Summary

The purpose of the research study is to evaluate how well the Distortion Correction Data Collection (DCDC) App works. The DCDC App is an experimental software application that is being developed at the University of Nebraska Omaha. The DCDC app will map and draw the visual distortions of patients with Age-related Macular degeneration.

Detailed description

This research study is a phase 1 clinical trial to evaluate the efficacy of the Distortion Correction Data Collection (DCDC) App on a computer tablet system. There are two objectives in this study. The primary objective is to evaluate the functionality of the visual distortion app on the tablet computer. Patients will draw their distortions on the tablet screen, and the app will record and correct the distortions.The second objective is to create a distortion data repository (DDR) that contains retinal maps, data pertaining to the anatomical and functional aspects of patients retinas and the distortions. This DDR will be used to correlate retinal health to distortions.The correlation will be key in improving the correction software of the app. Long term, the app will be used to create a diagnostic tool and improve image processing in retinal prosthesis systems. Participating subjects must be at least 55 years of age or older with age-related macular degeneration (AMD). After consent, a chart review will be performed. At the baseline visit, subjects will have an electroretinogram (ERG). At the single study visit, to be scheduled within 2 weeks of the baseline visit, subjects will use the DCDC app on a tablet computer to trace their visual distortions on an Amsler grid. Up to 5 subjects who meet the inclusion/exclusion criteria will be enrolled. The duration of the study is a 2 hour baseline visit and a 1 hour study visit, all within 2 weeks.
