To study early and late effect of intravitreal injection Ranibizumab on Cystoid Macular Edema(CME) due to Branch Retinal Vein Occlusion (BRVO)

Abstract

Objective: To study early and late effect of intravitreal injection Ranibizumab on Cystoid Macular Edema(CME) because of Branch Retinal Vein Occlusion (BRVO). Materials and Methods: This Study included 25 Patients (age group≥18 year) with cystoid macular edema because of branch retinal vein occlusion attending to department of ophthalmology Nehru Chikitsalaya, B.R.D. Medical college, Gorakhpur. An observational study has been concluded in which early and late effect of intravitreal injection Ranibizumab on cystoid macular edema because of branch retinal vein occlusion. Result: The mean age group being 58.53 year of total 25 patients with 13 male and 12 female patients with no dropout throughout the study. In 1 month of post injecton observation, 10 (40%) patients who presented within 1 month of onset of BRVO showed more gain in visual acuity and more reduction in central macular thickness (CMT) as compare to 15 (60%) patients who presented after 1 month of onset of BRVO. Conclusion: Intravitreal Ranibizumab is more effective in patients presented early than late in improving best corrected visual acuity ( BCVA) and decreasing CMT. © This is an open access article distributed under the terms of the Creative Commons Attribution License (https://creativecommons.org/licenses/by/4.0/) which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.
