16 males and 48 eyes in 26 females. Age was (56.71±8.10) years old. Diopter was (-13.05±3.10) D. Axial length (AL) was (28.22±1.04) mm. According to the characteristics of ultra-wide-angle optical coherence tomography images, PVA morphology was divided into paravascular microfolds (PM), paravascular cysts (PC) and paravascular lamellar holes (PLH). MTM was divided into T0-T5 grades, of which MTM≥T3 was defined as severe MTM. The state of vitreoretinal junction was observed and the state of posterior vitreous detachment (PVD) was recorded, which divided into complete PVD and partial PVD. Partial PVD was divided into macular fovea adhesions and paravascular adhesions according to the vitreoretinal adhesions. Posterior scleral staphyloma (PS) was divided into 6 types by ultra-wide-angle fundus photography. Logistic regression model was used to analyze the factors related to MTM.Results:In 72 eyes, PM, PC and PLH were 72 (100.0%, 72/72), 62 (86.1%, 62/72) and 29 (40.3%, 29/72) eyes, respectively. Among them, there were 10 (13.9%, 10/72) eyes with PM alone, 33 (45.8%, 33/72) eyes with PM and PC, and 29 (40.3%, 29/72) eyes with PM, PC and PLH, respectively. There were 42 eyes with partial PVD (58.3%, 42/72), among which the macular fovea and paravascular adhesion were 22 (52.4%, 22/42) and 24 (57.1%, 24/42) eyes, respectively. PS was present in 50 eyes (69.4%, 50/72), among which 27 (54.0%, 27/50), 21 (42.0%, 21/50), 1 (2.0%, 1/50), and 1 (2.0%, 1/50) eyes were types Ⅰ to Ⅳ, respectively. Multivariate logistic regression analysis showed that AL[odds ratio ( OR)=16.139, 95% confidence interval ( CI) 4.062-64.120, P<0.001], PS ( OR=4.212, 95% CI 1.234-14.378, P=0.022), paravascular vitreoretinal adhesion (OR=3.478, 95% CI 11.124, P=0.036) were risk factors for PM, PC and PLH. MTM was present in 58 eyes (80.6%, 58/72), among which T1 was the most common type in 19 eyes (26.4%, 19/72). Univariate logistic regression analysis showed that the occurrence of MTM was significantly correlated to PS ( OR=4.190, 95% CI 1.240-14.157, P=0.021), coexistence of PM, PC and PLH ( OR=11.323, 95% CI 1.389-92.311, P=0.023), and PS were significantly correlated. There was no correlation with PVD ( OR=1.889, 95% CI 0.580-6.150, P=0.291) or PS ( OR=2.778, 1.786; 95% CI 0.700-11.023; 0.445-7.167; P=0.146, 0.413). There was significant difference in the incidence of severe MTM between PM alone, PM combined with PC and coexistence of PM, PC and PLH ( χ2=20.943, P<0.001). Conclusions:PM is the most common and earliest manifestation of PVA in middle-aged and elderly HM patients. AL, PS and paravascular vitreoretinal adhesion are risk factors for PM, PC and PLH. The coexistence of three PVA forms may be a marker of severe MTM.
ABSTRACT
Maculopathy caused by various fundus diseases in the late stage is a common cause of low vision. Medical technology is difficult to reverse the loss of macular function currently, so interventions that help improve the visual system, utilize residual visual function, and improve quality of life deserve attention. Damage to the fovea of the macula does not mean that the entire retinal function is impaired. There may be one or more retinal regions adjacent to the fovea that can serve as a fixation center. It is possible to form stable paracentral fixation, complete functional remodeling of the visual system, and effectively utilize residual visual function by taking appropriate training on these potential paracentral fixation points for most patients. In 2021, a clinical guideline has been published for low vision rehabilitation in China. In order to strengthen the precise management of diseases and develop a standard operating procedure for visual training specifically for patients with low vision due to macular disease, the National Clinical Research Center for Eye Diseases initiated and organized relevant domestic experts, utilizing the latest research experience at home and abroad, and through repeated discussions, this consensus (International Practice Guideline Registration Number: PREPARE-2023CN199) was formed as a reference for ophthalmologists, optometrists and rehabilitation physicians in their clinical research and practice.
ABSTRACT
Objective:To observe the clinical features of eyes in children with methylmalonic acidemia (MMA).Methods:A retrospective clinical case study. From June 2019 to June 2022, 13 children with MMA visited on the Department of Ophthalmology of Henan Children's Hospital were included in the study. The anterior segment and fundus were examined under surface or general anesthesia. Best corrected visual acuity (BCVA) and refraction were performed in 9 cases; fluorescein fundus angiography (FFA) was performed in 3 cases; flash electroretinogram (FERG) was performed in 6 cases; flash visual evoked potential (FVEP) was detected in 6 cases; optical coherence tomography (OCT) was performed in 3 cases.Results:Among the 13 pediatric patients with methylmalonic acidemia, 6 cases were male and 7 cases were female. The average age at first visit was 45 months. All cases suffered from hyperhomocysteinemia; 9 cases were with epilepsy; 2 cases were with infantile spasms; 11 cases were with stunting, 13 cases were with repeated pulmonary infection during growth period; 4 cases were with hydrocephalus; 1 cases was with hypertension and renal insufficiency. Genetic dectection results of 8 cases were recorded, MMACHC:c.609G>A:p.W203* mutation site was found in all cases. One case was accompanied by corneal ulcer. There were 10 cases with nystagmus, 4 cases with macular degeneration, 3 cases with hyperopic refractive error and esotropia. Nine cases underwent BCVA examination, BCVA was light perception-0.6. In OCT, 2 cases of 3 cases showed retinal thinning and photoreceptor cell layer atrophy in the macular area. In FFA, 2 cases of 3 cases showed circular transparent fluorescence in the macular area. Five cases of 6 cases who with FVEP had different degrees of P100 peak time delay and decreased amplitude, and 4 cases of 6 cases with FERG had decrease of a and b wave in light and dark adaptation. Conclusions:The clinical phenotypes of eyes in children with MMA are various and the severity was different; most of them are accompanied by nystagmus, and the fundus lesions are common in the characteristic bovine eye like macular region. Those with macular disease have severe visual impairment.
ABSTRACT
Myopic traction maculopathy (MTM) is a general term for multiple pathological changes such as myopic retinoschisis (MRS), macular hole (MH), and macular detachment (MD) in highly myopic eyes.The new MTM classification methods based on optical coherence tomography, the size and the location of the outer MRS, the relationship of MTM with posterior staphyloma, occurrence of MH and MD deepen the understanding of the disease and effectively assess the condition and prognosis of the disease.The pathogenesis of MTM may be related to the perpendicular and tangential traction produced by vitreoretinal adhesion, internal limiting membrane, and the posterior staphyloma.In the natural course of MTM, the morphology and visual function of most patients with MRS remain stable, and the progression of MRS is related to the severity of schisis and damage to the outer retinal microstructure.Surgical treatment is effective for advanced MTM with significantly impaired visual function.Vitrectomy is the main treatment method for MTM.Macular buckling or combined surgery can be chosen for MRS with MH and/or MD, and posterior scleral reinforcement is also an option for the treatment of MTM with long axial length, posterior staphyloma and poor results of vitrectomy to achieve the goal of relieving internal and external traction and repositioning the retina.The effectiveness of the surgery is also related to a variety of factors.Enzymatic vitreolysis and scleral cross-linking techniques have also provided new ideas for the treatment of MTM.This article summarized the clinical features and treatment strategies of MTM to guide its diagnosis and treatment.
ABSTRACT
Objective@#This small case series demonstrated pars plana vitrectomy and silicone tamponade without internal limiting membrane (ILM) peeling to be a simple, safe, and effective surgical technique for the treatment of myopic traction maculopathy (MTM).@*Methods@#This is a small case series consisting of 3 eyes with MTM. In all eyes, pars plana vitrectomy with silicone oil tamponade was performed by a single vitreoretinal surgeon. Functional and anatomic outcomes are reported.@*Results@#All 3 eyes had improved visual acuity with no noted short-term complications such as iatrogenic macular hole and retinal detachment. Although foveoschisis was only partly anatomically resolved in 2 out of the 3 cases, functional outcome, in terms of visual acuity at last visit, was satisfactory.@*Conclusion@#Vitrectomy with silicone oil tamponade without ILM peeling is a simple, effective, and safe optional surgical technique to treat MTM.
ABSTRACT
AIM:To investigate the changes in the macular microvasculature in eyes with central retinal artery occlusion(CRAO)and paracentral acute middle maculopathy(PAMM).METHODS: Retrospective study. A total of 27 cases(27 eyes)who diagnosed with CRAO-PAMM and 29 patients(29 eyes)diagnosed as CRAO but with no PAMM were hospitalized in our hospital from January 2020 to December 2021. There were 33 normal people(33 eyes)who underwent physical examination in our hospital selected as control group. Optical coherence tomography angiography(OCTA)was used to measure retinal blood flow and thickness parameters in the 3 mm×3 mm area of the macula. The correlation among macular retinal blood flow density, retinal thickness, foveal avascular zone(FAZ)area, FAZ perimeter, acircularity index(AI), flow density in a 300-μm-wide region around the FAZ(FD-300)and lesion area, best corrected visual acuity(BCVA)in the CRAO-PAMM group was analyzed.RESULTS: Among the three groups, there were significant differences in the overall and parafoveal blood flow density of superficial capillary layer(SCP)and deep capillary layer(DCP), foveal thickness, FAZ area, FAZ perimeter, AI and FD-300(all P<0.05). In the CRAO-PAMM group, the lesion area was negatively correlated with DCP overall and parafoveal blood flow density(r=-0.569, P=0.002; r=-0.543, P=0.004), and positively correlated with the parafoveal thickness(r=0.606, P=0.001); BCVA(LogMAR)was negatively correlated with DCP foveal and parafoveal blood flow density(r=-0.433, P=0.024; r=-0.515, P=0.006), and positively correlated with FAZ area, perimeter and lesion area(r=0.484, P=0.011; r=0.531, P=0.004; r=0.417, P=0.030).CONCLUSION:Patients with CRAO and PAMM have lower macular blood flow density, heavier macular edema and poorer visual acuity, and BCVA may be influenced by both lesion area and FAZ area.
ABSTRACT
AIM: To explore the pathogenesis and surgical outcomes of different types of myopic traction maculopathy(MTM)using optical coherence tomography(OCT).METHODS: A total of 193 patients(210 eyes)with MTM were retrospectively included, of which 74 eyes(35.2%)underwent vitrectomy combined with internal limiting membrane(ILM)peeling. The patients were categorized into three groups: foveal detachment(FD), foveoschisis(FS)and lamellar macular hole(LMH). Based on the central foveal thickness(CFT)at baseline(M0), eyes with FD were classified into two subgroups: extensive FD and limited FD. Outcomes included best-corrected visual acuity(BCVA), CFT, posterior staphyloma height(PSH), the presence of epiretinal membrane(ERM)and ILM detachment. Risk factors for BCVA at 6mo after vitrectomy(M6)were analyzed using linear regression.RESULTS: At M0, ERM was highly present in eyes with LMH(rs=0.28, P<0.001). Eyes with FD and FS were characterized by higher incidence of ILM detachment(rs=-0.25, P<0.001). After vitrectomy, CFT and BCVA significantly improved in all eyes(P<0.001). Eyes with extensive FD were characterized by a thicker CFT(rs=0.56, P<0.001), a lower incidence of ILM detachment(rs=-0.25, P=0.034)and a thicker nasal PSH(rs=0.27, P=0.024)than eyes with limited FD. Eyes with extensive FD were associated with a worse BCVA at M0(P=0.013)and M6(P=0.030)than eyes with limited FD. Extensive FD(β=-0.295, P=0.042)and BCVA at M0(β=0.669, P<0.001)were risk factors for a worse BCVA at M6.CONCLUSION: There are several pathogenetic mechanisms in MTM. ILM detachment may exert a dominant role in the development of FD and FS, while ERM may have a role in LMH. Vitrectomy combined with ILM peeling improved functional and anatomical outcomes in MTM patients. Eyes with extensive FD may carry a poor prognosis.

A 44?year?old female with a vision of 10/200 in the right eye had double pits in the temporal segment of the optic disc with serous macular detachment. Spectral?domain optical coherence tomography (SD?OCT) confirmed serous retinal detachment, an outer layer hole, and double optic disc pits. The patient underwent pars plana vitrectomy with modified ILM flap surgery involving fovea?sparing internal limiting membrane peeling (FSIP) technique with inverted ILM flap tucking with gas tamponade. Post surgery, the communications between perineural and intraretinal spaces were obliterated with flaps of ILM covering the pits, with reduced serous macular detachment and BCVA of 20/120. FSIP with inverted internal limiting membrane flap tuck can be an effective technique to manage rare cases of double ODP?M
ABSTRACT
A 41?year?old man presented to the emergency department complaining of decrease of vision in his left eye. Initial examination was consistent with retrobulbar optic neuritis, and an intravenous drip of methylprednisolone was started. On the third day, the fundus examination revealed the appearance of multiple Purtscher?like cotton?wool spots in the posterior pole and nasally to the optic disc, slight retinal whitening around the fovea, and cherry?red spot. The patient reported flu?like symptoms, and he tested positive at PCR (polymerase chain reaction) test for 2019?nCoV (2019 novel coronavirus) infection. Assuming possible 2019?nCoV?related vascular damage, we prescribed low?molecular?weight heparin. The lesions were regressing at follow?up, and we registered a complete visual recovery
ABSTRACT
ABSTRACT The thermal effects of laser cutting machines could damage the macula. A few studies in the literature have described macular injury induced by industrial laser burns. The aim of this study was to report the clinical, visual, and optical coherence tomography findings in a gold refinery worker with laser-induced maculopathy. A 21-year-old male gold refinery worker had vision loss in his right eye after using a laser cutting machine without wearing laser eye protection gear. At the first visit (24 h later), his best-corrected visual acuity was 7/10 in the right eye and 10/10 in the left eye. The anterior segment examination was normal. In fundus examination, focal, round, and yellowish lesion was detected within the fovea. The optical coherence tomography findings were foveal outer retinal disruptions and irregularities extending from the outer plexiform layer to the retina pigment epithelium. After 4 months, the best-corrected visual acuity had improved to 1.0, and the optical coherence tomography findings had resolved.
RESUMO Os efeitos térmicos das máquinas de corte a laser podem danificar a mácula. Poucos estudos na literatura tem descrito a lesão macular por queimadura a laser industrial. Neste estudo, objetivamos relatar os achados clínicos, visuais e de tomografia de coerência óptica em um trabalhador de refinaria de ouro com maculopatia induzida por laser. O trabalhador da refinaria de ouro de 21 anos teve perda de visão no olho direito depois de usar uma máquina de corte a laser sem usar equipamento protetor ocular para laser. Sua acuidade visual melhor corrigida foi de 7/10 no olho direito e 10/10 no olho esquerdo na primeira consulta (24h depois). O exame do segmento anterior estava normal. No exame de fundo de olho, lesões focais, redondas e amareladas foram detectadas dentro da fóvea. Os achados da tomografia de coerência óptica revelaram rupturas na fóvea da retina externa e irregularidades estendendo-se da camada plexiforme externa ao epitélio pigmentar da retina. Após 4 meses, a acuidade visual melhor corrigida melhorou para 1,0 e os achados da tomografia de coerência óptica foram revigorados.
ABSTRACT
Purpose: To report the anatomic and visual outcomes following macular buckling in patients affected by pathological myopia?associated foveoschisis (FS) and macular detachment with or without macular hole (MH). Methods: A retrospective interventional consecutive case series wherein 25 highly myopic eyes (mean axial length 28.46 mm; range, 25–33.8 mm) of 24 patients (16 females and 8 males; mean age 54.1 years; range, 35–74 years) presenting with macular detachment associated with a posterior staphyloma (PS), who underwent macular buckling, were evaluated. Patients with absence or reduction in subretinal fluid by more than 90% during the final follow?up along with inversion of contour of staphyloma were considered to have a successful anatomical outcome and those with improvement or maintenance in visual acuity were considered to have a successful functional outcome. The mean duration of follow?up was 11.2 months. Results: At the time of initial presentation, the mean age of the 24 patients was 54.1 ± 10.28 years. Macular detachment along with FS was present in all cases, whereas full?thickness macular hole?related retinal detachment was present in nine cases. Swept?source optical coherence tomography parameters showed reduction of FS with foveal reattachment in all eyes except one at last visit. Mean axial length decreased from 28.5 mm preoperatively (range 26–33.8 mm) to 26.2 mm (range 24–29.3 mm). The mean best?corrected visual acuity changed from 1.16 log MAR to 1.096 Log MAR (P = 0.165). Visual acuity improved in 10 eyes (40%), remained stable in 11 eyes (44%) and decreased in 4 eyes (16%). Conclusion: Macular buckling is a good surgical technique with encouraging anatomic and visual outcomes in patients with myopic macular detachment associated with PS. Highly selective cases of myopic traction maculopathy can have a viable option of macular buckle surgery in stabilizing the retinal tractional changes, and thereby, vision loss.
ABSTRACT
High myopia is a disease with a high incidence rate and an increasing trend, which could lead to irreversible visual impairment worldwide. Myopia traction maculopathy (MTM), belonging to one of the pathological changes of high myopia, could cause vision damage and even blindness in patients. Recently, a new classification of MTM based on optical coherence tomography can effectively evaluate the condition of patients and is helpful for the diagnosis and treatment of MTM. Moreover, the improvement of internal limiting membrane peeling method and the innovation of macular buckle material provide new ideas for the treatment of MTM based on traditional surgery. New treatment such as vitreal traction release laser surgery, enzymatic vitreolysis and posterior scleral crosslinking have gained increasing attention. By combining these new treatments with artificial intelligence, 3D printing technology and advanced vitrectomy equipment, it is hoped that a safer and more effective treatment for MTM will be found in the future.
