Study explores how fundus autofluorescence signals relate to lipofuscin and bisretinoid levels in the retina, suggesting implications for retinal health.
Elevated fundus autofluorescence signals can reflect enhanced lipofuscin in RPE cells, augmented fluorescence due to photooxidation, and/or excess bisretinoid fluorophores in photoreceptor cells due to mishandling of vitamin A aldehyde by dysfunctional cells.
