Central Retinal Artery Occlusion

Central Retinal Artery Occlusion (CRAO) marks a critical juncture in ophthalmology, characterized by the sudden cessation of blood flow in the central retinal artery, precipitating acute and painless vision loss in one eye. Typically arising from embolic obstruction, often originating from the carotid artery or heart, this condition mandates urgent intervention. While the macular region may display a distinctive cherry-red spot due to maintained choroidal circulation, the loss of vision is profound. Treatment strategies predominantly revolve around dislodging the embolus and reinstating blood flow, albeit with limited options and variable outcomes. Hypertension, diabetes, and cardiovascular disease serve as prominent risk factors, emphasizing the importance of vigilant monitoring and comprehensive management to avert recurrent episodes and mitigate associated complications.
