RESUMO
BACKGROUND: In this report, we describe a case of proliferative diabetic retinopathy that developed into exudative changes confusing with central serous chorioretinopathy (CSCR) following extensive endolaser pan retinal photocoagulation. CASE DESCRIPTION: A 49-year-old male patient with diabetic retinopathy in both eyes presented with vitreous hemorrhage and 6/60 visual acuity in his left eye. Optical coherence tomography (OCT) scans at presentation revealed serous PEDs in both eyes. On day 10 after vitreoretinal surgery and complete peripheral endolaser PRP for the left eye, there was serous retinal detachment (SRD) and an increase in PED heights, mimicking CSCR. No additional treatment was considered. At the three-week post-operative visit, OCT scans revealed that the SRD had resolved and the PED heights had decreased without rupture. At the final follow-up visit, 12 weeks after surgery, the SRD had not recurred, and the PEDs had stabilized. Despite no additional ocular therapy for the right eye, the serous PED height had decreased. The choroidal thickness (CT) at the fovea at various points during the follow-up visits revealed a reduction in both eyes. CONCLUSION: This case demonstrated the course of SRD, PED, and CT following extensive PRP. These changes may be associated with intraocular VEGF changes. In the presence of SRD and serous PED, the PED morphology may help differentiate the condition from CSCR. Although caution should be exercised when performing PRP during surgery or as an outpatient procedure, the SRD usually resolves without problem.

PURPOSE: To describe the evolution of posterior staphyloma-induced serous maculopathy (PSISM) in a patient with myopic tilted disc syndrome and its treatment with subthreshold micro pulse laser (SMPL) therapy. CASE DESCRIPTION: A 38-year-old male, diagnosed previously with classical features of myopic tilted disc syndrome presented to the retina clinic after 5 years from the initial presentation with blurred vision in the right eye for 6 months, visual acuity of 6/15 and findings of serous macular detachment (SMD) and subretinal precipitates at the upper margin of the posterior staphyloma. Retinal imaging ruled out other causes of SMD such as chronic central serous chorioretinopathy, myopic macular neovascularisation and dome shaped macula. A diagnosis of PSISM was confirmed. The left eye fundus and macula was normal. RESULTS: Confluent SMPL burns were applied across the SMD. The serous maculopathy resolved over a period of 2 months and visual acuity improved to 6/9. No recurrence of SMD was noted even after 14 months post SMPL. CONCLUSION: PSISM develops gradually in eyes with myopic titled disc syndrome. SMPL is a viable therapeutic option in the management of PSISM and should be considered early in the treatment options.
RESUMO
PURPOSE: To describe a case of acquired glaucomatous optic disc pit-related maculopathy successfully treated with glaucoma filtering surgery alone. CASE DESCRIPTION: A 67-year-old male was diagnosed with advanced primary open angle glaucoma in both eyes, with a cup: disc ratio of 0.85 in the right eye and 0.95 in the left eye. Visual acuity at presentation was 20/60, and intraocular pressure was 14â mm Hg in the left eye. The fundus of the left eye revealed a serous macular retinal detachment due to an acquired optic disc pit. RESULTS: The left eye of the patient underwent combined cataract and glaucoma filtering surgery. The serous macular detachment resolved completely 15 months after surgery, with a documented visual acuity of 20/40 and intraocular pressure of 10â mm Hg without the use of additional antiglaucoma medications. There was no recurrence of serous macular detachment even after the two-year follow-up visit. CONCLUSION: This case demonstrates that controlling intraocular pressure alone resulted in complete resolution of serous macular detachment in acquired optic disc pit maculopathy without the need for pars plana vitrectomy.

PURPOSE: To study cases diagnosed of myelinated retinal nerve fibres (MRNF) continuous with the optic disc and describe the plausible pathogenic mechanism for the ocular features in Straatsma syndrome. METHODS: This retrospective observational study includes clinically diagnosed MRNF cases. MRNF, myopia, and amblyopia defined Straatsma syndrome. MRNF were classified into three types based on location: type 1 in the superior retina, type 2 in the superior and inferior retina, and type 3 in the inferior retina. MRNF size was measured on Optomap® (Optos, Daytona, UK) images and posterior staphyloma location was noted. Demographics and best-corrected refractive error in logMAR units was recorded. Descriptive statistics and Spearman's corelation test were used to analyse MRNF size's relationship to refractive error and logMAR visual acuity. RESULTS: The study included a total of 19 MRNF eyes from 18 patients. Seventeen (89%) eyes had Straatsma syndrome. Median age was 23.50 [range: 4-75] years. One (6%) patient exhibited bilateral presentation. The median logMAR visual acuity was 0.4 log units (interquartile range: 0.18-1.20) and mean refractive error was -7.21 ± 5.32. Type 2 MRNF (n = 14,74%) was the commonest. Average MRNF size was 34.37 ± 40.73â sq.mm. Posterior staphyloma was noted in 17 eyes, all in close MRNF association. Significant positive corelation was noted between logMAR visual acuity and MRNF size (r = 0.5, p = 0.028). CONCLUSION: Large size MRNF corelated with poor visual acuity in the study. The paper explains the possible pathogenetic mechanisms for the ocular findings seen in MRNF.
RESUMO
PURPOSE: The purpose of this study is to describe and compare the demographic, ocular, and imaging characteristics of a cohort of patients with congenital and acquired optic disc pit maculopathy (ODPM). METHODS: This retrospective case series included patients diagnosed with ODPM between June 2017 and April 2023. These patients' baseline demographics, ocular characteristics, and optical coherence tomography (OCT) imaging characteristics and follow up changes were analyzed. RESULTS: A total of 14 eyes with ODPM were identified (9 congenital and 5 acquired). Eyes with congenital ODP developed maculopathy at a younger age, presented commonly with visual symptoms, and exhibited an obvious pit at the temporal foveal margin as well as a high cup: disc ratio (p < 0.05). Primary open-angle glaucoma was identified in all five eyes with acquired ODPM. On OCT, eyes with acquired ODPM lacked the characteristic nerve fibre layer schisis, outer retinal layer hole, and foveal serous macular detachment (p < 0.05) unlike congenital ODPM. At the final follow-up visit, two cases from the congenital ODPM group and one case from the acquired ODPM group displayed complete resolution of maculopathy. The two cases of congenital ODPM were treated with pars plana vitrectomy and laser barrage to the optic disc margin, while the solitary case of acquired ODPM was treated with trabeculectomy surgery alone. CONCLUSION: Clinical examination and baseline OCT imaging reveal distinct differences between congenital and acquired ODPM eyes. These characteristics may help with accurate diagnosis and treatment planning for these two distinct clinical entities.
RESUMO
PURPOSE: Hallmark of Diabetic Retinopathy (DR) is blood-retinal barrier alteration. Vascular endothelial growth factor (VEGF) and inflammation are involved in the pathogenesis of DR. Anti-VEGFs and lasers are effective in treating DR but have numerous drawbacks, hence the need to develop alternative therapies that may delay the onset or progression of DR. METHODS: Fifteen patients were recruited in each group; the study group was on immunosuppressants for some other coexisting disease and the control group was not on them. Each subject underwent detailed history, ophthalmic examination, and glycosylated hemoglobin (HbA1c) and renal function tests at the time of recruitment and the end of one year. Primary outcome measure was to compare the progression of DR in diabetics on immunosuppressant versus those not on it. RESULTS: Median age in the study and control group was 57 years and 60 years, respectively (P = 0.6). Median duration of diabetes was 11 and 12 years in the study and control group, respectively (P = 0.7). HbA1c for the study and control group for first visit was 7.6% and 8.0%, respectively (P = 0.26) and for second visit was 7.5% and 8.1%, respectively (P = 0.11). Hypertensives in the study and control groups were 9 and 4, respectively (P = 0.065); renal disease in the study and control groups was 4 and 2, respectively (P = 0.361). The control group showed 33.3% progression of DR, and no progression was seen in the study group (P = 0.014). CONCLUSION: Immunosuppressants seemed to delay the onset and progression of DR in the earlier stages.
