Abstract
A man in his late 50s presented with a gradually enlarging, painless, reddish mass on the white portion of his left eye for 2 weeks. His best-corrected visual acuity was 20/20 in both eyes. Slit-lamp examination showed a congested, nodular, elevated lesion on the temporal bulbar conjunctiva with two pustule-like elevations. Anterior segment optical coherence tomography showed a subconjunctival solid mass rather than an abscess or a cyst. Scleral deroofing was performed and a long thread-like object resembling a dead worm was identified. The worm was removed intact, and its histopathology confirmed the diagnosis of Dirofilaria Peripheral blood smear did not show any microfilariae. No recurrences or new lesions were observed during the follow-up examinations at 1 and 5 months post-surgery. This case highlights the importance of considering a parasitic aetiology in cases of nodular or infectious scleritis.

Characteristics of posterior zone I retinopathy of prematurity. Eye (Lond) 2023; 37:3776-3780. [PMID: 37253857 PMCID: PMC10697929 DOI: 10.1038/s41433-023-02603-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 05/12/2023] [Accepted: 05/22/2023] [Indexed: 06/01/2023] Open
Abstract
OBJECTIVE To report the demographic profile and clinical characteristics of retinopathy of prematurity (ROP) in posterior Zone I. METHODS In a partly retrospective (ten years) and partly prospective (one year) study, we analysed the demographic profile and clinical characteristics of babies with ROP in posterior Zone I. RESULTS The study included 130 eyes of 67 infants with a mean gestational age and birth weight of 29.3 (±2.2) weeks and 1217.3 (±381.9) grams, respectively. All babies had received unblended oxygen. In 47 of 51 (91.1%) babies, the weekly weight gain was <100 g (details were not available in 16 babies). The ROP subtypes included aggressive, threshold, hybrid, stage 4, and atypical types in 78 (60%), 20 (15.4%), 11 (8.5%), 15 (11.5%), and 6 (4.6%) eyes, respectively. Fibrovascular proliferation, when present, was prominent nasally, occasionally overriding the disc margin. Extensive arteriovenous tortuosity was more prominent than vascular dilatation. Atypical observations included bleb-like detachment (6 eyes; 4.6%) and candle wax-like preretinal deposits (23 eyes; 17.7%). CONCLUSIONS Retinopathy of Prematurity in posterior Zone I in this cohort was strongly associated with 100% unblended oxygen supplementation, poor weight gain, and multiple systemic co-morbidities. ROP in posterior zone 1 has a distinct profile with several atypical characteristics different from ROP in other zones.

Abstract
PURPOSE To describe the spectrum and demographic distribution of non-oncological retinal diseases in children and adolescents presenting to a multi-tier ophthalmic hospital network in India. METHODS This is a cross-sectional hospital-based retrospective study over nine years (March 2011-March 2020) from a pyramidal eye care network in India. The analysis included 477,954 new patients (0-21 years), collected from an International Classification of Diseases (ICD) coded electronic medical record (EMR) system. Patients with a clinical diagnosis of retinal disease (non-oncological) in at least one eye were included. Age-wise distribution of these diseases in children and adolescents was analysed. RESULTS In the study, 8.44% (n = 40,341) of new patients were diagnosed with non-oncological retinal pathology in at least one eye. The age group-specific distribution of retinal diseases was 47.4%, 11. 8%, 5.9%, 5.9%, 6.4%, 7.6% in infants (< 1 year), toddlers (1-2 years), early childhood (3-5 years), middle childhood (6-11 years), early adolescents (12-18 years) and late adolescents (18-21 years), respectively. 60% were male, and 70% had bilateral disease. The mean age was 9.46 ± 7.52 years. The common retinal disorders were retinopathy of prematurity (ROP, 30.5%), retinal dystrophy (19.5%; most commonly, retinitis pigmentosa), and retinal detachment (16.4%). Four-fifth of the eyes had moderate to severe visual impairment. Nearly one-sixth of patients needed low vision and rehabilitative services, and about 1 in 10 patients required surgical intervention (n = 5960, 8.6%). CONCLUSION AND RELEVANCE About 1 in 10 children and adolescents seeking eye care in our cohort had non-oncological retinal diseases; the common ones were ROP (in infants) and retinitis pigmentosa (in adolescents). This information would help future strategic planning of eye health care in the institution in pediatric and adolescent age groups.

Differentiating Occult Neuroretinitis and Non-Arteritic Anterior Ischaemic Optic Neuropathy: Clinical and Optical Coherence Tomography Characteristics. Neuroophthalmology 2023; 47:208-217. [PMID: 37434671 PMCID: PMC10332201 DOI: 10.1080/01658107.2023.2220778] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 04/01/2023] [Accepted: 05/23/2023] [Indexed: 07/13/2023] Open
Abstract
We report clinical and optical coherence tomography (OCT) differences among patients with occult neuroretinitis and non-arteritic anterior ischaemic optic neuropathy (NAAION). We retrospectively reviewed records of patients with a final diagnosis of occult neuroretinitis and NAAION seen at our institute. Data were collected regarding patient demographics, clinical features, concomitant systemic risk factors, visual function, and optical coherence tomography (OCT) findings at presentation and subsequent follow-up. Fourteen and 16 patients were diagnosed to have occult neuroretinitis and NAAION, respectively. Patients with NAAION were slightly older (median age 49, inter-quartile range [IQR]: 45-54 years, versus 41, IQR: 31-50 years) than patients with neuroretinitis. Seventy-five per cent of patients with NAAION were male versus 43% with neuroretinitis (p = 0.07). Systemic risk factors were present in 87.5% of patients with NAAION versus 21.4% in patients with neuroretinitis (p = 0.001). At presentation, all patients presented with blurred vision, had similar visual function, and had optic disc oedema. In addition, none of the patients had evident retinitis lesions, but 10 (71%) showed evident retinitis lesion at follow-up. Neuroretinitis patients had more often vitreous cells (64% versus 6%, p = 0.001), and subretinal fluid (78.6% versus 37.5%, p = 0.03) than the patients with NAAION. In summary, NAAION patients tended to be slightly older, more often male, and had associated systemic diseases more often than those with neuroretinitis. Neuroretinitis patients more often had posterior vitreous cells and subretinal fluid on OCT. However, larger prospective studies are needed.

Abstract
Aim To report the clinical presentations, management, and factors affecting the outcomes in posterior segment open globe injuries in 2,360 consecutive eyes. Methods This was a retrospective, consecutive, non-comparative interventional case series. All cases with scleral and corneoscleral wounds presenting to these centers from January 2014 to January 2021 were included. The cases were defined according to the Birmingham Eye Traumatology Terminology system (BETTs) classification. The Ocular Trauma Score (OTS) was applied to the dataset. Results Mean age of presentation was 36.63±19.92 years (median 35 years). Penetrating trauma accounted for 70.92%, rupture for 18.6%, perforation for 4.6% and IOFB in 5.88% eyes. In 76.6% the location of injury involved zone I extending till Zone II while in 23.4% it involved Zone II and/or Zone III. Vision at presentation was logMAR 3.03±0.99 and at the last visit was logMAR 2.47±1.42 (p<0.0001). Time interval between presentation to the treatment center and globe repair was 13.93±19.56 hours (median 7.6 hours). Favorable functional outcome was seen in 29.2% eyes and favorable anatomic outcome in 66.9%. Decreasing age at presentation, penetrating injury instead of rupture or perforating injury, a higher OTS, absence of corneal involvement, absence of retinal detachment at presentation and absence of concurrent orbital fracture were associated with a favorable functional outcome (>20/200). Final visual acuity in logMAR correlated with the OTS value calculated at presentation. Conclusions In the absence of retinal detachment and orbital fracture, posterior open globe injuries typically have a favorable functional outcome. OTS correlated with the final visual acuity.

Abstract
Purpose To evaluate the effectiveness and future implications of COVID-related risk stratification for managing retinopathy of prematurity (ROP). Methods A prospective study was conducted at a tertiary eye care center from the beginning of the lockdown in India from 23 March 2020 till the end of the first phase of lockdown on 29 May 2020. We evaluated 200 prematurely born infants (< 34 weeks of gestational age) using the new safety guideline protocols for low-risk babies developed in conjunction with the Indian ROP Society for care during the COVID-19 pandemic. Low risk included babies born at more than 30 weeks of gestational age, post menstrual age 34 weeks or above at presentation, more than 1000 grams of birth weight, and stable systemically with good weight gain. Results New guidelines were implemented in 106 (53%) infants who were low risk while 94 (47%) infants with high risk were followed up as per the old guidelines. Out of the 106 infants (212 eyes) managed by the new guidelines, good outcome (group 1) was seen in 102 (96.2%) infants. Twenty-seven of the 102 infants had some form of ROP and 5 of these infants needed treatment. None of the low-risk babies with no detachment at presentation managed by new guidelines required surgery later (group 2). Two (1.9%) infants came with retinal detachment at presentation and underwent successful surgery (group 3) and two infants (1.9%) were lost to follow up. Conclusion New risk stratification during the COVID-19 pandemic was an efficient and safe strategy in managing low-risk ROP babies.

Abstract
Purpose: To analyze the impact of a revised care plan for retinopathy of prematurity (ROP) during SARS-CoV-2 pandemic in a tertiary eye care facility in eastern India. Methods: In a retrospective study, we analyzed the medical records of babies managed for ROP during the peak of the SARS-CoV-2 pandemic, with particular reference to the challenges, and the revised strategies addressing travel restrictions for five months, from April to August 2020. The strategy included selective referral (babies with higher treatment probability), longer follow-up intervals (babies with non-alarming findings), use of locally available workforce, and teleconsultation whenever feasible. Results: In the given period, 222 babies were examined versus 624 in the preceding year (P = 0.001). The average gestational age, birth weight, and postmenstrual age at presentation were 30.4 weeks, 1.31 kg, and 37.7 weeks, respectively. The first examination was on time in 40.1% of babies but was delayed by a median of 23 days in the remaining babies. In the cohort, 56.7% of babies had any ROP, and 27.9% required treatment (versus 8.8% in the previous year; P < 0.001). The intravitreal anti–vascular growth factor (anti-VEGF) injection was more often used than in the previous year (n = 72 vs 36; P < 0.0001). The treatment outcome was comparable before and after the SARS-CoV-2 lockdown period. There was no report of health issues among the care providers attributable to ROP care. Conclusion: The revised strategy resulted in a smaller pool of babies screened but a larger proportion of babies treated for ROP. This strategy could be used more profitably in future ROP care.

Abstract
Purpose: To evaluate patterns of pediatric vitelliform macular dystrophy (PVMD). Methods: This is a retrospective analysis of Indian children with vitelliform macular dystrophy (VMD) presenting within the first decade of life. Records were evaluated for clinical findings, family screening, and investigative findings including optical coherence tomography (OCT), fundus autofluorescence (FAF), full-field electroretinogram (ERG) and electrooculogram (EOG). Electrophysiology was scrutinized and audited for acquisition and interpretation errors. Findings on follow-up were also recorded. Results: 46 eyes of 24 patients were included. Mean age at presentation was 7.17 ± 2.17 years. Mean follow-up duration was 1.55 ± 1.69 years. Best disease was the commonest type of VMD detected (21 patients), while autosomal recessive bestrophinopathy was seen in three cases. Mean logMAR BCVA was 0.364 which decreased to 0.402 on follow-up. Hyperopia was noted in 29 out of 46 eyes (mean being +3.87 D, range ebing +0.75 to +8.75 D). Four eyes of four children had choroidal neovascular membrane at presentation, while another child developed while in follow-up. Solid type subretinal deposit was the commonest OCT finding (n = 29/38) and central hyper FAF was the commonest pattern (n = 18/32). EOG was available for review in 32 eyes, but was unreliable in 11 eyes. Seven eyes demonstrated complete absence of light rise on EOG. Conclusion: PVMD can present in advanced forms. Progression to complications with loss of visual acuity can happen within the first decade of life. EOG shows grossly suppressed waveforms in the light phase in a large number of such children.

Abstract
Physicians have to play the role of a team leader and counselor and take written informed consent for high-risk surgeries in many cases. This is the first step toward initiating a mutually trustworthy relationship with the patient and family. The situation is more sensitive when vulnerable patients like small premature babies or the elderly are under consideration. In the event of a death, leadership and processes in place become extremely critical. We share our experience and practice pattern during this process, especially suited to India, but the broad principles would apply to most human situations. Hopefully, some of these can be incorporated into the existing training curriculum for team building and the art of effective physician-patient communication that should be intricately woven into the curriculum for the Science of Ophthalmic care.

Abstract
Recent decade has seen a shift in the causes of childhood blinding diseases from anterior segment to retinal disease in both developed and developing countries. The common retinal disorders are retinopathy of prematurity and vitreoretinal infections in neonates, congenital anomalies in infants, and vascular retinopathies including type 1 diabetes, tumors, and inherited retinal diseases in children (up to 12 years). Retinal imaging helps in diagnosis, management, follow up and prognostication in all these disorders. These imaging modalities include fundus photography, fluorescein angiography, ultrasonography, retinal vascular and structural studies, and electrodiagnosis. Over the decades there has been tremendous advances both in design (compact, multifunctional, tele-consult capable) and technology (wide- and ultra-wide field and noninvasive retinal angiography). These new advances have application in most of the pediatric retinal diseases though at most times the designs of new devices have remained confined to use in adults. Poor patient cooperation and insufficient attention span in children demand careful crafting of the devices. The newer attempts of hand-held retinal diagnostic devices are welcome additions in this direction. While much has been done, there is still much to do in the coming years. One of the compelling and immediate needs is the pediatric version of optical coherence tomography angiography. These needs and demands would increase many folds in future. A sound policy could be the simultaneous development of adult and pediatric version of all ophthalmic diagnostic devices, coupled with capacity building of trained medical personnel.

Abstract
Purpose: To report the clinical presentation, microbiology, and management outcome of endogenous endophthalmitis in Indian patients. Methods: Retrospective chart review of culture-positive (vitreous/urine/blood) endogenous endophthalmitis cases treated in tertiary eye care facility in India was done. Results: The study included 173 eyes of 117 patients. Mean patient age was 25.41 ± 20.46 years (median 24 years). Pre-disposing systemic illness could not be elicited in 79 (67.63%) patients. Commonest predisposing systemic condition in patients where it could be detected (n = 79) was pyrexia of unknown origin (25/79 = 32.0%). Following treatment, 45 out of 173 (26.0%) eyes regained vision of ≥20/400. Commonest isolated organism from vitreous was Streptococcus pneumoniae (36 eyes, 20.8%) and fungi were isolated in 24 (13.8%) eyes, the commonest being Candida spp. (8/24, 33.33%). Favorable functional outcome was seen in 26% eyes and favorable anatomic outcome in 43% eyes. Those with an underlying systemic illness were older (P = 0.02), had greater urine culture positivity (P = 0.003), lesser vitreous culture positivity (0.001), greater gram negative etiology (P = 0.0006), and greater fungal etiology (P = 0.01) as compared to those cases without underlying systemic illness. Conclusion: Endogenous endophthalmitis in India often presents in young immunocompetent individuals without any underlying systemic illness and with negative blood or urine microbiologic work up. Underlying systemic illness leads to greater gram-negative and fungal etiology. Overall visual outcome is poor inspite of prompt management.

Abstract
A male infant, born preterm at 32 weeks of gestation, was referred at 36-week postmenstrual age for retinopathy of prematurity (ROP) screening. He had nystagmus, generalised hypopigmentation of skin, hair and eyes with preaxial polydactyly. The fundus was depigmented with prominently visible choroidal vessels. The retinal vessels were dilated, tortuous at zone 1. There was presence of arcading, shunting of vessels with presence of vitreous haemorrhage in the left eye. A diagnosis of aggressive posterior retinopathy of prematurity (APROP) in association with oculocutaneous albinism (OCA) was made.Half-dose intravitreal bevacizumab was used to treat the vascular condition. After 2 weeks, there was complete regression of APROP with a completely mature retina observed at 4 months post-treatment. Herein, we describe the role of red-free light for screening ROP in infants with OCA; challenges in the management of ROP with laser photocoagulation compared with intravitreal anti-vascular endothelial growth factor therapy.

Abstract
A 49-year-old diabetic female was diagnosed to have both eyes proliferative diabetic retinopathy (PDR) and neovascular glaucoma (NVG [rubeosis stage in the right eye and angle-closure stage in the left eye]). The right eye anterior and posterior segment new vessels regressed 2 weeks following intravitreal bevacizumab (IVB) injection. The left eye fundus revealed fibrovascular proliferation (FVP) for which panretinal photocoagulation (PRP) was started and subsequently intracameral bevacizumab (ICB) was injected. Following this intervention, the left eye new vessels of iris regressed but fundus showed multiple peripapillary white-centered intraretinal and subhyaloid hemorrhage suggestive of decompression retinopathy. Ocular decompression retinopathy presents as retinal hemorrhages following the acute lowering of the intraocular pressure (IOP). This case describes the rare occurrence of ocular decompression retinopathy following ICB in a case of PDR with NVG.

Abstract
We report two cases of recalcitrant endophthalmitis, a delayed postoperative fungal endophthalmitis following cataract surgery and an atypical mycobacterial endogenous endophthalmitis associated with infective scleritis. Due to recalcitrant nature of the endophthalmitis, one or more sittings of double freeze and thaw cryotherapy was applied over and adjacent to the infective foci in each case. This cryotherapy was used as an adjunct alongside conventional endophthalmitis management following which resolution of infection was observed in both cases.

Abstract
A 46-year-old male presented with best corrected visual acuity (BCVA) of 20/125 in his right eye. Fundus showed disc edema, multiple yellow outer retinal crops, macular edema and a live motile worm in the subretinal space. Diagnosis of diffuse unilateral subacute neuroretinitis (DUSN) was made and pattern scanning laser photocoagulation (PSLP) was performed along with administration of oral albendazole, diethylcarbamazine and corticosteroids. Complete disappearance of the worm was observed at 2 weeks. At last follow up, final BCVA improved to 20/30. Herein, we report role of PSLP in the management of DUSN.

Abstract
A 40-year-old woman presented with sudden painless diminution of vision in left eye. The best corrected visual acuity was 20/20 in the right eye and 20/400 in the left eye. The vision loss occurred 3 days after the onset of fever with chills and rigour. Rapid diagnostic test and peripheral blood smear examination revealed Plasmodium falciparum malaria. The left eye fundus showed a pale disc with marked attenuation of arterioles. A detailed systemic evaluation including cardiovascular, haematological and angiographic assessments was performed which did not reveal any abnormality. A diagnosis of central retinal artery occlusion (CRAO) associated with uncomplicated P. falciparum malaria was made. In this communication, we report that acute loss of vision in a patient with P. falciparum malaria, CRAO needs to be ruled out.

Abstract
Aim: To evaluate clinical presentation, course and outcomes in patients without a history of penetrating ocular trauma who developed Sympathetic Ophthalmia (SO) following vitreoretinal surgeries Methods: Retrospective review of clinical records of all patients diagnosed and treated as S.O was done . All cases without a previous history of trauma were included and were analyzed with respect to clinical presentations, anatomic and visual outcomes. Results: 175 cases of sympathetic ophthalmia were diagnosed and treated till June 2017. 16 of these cases had undergone a pars plana vitrecomy (PPV) in the past and had no history of prior ocular trauma. SO after vitreoetinal surgeries accounted for 9.14 percent of all cases of SO .In the same duration, till 2017,a total 41365 PPV were done. Thus 0.038 percent of PPV cases developed a SO . 10 patients were males and 6 were females. The median age at presentation was 45.7 years. The time interval from surgery to diagnosis of sympathetic ophthalmia ranged from 22 days to 4 years after undergoing a surgery. The mean visual acuity in the sympathizing eye was 1.26 logMAR (snellens equivalent of 20/320) which improved to 0.62 logMAR(snellens equivalent of 20/80) after treatment. The most common anterior segment finding was non granulomatous anterior uveitis, seen in 8 cases (50%) while neurosensory detachments were the most common posterior segment presentation (10 cases, 62.5%).12 patients had undergone more than 1 surgery (mean number of surgeries was 1.88). 10 patients had undergone a sutureless PPV (6 cases of 23 gauge and 4 cases of 25 gauge vitrectomy) while 4 patients had undergone a 20 gauge vitrectomy where all sclerotomies were sutured after surgery All patients were treated with systemic steroids and immunosuppresants and 15 out of 16 patients showed significant improvement in the final visual acuity in the sympathizing eye Conclusions: Sympathetic ophthalmia after vitreoretinal surgeries is a rare but potentially sight threatening disease occurring in 0.038 percent of all cases of Pars Plana Vitrectomy. Presence of inflammation in the fellow eye after a vitreoretinal surgery in the other eye should alert the surgeon to possibility of sympathetic ophthalmia.

Abstract
AIMS To review the clinical profile and report the microbiology and treatment outcomes of endophthalmitis following suture removal. METHODS In this multi-center, retrospective interventional case series, 11 eyes of 11 patients who developed endophthalmitis following suture removal from January 2006 to December 2017 were reviewed. RESULTS Nine of the 11 patients developed a culture-proven, acute onset endophthalmitis [5.3 ± 3.1 days (range 2-10 days)]. Mean age was 15.8 ± 21.2 years (median 7; range, 1-66 years). Presenting visual acuity was extremely low ranging from light perception (PL) to counting fingers close to face (CFCF) at the time of diagnosis of endophthalmitis. Out of the 11 patients, 8 belonged to the pediatric age group; four out of those eight had loose sutures secondary to cataract surgery, two patients had loose sutures secondary to penetrating keratoplasty and 1 case each had loose sutures secondary to corneal tear repair and secondary IOL implantation, respectively. Streptococcus pneumoniae was the most common organism and was identified in seven cases and was susceptible to vancomycin in all these cases. Other bacterial isolates were Haemophilus influenzae and Achromobacter denitrificans. Three out of the 11 eyes had visual outcome of 20/200 or better. Six eyes were phthisical and one eye was eviscerated. Mean follow-up was 26.3 ± 31.2 weeks (range 2-92 weeks). Visual outcomes ranged from 20/40 to no light perception at the last follow-up. CONCLUSIONS Endophthalmitis following suture removal though rare, is observed most commonly in the pediatric population and has an acute and a fulminant course. Streptococcus pneumoniae was the most commonly isolated microorganism. Visual acuity outcomes were poor despite prompt recognition of endophthalmitis and appropriate antibiotic therapy.

Abstract
Purpose: To identify optical coherence tomography-angiography (OCT-A) findings to predict treatment response during anti-vascular endothelial growth factor (VEGF) therapy in eyes with para foveal telangiectasia (PFT) group II. Methods: In this retrospective series, Twelve eyes of seven patients diagnosed with PFT group II without evidence of sub-retinal neovascular membrane (SRNVM) clinically or on spectral domain-OCT (SD-OCT) were included. All patients underwent OCT-A on the Topcon DRI OCT Triton® with 4.5 mm macula scans. The patients with abnormal vascular nets were further classified into type A and B nets and administered intravitreal anti-VEGF therapy. Visual acuity and size of type A and B nets were evaluated pre- and post-injection. Paired t-test and intraclass correlation were used to analyse data. Results: Patients with type A net showed significant improvement in visual acuity (logMAR 0.38, P = 0.0047). The size of type A net showed statistically significant decrease (P = 0.0008) on 6 month follow up. Type B net did not show statistically significant difference in visual acuity or size following anti-VEGF therapy. Conclusion: OCT-A plays an important role in early detection of possible neovascular nets (type A), in the absence of obvious SRNVM. Treatment decisions based on OCT-A may be helpful to achieve better visual outcome.

Abstract
Purpose: To determine the predictive values of baseline optical coherence tomography (OCT) abnormalities on 12-month visual acuity changes in eyes with macular edema (ME) caused by branch retinal vein occlusions (BRVO). Methods: We performed a post hoc analysis of data from 75 participants in the 12-month MARVEL trial. OCT abnormalities at baseline, including ganglion cell layer cystoid spaces (GCL), intraretinal hyper-reflective dots, and central subfield thickness (CST), were correlated with improvements in visual acuity and the number of anti-vascular endothelial growth factor injections required using a multivariate regression model. Results: Eyes with baseline CST > 500 μm had greater visual gains compared to those with CST <500 μm (+21.09 vs +16.08 letters, P = 0.04). Eyes with hyper-reflective dots (+13.97 vs +19.93 letters, P = 0.02), and GCL cysts (+9.8 vs +18.9, P = 0.003) had inferior gains in visual acuity. Neurosensory macular detachments at the baseline did not affect gains in visual acuity. Ninety percent of the gain in visual acuity was recorded after two injections and was maintained until month 12. Conclusion: Baseline OCT of <500 μm, hyper-reflective dots, and GCL cystoid spaces are associated with poorer gains in visual acuity. Most of the visual gain occurs after two injections.

Abstract
Purpose To report a novel clinical sign in patients with intraocular tuberculosis. The current study is an observational consecutive case series of patients diagnosed with intraocular tuberculosis managed at a tertiary eye care centre from June 1, 2012 to December 31, 2015. Observations The diagnosis of intraocular tuberculosis was made in 6 patients based on ocular features suggestive of tuberculosis along with a positive tuberculin skin testing and chest X-ray consistent with tuberculosis. All patients presented with decreased visual acuity ranging from 20/25 to 20/400, anterior chamber reaction, vitritis, multifocal choroiditis and vasculitis. All patients had an area of active chorioretinitis within the zone of pre-existing chorioretinal atrophy, apart from various other signs suggestive of intraocular inflammation. All patients were started on anti-tubercular therapy for a period of 9 months alone or in combination with oral corticosteroids tapered over 3–4 months. A prompt response to the treatment with resolution of chorioretinitis within the chorioretinal atrophy occurred in all patients. In addition, there was resolution of vitritis and improvement in the visual acuity ranging from 20/20 to 20/40 at last follow-up. Conclusions and importance and Importance: Active chorioretinitis within an area of chorioretinal atrophy is a novel clinical sign that may indicate intraocular tuberculosis.

Abstract
To report the clinical and microbiological characteristics of infectious endophthalmitis after Boston type I keratoprosthesis (B-K-Pro) implantation. Retrospective analysis of 45 eyes that received a B-K-Pro type 1 between 2009 and 2012 was performed. Five eyes with a diagnosis of exogenous endophthalmitis after B-K-pro type 1 were identified and information about demographic data, indication for K-Pro, post-operative bandage contact lens use, post-operative prophylactic antibiotic use, timing and clinical presentation of endophthalmitis, gram stain and culture results of intraocular fluid and preoperative and post-operative visual acuity were collected. The incidence of endophthalmitis was 11.1 % (5 of 45 eyes) and average time to develop endophthalmitis was 5.62 months (range 2 days to 8 months). Mean patient age was 31.4 years (5 to 65 years). The surgical indications included corneal injury due to chemical burns (n = 2), multiple failed grafts secondary to microbial keratitis (n = 2) and congenital glaucoma with congenital herpetic keratitis (n = 1). Post-Boston K-Pro, the visual acuity ranged from light perception (LP) to 20/50. K-pro was explanted in 4 patients. There was bacterial and fungal growth in two patients each and one vitreous did not grow anything. All the eyes were phthisical at last visit. Infectious endophthalmitis after K-Pro implantation in our study had a higher incidence, early onset and extremely poor visual outcome compared with post-cataract surgery endophthalmitis, as reported in literature. Not only bacterial but also fungal infections are an important etiology for infectious endophthalmitis in these cases.

Abstract
PURPOSE The purpose of this study was to prospectively study the efficacy of grid laser combined with intravitreal bevacizumab or ranibizumab in eyes with macular edema due to branch retinal vein occlusion. PATIENTS AND METHODS Treatment-naïve eyes were enrolled to receive injections of ranibizumab or bevacizumab. During the first 6 months, patients were evaluated monthly and injected if the best-corrected visual acuity changed by five or more letters or fluid was noted on spectral domain optical coherence tomography (OCT); during the next 6 months, patients were evaluated bimonthly and injected only if the best-corrected visual acuity decreased by five or more letters with the associated fluid. Grid laser photocoagulation was performed if there was fluid on OCT and was repeated if patients were eligible after a minimum interval of 3 months. RESULTS The mean numbers of ranibizumab and bevacizumab injections were, respectively, 3.2±1.5 and 3.0±1.4 in the first 6 months and 0.3±0.6 and 0.3±0.6 in the last 6 months. Moreover, 55/75 (73.33%) participants did not receive any injections in the last 6 months. The mean reductions in central retinal thickness at 12 months were 165.67 μm (P<0.001; 95% confidence interval -221.50 to -135.0) in the ranibizumab group and 184.78 μm (P<0.001; 95% confidence interval -246.49 to -140.0) in the bevacizumab group (P=0.079). More patients in the bevacizumab group compared to those in the ranibizumab group required rescue laser at 12 months (20 vs eleven; P=0.06). CONCLUSION Bimonthly evaluations after month 6 with very few pro re nata injections were effective in maintaining visual gains achieved during the first 6 months. Grid laser photocoagulation is effective in maintaining the vision even in the presence of fluid on OCT, although it's required more often in patients treated with bevacizumab.
