What is this trial about?

The goal of this clinical trial is to compare measurements of geographic atrophy (GA) area between several types of imaging, in order to assess accuracy. The main question to answer is which imaging device provides measurements that are most similar to the standard of care device. Participants will be patients of a retina doctor at University Station Eye Clinic with geographic atrophy, and can expect to be in the study for 60-75 minutes.

What are the participation requirements?

Yes

Inclusion Criteria

- 50 years or older and may be either male or female and may be 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

No

Exclusion Criteria

- Unable to tolerate opthalmic 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
