Uveal Tumors: Diagnostic Techniques: Angiography

Fluorescein (FA) and indocyanine green angiography (ICGA) are usually not necessary to diagnose ocular tumors except for retinal tumors, when these ancillary tests assist in establishing the correct diagnosis. Among choroidal tumors, FA and ICGA are particularly useful in establishing the diagnosis of choroidal hemangioma and for revealing choroidal folds. In addition, over the past few decades, these diagnostic procedures have played a pivotal role in expanding our understanding of retinal and choroidal anatomy, pathology, and pathophysiology. These tools are also used to assess disease progression and treatment side effects (radiation retinopathy).
