Purpose:
This article illustrates the ability of optical coherence tomography angiography (OCTA) to aid in the diagnostic workup and management of occlusive retinal vasculitis over time.
Methods:
A case presentation is discussed.
Results:
In this case, OCTA helped define the extent and evolution of superficial and deep retinal capillary plexus occlusion and reperfusion over the treatment course.
Conclusions:
OCTA detects blood flow and maps retinal vasculature at the capillary level without the use of intravenous dye. Serial image acquisition can reveal patterns of ischemia and reperfusion in retinal vascular conditions as they evolve and respond to therapy, providing more granular information regarding the status of the retinal microvasculature that may guide treatment.
