Optical Coherence Tomography Angiography of Retinal Artery Occlusion

The optical coherence tomography angiography (OCTA) microvascular features of branch and central retinal artery occlusion are described and correlated with fluorescein angiographic and clinical findings. There may be differences in the distribution of reduced vascular perfusion/flow between the superficial and deep retinal capillary plexuses in retinal artery occlusive disease. The extent of macular ischemia and the status of flow in the radial peripapillary capillaries can be evaluated with OCTA. Overall, OCTA can be used to monitor changes in vascular flow during the clinical course of retinal artery occlusion.
