Post Trauma Vision Syndrome

Post Trauma Vision Syndrome (PTVS) is the most common visual sequel to Mild Traumatic Brain Injury (mTBI) according to the Archives of Physical Medicine and Rehabilitation.

Characteristics of PTVS include spatial disorientation, low blink rate, reduced stereopsis or depth perception, accommodative dysfunction, exotropia or high exophoria, and convergence insufficiency or convergence excess.

The symptoms that correlate with this syndrome include diplopia (double vision), dizziness, headaches with visually demanding tasks, light sensitivity, poor spatial judgment, poor concentration and attention, poor balance and coordination, and reduced visual memory. Along with this cluster of symptoms, reading can be an incredibly daunting task where there is blurred vision, words moving, skipping or repeating of lines of print, omitting small words, and of course difficulty with reading comprehension. It is hypothesized that this neuronal damage has occurred at the midbrain level where there is a disruption in the ability to process central and peripheral visual information simultaneously.
