Description

Branch retinal vein occlusion (BRVO) is the second most common vascular disorder after diabetic retinopathy. The main complications of BRVO are the presence of macular edema and neovascularization. It is important to differentiate the presence of neovessels from vascular shunts, which can be difficult to differentiate during fundus examination.

Comments

AngioOCT can rule out the presence of neovascularization without the need for fluorescein angiography.

Indication

A 68-year-old hypertensive woman was diagnosed with ORVR with macular edema, treated with intravitreal injections of antiangiogenic agents and sectoral laser panphotocoagulation. During the course of the procedure, vascular changes were observed in the upper temporal arch, suggestive of neovascularization. However, optical coherence tomography angiography (OCT angiography) confirmed that these were vascular shunts.
