Light Filtering Lenses and Visual Photosensitivity in Individuals With Traumatic Brain Injury.

ABSTRACT:

Purpose

The purpose of this study was to assess visual photosensitivity using the Ocular Photosensitivity Analyzer (OPA) with and without light filtering lenses in individuals with traumatic brain injury (TBI) and non-TBI controls.

Methods

This cohort study included 46 individuals with TBI (n = 46) and without TBI (n = 46) assessed from May 2021 to August 2023 at a large academic tertiary center. Visual photosensitivity thresholds (VPTs) were measured at two visits (≥1 month apart) under four lens conditions: no lens (NL), plano lenses (PLs), FL-41 lenses (FLs), and gray-filtering lenses (GLs). Lower VPTs indicate greater visual photosensitivity.

Results

Participants with TBI had significantly lower VPTs compared with non-TBI controls across all lens conditions at the
