Summary
This review examines how concussion and mild traumatic brain injury impair both accommodation and pupillary responses, causing significant visual symptoms in affected individuals. Findings suggest that vision therapy can meaningfully rehabilitate these deficits, indicating neural plasticity even in chronic cases, which has implications for lighting environments designed to minimize visual discomfort in TBI patients.
Key Findings
- Most accommodative and pupillary response parameters were found to be abnormal following concussion/mild TBI, contributing to visual symptoms.
- Vision therapy produced improvements in accommodative function, demonstrating considerable visual system plasticity even in older adults with chronic brain injury.
- Pupillary dysfunctions identified in this population may indicate disruption to the afferent or efferent pupillary light reflex pathways.
