OCT Angiography: Imaging of Choroidal and Retinal Tumors

OCTA is a very promising new technology that can be used in the study of posterior segment ocular tumors. When studying melanocytic tumors, the presence of a hyporeflective plexus or hyperreflective ring (in the choriocapillaris layer) surrounding the tumor is associated with a higher risk of malignancy. Larger studies are needed to corroborate these findings. However, we hope that these data can encourage more regular screening for those detected to be at high risk and, hence, reduce the risk of malignancies detected at a late stage.
