Brief Summary
The objective of this study is to compare Cirrus HD-OCT automated measurements of the illumination area under the retinal pigment epithelium (RPE) to expert manual measurements of areas of hypofluorescence typical of geographic atrophy in fundus autofluorescence (FAF) images.

Outcome Measures
Primary Outcomes (1)
Difference in mm Squared of Cirrus HD-OCT Automated Measurements of the Illumination Areaa Under the RPE to Expert Manual Measurement of Areas of Hypofluorescence Typical of Geographic Atrophy (GA).
In retinal areas with atrophy, light emitted from the Cirrus penetrates the sclera and choroid which are more reflecting compared with the Retinal Pigment Epithelium (RPE). The areas with higher illumination are associated with areas of Geographic Atrophy (GA), and allow to quantify how big is the area of atrophy. The study will assess the difference between Cirrus HD-OCT measurements of areas of increased illumination under the RPE to hypofluorescence areas on fundus photos as assessed manually by retina specialists.

Eligibility Criteria
Primary Care Clinic
You may qualify if:
- Males or females 50 years of age and older diagnosed to have advanced dry AMD with geographic atrophy.
- Geographic atrophy lesions should:
- Not be greater than 5 mm at the widest diameter. The entire lesion(s) should fit into the 6x6 mm scan area of the Cirrus HD-OCT.
- Not be smaller than 1.25 mm2.
- Not be confluent with peri-papillary atrophy.
- Not be combined with other lesions such as CNVs.
- Able and willing to make the required study visit.
- Able and willing to give consent and follow study instructions.
You may not qualify if:
- History of retinal surgery, laser photocoagulation, and/or radiation therapy to the eye.
- Evidence of other retinal diseases of the eye, including wet AMD, diabetic retinopathy, diabetic macular edema, or significant vitreomacular traction upon dilated examination, or upon evaluation of retinal photos.
- Thick media opacity or inability to fixate that precludes obtaining acceptable scans.
- Concomitant use of hydrochloroquine and chloroquine.
- Unable to make the required study visit.
- Unable to give consent or follow study instructions.
