Central Retinal Vein Occlusion with Cilioretinal Arteriolar Insufficiency
This fluorescein angiogram goes with the color fundus photograph labeled with a similar title. This 63 year old man had painless, sudden loss of vision of the left eye. Notice that the branches of the central retinal artery are completely filled with white fluorescein dye, but the cilioretinal artery is not. The part indicated with the white arrows is perfused, but the part indicated with the yellow arrows is not perfused. This underperfusion is a correlate of the ischemic whitening seen in the color fundus photograph.
