Introduction: Accommodative Convergence/Accommodation (AC/A) ratio is constant at one and the same person in the course of life, i.e. the same ratio accommodative convergence monitor any change in accommodation measured in diopters. Such a perfect relationship is possible if there are no refractive anomalies in both eyes and oculomotor imbalance of eye muscles. Material and methods: We are examined 50 patients with close brain injury, and patients which had problems with near vision, accommodation and convergency were reducted, with loss motor fussion, and preserved stereoscopis vision, and showed us, that disturbances are clear motor and folowed with incapable of patient to hold of superposition view to watching object. Results: The difference in average proximity distance vision and reading time with no fatigue after 6 months a statistically significant, the value of t-test, t = 1873 for p
Key words: disorders of AC / A, traumatic brain injury, motor fusion.
