Fundus autofluorescence and fate of glycoxidized particles injected into subretinal space in rabbit age-related macular degeneration model.

Purpose Abnormal fundus autofluorescence (FAF) is associated with the incidence or progression of dry and wet age-related macular degeneration (AMD). We previously developed a rabbit AMD model with drusen and type-1 choroidal neovascularization (CNV) that mimics the accumulation of lipofuscin using artificial glycoxidized particles. The objective of the current study was to investigate in vitro effects of glycoxidized particles on retinal pigment epithelial (RPE) cells, and the FAF and fate of injected particles in this model.
