M CRAO

TAKE-HOME MESSAGE

• This article presents an excellent overview of appropriate management of central retinal artery occlusion (CRAO), branch retinal artery occlusion (BRAO), and amaurosis fugax based on the review of literature as well as author’s own research. The author suggests that urgent evaluations of carotid artery, heart, fasting lipid levels, and complete blood count constitute the most important investigations, rather than neurological evaluations—unless, there are neurological symptoms.
• The author also mentions that there is a misconception that the absence of any abnormality on carotid artery evaluation or echocardiography of the heart always rules out those sites as the source of embolism.
