Cosmetic Contact Lenses and the Pupillary Light Reflex in Trauma

Anamika Sehgal, Simon Hughes

Abstract

The presence of dilated pupils that have no direct or consensual response to light after traumatic brain injury is an ominous sign, potentially heralding severe intracranial damage. We describe a case in which the presence of tinted contact lenses directly caused misinterpretation of the pupillary light reflex and discuss the clinical importance of this observation.
