* INCLUSION CRITERIA: To be eligible, the following inclusion criteria must be met, where applicable. 1. Participant must be 55 years of age or older. 2. Participant must understand and sign the protocol s informed consent document. 3. Participant must have evidence of early or intermediate AMD as defined by characteristic presence of drusen and/or pigmentary changes. 4. Participant is enrolled in one of the following screening protocols: 08-EI-0102, 08-EI-0169 (closed), 08-EI-0043, 12-EI-0042, 11-EI-0147, or 16-EI-0134. EXCLUSION CRITERIA: A participant is not eligible if any of the following exclusion criteria are present. 1. Participant is actively receiving study therapy in another investigational study. 2. Participant is unable to comply with study procedures or follow-up visits. 3. Participant is on ocular or systemic medications known to be toxic to the lens, retina or optic nerve (e.g., ethambutol, chloroquine, or hydroxychloroquine). STUDY EYE ELIGIBILITY CRITERIA: The participant must have at least one eye meeting all inclusion criteria and none of the exclusion criteria listed below. STUDY EYE INCLUSION CRITERIA: 1. The study eye(s) must have GA compatible with dry AMD. GA is defined as one or more well-defined and often circular patches of partial or complete depigmentation of the RPE, typically with exposure of underlying choroidal blood vessels. Even if much of the RPE appears to be preserved and large choroidal vessels are not visible, a round patch of RPE partial depigmentation may be classified as early GA. The GA in the study eye must be able to be photographed in their entirety and it must not be contiguous with any areas of peripapillary atrophy, which can complicate area measurements. 2. The study eye(s) must have clarity of ocular media and degree of pupil dilation sufficient to permit adequate fundus photographs. STUDY EYE EXCLUSION CRITERIA: 1. Current evidence of neovascularization as determined by the treating physician or a history of treatments for neovascularization. 2. Evidence of retinal atrophy due to causes other than atrophic AMD. 3. Current evidence or history of ocular disorders in the study eye that might confound study outcome measures, including (but not limited to): 1. non-proliferative diabetic retinopathy involving 10 or more hemorrhages or microaneurysms, or active proliferative diabetic retinopathy 2. Branch or central retinal vein or artery occlusion 3. Macular hole 4. Pathologic myopia 5. Uveitis 6. Pseudovitelliform maculopathy 4. History of vitreoretinal surgery. 5. Need for ocular surgery during the course of the study. 6. Recent history of lens removal (\< 3 months prior to enrollment) or Yttrium Aluminum Garnet (YAG) laser capsulotomy (\< 1 month prior to enrollment).
