Multimodal images of chronic branch retinal vein occlusion.

Two illustrative cases of chronic branch retinal vein occlusion are presented with multimodal imaging, including commercially available optical coherence tomography angiography. In these two patients, retinal ischemia and collateral vessels were well imaged without the need to use traditional fluorescein angiography. Optical coherence tomography angiography provides useful information for the diagnosis and management of patients with branch retinal vein occlusion and other retinal vascular diseases.
