I would go for duplex of the carotid to figure out the embolic episodes from the carotid artery

Agree D

Cholesterol crystals are observed most frequently. These are called Hollenhorst plaques and are found at the bifurcation of the retinal arterioles.

D.
I think UW had a similar Q, and that was the right answer.
-because the retninal artery is the first (or one of the first) branches of the Internal carotid artery.
