Nutrition plays an important role in preventing progression of dry age related macular degeneration (AMD), a disease of aging that leads to drusen deposits in the macula causing significant decrease in vision. Drusen contains amyloid protein which is inhibited by curcumin, a natural plant based antioxidant. Oral Longvida curcumin has been shown to accumulate in the retina of human subjects within 10 days of supplementation. This study aims to investigate the duration of oral curcumin supplementation needed to see clinical impact in reducing volume and number of drusen and decreasing choriocapillaris density loss or flow impairment in dry AMD patients. Patients will be given a 12-month course of oral Longvida curcumin and clinical impact will be measured by multimodal retinal imaging (fundus photos, OCT and OCT-A) at day 0, month 3, month 6, and month 12 of supplementation. Previous small studies have shown change in drusen size within 4 6months of curcumin supplementation, given that drusen can naturally fluctuate in size, we want to have a longer study period with a control group to better understand the effects of curcumin on drusen characteristics.

Background: Age-related macular degeneration is a common eye disease in people over 50. The "dry" form of the disease can worsen into geographic atrophy, causing blind spots. Researchers want to learn if replacing older eye cells with younger ones can help treat this disease. Objective: To test the safety of putting cells inside the eye as a possible future treatment for dry age-related macular degeneration. Eligibility: People ages 55 and older who have geographic atrophy with loss of vision. People who have had "wet" macular degeneration in study eye are NOT eligible. Design: Participants will be screened with: * Medical history * Physical exam * Blood and urine tests * Eye exam * Eye photos * Fluorescein angiography. An intravenous (IV) line is placed in an arm vein. A dye is injected. A camera takes pictures of the dye as it flows through the eyes' blood vessels. * Electroretinography. An electrode is taped to participants' forehead. They sit in the dark. After 30 minutes, numbing eye drops and contact lenses are placed in their eyes. They watch flashing lights. * Tuberculosis test * Chest X-ray * Electrocardiography. Sticky pads are placed on participants' chest to record the heart's electrical activity. Participants will have at least 14 study visits over 5 and a half years. They will repeat screening tests. Participants will have retinal pigment epithelium (RPE) transplantation surgery in one eye. For this, cells from participants' blood are turned into RPE cells. These cells are placed in their eye through a cut in their retina. They will get dilating eye drops, an IV line, and anesthesia that may make them sleep. A gas bubble will be put in their eye to help it heal. Participants will receive immunosuppressive medications to avoid transplant rejection. Participants will be contacted yearly for up to 15 years.
The study is designed to identify the maximum tolerated dose (MTD) for intravitreal (IVT) administration of GEM103 in subjects with geographic atrophy (GA) secondary to dry AMD. Safety and tolerability of a single dose of GEM103 will be assessed based on the occurrence of dose-limiting toxicities (DLTs). Each subject will be followed for safety, pharmacokinetic (PK), clinical, and biomarker evaluations. Three escalating dose cohorts are planned.
This LIGHTSITE III study is a double-masked, sham-controlled, parallel design, prospective multi-site study for the use of PBM as a treatment for visual impairment in subjects with dry AMD.
From 3 large patient databases, patients diagnosed with AMD who have never taken levodopa(L-DOPA) containing medications have a mean age of diagnosis at 71 years. Patients who have been treated with L-DOPA containing medications have a mean age of diagnosis of AMD at 79 years. L-DOPA binds to GPR143 in the retinal pigment epithelium, and releases PEDF, which protects the retina and downregulates VEGF, which is the cause of neovascularization. The Investigators will evaluate the safety and tolerability of carbidopa-levodopa in patients with Neovascular AMD, and measure the effects on visual acuity and retinal abnormalities due to "wet" (neovascular) AMD. The Investigators will evaluate the safety and tolerability of carbidopa-levodopa in patients with Dry AMD and Geographic Atrophy, and measure the effects on visual acuity, area of geographic atrophy and other retinal abnormalities due to "dry" AMD.
Age-related macular degeneration (AMD) is an eye disease which causes people to lose their sharp central vision over time. Aging damages the macula, which is in the middle of the retina - the light-sensitive part at the back of the eye. There are 2 types of AMD - wet AMD and dry AMD. The advanced stage of dry AMD causes vision loss. This is known as geographic atrophy. AMD makes everyday tasks like reading or driving difficult. ASP7317 is a potential new treatment for people with AMD. ASP7317 are human stem cells which have changed into cells found in the retina. ASP7317 is injected under the macula. It is hoped that ASP7317 will replace some of the damaged cells in the macula and improve vision for people with dry AMD. Before ASP7317 is available as a treatment, the researchers need to check its safety and how well it is tolerated. They will also check for signs of improved vision. People taking part in this study will be older people who have geographic atrophy caused by dry AMD. This is an open-label study. This means that people in this study and clinic staff will know that people will receive ASP7317. There will be 3 doses of ASP7317. These are low, medium and high numbers of cells. ASP7317 will be injected under the macula after the person is given either a local or a general anesthetic. To prevent the body from rejecting the cells, people will take tablets of tacrolimus a few days before receiving ASP7317 for up to a few weeks afterwards. Other medicines will be taken during this time to stop infections. There will be 2 groups in the study. Group 1 will be people with severe vision loss and Group 2 will be people with moderate vision loss. There will be different small groups of people within Group 1 and Group 2, with each small group receiving 1 of the 3 doses of ASP7317. Different small groups of people within Group 1 and Group 2 will receive lower to higher doses of ASP7317. Each small group will only receive 1 dose. Group 1 will start treatment first. At each dose, a medical expert panel will check the results of the first person in the group to decide if the rest of the group will receive the same dose. Then, the panel will decide if more people may receive the same dose or if the next group may receive the next highest dose. The panel will use the results from the lower dose of Group 1 to decide when Group 2 starts treatment (also at the lower dose). The panel will also use the results of the middle and higher doses in Group 1 to decide when and how many people in Group 2 can receive these doses. During the study, people will visit the clinic several times for up to 12 months (1 year). During all visits, the study doctors will check for any medical problems after receiving ASP7317. Vital signs will be checked a few days before treatment with ASP7317 and up to about a month afterwards. Vital signs include blood pressure, pulse, and temperature. At some visits, the study doctors will also take blood samples for blood tests. At most visits, people will have eye tests and have different images, scans, and measurements taken. This could be for the affected eye or both eyes, depending on the test. People can visit the clinic extra times, if needed.

The cells will be delivered via needle injection into the eye.
Study to evaluate the safety and tolerability of MC-1101, a potential topical treatment for non-edxudative age Related Macular Degeneration (AMD) in medically stable individuals.
The study hypothesis is that patients with dry age-related macular degeneration experience visual function impairments such as defects in dark adaptation, glare intolerance, poor light transition and reading in low lighting conditions. Studies have shown that patients in the early phases of AMD with normal visual acuity commonly reported difficulty with these visual functions but there have been no systematic studies evaluating these deficits in this population. This prospective, exploratory study will include up to 130 patients with dry AMD and 60 controls. These patients will undergo the following non-invasive visual function testing: * microperimetry with eye tracking * low luminance visual acuity * specialized color vision (cone-specific) * contrast testing and night vision testing. High-resolution spectral domain optical coherence tomography (SDOCT) images will be taken of the central retina using the Spectralis OCT unit. The values of visual function tested will be correlated with the findings on SDOCT (volume/amount of drusen present in early AMD). There are no known risks to the subjects beyond what is normal for standard examinations of the eye, visual function testing and standard ocular photographic procedures.
