There are a variety of reasons to seek care at a Pediatric eye care center, having trouble balancing is a problem that many may not consider to be vision-related but in fact could be addressed through visual therapy. A condition known as Persistent Postural Perceptual Disorder, or 3PD, is a type of dizziness that is not related to vertigo but is caused by a visual stimulus. People with this disorder feel a change in space and motion when they view complex visual stimuli.


3PD is recognized by the American Academy of Optometry and is a disorder that can have drastic negative impacts on one’s life. Seeking treatment at an Austin vision center, therefore, can be a life-changing decision that helps to improve a patient’s day to day life greatly. When the visual system is unable to properly register movement in the environment, visual signals are not properly processed in the brain and can result in dizziness.


Many consider the vestibular system and the workings of the inner ear to be primarily responsible for, and rightfully so. In most people, vision accounts for 25% of balance, but people suffering from 3PD may have a balance system that depends more on balance than others. This could explain why complex visual stimuli affects them so greatly. Another theory as to the roots of 3PD is that there is a type of motion sickness that gets triggered in people who have sensory conflict between their right and left eye. Still another idea is that people with 3PD have difficulty processing the difference between central visual cues and peripheral ones.


By seeking vision care in Austin, people with 3PD can address the underlying causes of their dizziness or balancing problems. Vision therapy uses the concept of habituation to get patients accustomed to more complex visual stimuli. This could begin with simply holding out the thumb against a white background and making small arc rotations. Eventually, a more complex background is used, followed by introducing concentric circles. the goal is to get the patients used to more complex environments, similar to what they might encounter out in the real world.
