What fundoscopic exam finding is commonly associated with Central Retinal Artery occlusion?

Central Retinal Artery Occlusion (CRAO) is characterized by a specific finding on fundoscopic examination known as a cherry red spot. This phenomenon occurs because the macula, which is the foveal area of the retina and is supplied by the choroidal circulation, remains intact and shows a red spot against the pale, ischemic retina surrounding it. This creates a striking contrast because the area that is affected by the artery occlusion becomes severely ischemic and can appear pale or white.

The presence of the cherry red spot indicates a significant shortage of blood flow to the majority of the retina, while the central macula's preservation highlights this vascular compromise. This is a classic and vital finding in diagnosing CRAO, and understanding it can help healthcare professionals assess and manage patients suspected of having this condition.
