[Occlusion of a cilioretinal artery associated with occlusion of the central retinal vein].

Cilioretinal artery occlusion (CLRAO) may be occasionally associated with central retinal vein occlusion (CRVO). This combined retinal vascular pathology is described in 5 patients. In this clinical setting the vulnerability of cilioretinal vessels can be explained by the difference in regulatory mechanisms between choroidal and retinal blood flow. The type of CRVO may predict whether the CLRAO is primary or secondary to the CRVO.
