Abstract Background Macular edema secondary to retinal vein occlusion (RVO) is an important cause of loss of vision. Intravitreal injections (IVI) of anti-vascular endothelial growth factor (VEGF) are the standard of care in this disease, as shown in numerous randomized controlled trials. The purpose of this study was to study the efficacy and safety of ranibizumab, an anti-VEGF agent, in the real-world setting. Methods This was 48 weeks, open-label, prospective, multicentre, observational study. Patients diagnosed with ME secondary to RVO were treated with IVI of Ranibizumab 0.5 mg in real-world conditions. Efficacy was measured by improvement seen in best-corrected visual acuity (BCVA) in terms of Early Treatment of Diabetic Retinopathy Study (ETDRS) Letter Scores and change in central retinal thickness (CRT) measured by optical coherence tomography. Results One hundred eyes of 100 patients (79 with branch retinal vein occlusion and 21 with central retinal vein occlusion) were recruited in the study. The mean (standard deviation, SD) BCVA was 52.8 (21.99) letters at baseline and 62.3 (24.40) letters at week 48. From baseline, there was a significant improvement in BCVA by 7.7 letters (p = 0.001) at 48 weeks. The mean (SD) of CRT was 479.9 (216.25) μm at baseline and it decreased significantly to 284.9 (171.35) μm at week 48 (p < 0.001). During the study period, the average number of intravitreal injections was 3.5 per patient. There was no report of endophthalmitis in any eye. Conclusions Ranibizumab is well tolerated and effective in treating macular edema secondary to RVO in real-world clinical settings. However, there is under-treatment compared to controlled clinical trials, and the gain in vision is sub-optimal with under-treatment.

Purpose. To report the long-term visual and anatomic outcomes of intravitreal injections for macular edema (ME) secondary to retinal vein occlusion (RVO) in a real-life clinical setting. Design. Retrospective interventional case series. Methods. A total of 223 consecutive eyes with ME secondary to RVO, treated with the first three intravitreal Ranibizumab or dexamethasone injections between August 2008 and September 2018, were enrolled in the study. Subsequent retreatment was guided by best-corrected visual acuity (BCVA) and central macular thickness (CMT) measurements, aimed at achieving macular fluid regression and BCVA stability. BCVA and CMT were recorded at baseline and at subsequent annual time points. The mean number of injections administered each year and the incidence of adverse events were recorded. Results. The mean BCVA and CMT at baseline were 0.79 logMar (SD 0.71) and 615.7 μm (SD 257.5), respectively. The mean follow-up (FU) period was 47.8 months (min 12–max 120). At 12 months, the mean BCVA and CMT had significantly improved to 0.62 logMar (SD 0.68; p<0.0001) and 401.04 μm (SD 183.8; p<0.0001). Improvements remained significant at the final FU visit. Eyes with BRVO and nonischemic RVO showed significantly better visual outcomes when compared to eyes with CRVO and ischemic RVO, over the entire FU period. An average of 4.08 (SD 2.1) Ranibizumab and 1.5 (SD 0.6) Ozurdex injections were administered over the first 12 months. The number of injections decreased thereafter progressively. One eye with CRVO developed endophthalmitis and one with BRVO developed an intraocular pressure increase that was refractory to topical medications and ultimately treated with trabeculectomy. Conclusion. Intravitreal Ranibizumab and/or dexamethasone injections were found to be effective at inducing a long-lasting improvement of BCVA and CMT in a real-life clinical setting. A safety profile similar to that already well-established in Ranibizumab and dexamethasone treatment was observed, as well as a steady decrease in the number of intraocular injections required. The results support intravitreal treatments for BRVO and CRVO in patient populations with similar characteristics in similar settings.

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.

Introduction. This investigation was focused on the post-RVO (retinal vein occlusion) macular edema treatment in cases with peripheral retinal ischemia, and on methods to estimate the ischemic area. Aim. To develop an examination and treatment algorithm for patients with chronic macular edema due to ischemic RVO. Material and methods. A prospective non-randomized study included 250 patients with RVO, the mean follow-up was 24.5 ± 6.5 months. Results. The drop-out of retinal capillary perfusion was detected in 175 patients (70 %). Peripheral ischemia was found in 125 cases, that is in 50% of all RVO patients and 71.4 % of all patients with ischemia. The mean number of ranibizumab injections performed after retinal photocoagulation was 2.9 ± 1.4. Patients treated with ranibizumab monotherapy for 24 months received 10.6 ± 2.5 intravitreal injections. Conclusions. The combination of ranibizumab intravitreal injections with retinal photocoagulation in the capillary non-perfusion areas can significantly reduce the number of injections and reduce the amount of neovascular complications.

Abstract We evaluated whether the reduction of macular vessel density was correlated with the number of intravitreal injections of anti-vascular endothelial growth factor (VEGF) agents in eyes with a branch retinal vein occlusion (BRVO). The mean vessel density was determined by optical coherence tomography angiography in 29 eyes with macular edema associated with a BRVO. Our results showed that the mean vessel density in the group that had a resolution of the macular edema after one anti-VEGF injection was significantly higher than group that had a recurrence of the macular edema (P = 0.028). Single regression analysis showed that the number of intravitreal injections was significantly correlated with the reduction of the modified vessel density (r = −0.421, P = 0.023) and systemic hypertension (r = 0.377, P = 0.044). Multiple stepwise regression analysis showed that the reduction of the modified vessel density (β = −0.442, P = 0.009) and hypertension (β = 0.403, P = 0.016) were independent factors associated with the number of intravitreal injections. We conclude that the vessel density reduction can be used to predict whether recurrences of the macular edema will develop after the initial anti-VEGF injection in eyes with macular edema associated with a BRVO.

Abstract Objective To evaluate the effectiveness, treatment patterns and long-term safety of ranibizumab 0.5 mg in treatment-naïve patients with central retinal vein occlusion (CRVO) in a real-world setting. Methods LUMINOUS, a 5-year, global, prospective, multicentre, multi-indication, observational, open-label study, recruited treatment naïve or prior treated patients who were treated as per the local ranibizumab label. Here, we report the mean change in visual acuity (VA; Early Treatment Diabetic Retinopathy Study [ETDRS] letters), treatment exposure over year (Y) 1 and 5-year safety in treatment-naïve CRVO patients. Results At baseline, the mean age of treatment-naïve CRVO patients (n = 327) was 68.9 years, with a mean (Standard deviation [SD]) VA of 40.6 (23.9) letters. At Y1, patients (n = 144) had a mean (SD) VA gain from baseline of 10.8 (19.66) letters, with a mean (SD) of 5.4 (2.65) ranibizumab injections. Patients demonstrated mean (SD) VA gains of 2.7 (19.35), 11.6 (20.56), 13.9 (18.08), 11.1 (18.46) and 8.2 (24.86) letters with 1, 2–3, 4–5, 6–8 and >8 ranibizumab injections, respectively. Mean (SD) VA gains at Y1 in patients receiving loading (67.4%) and no loading dose (32.6%) was 11.9 (20.42) and 8.4 (17.99) letters, respectively. Over five years, the incidence of ocular/non-ocular adverse events (AEs) and serious AEs was 11.3%/8.6% and 1.2%/6.7%, respectively. Conclusions These results demonstrate the effectiveness of ranibizumab in treatment-naïve CRVO patients at Y1 with clinically meaningful VA gains and no new safety findings over five years. These findings may help inform routine practice and enable better clinical management to achieve optimal visual outcomes.

AbstractTo evaluate the effects of intravitreal ranibizumab injection (IVR) on metamorphopsia in patients with branch retinal vein occlusion (BRVO), and to assess the relationship between metamorphopsia and inner retinal microstructure and other factors. Thirty-three treatment-naïve eyes of 33 patients with macular edema caused by BRVO with at least 12 months of follow-up were included. The degree of metamorphopsia was quantified using the M-CHARTS. Retinal microstructure was assessed with spectral-domain optical coherence tomography. Disorganization of the retinal inner layers (DRIL) at the first month after resolution of the macular edema (early DRIL) and at 12 months after treatment (after DRIL) was studied. Central retinal thickness (CRT), and status of the external limiting membrane as well as ellipsoid zone were also evaluated. IVR treatment significantly improved best-corrected visual acuity (BCVA) and CRT, but the mean metamorphopsia score did not improve even after 12 months. Post-treatment metamorphopsia scores showed a significant correlation with pre-treatment metamorphopsia scores (P < 0.005), the extent of early DRIL (P < 0.05) and after DRIL (P < 0.05), and the number of injections (P < 0.05). Multivariate analysis revealed that the post-treatment mean metamorphopsia score was significantly correlated with the pre-treatment mean metamorphopsia score (P < 0.05). IVR treatment significantly improved BCVA and CRT, but not metamorphopsia. Post-treatment metamorphopsia scores were significantly associated with pre-treatment metamorphopsia scores, the extent of DRIL, and the number of injections. Prognostic factor of metamorphopsia was the degree of pre-treatment metamorphopsia.

Purpose: To study the effects of combined intravitreal injections of bevacizumab (IVB) and triamcinolone acetonide (IVTA) in patients with non-resolving macular edema (ME) secondary to Branch Retinal Vein Occlusion (BRVO). Methods: In a prospective observational study, 50 pseudophakic eyes of BRVO patients with non-resolving central macular edema who had received more than 3 doses of IVB previously were injected with combination therapy of 1.25 mg/0.05 ml IVB and 4 mg of IVTA and followed up for 6 months with best corrected visual acuity(BCVA), intraocular pressure(IOP) and central macular thickness(CMT) Results: The mean BCVA was logMAR 0.75±0.25 at baseline and 0.65±0.15, 0.48±0.20, and 0.22±0.25 at 6weeks, 3 months and 6 months respectively. Mean CMT at baseline was 668.32±254.66 and 434.43±99.55, 243.22±58.92, and 220.83±42.60 at 6 weeks, 3 months and 6 months respectively. Baseline IOP measured was 16.5±3.1 mmHg which progressed to 19.6±3.4mmHg and 21.4±2.8mmHg at 6 weeks and 3 months respectively and decreased to 17.3±2.2 at 6 months. The most common adverse effect seen was increase in IOP in 24(48%)patients, out of which 3(6%) patients needed to start anti-glaucoma medication (AGM). 3(6%) patients had sub-conjunctival hemorrhage(SCH). Conclusion: The prolonged therapeutic effects of combination therapy leads to outstanding anatomical and visual outcome in non resolving ME due to BRVO, with fewer doses and thus fewer adverse effects.
