Eligibility Criteria
Inclusion
- Inclusion Criteria
- Participant must understand and sign the protocol's informed consent document (if the participant's vision is impaired to the point where it is not possible to read the informed consent document, the informed consent document will be read in its entirety to the participant).
- Participant must be able to administer the eye drops or have a caretaker administer the eye drops.
- Participant must have geographic atrophy (GA) present in both eyes compatible with age-related macular degeneration (AMD). GA is defined as one or more well-defined, usually more or less 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-ish patch of RPE partial depigmentation may still be classified as early GA. The GA in each eye must be able to be photographed in their entirety and not contiguous with any areas of peripapillary atrophy, which can complicate area measurements.
- Participant must have a steady fixation in the study eye in the foveal or parafoveal area and media clear enough for good quality photographs.
- Female participants of child bearing potential (those who are not post-menopausal or surgically sterile) may participate if they are not lactating and if they agree to adequate birth control methods.
- 5 Exclusion Criteria
- Participant is \> 60 years of age (to minimize fundus changes from causes other than AMD).
- Participant is in another investigational study and actively receiving study therapy.
- Participant is unable to comply with study procedures or follow-up visits.
- Participant has evidence of ocular disease other than AMD in either eye that may confound the outcome of the study (e.g., diabetic retinopathy, uveitis, etc.).
- Participant has a chronic requirement (e.g., ≥ four weeks at a time) for ocular medications for diseases, that in the judgment of the examining physician, are vision threatening or may affect the primary outcome (artificial tears are permitted).
- Participant has evidence of pseudovitelliform macular degeneration that may confound the outcome of the study in either eye.
- Participant with evidence of vitreo-retinal traction maculopathy that may confound the outcome of the study in either eye.
- Participant has a history of laser, photodynamic therapy (PDT), intravitreal injection of any agent (e.g., anti-VEGF, triamcinolone, etc.), or any previous treatment for AMD other than AREDS or equivalent supplement formulation in the study eye.
- Participant has had a vitrectomy, penetrating keratoplasty, trabeculectomy or trabeculoplasty.
- Participant has undergone lens removal in the last three months.
- Participant is on chemotherapy.
- Participant is on ocular or systemic medications known to be toxic to the lens, retina, or optic nerve.
- Participant with a history of malignancy that would compromise the 2-year study survival.
- Participant with a history of ocular Herpes simplex virus.
- Participant with a history of or demonstration of allergy to benzakonium chloride, a preservative agent used in the eye drop.
