This document discusses fluorescein angiography (FA), including the properties and characteristics of fluorescein, anatomical considerations, the angiographic phases, filters used, interpretation, and reporting of FA. Key points include that fluorescein emits yellow-green light when stimulated by blue light, is mostly bound to proteins but 15% is unbound, the inner blood-retinal barrier is impermeable while the choroid and choriocapillaris are permeable, and there are five angiographic phases - pre-arterial, arterial, arteriovenous, venous, and recirculation.
