If your ophthalmologist suspects you may have CNVM, he or she will take special photographs of your eye using fluorescein angiography and optical coherence tomography (OCT).
During fluorescein angiography, a fluorescein dye is injected into a vein in your arm. The dye travels throughout the body, including your eyes. Photographs are taken of your eye as the dye passes through the retinal blood vessels. Abnormal areas will be highlighted by the dye, showing your doctor whether you have choroidal neovascular membranes.
OCT scanning is an imaging technique that creates a cross-section picture of your retina, which helps in detecting abnormal blood vessels.
