Factors Associated With Short-Term Visual Outcome in Patients With Retinal Vein Occlusion: A Prospective Observational Study at a Tertiary Care Center in Eastern India

BackgroundRetinal vein occlusion (RVO) is an important retinal vascular disorder and a significant cause of visual impairment worldwide.Although advances in treatment have improved the management of RVO, visual recovery remains variable among patients.Identifying demographic, systemic, and ocular factors associated with visual prognosis may help in clinical assessment, counseling, and follow-up planning.The present study evaluated demographic, systemic, and ocular factors associated with visual outcome at 60 days in patients with established RVO. MethodsThis prospective observational study was conducted at the Regional Institute of Ophthalmology, Rajendra Institute of Medical Sciences, Ranchi, following institutional ethics approval.A total of 60 patients with confirmed RVO aged 41-60 years comprised the enrolled cohort.Participants underwent detailed ophthalmic evaluation, including best-corrected visual acuity (BCVA), fundus examination, optical coherence tomography, fundus fluorescein angiography, and relevant laboratory investigations.Patients were followed for 60 days, with clinical assessments scheduled on days 1, 7, 21, 45, and 60.The primary visual outcome was final BCVA at 60-day follow-up, categorized as good (BCVA better than 6/18) or poor (BCVA of 6/18 or worse).Data were analyzed using SPSS (IBM Corp., Armonk, NY).Appropriate parametric and nonparametric categorical analyses, including independent-samples t-tests, chi-square tests, Fisher's exact test, paired ttest, and multivariable logistic regression, were performed.A two-sided p-value of <0.05 was considered statistically significant.
