Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

With the aging of the population, the prevalence of age-related macular degeneration (AMD) eye disease has resulted in a large number of people suffering from central vision loss. In fact, the most prevalent cause of blindness among veterans is AMD. Since the number of elderly veterans is expected to double in the next 10 years, loss of vision due to AMD is also expected to proportionally and considerably escalate. People with impaired vision have difficulty with daily activities, such as, reading, driving, and recognizing faces. The goal of the research project is to provide information on factors that contribute to visual impairment. This knowledge is necessary for the development of innovative approaches that will optimize the benefit of vision rehabilitation techniques, aimed at improving vision, thus allowing our veterans to maintain function and productivity. The findings from the proposed research will benefit our veterans and all aging people.
