Post Trauma Vision Syndrome The visual process is part of a sensorimotor feedback loop, which includes kinesthetic, proprioceptive and vestibular processes. Insults to the cortex produced by an acquired brain injury or stroke cause stress or interference in the central and autonomic nervous systems. As a result, a brain-injured person may experience diplopia, binocular dysfunction, or concentration difficulties. In the past, these symptoms were diagnosed as individual eye problems or muscle imbalances. We now know that these eye problems and other reported difficulties that result from a brain injury often occur because of the interference in the visual process. This, in turn, will cause sensorimotor spatial disorganization. This may also cause an eye to turn out or a strong tendency for both eyes to diverge. The resulting binocular problems are characteristic of Post Trauma Vision Syndrome. Symptoms of Post Trauma Vision Syndrome: - Double vision
- Headaches
- Blurred vision
- Dizziness or nausea
- Light sensitivity
- Attention or concentration difficulties
- Staring behavior (low blink rate)
- Spatial disorientation
- Losing place when reading
- Can’t find beginning of next line when reading
- Comprehension problems when reading
- Visual memory problems
- Pulls away from objects when they are brought close to them
- Exotropia or high exophoria
- Accommodative insufficiency
- Convergence insufficiency
- Poor fixations and pursuits
- Unstable peripheral vision
- Associated neuromotor difficulties with balance, coordination and posture
- Perceived movement of stationary objects
