Abstract
Introduction
Venous obstructive disease of the retina is a common retinal vascular disorder, second only to diabetic retinopathy in incidence[1] causing significant visual morbidity affecting quality of life of patient. Incidence of CRVO is 0.8 per 1000 persons and 4.4 per 1000 persons for BRVO in general population[2].
The dramatic picture of obstructions of retinal veins was initially described as retinal apoplexy by Liebriech in 1854[3]. Leber[4] (1877) reported the first case of BRVO and called it as hemorrhagic retinitis. It was first established as a clinical entity due to thrombosis by Julius Von Michel. Koyanagi first reported the association between BRVO and AV-Crossings.
RVO most commonly affects the venous blood supply of entire retina [CRVO] or a quadrant drained by one of the branches [BRVO] less commonly superior or inferior half of retina alone is affected [HRVO]
