Fundus autofluorescence imaging

Fundus autofluorescence (FAF) is a widely utilized method of imaging the retina. It provides a quick and noninvasive method to assess the health of the photoreceptor and retinal pigment epithelium. FAF enables topographic mapping of the metabolic profile of the retina, allowing for disease detection, prognosis, and guidance for the management of a variety of retinal and choroidal diseases. Short-wavelength autofluorescence is the most widely used and studied method of FAF, though advanced techniques such as near-infrared autofluorescence may further expand the clinical utilities of FAF.
