Abstract
Central retinal vein occlusion (CRVO) is a common retinal vascular disorder. In about 20% of the cases of CRVO1, perfusion to the eye is severely reduced, and the eye becomes ischemic and at risk for the development of new blood vessels on the iris. Neovascularization of the iris (NVI) is a serious problem because the new vessels can quickly close off the anterior chamber of the eye, producing the painful and blinding condition of angle closure glaucoma. Treatment to prevent or reverse NVI is aggressive panretinal photocoagulation administered prior to complete angle closure. Identification of CRVO eyes at risk for NVI can be problematic using clinical and angiographic methods2,3.
