The Head Injury-associated Photosensitivity and Pupillary Function (HIPP) Study

NCT01942564 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 40

Last updated 2017-09-25

No results posted yet for this study

Summary

After a head injury, many people find that exposure to light causes them increased discomfort. By measuring how the pupil in the eye constricts to flashes of red and blue light, this study will investigate whether this phenomenon is due to a change in the eye's sensitivity to light.
