Inner Choroidal Fibrosis: An Optical Coherence Tomography Biomarker of Severity in Chronic Central Serous Chorioretinopathy.

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.

Antibiotic susceptibility in Endophthalmitis Management Study and intravitreal antibiotic practice trend in India-EMS Report #5.

AIM: Analyze antibiotic susceptibility in the Endophthalmitis Management Study (EMS) and compare it with the current intravitreal antibiotic practice trend of members of the Vitreoretinal Society of India (VRSI) practicing in India. METHODS: The microbiology work-up of undiluted vitreous included microscopy, culture-susceptibility, polymerase chain reaction (PCR), and next-generation sequencing (NGS). VRSI members were invited to the survey. The EMS conventional culture-susceptibility (PCR and NGS excluded) results were compared vis-a-vis gram-positive cocci (GPC), gram-negative bacilli (GNB), and less commonly used antibiotics with the current recommended intravitreal antibiotics. p < 0.05 was considered significant. RESULTS: Culture and positivity (culture + PCR/NGS) positivity was 28.8% and 56.1%, respectively. GPC was most susceptible to cefazolin, linezolid, and vancomycin; GNB was most susceptible to amikacin, ceftazidime, colistin, and imipenem. There was no susceptibility difference between cefazolin and vancomycin (p = 0.999) and between ceftazidime and imipenem (p = 1.0). Colistin was superior to ceftazidime (p = 0.047) against GNB. The GNB resistant to amikacin (n = 14) were equally susceptible to ceftazidime and colistin; resistant to ceftazidime (n = 16) were susceptible to colistin; and resistant to colistin (n = 7) were susceptible to ceftazidime. The preference of VRSI members (n = 231) practicing in India was a vancomycin-ceftazidime combination (82%), vancomycin for GPC (94%), ceftazidime for GNB (61%), and voriconazole for fungi (74%). CONCLUSION: In EMS, GPC had good susceptibility to vancomycin; GNB had good susceptibility to ceftazidime and colistin. Given the lower resistance of colistin, a vancomycin-colistin combination could be an alternative empiric treatment in post-cataract endophthalmitis in India.

Intravitreal Brolucizumab for Chronic Central Serous Chorioretinopathy without Choroidal Neovascular Membrane - a Pilot Study.

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.

Natural course of non-center-involving diabetic macular edema progression in patients under initial observation.

PURPOSE: We aim to report the natural course of non-center involving diabetic macular edema (NCIDME) progression to center involving diabetic macular edema (CIDME) and associated risk factors. METHODS: This is a multicenter retrospective comparative study. Data was collected from electronic medical records from 8 centers in India covering. We included patients with type 2 diabetes above 18 years of age with treatment-naïve NCIDME on OCT and best-corrected visual acuity at baseline of 6/12 or better who were under observation for NCIDME and had 2 years follow-up data. RESULTS: Out of 72 patients with NCIDME, 26.38% patients progressed to CI DME by 2 years, and the visit wise proportion was 11.11% at 6 months, 7% at 1st year and 8.3% at 2 years. The change in CST was statistically significant at 2 years in patients who developed CIDME, the mean difference was 137.73 ± 48.56 microns p = 0.045. Duration of diabetes mellitus > 10 years was the only risk factor for conversion to CIDME. CONCLUSION: A quarter of eyes with NCIDME developed CIDME and 15% progressed from NPDR to PDR by 2 years, highlighting the disease burden in these patients with NCIDME.

Evaluating the utility of inflammation score in post-cataract surgery endophthalmitis. Results from a prospective study in India. EMS Report #4.

PURPOSE: To investigate if inflammation score (IS), calculated from the cornea, anterior chamber, iris, and vitreous, indicates endophthalmitis severity. METHODS: In a prospective study, consecutive adults with a clinical diagnosis of post-cataract endophthalmitis within 6 weeks of surgery were recruited. Patients were allocated to IS-based primary treatment (IS < 10: intravitreal injection and IS ≥ 10: vitrectomy) and randomized to two intravitreal antibiotics combinations (vancomycin + ceftazidime and vancomycin + imipenem). Undiluted vitreous microbiology work-up included culture susceptibility, polymerase chain reaction, Sanger sequencing, and targeted next-generation sequencing. RESULTS: The average age of 175 people was 63.4 ± 10.7 years and included 52.6% small incision cataract surgery and 47.4% phacoemulsification surgery. Severe endophthalmitis (IS ≥ 20), diagnosed in 27.4% of people, had a shorter time to symptoms (average 5.4 vs 8.7 days; P = 0.018), poorer presenting vision (all ≤ hand motion), higher culture positivity (50% vs 30.7%; P = 0.032), and higher Gram-negative bacterial infection (70.8% vs 46.2%; P = 0.042). For IS ≥ 20 discriminant and Gram-negative infection, Spearman's coefficient was 0.7 [P < 0.0001, 95% confidence interval (CI) 0.59-0.82], with an area under the receiver operating characteristic curve of 0.9 (95% CI 0.85-0.94, P < 0.0001), a Youden index J of 0.74, a sensitivity of 87.2%, and a specificity of 87.5%. The final vision of >20/400 and >20/100 was regained in 50.2% and 29.1% of people, respectively. The susceptibility of common Gram-positive cocci and Gram-negative bacilli was the highest for vancomycin (95.0%) and colistin (88.6%), respectively. NGS detected polymicrobial infection in 88.5% of culture-negative endophthalmitis. CONCLUSIONS: Higher inflammation scores indicated severe disease and Gram-negative infection in post-cataract endophthalmitis.

Late postoperative vitreous cavity hemorrhage after vitrectomy for proliferative diabetic retinopathy-observation versus intervention.

PURPOSE: To analyze the outcome of intervention versus observation for vitreous cavity hemorrhage occurring after a 2-month period of blood-free cavity (late postoperative vitreous cavity hemorrhage-POVCH) in eyes operated by vitrectomy for complications of proliferative diabetic retinopathy (PDR). METHODS: This study was a 10-year retrospective, observational, multi-center study involving eight major vitreoretinal surgical centers across India from January 2010 to December 2019. The primary objective of the study was to assess the visual and clinical outcomes of various management approaches for late POVCH. The key secondary objective was to determine the best management option that prevented recurrence. Patients with follow-up of less than 6 months of POVCH management were excluded. RESULTS: The occurrence of late POVCH was studied in 261 eyes. The median time to occurrence was 7 months (range: 2-87) postvitrectomy/silicone oil removal. The majority (58%) experienced a single, nonrecurring POVCH event. Visual acuity outcome was independent of all management approaches (P = 0.179; mean follow-up 20.7 ± 14.1 months). With watchful observation, spontaneous resolution was noted in 83% (60/72 eyes) of eyes in 81.5 days (interquartile range, 169.75). Silicone oil injection was most effective in preventing recurrence (P < 0.001). CONCLUSION: The current treatment practice of late POVCH management in PDR suggests that watchful observation for at least 3 months could be as efficacious as any surgical intervention.

Endophthalmitis Management Study-A Prospective Randomized Clinical Trial on Postoperative Endophthalmitis Management in India: An Interim Analysis. Endophthalmitis Management Study Report #3.

PURPOSE: An interim analysis of the Endophthalmitis Management Study to examine the outcome of inflammation score (IS)-based treatment and antibiotic susceptibility. DESIGN: A prospective randomized study. PATIENTS AND METHODS: IS was measured on a 0-4 scale from presenting signs in 4 cardinal ocular tissues. The eyes with IS <10 received vitreous tap and intravitreal antibiotics, whereas eyes with IS ≥10 received vitrectomy and intravitreal antibiotics. These eyes were randomized to 2 intravitreal antibiotic combinations: (1) vancomycin and ceftazidime and (2) vancomycin and imipenem. Microbiology workup of undiluted vitreous included microscopy, culture-susceptibility, Sanger, and targeted next-generation sequencing. The clinical and microbiology outcomes were analyzed for advanced (IS = ≥20) and less advanced (IS = <10) endophthalmitis. RESULTS: Interim analysis was performed after the Endophthalmitis Management Study recruited 56.85% (248/436) of patients and completed 54.6% (238/436) of microbiology workup. A 90-day follow-up was completed in 90.8% (168/185) of eligible people. In eyes with IS ≥20, the time to symptoms was shorter (5.8 ± 6.7 vs 8.5 ± 9.1 d; P = 0.015), and the need for additional treatment was higher (95.8% vs 53.1%; P = 0.0267). Good final vision was associated with good presenting vision (r = 0.30) and IS-based treatment decisions (r = 0.170). Microbiology positivity was 55.9%. Eyes with IS <10 had a higher Gram-positive cocci (33.9% vs 4.8%; P = 0.013) infection. Gram-positive cocci were most susceptible to vancomycin (95.7%), and Gram-negative bacilli to colistin (95.7%). CONCLUSIONS: Considering both IS and presenting vision, rather than only one of them, helps in making appropriate management decisions for acute postoperative endophthalmitis.

Prevalence of age-related macular degeneration and associated factors in Indian cohort in a tertiary care setting.

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.

Comparison of prevalent management options to treat acute central serous chorioretinopathy.

Purpose: To study the acute central serous chorioretinopathy (CSC) management strategies practiced at a tertiary eye care center in eastern India. Methods: In a retrospective chart review study, the clinical outcomes of three different management approaches to treating acute CSC were analyzed. Individuals with follow-ups of fewer than 6 months were excluded. Logistic regression analysis was performed to identify the prognostic markers of CSC resolution. Results: In the 10-year study period (January 2013-July 2022), 206 eyes were included. Placebo treatment was the preferred practice (48.5%; n = 100 eyes). Watchful observation without placebo was the management strategy in 30.6% (n = 63) of the eyes, and 20.9% (n = 43) of eyes received focal lasers. Risk factor modification was attempted in all. There was no significant difference in the resolution rate (P = 0.819), time to resolution (P = 0.331), and disease recurrence (P = 0.067) among the groups. Univariate logistic regression analysis did not favor any of the treatment strategies predicting resolution and recurrence. Conclusion: Alternative treatment modes did not score over the natural history of acute CSC regarding disease resolution, vision gain, and disease recurrence. The study reaffirms observation as the standard of care for acute CSC.

Radiation chorioretinopathy: unusual occurrence of intervortex venous anastomosis.

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.

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

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

Bilateral astrocytic hamartoma with vasoproliferative tumour in retinitis pigmentosa.

We report a rare case of a 32-year-old Indian male who presented to the retina outpatient department with a history of sudden worsening of vision in the left eye. There was a background history of poor vision and deficient night vision since childhood. At the first presentation, the best corrected visual acuity was 6/36 and 6/60 in the right and left eye, respectively. Ocular examination revealed waxy pale disc, bone spicule pigmentation, attenuated vessels and epiretinal membrane in the right eye in keeping with retinitis pigmentosa. An astrocytic harmatoma was also present in the right eye. Vitreous haemorrhage in the left eye precluded a view of the fundus. He subsequently had a left pars plana vitrectomy, and intravitreal bevacizumab on account of non-resolving vitreous haemorrhage and a vasoproliferative tumour and astrocytic hamartoma were noticed intraoperatively. He had a good immediate post-operative outcome post-left vitrectomy but subsequently developed left neovascular glaucoma 2 years after. Neovascular glaucoma may be a sequela of vasoproliferative tumour; hence, regular follow-up and monitoring are essential in these patients.

Clinical and imaging characteristics of outer retinal folds in eyes with retinitis.

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.

Prevalence of diabetic retinopathy in urban and rural India: A systematic review and meta-analysis.

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.

Correlating the patterns of diabetic macular edema, optical coherence tomography biomarkers and grade of diabetic retinopathy with stage of renal disease.

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.

Understanding the science of fungal endophthalmitis - AIOS 2021 Sengamedu Srinivas Badrinath Endowment Lecture.

Fungal endophthalmitis is a potentially blinding condition. It is more often reported from Asia, including India. The incidence is lower than bacterial endophthalmitis. But it is relatively more challenging to treat than bacterial endophthalmitis. Many eyes may need therapeutic keratoplasty and/or evisceration. The current mainstays of treatment are vitrectomy irrespective of the presenting vision, intravitreal antifungal agents, and systemic therapy; additionally, the patients could require prolonged treatment with repeat vitreous surgeries and intravitreal injections. Difficulty in clinical diagnosis, delay in microbiological culture, and limited options of antifungal drugs make the treatment more difficult and less rewarding. Three common fungi causing endophthalmitis are Aspergillus, Fusarium, and Candida. The former two are molds, often identified in exogenous endophthalmitis, postoperative and traumatic; the latter is yeast and is more often identified in endogenous endophthalmitis. A faster diagnosis with newer molecular microbiological technologies might help institute treatment earlier than it is currently possible. A target trial using big data from different regions of the world might emulate a randomized clinical trial to design a definite treatment strategy. Given fewer antifungal drugs, one must be mindful of antifungal stewardship to prevent resistance to the existing drugs.

Punctate Inner Retinal Toxoplasmosis: Case Series and Review of Literature.

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.

Fungal Endophthalmitis: Analysis of 730 Consecutive Eyes from 7 Tertiary Eye Care Centers in India.

PURPOSE: To evaluate the clinical and microbiological features of a large cohort with culture-confirmed fungal endophthalmitis across India. DESIGN: Cross-sectional, hospital-based, retrospective medical record review. PARTICIPANTS: Seven large tertiary eye care centers from different regions of India. METHODS: Patient data were pooled from electronic or physical medical records of each participating center. Fellowship-trained vitreoretinal specialists clinically managed all patients, and in-house microbiology laboratories performed all microbiological workups. The clinical and microbiological procedures were broadly uniform across all participating centers. The essential treatment consisted of vitreous surgery as well as intravitreal and systemic therapies with antifungal agents. MAIN OUTCOME MEASURES: Clinical outcome of the causative event and causative fungus. RESULTS: In the period from 2005 to 2020, 7 centers treated 3830 cases of culture-proven endophthalmitis, and of these, 19.1% (n = 730) were cases of culture-confirmed fungal endophthalmitis. It included 46.9% cases of postoperative (87.4% postcataract surgery), 35.6% of traumatic, and 17.5% of endogenous endophthalmitis. The fungi included 39.0% of Aspergillus (high prevalence in central, east, and south zones), 15.1% of Candida (high prevalence in west zone), and 15.9% of Fusarium (high prevalence in north and west zones). The time to symptom development was between 1 week and 4 weeks in more than one third of the patients, except in patients with traumatic endophthalmitis. Less than half of the patients had hypopyon on presentation. The presenting visual acuity (PVA) in most patients was <20/400. Nearly all patients needed vitrectomy and an average of 2 intravitreal injections of antifungal agents. At least 10% of eyes needed therapeutic keratoplasty, and up to 7% of eyes were eviscerated. After treatment, the final (best corrected) visual acuity (FVA) was >20/400 in 30.5% (n = 222) of eyes and >20/40 in 7.9% (n = 58) of eyes, and 12% (n = 88) of eyes lost light perception. A post hoc analysis showed the male sex to be significantly more associated with traumatic endophthalmitis than with postoperative (P < 0.0001) and endogenous (P = 0.001) endophthalmitis, more isolation of Candida species in patients with endogenous endophthalmitis than in those with postoperative (P = 0.004) and traumatic (P < 0.0001) endophthalmitis, better PVA in eyes with Candida species infection (P < 0.0001), and poorer FVA in eyes with Aspergillus species infection. CONCLUSIONS: Fungal endophthalmitis is not uncommon in India. The inclusion of antifungal agents with antibiotics as the first empirical intravitreal therapy before microbiological confirmation should be considered when a fungal infection is suspected.

Scleral Fixation of Intraocular Lens in Aphakic Eyes without Capsular Support: Description of a New Technique.

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.

Prevalence of chronic disease in older adults in multitier eye-care facilities in South India: Electronic medical records-driven big data analytics report.

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.
