Vision Therapy Flashcards
Vision therapy
Use of therapeutic procedures and treatment for patients with visual disorders like strabismus, amblyopia, accommodative dysfunction, diplopia, and eye fatigue.
Vision rehabilitation
Treatment for patients with TBI (traumatic brain injury)
Referes to the brain’s ability to change and adapt in response to new experiences
Neuroplasticity
Defined as binocular or monocular decrease in BCVA due to pattern visual deprivation and/or abnormal binocular interaction during visual immaturity
Amblyopia
Best compensated VA is 20/40 or worse in either or both eyes
Amblyopia
4 types of amblyopia
Strabismic amblyopia
Form deprivation amblyopia
Anisometropia
Isoametropia
When both eyes are open and uncovered one eye is pointed at the target and the other eye is pointed somewhere else
Strabismus
3 broad factors in etiology of strab:
Anatomical
Optical
Innervational
Anatomical
abnormalities of EOM, ligaments, tendons, orbital contents
Optical
refractive anisometropia, high RE, media opacities
Innervational
due to impairment of cranial nerves III, IV, VI, which represent the majority of cases.
When both the fovea have a common visual direction and the retinal elements nasal to the fovea in one eye corresponds to the retina elements temporal to the fovea in the other eye.
Normal Retinal Correspondence
Occurs when the images of the two different objects compete to be represented on the internal rep of reality
Confusion
Best compensated VA is. 20/40 or worse in either or both eyes
Amblyopia
It refers to a condition where the refractive error in one eye is much worse than the refractive error in the other eye.
Anisometropia
