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.

Abstract Purpose: To assess the vision-related quality of life (VR-QOL) following intravitreal ranibizumab (IVR) for branch retinal vein occlusion (BRVO) and to evaluate subscale items of the VR-QOL.Methods: In this prospective observational multicenter study, 38 patients who underwent IVR treatment for unilateral BRVO and 28 age-matched healthy subjects were chosen. The 25-item National Eye Institute Visual Function Questionnaire (VFQ-25) and best-corrected visual acuity (BCVA) were examined before and at 3, 6, and 12 months after treatment.Results: The VFQ-25 composite score and BCVA significantly improved from 3 to 12 months after IVR treatment (P < 0.05), such that there was no significant difference between the BRVO and control groups at 12 months. All subscales of the VFQ-25, except “general health,” significantly improved after treatment, while “near vision” and “mental health” were worse than those in healthy subjects (P < 0.05). Patients with superior BRVO had a lower “near vision” score than healthy subjects after treatment (P < 0.05). BCVA in the treated eye and fellow eye had no significant relationship with the VFQ-25 composite score before and after treatment.Conclusions: The VR-QOL of patients with BRVO improved with IVR treatment and was comparable to that of healthy subjects after 12 months. Superior BRVO particularly affected near vision for a low level.

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.

The Mean

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.
