Visual Impairment and Functional Visual Performance Following Acquired Brain Injury: A Cross-Sectional Study
Objective Visual Impairment and Self-Reported Functional Visual Performance Following Acquired Brain Injury: A Cross-Sectional Observational Study
Source: ClinicalTrials.gov · Last updated 5 Oct 2026
Brief summary (registry, in English)
This cross-sectional observational study aims to characterize acquired visual impairment in adults with acquired brain injury and to examine the relationship between objectively identified visual impairment and self-reported functional visual performance. A total of 108 adults with acquired brain injury, including stroke, traumatic brain injury, and brain tumor, will undergo a standardized visual assessment. Objective visual function will be evaluated across five predefined domains: visual acuity, contrast sensitivity, visual field, oculomotor function, and visual attention/scanning. Self-reported functional visual performance will be assessed using the Revised Self-Report Assessment of Functional Visual Performance (R-SRAFVP). The study will determine the proportion of participants with objectively identified visual impairment and examine the association between the R-SRAFVP score and the number of objectively impaired visual domains. The distribution of impairment across the individual visual domains will also be described.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Other illness
- Pre-existing ocular or visual disorder of sufficient severity to prevent valid assessment of study visual outcomes or to preclude attribution of the identified impairment to acquired brain injury.
- Severe communication impairment preventing reliable completion of the required study assessments.
- Medical, neurological, behavioral, or other condition preventing reliable completion of the required study assessments.
Who the study is looking for
- Adults aged 18-85 years.
- Diagnosis of acquired brain injury, including stroke, traumatic brain injury, or brain tumor.
- Ability to participate in the required study assessment.
- Ability to understand the study procedures and provide informed consent.
