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.

The Mean

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.

Abstract Background: There is an ambiguity regarding the therapy of choice for patients with macular edema following branch retinal vein occlusion (BRVO). Aim: The purpose of the study was to compare the efficacy and safety of ranibizumab (3 injections 0.5 mg) versus ranibizumab (1 injection 0.5 mg) with laser photocoagulation (LP) versus dexamethamethasone intravitreal (IVT) implant (0.7 mg) with or without LP in patients with macular edema following BRVO. Materials and methods: 60 eyes of 60 patients were divided into 4 groups. Group 1 received IVT ranibizumab (3 injections 0.5 mg), Group 2 received IVT ranibizumab (1 injection 0.5 mg) + LP, Group 3 received dexamethasone IVT implant (0.7 mg), and Group 4 received dexamethasone IVT implant (0.7 mg) + LP. The endpoints were the difference in mean changes in best corrected visual acuity (BCVA), central macular thickness (CMT), and inter-group differences in contrast sensitivity (CS), retinal sensitivity (RS), and intraocular pressure (IOP). Results: BCVA gains in Group 1 (18.00±8.51) patients were significantly (p < 0.05) higher than patients in Groups 2 (10.00±10.26), 3 (9.50±9.60), and 4 (10.50±10.97), after 6 months of therapy. No significant inter-group variation was found in the CMT, CS, and RS. Conclusions: Ranibizumab (3 injections 0.5 mg) showed significantly higher BCVA gains at 6 months post-therapy. Improvements in the BCVA, CMT, CS, and RS were comparable initially in all the therapies.
