Ocular neovascularization is a potential complication. [13]  Anterior segment neovascularization can lead to neovascular glaucoma. Posterior segment neovascularization can lead to vitreous hemorrhage.

Macular edema is another potential complication. [14, 15, 16]  Macular edema is the common cause of decreased vision in CRVO, more so in the nonischemic type. It may resolve with good visual return. The patient may develop permanent degenerative changes with poor visual prognosis and may develop cystoid macular edema leading to lamellar or full-thickness macular hole.

Other potential complications include cellophane maculopathy and macular pucker, as well as optic atrophy.

Reported complications due to treatment with intravitreal injections include endophthalmitis, vitreous hemorrhage, and retinal detachment.
