Epidemiological Study of Retinal Vein Occlusion and Various risk factors in Tertiary Centre in Garhwal Himalayan Region

Abstract

INTRODUCTION 
Occlusive occlusion disorders together form the most common cause of visual impairment. Before a 
disease can be managed, it is essential to understand its natural history in order to assess the likely 
effectiveness of any intervention. 
Retinal vein occlusion (RVO) is the most common retinal vascular occlusive disorder and is usually 
associated with variable visual loss. RVO is the second most common retinal vascular disease after 
diabetic retinopathy. Affected 16.4 million adults worldwide. Early recognition is important because 
complications cause significant ocular morbidity.
