Background. To determine the effectiveness of intravitreal ranibizumab (IVR) approach over 1-year follow-up in patients younger than 50 years old with central and branch retinal vein occlusion (RVO) complicated by macular edema (ME). Methods. Prospective, open-label case series. Patients initiating IVR injections from January 2015 to May 2017 were consecutively recruited. Each patient underwent monthly ophthalmic examination and structural OCT over 12 months. A single IVR injection was administered at baseline, followed by a PRN regimen. Outcome measures are best-corrected visual acuity (BCVA); central foveal thickness (CFT); number of IVR injections; subretinal fluid (SRF); epiretinal membrane; and outer retinal layer (ORL) status. Results. Thirty-eight patients (27 males) were included in the study. At follow-up, mean BCVA improved from 0.40±0.17 to 0.10±0.10 LogMAR in patients with central RVO and from 0.39±0.19 to 0.19±0.07 LogMAR in those with branch RVO, with 20 eyes gaining ≥3 ETDRS lines. In addition, mean CFT significantly decreased in both subgroups at the end of follow-up. All patients with SRF at baseline (9) disclosed complete resolution after 1 year. Likewise, ORL appeared reconstituted in most cases. At 12 months, 3.6±2.4 and 4.4±2.4 IVR injections were required for central and branch RVO, respectively, with only 5 eyes showing ME persistence. Conclusions. Our study indicates that IVR injections can be a valid therapeutic option in patients under 50 years of age with ME secondary to RVO.

Abstract Aim To evaluate the efficacy of ziv-aflibercept in Ghanaian patients with macular edema (ME) secondary to retinal vein occlusion (RVO). Methodology In this retrospective study, the medical records of patients with ME secondary to RVO who had been treated with intravitreal ziv-aflibercept (IVZ) (1.25 mg/0.05 ml), as part of routine clinical practice, on pro re nata basis with a minimum follow-up of 6 months were retrieved and analyzed. The main outcome measures are mean change in best-corrected visual acuity (BCVA) and central subfield foveal thickness (CSFT) measured on optical coherence tomography from baseline to 12 months post-IVZ, and ocular and systemic safety. Results Forty-three eyes were included in this study. Their mean age was 62.8 ± 11.9 years, 67.4% had at least 12-month duration of follow-up, 50% had primary open-angle glaucoma and 38 (88.4%) eyes were treatment naive. There was significant improvement in mean BCVA in LogMAR at 1 month post-initiation of IVZ (0.8 ± 0.5 vs. 1.1 ± 0.6), and visual improvement was maintained up to 12 months (p < 0.001). Eyes with ME following BRVO had better mean BCVA at baseline and on subsequent visits compared to eyes with CRVO/HRVO (p = 0.01). There was significant reduction in mean CSFT up to 12 months post-IVZ injection compared to baseline (p < 0.001). Ocular complications observed were consistent with complications associated with RVO. Conclusion We have observed significant improvement in functional and anatomic outcomes 12 months post-initiation of IVZ. There is the need to confirm long-term efficacy and safety of IVZ in a large prospective study.

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. Ischemic central retinal vein occlusion (CRVO) eyes are at high risk of developing neovascular glaucoma (NVG). Our purpose is to investigate the effect of anti-VEGF therapy for macular edema after CRVO on the development of neovascular glaucoma (NVG) in ischemic CRVO eyes.Methods. This is a retrospective case series of 44 eyes from 44 patients with CRVO treated with anti-VEGF therapy for macular edema. The primary outcome was the development of NVG.Results. Of the 44 eyes, 14 eyes had ischemic CRVO, and 30 eyes had nonischemic CRVO. Nonischemic eyes received a mean of 8.4 anti-VEGF doses, over mean follow-up of 24 months. One nonischemic eye (3.3%) developed NVD but not NVG. The 14 ischemic eyes received a mean of 5.6 anti-VEGF doses, with mean follow-up of 23 months. Of these 14 ischemic eyes, two eyes (14%) developed iris neovascularization and 3 eyes (21%) developed posterior neovascularization. Three of these 5 eyes with neovascularization progressed to NVG, at 19.7 months after symptom onset, on average.Conclusion. Anti-VEGF therapy for macular edema may delay, but does not prevent, the development of ocular NV in ischemic CRVO. Significant risk of NVG still exists for ischemic CRVO eyes.

Purpose. To evaluate the correlative factors of best-corrected visual acuity (BCVA) with intravitreal conbercept injection in macular edema secondary to branch retinal vein occlusion (BRVO). Methods. This is a self-controlled retrospective study. 35 eyes of 35 patients with macular edema secondary to BRVO were enrolled. After an initial intravitreal injection of conbercept (0.5 mg/0.05 ml) monthly up to 3 months, a pro re nata (PRN) strategy was adopted based on the increase in central foveal thickness (CFT). Data collected at various time points include BCVA, CFT, photoreceptor layer thickness (PLT), and outer nuclear layer thickness (ONLT) on optical coherence tomography. The correlation between CFT, PLT, ONLT, and BCVA before and after injections was analyzed. Results. Compared with baseline, in months 1, 3, and 6 after injection, the improvement of BCVA was 20.63, 22.94, and 21.06 ETDRS letters, respectively (F=195.843, P<0.01), and the decrease of CFT was 217.37 μm, 224.57 μm, and 224.06 μm, respectively (F=148.522, P<0.01). The PLT in months 1, 3, and 6 after therapy has significant improvement of 11.14 μm, 13.03 μm, and 13.49 μm (F=64.116, P<0.01), while the ONLT has a significant decrease of 225.29 μm, 237.66 μm, and 239.11 μm, respectively (F=145.231, P<0.01). The changes in the treatment group were significant in different periods. The mean number of injections was 3.26 ± 0.50 from baseline to month 6. Conclusions. Intravitreal injection of conbercept provides an effective treatment for macular edema due to BRVO. With six-month treatment, there were a positive correlation between BCVA and PLT (r=0.592, P<0.001), a negative correlation between BCVA and ONLT (r=−0.480, P=0.005), and no correlation between BCVA and CFT (P=0.506).

The Ranibizumab for Macular Edema following Branch Retinal Vein Occlusion (BRAVO) study was a 6-month, phase III, randomized, injection-controlled trial, with an additional 6 months of follow-up (total 12 months), to evaluate the safety and efficacy of intraocular injections of 0.3 mg and 0.5 mg ranibizumab (an anti–vascular endothelial growth factor [VEGF] agent) in patients with macular edema following branch retinal vein occlusion (BRVO). The study showed that intraocular injections of 0.3 mg or 0.5 mg ranibizumab provided rapid, effective treatment for macular edema following BRVO with low rates of ocular and nonocular adverse events. This study led to a paradigm shift toward anti-VEGF agents as the first-line treatment for macular edema secondary to BRVO.

Abstract Background: To evaluate the efficacy of intravitreal injection of conbercept (IVC) with or without laser photocoagulation for recurrent macular edema secondary to branch retinal vein occlusion (BRVO). Methods: 82 patients (82 eyes) with recurrent macular edema secondary to BRVO were collected. The central macular thickness (CMT) and best corrected visual acuity (BCVA) were recorded. Results: The BCVA in both groups was significantly superior to that before treatment (P<0.05). Compared with initial values, CMT was reduced significantly in both groups (P<0.05). But at 1 month to 6 month after treatment, there are no significant difference was observed between the two groups (P>0.05). In the combined therapy group for Hemispheric Retinal Vein Occlusion, we observed a lower number of reinjections during follow-up. Conclusion: Conbercept with or without retinal photocoagulation can effectively improve the visual acuity and reduce the CMT.

Branch retinal vein occlusion (BRVO) is a relatively prevalent cause of reduced vision primarily due to macular edema. Vascular endothelial growth factor (VEGF) is the major stimulator of excessive vascular leakage and also contributes to retinal hemorrhages and progressive retinal nonperfusion (RNP). Progressive RNP results in worsening of retinal ischemia further increasing levels of VEGF, resulting in a positive feedback loop for disease worsening over time. Aggressive early treatment with a specific antagonist of VEGF causes rapid improvement in edema and visual acuity, speeds resolution of hemorrhages, and stabilizes or improves RNP. Therefore, first-line treatment of acute BRVOs is monthly injections of an anti-VEGF agent for at least 6 months. After that, a period of monthly follow up with anti-VEGF treatment, only if there is recurrent edema, can be used to gauge persistent disease activity and the need for grid laser photocoagulation to diffuse leakage in the macula outside the foveal avascular zone. Following grid laser, another period of monthly follow up with anti-VEGF treatment only if there is recurrent edema provides a measure of persistent disease activity, and if frequent injections are still needed to control edema, the benefits and risks for switching to dexamethasone implants should be discussed with the patient.
