RESUMO
PURPOSE: To report the electrophysiological and neuroimaging findings in a patient who developed visual loss after attempted suicide by hanging. METHODS: A 45-year-old male presented with bilateral visual loss and difficulty in walking following a suicide attempt by hanging six months ago. He underwent a complete ophthalmologic examination, posterior segment optical coherence tomography (OCT), various electrophysiological tests and neuroimaging. RESULTS: His bilateral best-corrected visual acuity was logMAR 1.08. Intraocular pressures and ocular examination were normal except for bilateral temporal disk pallor. Macular OCT showed bilateral ganglion cell layer-inner plexiform layer complex thinning. Electroretinogram showed reduced b/a wave amplitude ratio in all the dark- and light-adapted International Society for Clinical Electrophysiology of Vision protocols in both the eyes. Pattern-reversal visually evoked potential (VEP) showed delayed latency of the P100 component in both the eyes. Electrooculography showed a normal light peak-to-dark trough ratio in both the eyes. Magnetic resonance imaging (MRI) brain showed chronic infarct and gliosis in both the occipital lobes. MR angiography showed pruning of P4 segments of both the posterior cerebral artery. Perfusion imaging showed reduction of perfusion in both the parieto-occipital lobes. CONCLUSION: Hanging survivors can develop visual loss after their recovery. The visual loss may be a result of simultaneous ischemic insult to the occipital lobe cortex, optic nerve and retina.

AIM: To compare the sensitivity of Optomap Panoramic 200 and Clarus 500 in detecting peripheral retinal breaks that required treatment. METHODS: This prospective study enrolled consecutive patients undergoing laser for treatment-requiring peripheral retinal breaks from May 2019 to July 2019. The patients first underwent indirect ophthalmoscopy examination with scleral indentation by a retinal consultant and then ultra-widefield imaging by a single trained technician on Optomap 200 and Clarus 500 in all nine ocular gazes. The images were analysed by two independent investigators to look for the number and location of the breaks. The sensitivity of each platform was calculated as the number of treatment-requiring breaks identified by the system divided by the number of breaks identified on clinical examination. RESULTS: Clinical examination of 49 eyes (41 patients) showed 116 treatment-requiring breaks. Overall sensitivity for identifying such breaks for Optomap and Clarus was 80.2% (n = 93) and 74.1% (n = 86) respectively (p = 0.274). The sensitivities in superior (p = 0.665), temporal (p = 0.146) and inferior (p = 0.889) quadrants were statistically similar for both the platforms. The sensitivity of Optomap was slightly higher than Clarus in emmetropic (p = 0.046) and phakic (p = 0.061) eyes, but similar in myopic (p = 0.448) and pseudophakic (p = 0.191) eyes. CONCLUSION: The ability to detect treatment-requiring retinal breaks is similar for both Optomap and Clarus systems.

INTRODUCTION: Nearly 6.8 million people in India have vision less than 6/60 in at least one eye due to corneal diseases; of these, about a million had bilateral involvement. PURPOSE: To identify the challenges faced; the trends in collection, storage and utilisation of corneal tissues in an eye bank in north India. MATERIALS AND METHODS: The past records of Eye Bank linked to a tertiary hospital in northern India were analysed from November'1999 to October'2015 with respect to number of eye donations per year, donor demographics and utilisation of corneal tissues. RESULTS: The number of donations during the first 6 years were 100, 279 in the next 5 years and 473 in the last 5 years. The mean donor age was 63.2 ± 19.5 years. The percentage of donors less than 30, 31-60 and more than 60 years was 10%, 28% and 62%. Forty-two percent donations were from the hospital. The average time between the death and enucleation was 4.74 ± 5.31 hours. The percentage of corneas used in the donor age groups less than 30, 31-60 and above 60 years was 61.9%, 61.6% and 53.8%, respectively. The usability rate of the corneas from home and hospital was 63.7% and 55.3%, respectively. CONCLUSIONS: The eye bank had a lukewarm response in the beginning, but gained momentum with time. The myths and beliefs prevalent in our society deter people from donating eyes freely. Each eye bank needs to individualise its problems and find solutions for adequate procurement and utilisation of tissue.

BACKGROUND: To compare outcomes and complications of pars plana vitrectomy (PPV) using a three-dimensional heads-up visualisation system (digitally assisted vitreoretinal system, DAVS) versus conventional analog microscope (CAM) in primary rhegmatogenous retinal detachment (RRD). METHODS: This prospective interventional institutional study evaluated 60 eyes of 60 subjects with primary RRD undergoing PPV between September 2017 and February 2018. Subjects were randomly put into DAVS and CAM group and pre-operative ocular characteristics and final outcomes recorded at each visit. All subjects were followed up for a duration of 6 months. Main outcome measures recorded were post-operative retinal status, visual acuity (VA), intraocular pressure (IOP) and surgical complications. RESULTS: Overall final retinal attachment at 6 months was 91.7% (90% in DAVS eyes and 93.3% in CAM eyes; p = 0.999). Final VA improved significantly from baseline in both groups (p < 0.001). Overall, VA improved to > = 20/40 in 18.3% eyes (6 DAVS, 5 CAM). Median duration of silicone oil endotamponade was 3.5 months (3.5 months in DAVS, 3 months in CAM). Redetachment rate in the series was 25% (20% in DAVS, 30% in CAM). Post-operative proliferative vitreoretinopathy grade C and more was present in 15% of eyes (10% in DAVS, 20% in CAM). Average duration of surgery was 37 ± 6.2 min in DAVS group and 39.8 ± 6.6 min in CAM group (p = 0.09). All steps of vitrectomy could be performed with relative ease and comfort with the DAVS platform. CONCLUSION: Anatomical and functional outcomes of RRD were favourable with DAVS and comparable to that with conventional microscope surgery.

AIM: To evaluate the outcome and safety profile of short-term perfluorocarbon liquids (PFCL) tamponade in comparison with buckle-vitrectomy in case of rhegmatogenous retinal detachment (RRD) associated with choroidal detachment (CD). METHODS: Records of patients who underwent surgery for RRD/CD from January 2016 to July 2019 were reviewed retrospectively. The patients were allocated into two groups-group 1 patients underwent buckle-vitrectomy, while those in group 2 underwent a two-staged vitrectomy with short-term (5 days) PFCL tamponade. RESULTS: The study included 33 eyes (33 patients) with mean age of 50.3 ± 17.2 years. Group 1 included 15 patients, while group 2 included 18. The pre-operative characteristics were similar in both the groups. The mean pre-operative intraocular pressure in group 1 and 2 was 9.1 ± 4.0 and 8.6 ± 5.2 mmHg, respectively (p = 0.755). Retinal re-attachment after single surgery was achieved in 10 (66.7%) and 14 eyes (77.8%), respectively. All the eyes achieved retinal re-attachment after repeat surgery in both the groups (1.40 vs 1.39 surgeries, p = 0.963). Post-surgery visual improvement was seen in 13 (86.7%) and 17 eyes (94.4%), respectively (p = 0.579). Final visual acuity of ≥ 6/60 was obtained in 7 (46.7%) and 9 eyes (50.0%), respectively (p > 0.999). None of the patients needed retinectomy during repeat surgery. None of the patients experienced exaggerated inflammation or intractable raised IOP spike which could not be controlled with medications. CONCLUSION: Surgical outcomes were similar in both the groups. No clinically apparent toxicity was seen with post-operative short-term PFCL tamponade. Two-staged surgery is a good alternative to buckle-vitrectomy for eyes with RRD associated with CD.

AIM: To evaluate the incidence and clinical indications for which eyes were treated for retinopathy of prematurity (ROP) outside the guidelines set by International Classification of ROP (ICROP). METHODS: Medical records of the patients treated at a single tertiary care ophthalmology hospital for ROP from January 2016 to December 2019 were retrospectively analysed to evaluate the indications for which they were treated. RESULTS: Out of 241 eyes, 33 eyes (13.7%) were treated outside the guidelines. The reasons for the treatment outside the guidelines were structural changes (n = 24, 72.7%), persistent stage 3 ROP that did not show any sign of regression for 6 weeks (n = 7, 21.2%) and active ROP with fellow eye being treated (n = 2, 6.1%). The recorded specific structural changes were tangential traction with temporal vessel straightening concerning for macular distortion and ectopia (n = 5, 15.2%), and stage 3 neovascularisation or ridge with anteroposterior traction with risk of progression to stage 4 disease (n = 19, 57.6%). Pre-plus disease was present in 11 eyes (33.3%).After the treatment, ROP stages regressed and retinal vessels grew either until the ora or at least into zone III in all the treated eyes. None of the eyes showed worsening of structural changes after treatment. The mean follow-up of the patients was 12.4 ± 11.7 months. CONCLUSION: Experts occasionally recommend treatment in eyes with disease milder than type 1 ROP. This study may help paediatric retinal practitioners in decision-making in borderline cases.

PURPOSE: To describe clinical presentation, morphological features and surgical outcomes of macular hole (MH) secondary to retinal vein occlusion (RVO). METHOD: This prospective interventional study evaluated eight eyes with atypical MH (secondary to RVO) and data regarding medical management, pars plana vitrectomy, postoperative anatomical hole closure, visual acuity improvement, morphological features of hole were noted till the last follow-up. RESULTS: Eight eyes with full-thickness MH in an RVO eye were followed-up for a minimum period of 3 months postoperatively. Five subjects had a RVO episode which occurred more than 6 months before the onset of the recent symptoms (Group 1; 4 branch RVO and 1 central RVO), and 3 subjects had a recent onset branch RVO within 6 months (Group 2). All FTMH cases except one showed closure at the last follow-up. Visual acuity of all eyes improved from 0.91 ± 0.57 logMAR to 0.5 ± 0.3 logMAR (p = 0.093). At baseline, visual acuities of the two groups had no significant difference. Postoperatively, group 1 holes had better visual prognosis, than Group 2 holes, further substantiated by persistence of subretinal fluid in Group 2 eyes till last follow-up. Minimum hole diameter was higher in the recent RVO group, although anatomical closure was obtained in all of these eyes. Most holes had favorable morphological hole features like raised configuration with rounded edges. CONCLUSION: In the presence of favorable morphological features, secondary macular holes associated with retinal vein occlusion may show optimal outcomes after surgery. It is not clear whether acutely created holes in recent onset RVO should be operated early. Older holes may have better prognosis.

AIM: To evaluate the signs and symptoms of dry eye after phacoemulsification; effects on the status of ocular surface using impression cytology; and associated risk factors. METHODS: Prospective study included 50 eyes (50 patients) with no dry eye signs or symptoms, who underwent clear corneal phacoemulsification for senile cataract. Dry eye indices used included Ocular Surface Disease Index scoring, Schirmer I test, tear break up time, tear meniscus height, corneal fluorescein staining, lissamine green staining and goblet cell density (GCD) with the help of impression cytology. Primary outcome measures included post-operative changes in the dry eye indices. Secondary outcome measures included correlation of the dry eye signs and symptoms with various risk factors. RESULTS: Aggravation of both the signs and symptoms of dry eye were noted in immediate post-operative period. The sharp deterioration was followed by a recovering trend towards the end of sixth week. A decrease in GCD was also noted. Risk factors for deterioration include age, duration of exposure to microscope light and effective phacoemulsification time. Diabetic status, socio-economic status and site of incision did not have any effect on dry eye status. CONCLUSION: There is a transient deterioration of "dry eye" status post-phacoemulsification. The patients should be carefully counselled about the evanescent nature of the disease. Incision can be given at the site of high corneal curvature to neutralize astigmatism without any fear of inducing dry eye. Minimum light exposure and ultrasound energy should be used during the surgery.

BACKGROUND: The anatomical success rate of macular hole surgery ranges around 93-98%. However, the prognosis of large macular holes is generally poor. The study was conducted to compare the anatomical and visual outcomes of Internal Limiting Membrane (ILM) peeling vis-a-vis inverted ILM flap for the treatment of idiopathic large Full-Thickness Macular Holes (FTMH). METHODS: This was a prospective randomized control trial. The study included patients with idiopathic FTMH, with a minimum diameter ranging from 600 to 1500 µm. The patients were randomized into Group A (ILM peeling) and Group B (inverted ILM flap). The main outcome measures were anatomical and visual outcome at the end of 6 months. Anatomical success was defined as flattening of macular hole with resolution of the subretinal cuff of fluid and neurosensory retina completely covering the fovea. RESULTS: There were 30 patients in each group. The mean minimum diameters in Group A and B were 759.97 ± 85.01 µm and 803.33 ± 120.65 µm respectively (p = 0.113). The mean base diameter in group A and B was 1304.50 ± 191.59 µm and 1395.17 ± 240.56 µm respectively (p = 0.112). The anatomical success rates achieved in Group A and B were 70.0 and 90.0% respectively (p = 0.125). The mean best-corrected visual acuity (BCVA) after 6 months was logMAR 0.65 ± 0.25 (Snellen equivalent, 20/89) in Group A and logMAR 0.53 ± 0.20 (Snellen equivalent, 20/68) in Group B (p = 0.060). The mean improvement in BCVA was 1.4 lines and 2.1 lines in groups A and B respectively (p = 0.353). BCVA≥20/60 was achieved by 13.3 and 20.0% in group A and B respectively (p = 0.766). CONCLUSION: The anatomical and functional outcome of Inverted ILM flap technique in large FTMH is statistically similar to that seen in conventional ILM peeling.

Retinoblastoma is the most common intraocular tumor of childhood. About 95% of retinoblastoma cases are diagnosed before the age of 5 years. Not more than 30 cases of Adult-onset retinoblastoma have been reported in literature. A 32 year old male presented with a painful blind eye. There was sudden loss of vision accompanied by severe pain and redness in right eye about 1 year ago, for which some surgery was done with neither a gain in vision nor any relief from pain. Then he was put on maximum tolerable medical therapy, later cyclocryotherapy was done. Now he presented to us with complains of extreme pain and bleeding from right eye since 2 days. There is no history of any ocular trauma. Right eye had no perception of light & showed anterior staphyloma with perforation. Right eye evisceration was done & material sent for histopathological examination, which revealed an adult-onset retinoblastoma. CECT scan revealed thickening of optic nerve throughout its entire length with contrast enhancement. He was further taken up for enucleation of residual sclera with maximum optic nerve stump removal to reconfirm the diagnosis. Histopathological examination revealed tumor deposits present in orbital soft tissue, resection margins and optic nerve cut end.Retinoblastoma presenting in adult age creates a diagnostic dilemma because of its low frequency and atypical features. We want to highlight the importance of high clinical suspicion and imaging modalities before taking any patient for evisceration with unexplained vision loss. One should send the eviscerated material for histopathological examination.

AIM: To report the outcomes of the "inverse drainage Nd:YAG laser membranotomy" technique for the management of pre-macular hemorrhage (PMH), which has its inferior margin near the fovea. METHODS: This retrospective study included eyes with PMH, with its inferior margin located within 0.5 disc-diameter (DD) of the fovea. Laser membranotomy was performed near the superior margin of PMH followed by intravitreal injection of 0.3â mL undiluted sulphur hexafluoride (SF6) gas. The patients were advised to maintain a prone position for three days. RESULTS: Twenty patients (20 eyes) with a mean age of 46.1 ± 18.6 years were included in the study. The mean duration of symptoms was 6.9 ± 7.0 days. The mean size of PMH was 4.1 ± 1.2DD. The causes of PMH were Valsalva retinopathy (n = 11) and retinal artery macroaneurysm (RAM, n = 9). The mean maximum height of the blood collection, measured by optical coherence tomography (OCT), within 1 disc-diameter from the inferior and superior borders of the PMH was 738.9 ± 232.9µm and 1240.6 ± 338.1µm respectively (p = 0.001). The mean best-corrected visual acuity (BCVA) improved from logMAR 1.32 ± 0.44 (Snellen equivalent, 20/418) to logMAR 0.11 ± 0.20 (Snellen equivalent, 20/26) (p = 0.001). Vitrectomy was not required in any case. Persistent pre-macular cavity, macular hole, epiretinal membrane (ERM), intra-ocular pressure spike, or rhegmatogenous retinal detachment (RRD) was not noted in any patient. CONCLUSION: This technique can be safely used to treat eyes with PMH having its inferior margin near the fovea.

AIM: To report the management of a neonate who presented with simultaneous bilateral central retinal vein occlusion (CRVO) secondary to septicemia. DESIGN: Case Report. RESULTS: A full-term infant was treated for neonatal sepsis with thrombocytopenia. He presented with poorly dilating pupil, disc edema, dilated retinal veins, perivascular exudation, retinal hemorrhages in all four quadrants radiating from the optic nerve to the ora serrata (no Roth spots), with cystoid macular edema (CME) in both the eyes. His TORCH serology was negative and peripheral blood film was normal. He was diagnosed as presumptive bilateral inflammatory CRVO with CME secondary to septicemia. He received bilateral intravitreal bevacizumab injections. After the injection, his pupils dilated completely while retinal hemorrhages and CME reduced. CONCLUSION: CRVO may present as a rare complication in neonates suffering from septicemia. Apart from the systemic treatment, aggressive ocular treatment is needed to salvage the eyes with severe ischemia.

Purpose: To explore the vitreous humor proteome from type 2 diabetes subjects with proliferative diabetic retinopathy (PDR) in the Indian population. Methods: We performed mass spectrometry-based label-free quantitative analysis of vitreous proteome of PDR (n = 13) and idiopathic macular hole (IMH; control) subjects (n = 14). Nine samples of PDR and 10 samples of IMH were pooled as case and control, respectively, and compared. Four samples each of PDR and IMH were analyzed individually without pooling to validate the results of the pooled analysis. Comparative quantification was performed using Scaffold software which calculated the fold changes of differential expression. Bioinformatics analysis was performed using DAVID and STRING software. Results: We identified 469 proteins in PDR and 517 proteins in IMH vitreous, with an overlap of 172 proteins. Also, 297 unique proteins were identified in PDR and 345 in IMH. In PDR vitreous, 37 proteins were upregulated (P < 0.05) and 19 proteins were downregulated compared to IMH. Protein distribution analysis clearly demonstrated a separation of protein expression in PDR and IMH. Significantly upregulated proteins included fibrinogen gamma chain, fibrinogen beta chain, and carbonic anhydrase 1 and downregulated proteins included alpha-1-antitrypsin, retinol-binding protein 3, neuroserpin, cystatin C, carboxypeptidase E and cathepsin-D. Conclusion: Diabetic retinopathy pathogenesis involves proteins which belong to inflammation, visual transduction, and extracellular matrix pathways. Validation-based experiments using enzyme-linked immunosorbent assay (ELISA) or western blotting are needed to establish cause and effect relationships of these proteins to the disease state, to develop them as biomarkers or drug molecules.

Congenital retinal macrovessel (CRM) is defined as a large aberrant blood vessel that traverses through the central macula. It can have large tributaries extending on both sides of the horizontal raphe. The condition is typically asymptomatic. However, visual loss may be reported in case of associated branch retinal artery occlusion, cavernous haemangioma, retinal artery macroaneurysm, retinal deep capillary ischaemia, retinal detachment and vitreous haemorrhage. However, association of CRM and foveal hypoplasia has rarely been reported.We report multimodal imaging in a patient who was presented with visual loss due to foveal hypoplasia secondary to CRM.

Phakomatoses are a group of congenital disorders characterised by hamartomatous lesions of the skin as well as the central and peripheral nervous systems. The presence of naevus flammeus or port-wine stain is a characteristic feature of many such disorders including Sturge-Weber syndrome (SWS), Klippel-Trenaunay syndrome (KTS) and Phakomatosis pigmentovascularis (PPV).We describe the ocular findings in a patient with coexisting PPV, SWS and KTS.

We report a patient who developed frosted branch angiitis (FBA) and was diagnosed 1 month after the penetrating eye injury (PEI) repair. A 31-year-old male with no systemic comorbidities presented with defective vision following trauma to his left eye while cutting wood. His best-corrected visual acuity (BCVA) was 20/200. Anterior segment examinations showed a zone I full-thickness corneal tear with iris tissue incarceration. There was no clinical evidence of intraocular foreign body (IOFB) or endophthalmitis. He underwent PEI repair with iris abscission on the same day with intracameral moxifloxacin injection. His BCVA on postoperative day 45 was 20/200. Examination showed a resolving vitreous hemorrhage, venous tortuosity, and retinal perivascular infiltration affecting the venules from the posterior pole up to the periphery. He was treated with oral and topical steroids. The clinical signs resolved completely and BCVA improved to 20/20 after 1 month of treatment. FBA can complicate the recovery of eyes after PEI repair, even in the absence of endophthalmitis or sympathetic ophthalmia. A thorough search for IOFB or its tell-tale signs should be done in such eyes.
RESUMO
Pre-macular haemorrhage (PMH) can cause profound visual loss. Some surgeons prefer neodymium-doped yttrium aluminium garnet (Nd:YAG) hyaloidotomy as the first line of treatment due to being an easy technique and having a high success rate. However, the use of high energy close to the fovea can lead to various macular complications. We present a case of a patient who presented with PMH secondary to anaemic retinopathy. He underwent Nd:YAG laser hyaloidotomy, but developed a full-thickness macular hole. He further underwent vitrectomy and a type 1 closure was achieved. However, the visual gain was poor due to the large hole size and the collateral thermal damage. The hole may not close spontaneously, thus requiring surgical intervention. The surgical outcome of these holes depends on the size of the hole and the collateral thermal damage caused during the laser procedure.

PURPOSE: To evaluate the clinical presentation, management, and outcome of eyes with an inadvertent globe perforation during peribulbar or retrobulbar block. METHODS: This retrospective study evaluated the eyes which had an accidental globe perforation during local ocular anesthesia from 2012 to 2020. The patients were divided into three groups: group 1, Clear media with no rhegmatogenous retinal detachment (RRD); group 2, significant vitreous hemorrhage (VH) precluding the retinal view without RRD; and group 3, RRD with/without VH. RESULTS: Twenty-five patients were included in the study. The mean axial length (AL) was 24.7 ± 2.7 mm (range, 20.9-31.2 mm). The most common presenting feature was VH (n = 14). The treatment included retinal laser barrage (n = 7) and vitrectomy (n = 17). Retinal breaks were identified in all the eyes (total breaks = 37). The mean presenting best-corrected visual acuity in groups 1, 2, and 3 were logarithm of the minimum angle of resolution 0.79 ± 0.73, 1.82 ± 0.78, and 2.13 ± 0.59 respectively. All the treated patients had an attached retina at the last follow-up. The mean final best-corrected visual acuity for each group was logarithm of the minimum angle of resolution 0.59 ± 0.79, 0.48 ± 0.26, and 1.25 ± 0.64, respectively (p = 0.006). The development of RRD was associated with a larger AL (p = 0.015); while the development of significant VH associated with the superior location of the perforation (p = 0.015), late recognition of the perforation (p = 0.004), and multiple perforations (p = 0.015). CONCLUSIONS: Early recognition and intervention in eyes with an inadvertent perforation can lead to a good outcome. Eyes with a longer AL, superior, and multiple perforations are at higher risk of developing complications like RRD and VH. Complications like RRD, macular injury, and vascular occlusion are risk factors for poor prognosis.
