![]() This relates to a poor visual understanding of where objects in space are relative to ones self. This can cause many symptoms such as headaches, dizziness, nausea, reduced reading speed/comprehension and more.Ī visual midline shift represents a problem with egocentric localization 2. 2Ĭonvergence Excess means that the eyes cross over each other too much when doing a near task. Common symptoms may include but are not limited to: words running together or blurring while reading, double vision, headaches, falling asleep when reading, reduced reading comprehension. ![]() Convergence Insufficiency will impact ability of all tasks at near 2. This may mean a complete inability to converge, or an inability to sustain convergence through standardized stress tests (base out prism). 2Ĭonvergence Insufficiency means that there is an inability to appropriately use the eyes together at near. Unresolved binocular disturbances will also significantly impede the therapeutic process of both occupational and physical therapists. Binocular dysfunction can cause many negative symptoms such as headaches, dizziness and inability to sustain focus. Some of the affected areas include posture, balance, ability to move through space, reading, driving, playing sports. They can be severely disabling to a person’s ability and performance in many activities of daily living 2. There are varying levels, and many cases will pass ‘routine’ eye testing. Binocular dysfunction refers to an inability to accurately use the two eyes together. Problems with binocular vision are common secondary to ABI 2,9-13. 3,4-8 Unresolved ocular motor disturbance will significantly impeded the therapeutic processes provided by both occupational and physical therapists. ‘Although there may be full ocular movements and no limitations in gaze, there may still be significant impairment to optimal ocular motor function regarding accuracy and speed of eye movements.’ 2 Accurate reaching (eye-hand), navigating through space, and reading require speed and accuracy of eye movements, and will be compromised if ocular motor dysfunction persists. This can happen at a level of being unable to track from finger to finger, or being unable to track accurately through targets on a page. Ocular motor dysfunction (oculomotor dysfunction) refers to inaccurate tracking of the eyes. Ocular motor dysfunction (saccade or pursuit dysfunction) ![]() Many of these symptoms are seen in Post Concussion Syndrome. Inability to tolerate crowded or busy places.Inability to concentrate (reading/computer or even conversation).Visual spatial distortions (visual-vestibular) along with associated neuro-motor (visual-motor output) deficits.Convergence (how the eyes come together),.Problems with the focusing mechanism (accommodation).PTVS is a constellation of signs and symptoms that may include 2: Conditions: Unresolved post trauma vision syndrome will significantly impede the therapeutic processes provided by occupational therapists and physical therapists. Frustratingly, our current limitations in imaging most often mean that nothing is seen on a CT Scan or MRI 2. MTBI includes concussions, minor head trauma, minor head injury, whiplash, and more. While termed mild, the symptoms and impact on life can be anything but. Post Trauma Vision Syndrome (PTVS) is the most common visual sequel of mild Traumatic Brain Injury (mTBI) 1. With over 50 percent of the brain involved in visual function, PTVS is commonly responsible for ongoing symptoms after trauma. The paradigm is now shifting as we understand the importance of the neurological role in eye coordination and information processing, which parallels the changes in vestibular (inner ear) understanding during the last few decades. It has been common to think about “vision” as just seeing clearly and the physiological health of the eye itself, with almost no attention given to how accurately or efficiently the system works. Problems with inaccurate eye tracking may cause you to mix up the information, or feel like you struggle to comprehend it. ![]() If you have PTVS and your eyes do not work together efficiently, you will have a hard time sustaining your attention and may even end up with a headache or migraine. Post Trauma Vision Syndrome refers to deficits in these areas after a concussion, head injury, whiplash, or mild traumatic brain injury (MTBI). As you are reading this text, your brain is controlling how the incoming information is processed, and how your eyes track, coordinate, and focus. ![]()
