A Rapid, Portable Test to Monitor Gradual Vision Loss in Dry Age-Related Macular

DESCRIPTION (provided by applicant): The worldwide demographic trends of aging and obesity will increase the global incidence of blinding eye diseases, which impose significant psychosocial and economic burdens. The leading cause of blindness in the developed world is Age-related Macular Degeneration (AMD), which causes the progressive loss of central vision. Because dry AMD, which exhibits gradual vision loss and constitutes most AMD cases, is currently untreatable, successful clinical management of AMD critically depends on monitoring these cases for the potential conversion to wet AMD. Timely detection of the rapid vision loss that marks the onset of wet AMD enables the early clinical intervention, via intra-vitreal injections, which is related with successful outcomes. To improve on current clinical standards for home-based visual monitoring (Amsler charts), we have developed a research prototype of a mobile Health (mHealth) application that enables rapid, reliable, and portable contrast sensitivity
