Central Retinal Artery Occlusion - Fluorescein Angiogram, Example #1

You should look at the Normal Fluorescein Angiogram first for comparison. In this photo, the arteries have not filled with white fluorescein dye even though over one minute has passed from the time the dye was injected into the arm. This extremely delayed filling is a consequence of a blockage of the artery by a piece of atherosclerotic plaque probably originating in the carotid artery of the neck.
