Indocyanine green angiography.

A brief survey of the recent ophthalmic literature underscores a resurgence of interest in indocyanine green angiography (ICGA). This imaging method may be particularly useful for the ophthalmologist, as it provides at least a theoretical advantage for improved imaging of the choroidal circulation when compared with fluorescein angiography. New temporal and spatial technological advances (that is, videoangiography and scanning laser ophthalmoscopy, respectively) are primarily responsible for this renewed interest. Thus, ICGA could become instrumental in elucidating the pathogenetic mechanisms of a variety of diseases processes, as well as serving as a diagnostic and therapeutic tool. The flurry of recent publications on ICGA, particularly regarding age-related maculopathy (ARM), suggests a new standard of care for the management of patients with this disorder. However, its usefulness in the diagnosis and management of ARM and other disorders is as yet not entirely clear.
