The results of the Central Vein Occlusion Study (CVOS) guide the management of macular edema and neovascularization. This study did not show that grid-pattern laser photocoagulation had a significant beneficial effect for the management of decreased visual acuity caused by perfused macular edema in eyes with central retinal vein occlusion (CRVO). Panretinal laser photocoagulation (PRP) was shown to be beneficial for eyes with at least 2 clock hours of iris neovascularization or any angle neovascularization. PRP has not been advocated as prophylaxis for ischemic eyes before the formation of neovascularization. Although treatment of the ocular consequences of CRVO may be guided by the CVOS data, management of the underlying cause of CRVO-the occluded vein itself-was not addressed in the study. Recently, several reports have suggested restoring venous outflow by 1) creating a laser-induced or surgically induced chorioretinal anastomosis, 2) administering recombinant tissue plasminogen activator (rt-PA), 3) cannulating the retinal vein transvitreally, or 4) transecting the posterior scleral ring.

UI	MeSH Term	Description	Entries
D008269	Macular Edema	Fluid accumulation in the outer layer of the MACULA LUTEA that results from intraocular or systemic insults. It may develop in a diffuse pattern where the macula appears thickened or it may acquire the characteristic petaloid appearance referred to as cystoid macular edema. Although macular edema may be associated with various underlying conditions, it is most commonly seen following intraocular surgery, venous occlusive disease, DIABETIC RETINOPATHY, and posterior segment inflammatory disease.

D010959	Tissue Plasminogen Activator	A proteolytic enzyme in the serine protease family found in many tissues which converts PLASMINOGEN to FIBRINOLYSIN. It has fibrin-binding activity and is immunologically different from UROKINASE-TYPE PLASMINOGEN ACTIVATOR. The primary sequence, composed of 527 amino acids, is identical in both the naturally occurring and synthetic proteases.
