Central retinal artery occlusion

Question 1

An 84-year-old man presents with loss of vision in his left eye since the morning. He is otherwise asymptomatic and of note has had no associated eye pain or headaches. His past medical history includes ischaemic heart disease but he is otherwise well. On examination he has no vision in his left eye. The left pupil responds poorly to light but the consensual light reaction is normal. Fundoscopy reveals a red spot over a pale and opaque retina. What is the most likely diagnosis?

Answer 1

Central Retinal Artery Occlusion

Presentation of sudden, painless vision loss in one eye, poor direct pupillary light response, normal consensual light reaction, and fundoscopic findings of a pale and opaque retina with a cherry-red spot are classic features of central retinal artery occlusion (CRAO).
