We examined four healthy men who developed cilioretinal artery occlusion associated with central retinal vein occlusion. Unlike previously reported patients with this clinical entity, there appeared to be abnormal central retinal artery inflow, as evidenced by prolonged, irregular filling of the branch retinal arteries with intravenous fluorescein angiography. The patients were treated with systemic corticosteroids. All of the patients had initial improvement in vision. However, three of the four patients had recurrent episodes of visual loss. The final visual acuity was 20/40 or better in three of the four patients.
