Development and Evaluation of Functional Visual Field and Navigation Endpoints in Moderate to Profound Inherited Retinal Disease (DEFINE-IRD)
Ray Therapeutics, Inc.
Summary
The Vision Research and Assessment Institute (VRAI) was established with the purpose of serving as a testing facility for efficacy endpoints for patients with Low Vision. The mission of the VRAI is to enable the highest quality, standardized efficacy testing of patients with visual impairment. The VRAI facilitates the development and refinement of existing endpoints specifically for testing patients with Low Vision.
Description
This observational, non-interventional study is designed to assess both the operational feasibility and the measurement properties of selected visual function assessments in this population. The study will emphasize outcome measures that are sensitive to peripheral visual function and that reflect real-world functional abilities, including spatial orientation, mobility, and wayfinding.
