Characteristics of normal human retinal pigment epithelium cells with extremes of autofluorescence or intracellular granule count.

Ann Eye Sci 2021 Mar 15;6. Epub 2021 Mar 15.

Department of Ophthalmology, University Hospital Bonn, Bonn, Germany.

Background: Cells of the retinal pigment epithelium (RPE) accumulate different kinds of granules (lipofuscin, melanolipofuscin, melanosomes) within their cell bodies, with lipofuscin and melanolipofuscin being autofluorescent after blue light excitation. High amounts of lipofuscin granules within the RPE have been associated with the development of RPE cell death and age-related macular degeneration (AMD); however, this has not been confirmed in histology so far. Here, based on our previous dataset of RPE granule characteristics, we report the characteristics of RPE cells from human donor eyes that show either high or low numbers of intracellular granules or high or low autofluorescence (AF) intensities.
