Automated Assessment of Visual Photosensitivity in Traumatic Brain Injury
Abstract
In this study, we focus on validating a clinical automated instrument, the Ocular Photosensitivity Analyzer (OPA), to quantify an important sequela of Traumatic Brain Injury (TBI), visual photosensitivity (i.e. photophobia). Additionally, we will also assess the effect of various light filtering eyewear with the OPA to investigate whether specific wavelengths of light have significant impact on the management of visual photosensitivity in TBI subjects. Study Questionnaires will be administered in conjunction with OPA testing to better understand the complex interactions between visual photosensitivity and other TBI associated sequela (Dry Eye, Ocular Pain). We will measure VPT in fifty healthy and fifty TBI subjects via the OPA at Visit 1 (baseline) and Visit 2 (1 month)(both with and without light filtering eyewear, in random order) and correlate VPT to the Study Questionnaires. Twenty study participants have been Recruited, Screened, Enrolled, and Completed Visit 1 as well as nine of those study participants have Completed the Phone Interview and Visit 2.
