Post Trauma Vision Syndrome: Know the Symptoms
Charles Shidlofsky, OD FCOVD
Depending on what you read, between 50-90% (I believe it is closer to the upper number) of all brain injuries aﬀect the visual system. These #BrainInjuries can stress the nervous system causing interference in the visual process.
Most people look to the point of contact (or the point opposite the contact point) for the aﬀect on the #brain, but frequently the disruption occurs at the mid-brain level. It is in the mid-brain that vision is matched with #proprioceptive, #kinesthetic and #vestibular processes.
Some of the symptoms we hear about are: diﬃculty with #concentration, #DoubleVision, poor eye movement skills, #headaches when reading, visual motion sensitivity, staring behavior and objects appearing to move.. While you can look at these things as separate entities, we now know that there is a common thread when we see these issues. We now utilize the term “Post Trauma Vision Syndrome” as a descriptor for these symptoms.
Common characteristic of Post Trauma Vision Syndrome are:
1) #Exotropia or High Exophoria (an eye turning outward)
2) Diﬃculty with Accommodation (near focus)
3) #Convergence Insuﬃciency- The eyes inability to eﬃciently converge (for example, when reading)
4) Low Blink Rate
7) Unstable #PeripheralVision
These issues are typically caused by a dysfunction of the ambient visual process which creates sensory-motor spatial disorganization. Ultimately, it causes the eye to turn out or a strong tendency for both eyes to diverge.
If you know anyone who has had a #concussion, #stroke or #TraumaticBrainInjury (#TBI) with these symptoms may be helped by seeing a Neuro-Optometrist who can #diagnose and treat #PostTraumaVisionSyndrome (#PTVS).
