Retinal Vascular Complications in Cocaine Abuse: A Case Report and a Literature Review.

This comprehensive review examines the ocular vascular complications of cocaine use, focusing on its effects on retinal vasculature and inflammation. A rare case of bilateral frosted branch angiitis (FBA) in a 48-year-old man with a history of intranasal cocaine abuse is presented as an illustrative example to stimulate discussion. The case highlights severe retinal ischemia and vascular sheathing, with no identifiable infectious or autoimmune cause, ultimately complicated by systemic vascular events.
