Central retinal vein occlusion - Retina Club : Retina Club

Color retinography showing intraretinal hemorrhages scattered in the 4 quadrants, as well as venous tortuosity and engorgement. Choroidal vascular atrophic changes are also seen in the lower periphery.

Enhanced color retinography in the posterior pole where vascular tortuosity, retinal hemorrhages, and perivascular cotton-wool exudates indicating probable ischemia are observed with greater definition.

Fluorescein angiography: During late venous filling, good vascular perfusion is seen throughout the retina. There is no macular edema or significant perimacular vascular permeability. Defects are secondary to scattered hemorrhages.

Angioplex montage: OCT with complete segmentation of the retina, where we observe correct perfusion of the retina.

Description

Central retinal vein occlusion (CRVO) is a blockage in the central vein of the retina, usually due to atherosclerosis, hypertension, or diabetes. On fundusography, hemorrhages in all four quadrants, retinal edema, and venous dilation are seen. Advanced complications include neovascularization and neovascular glaucoma. Treatment may include intravitreal injections of anti-angiogenics, corticosteroids, and laser photocoagulation to manage macular edema and neovascularization.

Comments

The patient was studied at a systemic level to rule out any type of coagulopathy or inflammatory vascular disease, and was subsequently followed up to monitor secondary macular edema. This patient presents a condition compatible with incomplete CRVO, given the absence of macular edema, and the moderate occlusive signs of the condition.

Indication

We present a 69-year-old man referred for scattered retinal hemorrhages, venous tortuosity, and perivascular cotton-wool exudates.
