    Understanding Fundus Autofluorescence: The ABCs of FAF

    AAO 2021
    Comprehensive Ophthalmology, Diagnostic & Imaging , Macular Disease, Retina/Vitreous

    In this video from AAO 2021, presenters review the following:

    • the theoretical basis of retinal autofluorescence, including its biochemical and histological origin
    • the fundus camera, the normal fundus autofluorescence (FAF) image, and future directions in FAF imaging, including the principles of eye tracking, image averaging, and modified cameras (quantified FAF and spectrally resolved FAF)
    • FAF descriptors (iso-FAF, hypo-FAF, and hyper-FAF)
    • the use of FAF and spectral-domain optical coherence tomography (SD-OCT) to systematically evaluate normal aging and major retinal diseases (eg, age-related macular degeneration, hereditary and inflammatory disorders, and nevi/tumor)
