Official title
The Natural History of Geographic Atrophy Associated With Age-Related Macular Degeneration
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: Age-related macular degeneration (AMD) affects the macula in the eye. This is the central part of the retina. It is needed for sharp, clear vision and activities like reading and driving. AMD is the leading cause of vision loss in Americans 60 years of age and older. An advanced form of AMD is called geographic atrophy or GA. It happens when light-sensitive cells in the macula die so much that central vision decreases. Objective: To learn more about geographic atrophy associated with age-related macular degeneration. Eligibility: Adults at least 55 years old with a certain kind of GA. They must be enrolled in study 08-EI-0102, 08-EI-0169, 08-EI-0043, 12-EI-0042, or 11-EI-0147 but no other studies. Design: Participants will be screened with medical history, physical exam, and an eye exam. Participants will have study visits every 3 months for 15 months, then every 6 months. They will be in the study almost 4 years. Visits will last about 8 hours. At each visit, participants may have: * Medical and eye history. Participants will answer questions about their general health and eye health. They may answer written questions about how their eye problems affect their life. * Eye exam and photographs. Eye pressure will be measured and eye movements will be checked. Pupils will be dilated with drops. The thickness of the retina will be measured and photos of the eye may be taken.
