We present a case of a young Afro-Caribbean man who presented with sudden unilateral loss of vision due to central retinal artery occlusion. He was a cocaine and cannabis abuser for 6 years. Acute central retinal artery occlusion at such a young age is unusual. We discuss the possible pathogenesis and treatment options for acute retinal artery occlusion, due to suspected cocaine and cannabis abuse, and present our experience of its management.
