Vergence dysfunction in mild traumatic brain injury (mTBI): a review

Ophthalmic Physiol Opt. 2011 Sep;31(5):456-68. doi: 10.1111/j.1475-1313.2011.00831.x. Epub 2011 Mar 16.


Vergence eye movements are used to track objects that move in depth in one's binocular visual field to attain and maintain a fused and single percept. The mechanism and control of vergence eye movements involves complex neurological processes that may be compromised in individuals with traumatic brain injury, thus frequently resulting in a wide range of vergence dysfunctions and related near-work symptoms, such as oculomotor-based reading problems. This paper presents a review of the vergence system and its anomalies in mild traumatic brain injury, as well as their diagnostic and therapeutic clinical ramifications. Implications related to brain imaging and human neuroplasticity are also considered.
