Official Title

Prospective Natural History Study of Fundus Autofluorescence Imaging in Age-related Macular Degeneration (FAM-Study) Using Confocal Scanning Laser Ophthalmoscopy


Age-related macular degeneration (AMD) is the leading cause of legal blindness in the
industrialized world beyond 50 years of age. Ageing changes of the retinal pigment
epithelium (RPE) play a key role in the pathogenesis of the disease. In postmitotic RPE
cells autofluorescent lipofuscin granules accumulate with age in the lysosomal compartment
mainly as a byproduct of constant phagocytosis of membranous disks shed from photoreceptor
outer segments. With the advent of confocal scanning laser ophthalmoscopy fundus
autofluorescence mediated by RPE-lipofuscin accumulation can be visualized in vivo: We plan
to identify fundus autofluorescence changes as predictive factors for the development of
late stage manifestations and their variation over time. Furthermore, we plan to determine
the effect of increased focal accumulations of autofluorescent material on retinal
sensitivity using fundus perimetry. Examination of human donor eyes with AMD will allow for
correlation of fundus autofluorescence alterations in vivo and in vitro. These
investigations will be performed not only to better understand the role of lipofuscin
accumulation in AMD but also to manipulate these mechanisms for both experimental and
therapeutic ends.
