Research Study on Light Sensitivity after Head Injury
Purpose
Researchers at The Ohio State University College of Optometry are seeking individuals with a recent history of head trauma who are experiencing light sensitivity. The goal of this study is to determine if daily 20 minute fixation training sessions using a colored (red or blue) light target affects symptoms of light sensitivity, or alters other measurements of the eyes and vision including pupil response.
This study will involve attending five 1-2 hour study visits, occurring every 1.5 months for 6 months. Study visits will include answering questions about eye and health history, completing surveys, reading letters on an eye chart, having the pupils measured in response to flashes of light, measuring the side vision, measuring eye alignment and in some cases focusing ability. Outside of the study visits, participants will also complete daily 20 minute fixation training sessions for 6 months using a colored (red or blue) light target, completed at home between study visits.
