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.
