RESUMEN
PURPOSE: To demonstrate the treatment efficacy of intravitreal dexamethasone (DEX) implant in chronic recurrent/persistent central serous chorioretinopathy (CSC). DESIGN: Prospective, non-randomized, open-label study. METHODS: In this study, subjects with chronic CSC without signs of choroidal neovascularization (CNV) received intravitreal DEX implant therapy. The primary outcome measure was the change in visual acuity. Changes in central macular thickness (CMT) and change in subfoveal choroidal thickness (SFCT) on optical coherence tomography (OCT), incidence of recurrent fluid, and safety of DEX implant were secondary outcome measures. Subjects were followed up for a minimum of 3 months after DEX implantation. RESULTS: In total, 20 eyes of 20 subjects (mean age: 47 ± 9 years) with a median disease duration of 23.5 months were enrolled. With a single injection of DEX implant, a reduction in CMT was noted in 90% of eyes. Complete resolution of subretinal and intraretinal fluid was noted in 55% of eyes within 3 months of injection. A significant improvement in vision (mean Log MAR visual acuity 0.66 ± 0.49 vs. 0.54 ± 0.45; P = 0.020), mean CMT (338 ± 110 microns to 238 ± 73 microns; P < 0.001) and SFCT (514 ± 95 microns to 445 ± 111 microns; P < 0.001) was noted over 3 months. Recurrent fluid was noted in 50% of eyes after a mean follow-up duration of 7 ± 4 months. Elevated intraocular pressure, managed by topical therapy, was noted in six eyes. CONCLUSION: The consistent improvement in visual acuity, fluid resolution, and reduction in choroidal thickness suggests a possible role for DEX implants in managing chronic CSC. A larger randomized trial is warranted.
RESUMEN
PURPOSE: To describe a potential biomarker termed as inner choroidal fibrosis in cases of chronic central serous chorioretinopathy (CSCR) presenting to a tertiary referral center. DESIGN: Observational case series. METHODS: Five eyes of 4 patients with CSCR were noted to have a gray-white subretinal lesion in the macula, which was analyzed with multimodal imaging. RESULTS: The lesions were hypofluorescent on autofluorescence, fundus fluorescein angiography, and indocyanine angiography. In all cases, a characteristic heterogeneous, hyperreflective lesion in the inner choroid was seen on optical coherence tomography (OCT), corresponding to the white subretinal lesions. The lesion was distinct from the adjacent choroid, with greater reflectivity and greater thickness than the adjacent compressed choroidal vasculature. The dilated outer pachyvessels were pushed outward or sideways in all cases. On OCT-angiography, the corresponding lesion showed flow void areas. We have termed this zone of inner choroidal hyperreflectivity "inner choroidal fibrosis." Upon analyzing the clinical course, 3 of the patients had a history of choroidal neovascularization. The contralateral eye in 2 of these 3 patients also developed choroidal neovascularization. Three of the eyes had an overlying focal choroidal excavation. CONCLUSIONS: We report a potential biomarker of CSCR termed "inner choroidal fibrosis" in 4 cases of chronic CSCR. It can best be identified on enhanced depth or swept source OCT as a region of heterogeneous hyperreflectivity in the inner choroid. This fibrosis could be regarded as a degenerative process secondary to more severe disease in the past.

PURPOSE: To study intravitreal brolucizumab in the management of persistent macular fluid in chronic central serous chorioretinopathy (CSCR) without choroidal neovascular membrane (CNVM). METHODS: Retrospective case series which included eyes with chronic CSCR with persistent macular fluid for ≥ 3 months without CNVM. Intravitreal brolucizumab was administered in all eyes. Primary outcome measure was the resolution of intraretinal (IRF) and/or subretinal fluid (SRF) on OCT. RESULTS: Five eyes (four patients) with chronic CSCR were included. All eyes showed complete resolution of SRF 1 month following injection. Minimal residual IRF was present in two eyes. Best corrected visual acuity (BCVA) was stable in three eyes, and two eyes showed improvement. Central macular thickness (CMT) and subfoveal choroidal thickness (SFCT) showed reduction. CONCLUSION: Intravitreal brolucizumab is effective in the rapid reduction of persistent macular fluid in chronic CSCR without CNVM. Long-term follow-up data are required to study recurrence and adverse effect profile.
RESUMEN
Purpose: To report a big data analysis of risk and protective factors in patients with AMD, as well as report on the age-adjusted prevalence in a geriatric Indian cohort in a hospital setting. Methods: This retrospective, observational study of all patients older than 60 years of age. Multiple logistic regression was performed for the binary outcome and the presence of AMD. Variables analyzed include age, gender, socioeconomic status, occupation, urban-rural-metropolitan distribution, self-reported history of diabetes mellitus (DM), hypertension (HTN), or coronary artery disease (CAD), ocular comorbidities, history of cataract surgery, and presenting VA. Odds ratios (OR) and 99% confidence intervals were calculated. Results: Of the 608,171 patients over the age of 60 years who attended our clinics, 1.68% of subjects had a diagnosis of AMD (N = 10,217). Less than half (4,621 of 10,217 with AMD) of them were diagnosed to have dry AMD. Cataract, glaucoma, and diabetic retinopathy were associated with lower risk of AMD. Cataract surgery was associated with the higher risk of AMD (OR = 1.20; 99% CI 1.13-1.29). Smoking was not associated with AMD. Conclusion: Big data analysis from a hospital setting shows that the prevalence of AMD above the age of 60 years is low. More patients with wet AMD present for treatment compared to dry AMD. Smoking was not associated with AMD in the Indian population. Cataract surgery was associated with higher prevalence of AMD.

A woman in her 60s presented with vision blur in both eyes, a year post-radiotherapy for oral cancer. The best corrected visual acuity was 20/40 in both eyes. Posterior segment examination was remarkable for a unilateral intervortex venous anastomosis in choroid in her right eye, on the side of her face that had received radiation. Ultra-wide field indocyanine green angiography complimented the clinical findings. We discuss the ramifications of detection of this entity and suggest non-invasive methods of detection.

Purpose: To describe clinical and imaging characteristics of the outer retinal folds (ORF) in cases of retinitis, retinochoroiditis, and chorioretinitis. Methods: Retrospective review of retinitis cases with presence of ORFs either at presentation or during follow up. Results: ORFs were seen adjacent to retinitis lesions in 16 eyes of 14 cases (retinitis post-febrile illness n = 10, toxoplasma retinochoroiditis n = 2, fungal chorioretinitis n = 2) either at presentation (n = 2) or during follow up (n = 14). Optical coherence tomography (OCT) appearance was outer retinal vertical stout lesions involving ellipsoid, external limiting membrane, and outer nuclear layer. All the cases had a presence of past or concurrent subretinal fluid and/or subretinal hyperreflective material when ORF was seen. ORF resolved with variable outer retinal atrophy over a mean period of 2.86 months. Conclusion: ORF is observed in cases of retinitis with subretinal fluid either at presentation or during resolution. It is not specific to any etiological disease. Differentiation of this sign from vertical outer retinal stripes in viral retinitis on OCT is important to avoid misinterpretation.

A systematic review and meta-analysis were conducted to estimate the prevalence of diabetic retinopathy (DR) in India's urban and rural areas. Medline, Scopus, and ScienceDirect databases were searched for population-based studies published in English between January 1990 and April 2021, wherein the prevalence of DR among Indian residents with type 2 diabetes mellitus (DM) was reported. A random-effects model was used to estimate the overall, rural, and urban prevalence. Data from 10 eligible studies were aggregated for meta-analysis. The prevalence of DR was 17.44% (95% confidence interval [CI], 14.33-20.55) in urban and 14.00% (95% CI: 9.13-18.86) in rural population (P = 0.24). The overall DR prevalence was 16.10% (95% CI: 13.16-24.32), and the population prevalence was 1.63% [95% CI: 0.94-2.32]. Prevalence of DR in people with diabetes was lower in the age group of 40-49 years [13.57% (95% CI: 7.16-19.98)] than in the age group of 50-59 years [16.72% (95% CI: 12.80-20.64)] and the age group of 60 years and above [16.55% (95% CI: 12.09-21.00)]. Variability in studies was high: urban (I2 = 88.90%); rural (I2 = 92.14%). Pooled estimates indicate a narrow difference in DR prevalence among people with diabetes in rural and urban India. The fast urbanization and increasing diabetes prevalence in rural areas underscore the need for providing equitable eye care at the bottom of the health pyramid.

PURPOSE: To correlate optical coherence tomography (OCT)-based morphological patterns of diabetic macular edema (DME), biomarkers and grade of diabetic retinopathy (DR) in patients with various stages of chronic kidney disease (CKD) secondary to diabetes. DESIGN: Multicentric retrospective cross-sectional study was conducted at seven centers across India. METHODS: Data from medical records of patients with DME and CKD were entered in a common excel sheet across all seven centers. Staging of CKD was based on estimated glomerular filtration rate (eGFR). RESULTS: The most common morphological pattern of DME was cystoid pattern (42%) followed by the mixed pattern (31%). The proportion of different morphological patterns did not significantly vary across various CKD stages (p = 0.836). The presence of external limiting membrane-ellipsoid zone (ELM-EZ) defects (p < 0.001) and foveal sub-field thickness (p = 0.024) showed a direct correlation with the stage of CKD which was statistically significant. The presence of hyperreflective dots (HRD) and disorganization of inner retinal layers (DRIL) showed no significant correlation with the stage of CKD. Sight threatening DR was found to increase from 70% in CKD stage 3 to 82% in stages 4 and 5 of CKD, and this was statistically significant (p = 0.03). CONCLUSION: Cystoid morphological pattern followed by mixed type was the most common pattern of DME on OCT found in patients suffering from stage 3 to 5 of CKD. However, the morphological patterns of DME did not significantly vary across various CKD stages. ELM-EZ defects may be considered as an important OCT biomarker for advanced stage of CKD.

PURPOSE: To describe clinical and multimodal imaging characteristics of punctate inner retinal toxoplasmosis (PIRT) as an atypical presentation of ocular toxoplasmosis (OT). METHODS: Retrospective review of OT cases with PIRT lesions and review of the literature. We describe five cases (6 eyes). RESULTS: PIRT lesions were seen adjacent to active/healed toxoplasma retinochoroiditis. The appearance of PIRT was creamy yellowish-white, inner retinal, punctate, and sub-centimetric lesions. The depth of these lesions on optical coherence tomography was till the outer plexiform layer. Co-existing punctate outer retinal toxoplasmosis (PORT) was found in three eyes and recurrent retinochoroiditis in three. The fate of PIRT was resolution with minimal retinal thinning or progression to a full-thickness retinochoroiditis. CONCLUSION: PIRT was noted in association with typical toxoplasma retinochoroiditis and PORT lesions, and had equal chances of resolution or progression to full-thickness lesions.

PURPOSE: To study the efficacy and safety of a modified trans-scleral intraocular lens (IOL) fixation technique in aphakic eyes when performed by ophthalmologists in training. METHODS: The study was conducted in an institutional setting that included 43 surgeries performed by surgeons training in small incision cataract surgeries. The data were analyzed for stability and position of IOL, refractive changes, best-corrected vision, and associated complications. RESULTS: Mean age of the subjects was 53.8 ± 18.5yrs (range 6-81yrs). Surgical aphakia (58.14%) was the most common cause. The corrected distance visual acuity improved significantly at six weeks (p = 0.0003). The mean residual spectacle correction was +0.74 ± 1.2D spherical equivalent (cylinder -1.6±1.5D at 84 ± 50°) at the 6th-month follow-up (24.35 ± 6.71wks). Lens tilt on ultrasound biomicroscopy (kappa 0.762; p < 0.001) and the IOL centration (kappa 0.411; p = 0.001), assessed by two independent masked observers, were satisfactory at the 6th-month visit. Transient postoperative vitreous hemorrhage was the most common complication (46.5%). Cellular deposits on the IOL surface (18.6%), cystoid macular edema (11.6%), subconjunctival haptic exposure (4.66%), and haptic slippage (2.33%) were the other complications. CONCLUSION: This method of trans-scleral IOL fixation is an effective rescue procedure for eyes with deficient capsular support when ophthalmologists perform in training.
RESUMEN
PURPOSE: To study the prevalence of systemic conditions in older adults, either self-reported or discovered during routine eye examinations, at multitier eye-care facilities over the past decade, and to explore their association with vision and common ocular disorders, including cataract, glaucoma, and retinopathy. METHODS: Retrospective review of a large data set compiled from the electronic medical records of patients older than 60 years who presented to an eye facility of a multitier ophthalmology network located in 200 different geographical locations that included urban and rural eye-care centers spread across four states in India over a 10-year period. RESULTS: 618,096 subjects aged 60 or older were identified as visiting an eye facility over the 10-year study period. The mean age of the study individuals was 67·28 (±6·14) years. A majority of older adults (66·96%) reported being free of systemic illnesses. Patients from lower socioeconomic status had a lower prevalence of chronic systemic disease, but the presenting vision was poorer. Hypertension (21·62%) and diabetes (18·77%) were the most commonly reported chronic conditions in patients who had concomitant systemic illness with visual concerns. CONCLUSION: The prevalence of chronic systemic illnesses in older adults presenting to multitier eye-care facilities is relatively low, except in those with diabetic retinopathy. These observations suggest a need to include active screening for common chronic diseases in standalone eye-care facilities to achieve a more accurate assessment of chronic disease burden in the older population.

PURPOSE: To assess the treatment benefit of eyes with diabetic macular edema (DME) in vitrectomized eyes for tractional complications of proliferative diabetic retinopathy (PDR). METHODS: In a retrospective multicentre observational study in India, the clinical outcomes of eyes with center-involving DME in vitrectomized eyes for tractional complications of PDR in people with type 2 diabetes with at least 12 months follow-up data were assessed. The DME status and visual acuity outcomes were compared between those who received treatment versus those observed. RESULTS: In the 10-year study period, 45 eyes of 44 patients from 5 tertiary centers in India met the inclusion criteria. Center-involving DME was documented after a mean of 7 ± 7 months following pars plan vitrectomy (PPV) for tractional complications of PDR. More than half of the (n = 25) eyes were immediately treated for DME, and treatment was deferred for the rest. At one year, there was a statistically significant reduction in mean central subfield thickness in treated (467.9 ± 124.8 µm to 367.8 ± 143.7 µm; p < 0.001) as well as observed (405.2 ± 132.6 µm to 325.6 ± 149 µm; p < 0.001) eyes, and the change was comparable (p = 0.574). The change in vision was also comparable (0.12 ± 0.31 and 0.22 ± 0.54 Log MAR in the treated and observed group, respectively; p = 0.443). CONCLUSION: Treatment for pre-existing or new-onset DME after PPV for tractional complications of PDR may be deferred for up to one year because the DME may resolve spontaneously with time.

Purpose: To analyse clinico-microbiological profile, antimicrobial susceptibilities, and visual prognostic factors in post-traumatic endophthalmitis (PTE).Methods: Retrospective clinico-microbiological data analysis for five years (2014-18). Prognostic factors for visual outcomes were analysed by multivariate logistic regression analysis.Results: Four hundred and eighteen patients with clinically diagnosed PTE were analysed. Culture positivity was found in 46.7% samples (44.5% vitreous, 83.3% non-vitreous). Pathogens isolated were Gram positive cocci (GPC, 49.3%, good susceptibility to vancomycin/cefazolin), Gram negative bacilli (GNB, 28.1%, <90% susceptibility to all antibiotics and 25.8% multidrug resistance), Gram positive bacilli (13.1%) and fungi (9.5%). Poor visual prognosis was associated with culture positivity, fungal or polymicrobial PTE, poor view of fundus and presence of membranes on ultrasound scans.Conclusion: GPC and GNB are the predominant pathogens in PTE, with GNB most commonly multidrug resistant. Culture positivity, polymicrobial and fungal PTE, poor view of fundus and vitreous membranes are markers of poor visual outcome.

Purpose: To describe the course of posterior subhyaloid precipitates (PSPs) accompanying active retinitis. Methods: Retrospective study of three retinitis cases associated with PSPs and literature review. Results: Cases 1 and 2 were Toxoplasma retinochoroiditis. Case 3 had bilateral retinitis post-febrile illness. PSPs were yellowish-white spherical lesions seen in the presence of partial posterior hyaloid detachment (PVD) in the retro-hyaloid space lining the inferior PVD margin. In all 3 cases, PSPs resolved during treatment for primary disease. Resolution of PSPs preceded resolution of retinitis. Literature review revealed similar lesions in CMV retinitis and syphilis in addition to Toxoplasma retinochoroiditis. Conclusion: PSPs were seen in the presence of active retinitis and partial PVD when inflammatory aggregates gravitate inferiorly in the subhyaloid space. They were observed during active retinitis and their resolution preceded the resolution of retinitis, thus providing a potential marker for disease resolution.

PURPOSE: To compare the disease characteristics and treatment outcomes of patients with neovascular glaucoma (NVG) presenting with visual acuity (VA) 6/60 or better in two different health systems. METHODS: Retrospective chart review of consecutive patients with NVG who presented between January 2016 to January 2018 in 5 tertiary-centres in India and one eye-specialist centre in London (UK) was performed. The baseline characteristics, treatment provisions, and visual outcomes in the India and UK cohorts were compared. RESULTS: At presentation, 18% (83 of 451) and 22% (59 of 270) of patients with NVG had VA 6/60 or better in India and the UK cohorts, respectively. The aetiologies of NVG were similar with proliferative diabetic retinopathy being the most common cause (60.9%, India; 64.4%, UK; p = 0.38). Previous panretinal photocoagulation was more prevalent in the UK cohort compared to the India cohort (94.9% versus 66.3%, respectively; p < 0.001). The mean number of intravitreal anti-VEGF injections per eye was higher in the Indian cohort (1.65 ± 0.97 versus 1.14 ± 1.02 injections; p < 0.001). The number of eyes with closed angles (36.9% India versus 30.5% UK; p = 0.45) and the number of eyes needing glaucoma interventions (52.1% India; 62.7% UK; p = 0.82) were similar in two cohorts. Among glaucoma surgeries, trabeculectomies were more commonly performed in the Indian cohort (23 vs 4; p < 0.001),while glaucoma drainage device surgeries were more prevalent in the UK cohort (18 vs 4 p < 0.001). After a median follow-up of 21 months (IQR 8.4-34.8 India; 24-36 months UK), favourable visual outcomes (vision stable or improved) were similar in both health systems (52.5% in the Indian cohort vs 43.4% in the UK cohort; p = 0.28). On multivariate regression analysis, the need for trans-scleral cyclophotocoagulation was associated with worse visual outcomes in both cohorts. CONCLUSIONS: The causes and clinical profile of neovascular glaucoma with presenting visual acuity 6/60 or better in India and the UK were similar. Only up to 50% of eyes achieved favourable visual outcomes with current management protocols in both health systems.

PURPOSE: To study the initial presenting symptoms of Takayasu arteritis in unsuspecting patients. METHODS: The underlying systemic condition was suspected in five subjects at a tertiary eye care center based on their ocular features. Similar reports in the literature were collated and analyzed for the common presenting features of undiagnosed Takayasu arteritis. RESULTS: The most common presenting ophthalmic symptoms were vision loss (86.8%), ocular pain (21.1%), eye redness (18.4%), and photophobia (5.3%). There were no reports of glaucoma at presentation. Pupillary abnormalities (42.1%), microaneurysms in retinal mid-periphery (42.1%) and venous engorgement (28.9%) were the most common presenting signs. Despite systemic symptoms such as headache, dizziness, fatigue, weakness, arm claudication, fever, anorexia, weight loss, and syncope in 76.3% of cases, the patients in this series had never sought medical care before developing ocular symptoms. CONCLUSION: Takayasu arteritis may remain latent until the ophthalmic complications compel the patient to seek medical attention. Hence, ophthalmologists need to be aware of the seemingly innocuous presentations of the disease.

Purpose: The purpose of this study is to study single surgery reattachment rate, refractive shift, surgical time, cost, and complications of pneumoretinopexy (PR) compared to scleral buckling (SB) in rhegmatogenous retinal detachments (RRDs) with superior breaks. Methods: Data of RRD with superior breaks, from 2013 through 2016, treated either with PR or SB surgery at a tertiary eye-care center were retrospectively reviewed. Treatment outcomes, procedural costs, refractive shift, surgical time, and complications, namely, cataract and glaucoma, were analyzed. Results: Thirty-two cases treated by PR (n = 15) and SB surgery (n = 17) fulfilled the selection criteria. Macula off RRD (91%) was the commonest presentation. Baseline parameters like duration of vision loss, presenting vision, and ocular characteristics were comparable. Single surgery retinal reattachment (66.7% PR vs. 76.5% SB) was analogous (P = 0.698). Retinal reattachment with secondary intervention was achieved in all cases at the last follow-up. Average vision gain in logMAR of 0.8 in PR and 0.6 in SB was not significantly different (P = 0.645) between the two groups, with SB group having a 1.9 Dioptre myopic shift and PR group none. Surgical time was shorter in PR versus SB at 15 versus 85 min and surgical cost (including additional surgery) was 50% less in PR. Complications like cataract progression (P > 0.99) and glaucoma (P = 0.71) were analogous among the groups. Horse-shoe tears were associated with failed primary surgery in 60% of PR and 75% of SB procedures. Conclusion: In RRDs secondary to superior breaks, PR proved to be faster, more economical, and less tissue manipulative than scleral buckle surgery, with equivalent efficacy and safety profile.

PURPOSE: To report the clinical course of ophthalmia nodosa with a retained lenticular seta misdiagnosed and treated as non-infectious posterior uveitis for 7 consecutive years. METHODS: Meticulous clinical examination led to discovery of the caterpillar seta embedded in the crystalline lens and the intravitreal setae. RESULTS: Lens-sparing pars plana vitrectomy and removal of free-floating vitreal seta resulted in complete resolution of vitritis and uveitis. CONCLUSION: Embedded seta within a clear lens may remain sequestered, and may be left untouched under close observation, precluding a clear lens extraction in such patients.

INTRODUCTION: To report the 10-year rate of vitrectomies and the associated factors in people with proliferative diabetic retinopathy (PDR) from a multicentric cohort of people with diabetes mellitus. METHODS: Ten centres in India with established vitreoretinal (VR) services for over 10 years were invited to provide long-term data on PDR. People with Type 1 or 2 diabetes with a clinical diagnosis of active PDR in 1 or both eyes were included. Baseline data collected included age, sex, duration of diabetes, source of referral and best-corrected visual acuity, and diabetic retinopathy status in both eyes. Available follow-up data included the numbers of panretinal photocoagulation (PRP) sessions, cataract surgery, treatment of diabetic macular oedema, use of anti-vascular endothelial growth factor (VEGF) therapy, vitrectomy with or without retinal surgeries over 10 years. RESULTS: Over 10 years, 89% needed supplemental PRP after initial complete PRP. One-third required retinal surgery, 16% needed intravitreal injection. Men (74.5%) had significant higher risk for vitreous (VR) surgery. Of the group with low-risk PDR, 56.8% did not require VR surgery, p < 0.001. Of the patients who underwent cataract surgery and had intravitreal anti-VEGF injections, 78.5 and 28.2% needed subsequent vitreous (VR) surgery, p = 0.006 and <0.0001, respectively. Independent predictors of need for vitreoretinal surgery included those who underwent cataract surgery and those with poor baseline visual acuity (logMAR). Eyes at lower risk for VR surgery included the eyes previously treated with PRP and low-risk PDR at baseline. CONCLUSION: Despite initial "complete" PRP, one-third of our study cohort needed vitrectomies over 10 years, highlighting that these patients require regular follow-up for a long period of time.
