Fluorescein angiography. Part 1: Technique and normal study.
1. Fluorescein angiography is a relatively noninvasive diagnostic test which provides the ophthalmic practitioner with anatomic and physiologic information about the ocular structures. 2. Once the dye solution is injected, the photographer observes the fundus through the camera until it appears in the retinal vessels. Photographs are then taken in a rapid sequence. 3. The retinal arteries fill rapidly and evenly within two seconds following the initial choroidal flush. The dye circulates through the whole arterial tree in the body, and in the late stage angiogram recirculation can be seen in the retinal blood vessels.
