ISCHEMIC CRVO: There are many serious complications in this type. In addition to the regular complications of vitrectomy, ROM can result in significant haemorrhage and neovascularization at the incision site. It is important to have routine eye exams to detect any developing problems early. Often the laser is also used to stop more damage occurring, so although no sight is restored the likelihood of losing more sight is reduced. A macular pucker, or epiretinal membrane, consists of a slow-growing scar tissue-like membrane that appears on the macula. For retinal detachments, laser surgery is used to fuse the retina to its underlying layer. Clots often travel from other parts of the body.

Medline. One cannot reliably diagnose whether the eye has ischemic or non-ischemic CRVO based purely on ophthalmoscopy see funds photographs in Figure 12. As with veins and arteries in the rest of the body, blockages can occur, causing a disruption to the blood flow and creating serious complications including loss of vision or stroke. Unless normal circulation to the retina can be restored promptly, these cells will die within a few minutes or hours depending on how completely the blood flow is obstructed. If the blockage happens further along in one of the branch arteries then less of your sight will be affected.
