In contrast to that, ischemic CRVO is a seriously blinding disease, and anterior segment neovascularization leading to neovascular glaucoma is its major complication see below. Ophthalmology. 2012 May. 1195:1024-32. Leakage in the macula causes macular enema in which a patient will have blurred vision and loss of portions of the field of vision corresponding to the distribution of the obstructed vein. You should see your eye doctor immediately if you experience symptoms of retinal vascular disease. By contrast, Browning and Antoszyke 20 attempted to produce laser-induced venous anastomosis in 8 eyes with nonischemic CRVO with 20 attempts they had 2 successful anastomoses but not of a therapeutic type, and of those 8 eyes, 3 developed iris neovascularization, retinal neovascularization at the laser site and vitreous haemorrhage, 2 developed traction retinal detachment, and one neovascular glaucoma. There was a significant improvement of visual acuity, spontaneously, in eyes with initial visual acuity of 20/200 or better.
This vein is the one that travels to the blood vessels of the retina. Central retinal vein occlusion; Branch retinal vein occlusion; CRVO; bravo; Vision loss - retinal vein occlusion; Blurry vision - retinal vein occlusion Crouch ER, Crouch ER, Grant BR. When vision loss is severely affected, the damaged membrane may be removed by suture less vitrectomy surgery performed to heal and smooth the macula.
