A 6-month study evaluated the safety and efficacy of dexamethasone chinese acupuncture implant 0.35 mg and 0.7 mg compared with a sham procedure in eyes with vision loss due to macular enema associated with bravo and CRVO. 22 In conclusion, the results of the study demonstrated that the dexamethasone implant reduced the risk of further vision loss and increased the chance of improvement in visual acuity in eyes with CRVO. Fekrat et al. 19 reported localized choroid al neovascularization in 21%, mild pre retinal fibrosis in 8%, and pre retinal fibrosis and traction retinal detachment requiring vitrectomy in 4%. Cilioretinal arteries and retinal artery occlusion. This information describes these two different types of vessel occlusion and their affect on vision. The increased level of carbon dioxide might dilate widen the arteries in your retina, increasing blood flow. Sharma S, Grown AC, cress A for the Deco Study Group. Abnormal growth of blood vessels from lack of oxygen to the retina neovascularization can cause additional vision loss and create neovascular glaucoma, with accompanying fluid build-up and high intra ocular pressure that potentially can cause extensive damage to the eye. The possibility of still more long-term complications cannot be ruled out.
