Abstract
Background: Mild traumatic brain injury (mTBI) is a prevalent neurological condition that results in various physical, emotional, and cognitive impairments. The most common are visual impairments, which affect vision's perceptual, motor, and sensory aspects. Objective: This paper analyzes the pathophysiology of mild traumatic brain injury (mTBI) and its effects on visual and oculomotor functions, focusing on the deficits of the accommodative system and their underlying mechanism. Findings: mTBI frequently causes diffuse axonal injury, resulting in abnormalities of the neurometabolic cascade that impact the brain's visual regions. Accommodative anomalies, including insufficiency, infacility, and spasm, are markedly more common in mTBI patients than in the general population. These deficiencies present as a notable delay in accommodation response, diminished peak velocity, and compromised dynamic responses, possibly due to sensory and motor disturbances. Conclusions: Accommodation disorder is a significant but under-examined component of visual sequelae related to mTBI. Future research should concentrate on the sensory and motor factors contributing to these deficiencies to enhance diagnostic precision and customize rehabilitative strategies.
