Study Summary

Previous work collectively suggests that rod-mediated dark adaptation (RMDA) is a promising candidate as a functional endpoint measure for evaluating interventions to slow early progression of age-related macular degeneration (AMD). However, there is no agreement among the clinical, research and regulatory communities as to what constitutes a clinically (practically) significant slowing in RMDA. Treatments for AMD are often not considered efficacious if they do not result in a criterion level of improvement in vision. But how much change in the rate of dark adaptation constitutes a clinically significant change? Until this issue is resolved, progress in developing clinical trials on early AMD are at a standstill since there is no functional endpoint to be used in the trial. One approach to establishing clinical significance is to examine how RMDA relates to the performance of an everyday visual task under low luminance conditions, such as night driving or reading. However, such data are not yet available. The purpose of this project is to examine the relationship between RMDA and night-time driving and reading under poor illumination. This information will guide the development of a definition of a clinically significant difference in RMDA that can be used in designing clinical trials on early AMD.
