Brain Injury Vision Symptom Survey (BIVSS) Questionnaire.

Purpose: Validation of the Brain Injury Vision Symptom Survey (BIVSS), a self-administered survey for vision symptoms related to traumatic brain injury (TBI).

Methods: A 28-item vision symptom questionnaire was completed by 107 adult subjects (mean age 42.1, 16.

Effects of ocular transverse chromatic aberration on peripheral word identification.

Transverse chromatic aberration (TCA) smears the retinal image of peripheral stimuli. We previously found that TCA significantly reduces the ability to recognize letters presented in the near fovea by degrading image quality and exacerbating crowding effect from adjacent letters. The present study examined whether TCA has a significant effect on near foveal and peripheral word identification, and whether within-word orthographic facilitation interacts with TCA effect to affect word identification.

Effects of ocular transverse chromatic aberration on near foveal letter recognition.

Transverse chromatic aberration (TCA) smears retinal images of peripheral stimuli. In reading, text information is extracted from both foveal and near fovea, where TCA magnitude is relatively small and variable. The present study investigated whether TCA significantly affects near foveal letter identification.

A prospective study of the EYEPORT vision training system.

Background: The purpose of this study was to determine if vision training with the EYEPORT system affects vision and reading performance. (Subsequent to this study, the "E.Y.
