Abstract

Background: The purpose of this study was to compare the efficacy of intravitreal ranibizumab in the treatment of macular edema due to branch retinal vein occlusions (BRVO) with and without serous macular neuroretinal detachment (SMD). Methods: Forty-nine eyes of 49 patients with macular edema due to branch retinal vein occlusion (22 with SMD and 27 without SMD) were included in this prospective, parallel-group, comparative study. Intravitreal injection of ranibizumab was administered at baseline. Thereafter patients were followed monthly and further injections were performed in the presence of persistence or recurrence of macular thickening. Flattening of the macula was considered success. At the last visit, best-corrected visual acuity (BCVA), and spectral-domain optical coherence tomography (SD-OCT) quantitative parameters (central subfield thickness, cube volume, average cube thickness) were compared between groups. Results: In patients with SMD, BCVA and all the SD-OCT quantitative parameters improved significantly after a mean number of 5.0 ranibizumab intravitreal injections through a median follow-up of 12.5 months (range, 7-34). In patients without SMD, all the variables analyzed improved significantly except for the cube volume, after a mean number of 4.3 ranibizumab intravitreal injections through a median follow-up of 10.4 months (range, 6.5-40.2). The numbers of injections were similar in both groups. The final BCVA was better in patients without SMD at baseline but without significant differences in the SD-OCT parameters between groups. Conclusions: The presence of SMD may be a baseline predictive factor for ranibizumab treatment outcomes in BRVO patients, with no influence in the number of treatments needed between patients with or without SMD at baseline. Further studies are needed in order to confirm the role of SMD as an independent predicitive factor in cases of BRVO.
