Amblyopia/Lazy eye is a serious neurodevelopmental vision problem that causes vision loss in approximately 2-4% of the population or 1 in 30 people. Neuroscience has shown that Amblyopia occurs when there is a unilateral failure in binocular vision, occurring early in life typically infancy or toddlerhood.
When the binocular system is broken at a young age, a neuroadaptation occurs, known as suppression where the signal from one eye is “shut down” by the brain to counteract the confusion created by the broken binocular system. As a result of this unilateral failure of binocular function a cascade of delayed visual function occurs leading to the following:
- Reduced visual acuity (eye sight) in one eye
- Reduced, or no stereo acuity (depth perception)
- Poor saccadic eye movement
- Poor visual processing ability
- Poor eye hand coordination
Only when the complexity of Amblyopia is addressed with a comprehensive developmental vision rehabilitation delivery of care model, will patients have the chance to have successful outcomes in their amblyopia treatment. We must begin to realize that the best care for patients with amblyopia goes beyond patching.
