Retinal Fundus Flavoprotein Fluorescence in Age Related Macular Degeneration

The goal of this clinical trial is to learn if the areas of stressed cells in the retina correlate to areas of disease identified in standard imaging and whether the images are helpful to identify potential areas of concern before symptoms or disease occurs. The main question it aims to answer is: * to evaluate patterns of increased autofluorescence FPF in the setting of geographic atrophy Participants will undergo FPF imaging using the OcuMet Beacon system.

Inclusion Criteria: * 50 years or older and may be either male or female of any race * Established diagnosis of GA due to AMD * GA characteristics: GA area of between 1.25 mm² and 23 mm², with seventy percent of eyes having GA area ranging from 2.5 mm2 to 17.5 mm2. GA may be unifocal or multifocal. GA may be subfoveal or extrafoveal, with twenty-five percent of eyes having subfoveal GA. The presence of concurrent peripapillary atrophy will not exclude subjects from participation * Willing to participate as evidenced by signing the written informed consent Exclusion Criteria: * Unable to tolerate ophthalmic imaging * Presence of neovascular AMD on OCT as confirmed by an ophthalmologist * Presence of significant media opacity preventing adequate retinal imaging * Presence of concurrent retinal disease which may confound assessment
