ABSTRACT

Retinal vein occlusion (RVO) is a common cause of vision loss in older individuals, and the second most common retinal vascular disease after diabetic retinopathy.[1] It is of 2 distinct types, in central RVO (CRVO), occlusion is at or proximal to lamina cribrosa of optic nerve, where central retinal vein exits eye.[2] CRVO is further divided into perfused (non-ischemic) and non-perfused (ischemic).[3] Bilateral involvement is rare and usually associated with systemic vascular or hematologic disorders. We report a unique case of bilateral CRVO presenting with asynchronous onset – one eye exhibiting sequelae of an old occlusion, and the other with acute findings. This report highlights the importance of systemic evaluation, vigilant follow-up, and individualized management in bilateral, time-lagged presentations.
