AIM: To observe changes in the best-corrected visual acuity (BCVA), central macular thickness (CMT), and central choroidal thickness (CCT) of patients with macular edema (ME) secondary to ischemic retinal vein occlusion (iRVO) following intravitreal Conbercept injection. METHODS: This retrospective study included 33 eyes from 33 patients who received intravitreal injections of Conbercept for ME secondary to iRVO. Treatments were performed on a 3+pro re nata (3+PRN) basis. All of the patients were examined by fundus fluorescein angiography and spectral domain optical coherence tomography at the first visit. Laser photocoagulation was performed in the nonperfusion area of the retina of all eyes after the first injection. BCVA, CMT, and CCT were observed before and after 6mo of treatment. The number of injections necessary to achieve improved vision was also noted. RESULTS: Following Conbercept treatment, the mean BCVA significantly improved from 0.81±0.39 at baseline to 0.41±0.25 and 0.43±0.29 logMAR in the third and sixth months, respectively (both P=0.000). The CMT of the patients at baseline was 556.75±98.57 μm; 304.78±68.53 and 306.85±76.77 μm 3 and 6mo after treatment, respectively (both P=0.000 vs baseline). The CCTs of the patients at baseline, 3 and 6mo after treatment were 304.63±57.83, 271.31±45.53, and 272.29±39.93 μm, respectively (P=0.026 and 0.035 vs baseline). No severe adverse event relevant to the therapy was noted, and the average number of injections delivered was 3.35. CONCLUSION: Intravitreal Conbercept injection combined with laser photocoagulation appears to be a safe and effective treatment for ME secondary to iRVO in the short-term.

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.

Retinal Vascular Disease

Retinal vein occlusion (RVO) is a retinal vascular disease that severely impairs the visual function of patients. Observing the changes of retinal blood vessels before and after treatment is of great significance for the prognostic evaluation of RVO. The rapid development and widespread use of fundus imaging technique, especially ultra-wide-angle fundus fluorescein angiography (UWFFA) and optical coherence tomography angiography (OCTA) have made our observation of the retinal blood vessels of RVO more comprehensive and meticulous. In this paper, we reviewed the latest research progress of UWFFA and OCTA in RVO.

Purpose. To compare the efficacy of intravitreal triamcinolone (IVT) and intravitreal bevacizumab (IVB), both combined with grid laser photocoagulation (GLP) for macular edema (ME) secondary to branch retinal vein occlusion (BRVO). Methods. Retrospective, comparative study. The newly diagnosed patients with ME secondary to BRVO who were treated with IVT and GLP or IVB and GLP were included. The main outcome measures were changed in the best corrected visual acuity (BCVA) and central retinal thickness (CRT) from the baseline to month 24. Results. Ninety-nine eyes of 99 patients were included. The change in BCVA was not statistically different in any time points between the two groups (P>0.05, for all). The change in CRT was not statistically different in any time points between the two groups (P>0.05, for all). The mean number of injections at month 24 was 2.38±1.06 in the IVT+GLP group and 4.17±1.30 in the IVB+GLP group (P=0.0001). The need for cataract surgery (P=0.01) and secondary glaucoma (P=0.03) occurrence were more common in IVT group. Conclusion. Both treatment modalities were effective in the treatment of ME secondary to BRVO. The number of injections was significantly lower in the IVT group than in the IVB group; however cataract and secondary glaucoma were more frequent in the IVT+GLP group than in the IVB+GLP group.

The Difference

Retinal vein occlusion is the second most common cause of blindness in retinal vascular disease after diabetic retinopathy and may lead to complications of macular edema. Bevacizumab is an influential treatment as an anti vascular endothelial growth factor (VEGF). This study aims to determine the difference of visual acuity and macular thickness before and after treatment of Bevacizumab. This is a quasi experimental study in patients with secondary macular edema retinal vein occlusion who meets the inclusion criteria. Visual acuity and macular thickness were evaluated after one month of treatment. This study was conducted for two months since May-June 2017 by collecting secondary data from medical record at SMEC Samarinda from January 2016 – June 2017. Data were analyzed using Wilcoxon. Sixteen eyes from 16 patients were diagnosed with macular edema secondary retinal vein occlusion given bevacizumab treatment. The mean visual acuity before therapy was 1.106 LogMAR ± 0.509 and increased to 0.889 logMAR ± 0.608 (p = 0.116) after treatment while the mean macular thickness before therapy was 504.06 μm ± 301.273 and decreased to 348.81 μm ± 181.17 (p = 0.017) after treatment. There was a significant effect on the decrease in macular thickness but no significant effect on visual acuity improvement in patients with macular edema secondary retinal vein occlusion at SMEC Samarinda.  Keywords: Retinal vein occlusion, macular edema, bevacizumab

Introduction: Central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO) caused sudden visual decrease that most often treatable. This paper aims to describe clinical characteristic and outcome using bevacizumab for macular edema caused by retinal vein occlusion in real-life practice. Methods: This retrospective study included 91 treatment-naïve eyes with macular edema due to CRVO (55 eyes) and BRVO (36 eyes), who were treated with intravitreal bevacizumab (IVB) in pro re nata (PRN) regimen. Best corrected visual acuity (BCVA) and central macular thickness (CMT) before and after treatment were evaluated. Result: The mean age of patients was 60.3 + 11.2 years for CRVO and 55.7 + 8.2 years for BRVO. The mean baseline BCVA in the CRVO group was 1.41 + 0.55 logMAR. There was statistically significant improvement in BCVA after intravitreal bevacizumab compared to baseline (p < 0.001) in CRVO and BRVO group. Twenty six (47.3%) eyes with CRVO had BCVA > 1.0 logMAR (Snellen 20/200) at the last follow-up. In the BRVO group, the mean baseline BCVA was 0.93 + 0.48 logMAR. At the end of the follow up, 19 eyes (52.8%) with BRVO had BCVA > 0.3 logMAR (Snellen 20/40). There was also statistically significant improvement in CMT between all time points and baseline (p < 0.001) in both groups. At the end of the follow up, 26 (47.3%) eyes with CRVO and 25 eyes (69.4%) in BRVO group presented resolution of macular edema (CMT < 300). Conclusion: Intravitreal bevacizumab resulted in significant anatomical and functional improvement in macular edema associated with CRVO and BRVO, although outcome in CRVO group was sub-optimal.
