A case of a cilioretinal artery supplying the entire retina.

The cilioretinal artery commonly supplies a small area of the retina, usually the macula. It can serve a valuable purpose in preserving the central vision in central retinal artery occlusion. We describe a case, where the total retinal circulation is from the cilioretinal artery in one eye and an abnormal central retinal artery branching in the other eye. The clinical relevance of cilioretinal artery in the eye is discussed.
