What is a Retinal Artery Occlusion?
The retina has two blood supplies. The first is under the retina called the choroid. The second, is a large artery (central retinal artery) and a large vein (central retinal vein) in the center of the optic nerve. Sometimes clots can form in the artery that block blood flow to the retina. This is similar to a stroke, and will result in an area of the retina that is blind.

However, it is very important to be evaluated for sources of emboli (carotid ultrasound and 2-D echo of heart) or inflammatory conditions such as giant cell arteritis, to prevent future strokes.
