Introduction: Vitreous hemorrhage is one of the most common differential diagnoses of sudden painless decrease in vision. Objective: To find out the etiology of vitreous hemorrhage in cases of vitreous hemorrhage at a tertiary eye centre in Nepal. Materials and methods: This was a hospital-based cross-sectional study done over a period of one-and-a-half years. One hundred and one subjects with vitreous hemorrhage were evaluated in detail to establish the etiology. Statistics: The mean value and standard deviation were calculated. The data were analyzed using microsoft excel and SPSS 11.5 program. Results: A total of 122 eyes of 101 patients were evaluated. The mean age was 41.90 (± 21.50) years with a range of 2 months to 84 years. Male were 73 %. Bilateral involvement was found in 20.8 %. Proliferative diabetic retinopathy, retinal vasculitis, branch retinal vein occlusion, rhegmatogenous retinal detachment together with ocular trauma constituted the etilogoy of vitreous hemorrhage in more than 75 % of patients. Conclusion: Proliferative diabetic retinopathy, retinal vasculitis and branch retinal vein occlusion are the most common causes of vitreous hemorrhage in adults whereas in children trauma is the commonest cause.

Purpose: This work aims to investigate real-world treatment patterns and outcomes in eyes with branch retinal vein occlusion in the antivascular endothelial growth factor (anti-VEGF) era. Methods: A retrospective, nonrandomized, comparative study was conducted on eyes diagnosed with branch retinal vein occlusion at a single tertiary center between 2009 and 2017. Medical history, treatment patterns, and visual acuity outcomes were examined. Subanalysis was performed for eyes that met the eligibility criteria for the BRAVO (Ranibizumab for the Treatment of Macular Edema Following Branch Retinal Vein Occlusion) trial. Results: A total of 315 eyes were included, of which 244 were treatment naive. In all eyes, the most common first treatment was the following: intravitreal bevacizumab (38.4%), aflibercept (15.1%), ranibizumab (8.1%), sectoral scatter laser (6.2%), and triamcinolone (3.1%). At 1 year, treatment-naive eyes had received an average of 2.43 anti-VEGF injections. During follow-up, treatment-naive eyes gained an average of 0.21 Early Treatment Diabetic Retinopathy Study lines. Forty eyes that met BRAVO trial criteria received an average of 5.05 anti-VEGF injections in the first year and gained an average of 1.83 Early Treatment Diabetic Retinopathy Study lines. Conclusions: This real-world cohort received fewer anti-VEGF injections at year 1 and experienced less improvement in visual acuity during the course of treatment than clinical trial participants. Trial-eligible patients received more injections and had greater visual gains than those who would not have been eligible for the trial.

Abstract Purpose To investigate the long-term surgical outcomes after treatment with pars plana vitrectomy (PPV) combined with photocoagulation in different severities of branch retinal vein occlusion (BRVO) with vitreous hemorrhage (VH) in order to propose a new grading system. Methods We retrospectively reviewed the medical records of 117 eyes of 117 patients who underwent PPV for VH associated with BRVO and who were followed up for at least 12 months. Preoperative best-corrected visual acuity (BCVA), surgical intervention, final BCVA, and central foveal thickness (CFT) were evaluated using optical coherence tomography. We proposed a system to grade BRVO with VH from Grade I to Grade III with increasing severity: Grade I,pure persistent VH; Grade II,VH with epiretinal membrane (EM) (Grade IIa,VH with EM without macular involvement; Grade IIb,VH with EM with macular involvement); and Grade III,VH with tractive retinal detachment. Different surgical methods were appliedaccording to the different retinal conditions. Results BCVA significantly improved at final follow-up in all groups. There was no significant difference among the four groups in terms of preoperative BCVA, final BCVA,CFT,or the number of patients whose macular edema recurred after surgery (p>0.05), but there was a significant difference in vision improvement(p<0.05). Vision improvement in the Grade IIb group was significantly worse than in the Grade I group(p=0.006) and in the Grade IIa group(p=0.046). The percentage of patients in the Grade I, Grade IIa, Grade IIb, and Grade III groups needing further laser treatment after surgery was 0%, 8.3%, 16.3%, and 23.5%, respectively (p<0.05). Conclusion We proposed a new grading system for BRVO treated with PPV. Vitrectomy is a safe and effective treatment for BRVO with VH. Visual acuity improvement was significantly worse when the EM had macular involvement (Grade IIb).

Introduction: Vitreous hemorrhage is one of the most common diseases presenting to emergency department and leading cause of painless vision loss. Objectives: To determine the profile of vitreous hemorrhage in patients presented to Outpatient Department (OPD) and emergency Department of Tilganga Institute of Ophthalmology (TIO). Materials and methods: This is a hospital based observational non interventional descriptive study. Total 198 patients were enrolled who visited OPD and Emergency department of TIO from August 1st 2012 to July 30th 2013. Result: Total 198 patients (201 eyes) were enrolled for the study, out of which 144 were male and 54 females. 195 were unilateral and 3 bilateral cases. Most common age group of presentation of vitreous hemorrhage was 51-60 years (24.75%). Most common presenting complaint was sudden onset of decreased vision (95%). Most common etiology of vitreous hemorrhage was branch retinal vein occlusion (22.38%). Among the total subjects, 57.7% of the patient were managed with medical therapy, 35.8% surgically and 6.47 % with combined medical and surgical treatment. Conclusion: Branch retinal vein occlusion (BRVO) is the most common cause of vitreous hemorrhage. Diabetes and hypertension are the most commonly associated systemic illnesses.

Purpose: To assess the efficacy and safety of a modified treat-and-extend (mTAE) regimen of aflibercept for macular edema (ME) due to branch retinal vein occlusion (BRVO). Methods: This prospective multicentre intervention study evaluated 50 eyes of 50 patients enrolled from October 2016 to September 2017. The patients received intravitreal aflibercept (IVA) injections on an mTAE regimen for a total of 12 months. The main outcome measures were best-corrected visual acuity (BCVA) and central subfield thickness (CST) at 12 months. Results: The baseline BCVA and CST were 0.33 (0.27) and 488 (171) µm (mean (standard deviation)), respectively. The BCVA and CST were significantly improved at month 12 (0.067 (0.19) LogMAR and 295 (110) µm; both p < 0.0001, paired t-test). The mean number of clinic visits and IVA injections was 6.71 (1.41) and 4.26 (0.71), respectively. The time to first recurrence from the first injection was most frequently 3 months. Conclusion: The mTAE regimen of IVA injections for ME due to BRVO effectively improved BCVA and reduced CST, and thus might be an effective therapy to reduce the number of injections and visits.

Purpose. To evaluate the neutrophil/lymphocyte ratio (NLR) and the platelet/lymphocyte ratio(PLR) value in the development of branch retinal vein occlusion (BRVO)patients. Methods. 81 patients with BRVO and 81 age and sex-matched subjects were recruited as the control group. The BRVO diagnosis was confirmed under comprehensive ophthalmologic examinations. NLR and PLR parameters obtained from peripheral blood were recorded. Results. Both the mean NLR and PLR was significantly higher in the BRVO group compared with the control group (p < 0.001). In ROC analysis, the AUC for NLR was 0.82, and NLR of >2.48 predicted BRVO with a sensitivity of 58% and specificity of 98%. The AUC for PLR was 0.78, and PLR of >110.2 predicted BRVO with a sensitivity of 72% and specificity of 72%. Conclusion. The current study demonstrated that BRVO patients had increased NLR and PLR levels compared with control subjects. The NLR and PLR may be used as independent predictors for identifying risk for the development of BRVO.

Purpose: Dexamethasone intravitreal implant and intravitreal ranibizumab are indicated for the treatment of macular edema secondary to retinal vein occlusion. This non-inferiority study compared dexamethasone with ranibizumab in patients with branch retinal vein occlusion. Methods: In this randomized, 12-month head-to-head comparison, subjects with branch retinal vein occlusion were assigned to dexamethasone 0.7 mg at day 1 and month 5 with the option of retreatment at month 10 or 11, or ranibizumab 0.5 mg at day 1 and monthly through month 5 with subsequent as-needed injections at month 6–month 11. The primary efficacy outcome was the mean change from baseline in best-corrected visual acuity at month 12; secondary outcomes included average change in best-corrected visual acuity, proportion of eyes with ≥10- and ≥15-letter gain/loss, change in central retinal thickness, and change in Vision Functioning Questionnaire-25 score. Results: In all, 307 of a planned 400 patients were enrolled in the study and received (mean) 2.5 dexamethasone injections (n = 154) and 8.0 ranibizumab injections (n = 153) over 12 months. The mean change from baseline in best-corrected visual acuity at month 12 was 7.4 letters for dexamethasone versus 17.4 letters for ranibizumab (least-squares mean difference (dexamethasone minus ranibizumab), −10.1 letters; 95% confidence interval, −12.9, −7.2; p = 0.0006). Conclusion: Dexamethasone and ranibizumab improved best-corrected visual acuity and anatomical outcomes; however, dexamethasone did not show non-inferiority to ranibizumab in this under-powered study. Dexamethasone was associated with an increased risk of intraocular pressure elevation and cataract progression, but a lower injection burden, compared to ranibizumab.

Purpose: To compare the effects of intravitreal ranibizumab injection and yellow (577 nm) subthreshold micropulse laser treatment in patients with macular edema following non-ischemic branch retinal vein occlusion. Methods: The medical records of 51 patients who underwent intravitreal ranibizumab (0.5 mg) injection or subthreshold micropulse laser for the treatment of macular edema due to branch retinal vein occlusion were retrospectively reviewed. Subthreshold micropulse laser was administered with a 10% duty cycle, 100 μm spot diameter, 200 ms exposure time. The patients received an injection or laser treatment at baseline and were, then, retreated as needed and were followed for 12 months. The mean best corrected visual acuity changes over the follow-up and the decrease in the mean central macular thickness were evaluated. Results: A total of 27 and 24 patients were assigned to intravitreal ranibizumab and subthreshold micropulse laser subgroups, respectively. The mean number of treatment was 3.81 of intravitreal ranibizumab group and 1.5 of subthreshold micropulse laser group (p < 0.05). The subgroups were similar with regard to the mean score of best corrected visual acuity at baseline, at 1, 6, and 12 months (p > 0.05). The decrease in the mean central macular thickness was significant in both intravitreal ranibizumab and subthreshold micropulse laser groups at 1, 6, and 12 months than that of values at baseline (p < 0.05). No new ocular or systemic adverse events were observed. Conclusion: Our study results showed that intravitreal ranibizumab or yellow subthreshold micropulse laser treatment for macular edema due to branch retinal vein occlusion was not found to be superior to each other for reducing macular thickness and increasing visual acuity for 1-year period. Based on these results, subthreshold micropulse laser may be a useful alternative approach in the treatment of macular edema secondary to branch retinal vein occlusion.

AimTo determine whether there are factors that can predict the frequency of recurrences of macular oedema associated with branch retinal vein occlusion (BRVO).MethodsWe reviewed the medical records of 31 eyes with treatment-naïve macular oedema associated with BRVO. All eyes received an intravitreal ranibizumab (IVR) injection and were followed with a pro re nata protocol for at least 12 months. A reinjection of ranibizmab was performed when the central foveal thickness was ≥300 µm. At 1 month after IVR injection, the macular vessel reduction was calculated by comparing the vessel density in the optical coherence tomography angiography in the BRVO involved half to that in the non-involved half.ResultsThe mean visual acuity improved from 0.35±0.27 logarithm of the minimal angle of resolution (logMAR) units (20/45; Snellen) at initial visit to 0.06±0.15 logMAR units (20/23) at 12 months (p<0.0001). During 12 months, the mean number of IVR injections was 3.8±1.8. Multivariate regression analysis showed that a greater macular vessel reduction at 1 month after initial IVR injection was significantly a negative predictor of frequency of IVR injections (β=−0.5065, p=0.0082). The visual acuity and the central foveal thickness at the initial visit or at 1 month after initial IVR injection were not predictive factors for frequency of IVR injections.ConclusionsPatients with BRVO with a large macular vessel reduction at 1 month after an initial IVR injection have fewer recurrences and thus lower frequency of IVR injections during 12 months.

AimsTo detect collateral vessels using optical coherence tomography angiography (OCTA) in eyes with branch retinal vein occlusion (BRVO) and to investigate the associations with visual outcomes and macular oedema.MethodsEyes with macular oedema secondary to BRVO that underwent OCTA at baseline and were followed up for more than 6 months were enrolled. The presence of collaterals, whether the collaterals were leaky or not, and the associations with visual outcomes and macular oedema were investigated.ResultsTwenty-eight eyes of 28 patients (8 men and 20 women; mean age, 68 years) were enrolled. Collaterals were detected in 23 eyes (82%) and already existed at the initial visit. Collaterals were more frequently detected in eyes with major BRVO or ischaemic type. One-third of the collaterals were leaky and all of the leaky collaterals had microaneurysms (MAs) inside. Macular oedema in eyes with collaterals was more quickly and frequently resolved than that in eyes without collaterals, but there were no significant differences. Collateral vessel formation did not seem to impact on visual outcomes, but the mean baseline central retinal thickness (CRT) was significantly higher in eyes with collaterals, and the mean CRT reduction at 6 months after treatments was significantly greater than in eyes without collaterals.ConclusionsThese results suggest that collateral vessels are formed at the acute phase in eyes with BRVO. In addition, the presence of collaterals might be associated with absorption of macular oedema, but MAs formed in collaterals sometimes can cause macular oedema.
