RESUMO
A 46-year-old female with preoperative vision 6/18 N18 (LogMar 0.5) in re and posterior subcapsular cataract underwent an uneventful phacoemulsification surgery under a peribulbar block. On the postoperative day 2, she complained of no visual gain in the operated eye. The reported vision was counting fingers close to the face. Through multimodal imaging (MMI), a diagnosis of branched retinal artery occlusion (BRAO) was made. A detailed consultation and history taking with the patient revealed a concealed history of four miscarriages in the past. A detailed systemic blood workup revealed antiphospholipid antibody (APLA) positive. BRAO postuneventful cataract surgery is a devasting outcome for the surgeon and patient undergoing surgery. The report focuses on the importance of taking detailed past medical history and usage of MMI early to rule out and diagnose unexpected scenarios. We suggest BRAO in our patient was a result of emboli formation, which is a common element in APLA-positive patients.
RESUMO
Polypoidal choroidal vasculopathy (PCV) is a vascular disease of the choroid that leads to hemorrhagic and exudative macular degeneration. It may cause significant vision loss and thus affect the quality-of-life and psychological well-being. Non-invasive, non-ICGA-based OCT criteria have shown reliable results to plan adjunct photodynamic therapy (PDT) treatment, with the complete and consistent coverage of polypoidal lesions (PL) and branching neovascular network (BNN). The safety and efficacy of anti-vascular endothelial growth factor (anti-VEGF) monotherapy and its combination with verteporfin PDT have been established. However, treatment is still challenging due to frequent follow-ups, non-availability of PDT, and need for multiple anti-VEGF injection visits that increase the treatment burden and lead to patients being lost to follow-up. Effective treatments that prolong intervals between injections while maintaining vision and anatomical gains remain a critical unmet need. Longer acting molecules, like brolucizumab, have shown non-inferiority in BCVA gains and superior anatomical outcomes compared to other anti-VEGF agents. Newer therapies in the pipeline to enhance the efficacy and longevity of treatment include Faricimab and a port delivery system (PDS). This review summarizes the most recent diagnostic and treatment approaches in PCV to offer better treatment avenues.
RESUMO
PURPOSE: To report two cases of widespread retinal pigment epithelial clumping, irregularity, and atrophy after uncomplicated 25-gauge pars plana vitrectomy with brilliant blue-green-assisted internal limiting membrane peeling. METHODS: Retrospective analysis of 2 eyes of 2 patients who underwent 25-gauge pars plana vitrectomy for macular diseases (macular hole with retinal detachment and vitreomacular traction) was performed. Surgical notes and video recordings were reviewed to determine the surgical procedures performed and the duration of the surgery. Multimodal imaging analysis, including fundus photography, fundus autofluorescence imaging, and optical coherence tomography were performed to determine the pathological changes in the postoperative period. RESULTS: The mean age of the patients (all females) was 78 years. In all the patients, brilliant blue-green-assisted internal limiting membrane peeling was performed without any intraoperative complications. Four weeks after an uncomplicated surgery, the patients complained of progressive central visual disturbance and metamorphopsia. Retinal imaging demonstrated retinal pigment epithelial clumps and irregularity, which appeared as hyperautofluorescent on fundus autofluorescence, and widespread retinal pigment epithelial atrophy (hypoautofluorescent on fundus autofluorescence) in the posterior pole and peripapillary region, along with retinal and choroidal thinning. CONCLUSION: In uncomplicated vitrectomy consisting of brilliant blue-green-assisted internal limiting membrane peeling, a remote risk of widespread retinal pigment epithelial damage exists even with the use of modern endoilluminators and relatively short surgical duration. Retinal phototoxicity seems to be the primary cause; however, dye-related cytotoxicity or a combination of both cannot be ruled out.

PURPOSE: To study the efficacy of swept source optical coherence tomography angiography (SSOCTA) to longitudinally follow-up patients with extrafoveal polyps post-laser photocoagulation and anti-vascular endothelial growth factor injection. METHODS: Observational case series. Four patients diagnosed as polypoidal choroidal vasculopathy with extrafoveal polyps on multimodal imaging were followed up serially on SSOCT, en face and cross-sectional SSOCTA at a month and then 3 monthly for a year. Indocyanine green angiography was repeated at 4 months and 1 year. RESULTS: Anatomical regression of extrafoveal polyps was documented on a combination of en face and cross-sectional SSOCTA, 3 months post-laser photocoagulation and anti-vascular endothelial growth factor. Regression of polyps was maintained at the 12-month follow-up visit in all cases. Changes in branching vascular network morphology post-treatment were well-delineated on en face SSOCTA. Swept source optical coherence tomography angiography findings correlated well with the gold standard indocyanine green angiography. CONCLUSION: Swept source optical coherence tomography angiography is an effective noninvasive imaging modality to diagnose and longitudinally follow-up extrafoveal polyps postintervention. Laser photocoagulation with anti-vascular endothelial growth factor achieved regression of polyps in all cases and this was maintained over 12 months.

The peripheral retina is affected in a variety of retinal disorders. Traditional fundus cameras capture only a part of the fundus even when montaging techniques are used. Ultra-wide field imaging enables us to delve into the retinal periphery in greater detail. It not only facilitates assessing color images of the fundus, but also fluorescein angiography, indocyanine green angiography, fundus autofluorescence, and red and green free images. In this review, a literature search using the keywords "ultra-widefield imaging", "widefield imaging", and "peripheral retinal imaging" in English and non-English languages was done and the relevant articles were included. Ultra-wide field imaging has made new observations in the normal population as well as in eyes with retinal disorders including vascular diseases, degenerative diseases, uveitis, age-related macular degeneration, retinal and choroidal tumors and hereditary retinal dystrophies. This review aims to describe the utility of ultra-wide field imaging in various retinal disorders.

Purpose: To describe a bimanual technique, "tug of war" for managing anterior circumferential proliferative vitreoretinopathy (PVR) in eyes with recurrent retinal detachment (RRD). Methods: We retrospectively analyzed outcomes from eyes with RRD that underwent reattachment surgery using this maneuver and had a minimum of 6 months follow-up. A chandelier light was inserted for endo-illumination and the circumferential anterior PVR was tackled with two 25-gauge forceps stretching circumferential tractional membranes in opposite direction (tug of war) till they snapped. Results: Eleven eyes of 11 patients with a mean age of 38.2 ± 19.7 years underwent surgery. All eyes had advanced PVR of Grade C A Type 4 (Circumferential). The median duration of RD from the time of first surgery was 6 months (interquartile range = 3-8 months). The tug of war maneuver was successful in relieving the anterior retinal traction leading to retinal reattachment in all eyes without the need for relaxing retinotomies or retinectomies. Small iatrogenic retina tears occurred at the time of tug of war maneuver in 3 (27%) eyes at the site of maximum traction. The mean best-corrected visual acuity (BCVA) improved from 1.87 ± 0.2 logarithm of minimum angle of resolution (logMAR) to 1.3 ± 0.4 logMAR at 6-months follow-up (P = 0.04). Conclusion: The 'tug of war' maneuver is useful for relieving circumferential anterior traction and reattaching the retina in eyes with RRD without having to resort to large relaxing retinotomies or retinectomies.

PURPOSE: To evaluate the anatomical and functional outcome of patients with traumatic submacular hemorrhage (SMH). METHODS: A retrospective, interventional case series of patients presenting between January 2016 and April 2018 was carried out at 4 tertiary eye care centers of India. Medical records of the patients with a history of blunt trauma and SMH were retrospectively reviewed. The intervention done was any one of the following: pneumatic displacement with 0.3 ml of intravitreal gas [100% perfluoropropane (C3F8) gas], pneumatic displacement with intravitreal 0.3 ml of 100% C3F8 gas combined with 100 µg/0.1 ml of recombinant tissue plasminogen activator (r-tpa), pars plana vitrectomy (PPV) with subretinal r-tpa and gas tamponade. The primary outcome measures included change in visual and anatomical status. RESULTS: Twenty eyes of 20 patients with blunt trauma were analyzed. Thirteen patients had small size SMH, 5 patients had medium size SMH, and 2 patients had massive size SMH. Sixteen patients had a favorable functional outcome, and eighteen patients had favorable anatomical outcome. The size and duration of post-traumatic SMH did not significantly affect the anatomical (P = 0.123) or functional (P = 0.293) outcome in our study. The patients who presented with initial visual acuity of 6/60 or better showed better functional outcome, which was statistically significant (P = 0.007). CONCLUSION: Minimally non-invasive procedure including intravitreal r-tpa and gas appear to be effective in the displacement of post-traumatic SMH.

RESUMO
Direct perfluorocarbon liquid (PFCL)-silicone oil exchange presents its own set of challenges in the micro incision vitreous surgery era. We propose a simple bimanual technique to circumvent this problem. Thirteen eyes of patients with retinal detachment associated with giant retinal tears underwent vitrectomy followed by self-retaining endo illuminator (Chandelier) assisted direct PFCL-silicone exchange. No intra or postoperative complications related to the surgical technique were noted. All patients had attached retinas and satisfactory visual recovery at 6 months. Direct bimanual PFCL silicone oil exchange using a Chandelier seems to be a safe and effective technique.

PURPOSE: To evaluate the visual and anatomical outcomes and safety of bimanual microincision vitreous surgery for severe proliferative diabetic retinopathy. METHODS: Retrospective review of 315 eyes of 282 patients who underwent 23-gauge or 25-gauge pars plana vitrectomy with bimanual membrane dissection for diabetic tractional detachment from January 2007 to September 2016. Minimum follow-up was 3 months, and the average duration of follow-up was 23 months (range 3-100 months; median 15 months). Outcome measures were best-corrected visual acuity, anatomical success, and postoperative complications. RESULTS: Postoperatively, 84.3% of eyes improved (>2 lines), 10.5% were stable, and 5.4% worsened (>2 lines). Comparing gauges, two-line improvement was seen in 87.4% of 23-gauge eyes compared with 79.7% of 25-gauge eyes (P = 0.029). Mean peak best-corrected visual acuity improved from 20/930 (1.67 ± 0.63) preoperatively to 20/120 (0.78 ± 0.63) postoperatively (P < 0.001). Primary reattachment was achieved in 310 eyes (98.4%) and final reattachment in 312 eyes (99%). Recurrent vitreous hemorrhage was the commonest postoperative complication (18.4%). Lower incidence of recurrent vitreous hemorrhage was seen with 25 gauge (13.5%) compared with 23 gauge (22%, P = 0.038). Epiretinal membrane formation (7.9%), intractable glaucoma (2.5%), and endophthalmitis (0.6%) were some of the other postoperative complications. CONCLUSION: Sustained visual improvement, anatomical restoration, and low complication rates were obtained in complex situations with bimanual microincision vitreous surgery in a large series. Visual outcomes were poorer in older age group, tractional retinal detachments involving macula, and eyes with extensive membranes and with silicone oil as tamponade. Both 23-gauge and 25-gauge groups were comparable in relation to visual improvement, anatomical success, and intraoperative and postoperative complications.

PURPOSE: To assess the safety and efficacy of hybrid vitreous surgery combining active 23-G ports with a sutured 20-G 6-mm infusion cannula for performing vitrectomy in endophthalmitis and trauma. METHODS: This is a retrospective analysis of 10 eyes with endophthalmitis and 10 eyes with trauma requiring vitreous surgery, having corneal clarity suitable for vitrectomy and best-corrected visual acuity (BCVA) greater than or equal to light perception. All patients underwent hybrid 20/23-G vitrectomy. Intraoperative notes were analyzed for peroperative complications. The BCVA and retinal status at 3 months were analyzed. RESULTS: In the endophthalmitis group, patients ranged from 5 to 85 years of age and showed varied etiologies. Retinal detachment was present in 5 eyes, which received silicone oil tamponade. Mean preoperative logMAR visual acuity (VA) was 2.29 ± 0.45, which improved to 1.10 ± 0.72 at 3 months postoperatively (p<0.001). Trauma cases ranged from 21 to 75 years of age. Retinal detachment was present in 9 out of 10 eyes, all of which received silicone oil tamponade. Preoperative logMAR VA was 2.26 ± 0.71, which improved to 1.33 ± 0.50 postoperatively (p<0.001). At 3 months postsurgery, the retina was attached in all eyes in both groups. CONCLUSIONS: The longer sutured 20-G cannula was easier to visualize through fibrin, exudates, and hemorrhage and did not slip out or enter the suprachoroidal space in any of our cases. The 23-G active ports and vitrectomy cutter enhanced safety and efficacy. Hybrid vitrectomy enabled safe surgery in these difficult cases.

BACKGROUND: To profile the etiology, clinical features, visual and anatomical outcomes in eyes diagnosed with Enterococcus faecalis endophthalmitis. METHODS: A single (tertiary care) center, Retrospective interventional case series. Clinical and microbiological records of 26 consecutive eyes with culture positive E. faecalis endophthalmitis treated at a tertiary referral ophthalmic hospital in south India from 1st January 1995 to September 2007 were reviewed and analyzed. RESULTS: Of the twenty-six eyes, 12 were of postsurgical etiology, 11 cases were posttraumatic while 3 were of endogenous causes. Two eyes had an intraocular foreign body. Initial mean visual acuity was 3.19 logMAR (range: 0.77-4). All cases were treated with vitrectomy and intravitreal injections. Six cases developed retinal detachment after initial surgery, but only 30.7% eyes had a poor anatomical outcome (8 patients out of 26). All cases except one were sensitive to Vancomycin. Final mean visual acuity was 2.12 logMAR (range: 0.17-4). Paired 't' test showed statistically significant (P = 0.008) good visual outcome (better than or equal to 3/60). CONCLUSIONS: Surgery (12 of 26 eyes) and trauma (11 of 26 eyes) were the commonest causes of E. faecalis endophthalmitis. Our results indicate that early surgical intervention can lead to a good functional outcome despite the virulent nature of the organism. Since almost all the cases were sensitive to Vancomycin, it may be considered as a first line drug in the management of such eyes.

PURPOSE: To describe a case of macular infarction occurring after Enterococcus faecalis endophthalmitis in a patient who had undergone cataract surgery. METHODS: A 74-year-old woman who underwent uneventful phacoemulsification with intraocular lens implantation developed E. faecalis endophthalmitis on the second postoperative day. Management included repeated intravitreal antibiotic treatment, vitrectomy, and intraocular lens explantation. RESULTS: One week after intraocular inflammation subsided, macular infarction was noted clinically, which was confirmed by fundus fluorescein angiography. Visual acuity did not improve beyond 1/60 by Snellen chart testing. CONCLUSION: Posterior segment involvement, including optic atrophy, macular hole formation, and tractional retinal detachment, has been reported clinically as a complication of E. faecalis endophthalmitis. Macular infarction could be another sight-threatening complication of endophthalmitis due to E. faecalis.
RESUMO
BACKGROUND: To report the efficacy of combination photodynamic therapy and intravitreal ranibizumab for juxtafoveal, subretinal neovascular membrane (SRNVM) associated with type 2 idiopathic macular telangiectasia (IMT). METHODS: A 56-year-old woman with visual loss due to SRNVM secondary to IMT underwent primary treatment with a combination of photodynamic therapy (PDT) and intravitreal ranibizumab (0.5 mg). PDT was done as per the TAP study protocol, except that the laser spot size was same as the greatest linear diameter (GLD) of the lesion. This was followed by intravitreal ranibizumab (0.5 mg), 2 days later. RESULTS: At the 16-week follow-up, clinical examination revealed regression of the SRNVM, with no evidence of subretinal fluid, exudates or fresh hemorrhages. Visual acuity improved by 2 Snellen lines (from 6/36 to 6/18). Clinical findings were confirmed on FFA and OCT. At the last follow-up at 9 months, the SRNVM remained quiescent and visual acuity stable. No treatment-related adverse effects were noted. CONCLUSION: Combination therapy with PDT and intravitreal ranibizumab appears to be efficacious in the treatment of SRNVM associated with proliferative type 2 IMT.

PURPOSE: To evaluate serially the course of structural changes in the macula in recent onset branch retinal vein occlusion (BRVO), using optical coherence tomography (OCT). METHODS: Twenty eyes of patients at an institutional practice with recent onset BRVO were examined by OCT at presentation and at 3 and 6 months of onset of the occlusion. The macular thickness (MT) and the visual acuity were correlated with the macular perfusion status and analyzed statistically. RESULTS: The mean MT at presentation, 3 and 6 months was 398.9 +/- 98.6 mm, 346.8 +/- 84.8 mm and 341.3 +/- 95.3 mm, respectively. Three distinct anatomical patterns of structural changes were appreciated on OCT-serous retinal detachment (SRD) only in 15%, cystoid macular edema (CME) only in 40%, and a combined form with both SRD and CME in 45%. At 6 months while the non-ischemic group showed an average percentage decline of 26.8% in thickness, the ischemic group showed an increase of 19.2% (P < 0.01). CME resolved in 10 of 13 perfused (non-ischemic) maculae, but persisted in all seven ischemic cases. CONCLUSION: OCT delineates macular changes at a stage when fundus biomicroscopy and fluorescein angiography are not very informative. The anatomical cause for the increase in MT i.e., SRD and/or CME is also well delineated. Non-ischemic maculae show an early and more rapid decline in MT compared with ischemic occlusions. An increase in MT at 3 months on OCT in BRVO patients could be an indication of a possible ischemic course.
