Visual recovery in combined central retinal artery and central retinal vein occlusion.

We observed two patients who had combined central retinal artery occlusion and central retinal vein occlusion with severely reduced visual acuity and characteristic retinal changes. Over the course of several months, visual acuity and ophthalmoscopic appearance returned to normal. Both patients had a transient visual loss before their occlusive events and a mild nonconcurrent central retinal vein occlusion in their fellow eye. There was no evidence of inflammatory, vascular, or myeloproliferative disease.
