Choroidal Rupture - Fluorescein Angiogram
You should look at the Normal Fluorescein Angiogram first to provide a basis for comparison. The fluorescein dye appears white in this photo and highlights the vertical scar which has broken the darker tissue under the retina in the central macula. In the center of this scar, a broader, white area is the subretinal membrane of abnormal blood vessels which are somewhat leaky. This membrane, or net, can be treated with photodynamic therapy, a type of cold laser applied after infusion of the drug verteporfin, which binds to the membrane and elicits clot formation under the influence of the laser.
