Choroidal Neovascular Membranes Diagnosis
To diagnose choroidal neovascular membranes (CNVM), your ophthalmologist will take special photographs of your eye. They take these images using fluorescein angiography (FA) and optical coherence tomography (OCT).
During FA, a fluorescein dye is injected into a vein in your arm. The dye travels throughout the body, including your eyes. FA captures images of your retinal blood vessels as the dye passes through them. The dye highlights abnormal areas, showing your doctor whether you have choroidal neovascular membranes.
OCT scanning creates a cross-section picture of your retina. This image helps your ophthalmologist detect abnormal blood vessels.
