A patient with central retinal vein occlusion (CRVO) may present with a number clinical signs and symptoms. Ischemic central RVO tends to be more severe. The central retinal vein may be affected as it exits the eye or proximal to the lamina cribosa of the optic nerve.
A patient with central RVO may present with poor visual acuity. This may develop suddenly. Some patients may be asymptomatic.

(1) multiple intraretinal hemorrhages, seen in all quadrants
(2) multiple cotton wool spots
(3) tortuous and dilated retinal veins
(4) edema and/or hyperemia of the optic disc
