Lipofuscin-associated photo-oxidative stress during fundus autofluorescence imaging
PURPOSE Current standards and guidelines aimed at preventing retinal phototoxicity during intentional exposures do not specifically evaluate the contribution of endogenous photosensitizers. However, certain retinal diseases are characterized by abnormal accumulations of potential photosensitizers such as lipofuscin bisretinoids in the retinal pigment epithelium (RPE). We sought to determine the...
متن کاملFundus Autofluorescence and RPE Lipofuscin in Age-Related Macular Degeneration
Genes that increase susceptibility to age-related macular degeneration (AMD) have been identified; however, since many individuals carrying these risk alleles do not develop disease, other contributors are involved. One additional factor, long implicated in the pathogenesis of AMD, is the lipofuscin of retinal pigment epithelium (RPE). The fluorophores that constitute RPE lipofuscin also serve ...
متن کاملLipofuscin, Lipofuscin-Like Pigments and Autofluorescence
A brief overview is here provided on lipofuscin and lipofuscin-like substances, with particular reference to their biological significance as well as to their cellular origin and pathophysiological role. Special emphasis is also placed on the mutual relationships between lipofuscin and lipofuscin-like lipopigments on one side, and cell autofluorescence on the other.
متن کاملFundus autofluorescence imaging of retinal dystrophies
Fundus autofluorescence (FAF) is a non-invasive imaging technique that enables the visualization of lipofuscin changes in the retinal pigment epithelium. This study aims to illustrate the spectrum of FAF changes in a variety of retinal dystrophies. For this purpose, we examined patients with retinal dystrophies such as Stargardt disease, Best vitelliform macular dystrophy, and retinal dystrophi...
متن کاملFundus autofluorescence imaging: Fundamentals and clinical relevance.
Fundus autofluorescence (FAF), a relatively new imaging modality, focuses on the fluorescent properties of pigments in the retina to generate images that help us view various disease processes from a different perspective. It aids us in the understanding of the pathophysiology of different retinal disorders. Recently, FAF imaging is being used commonly to help us in the diagnosis, prognosis as ...
