An unusual case of branch retinal venous occlusion in a patient of uncomplicated pregnancy.

Abstract

Branch retinal venous occlusion (BRVO) is most commonly associated with hypertension and diabetes mellitus in all ages. Vasculitis associated with collagen vascular disorders and blood dyscrasias are more common in young ages. Pregnancy is a hypercoagulable state and is associated with thromboembolic disorders [1, 2]. There are reported cases of central retinal venous occlusion in pregnancy, but till date, there is no reported case of BRVO in uncomplicated pregnancy [3]. Eyes with arteriovenous crossings appear to be at risk for BRVO. Arterial compression of the vein is believed to be the main cause of BRVO.
