Takayasu's arteritis: a unique ophthalmic presentation with CRAO and BRVO

A unique case of sequential occurrence of central retinal artery occlusion (CRAO) and superotemporal branch retinal vein occlusion (ST-BRVO) in a patient of Takayasu's arteritis is described. An 18-year-old man was diagnosed as left eye CRAO on his initial presentation and was subjected to a complete cardiovascular evaluation revealing findings diagnostic of Takayasu's arteritis. Patient was however lost to follow-up and presented 16 months later with ST-BRVO in the right eye. Multidisciplinary intervention and an appropriate ocular intervention led to complete recovery of vision in the right eye that was maintained until his last ophthalmic evaluation (2.5 years after the initial presentation). Though uncommon, small retinal vessel involvement can occur in Takayasu's arteritis as the inaugural feature. Hence, CRAO or branch retinal vein occlusion in a young patient, especially a male, mandates a thorough systemic evaluation and a high index of suspicion of Takayasu's arteritis to prevent vision threatening complications.
