Effect of visual training on the vertical vergence amplitude
American Journal of Optometry and Physiological Optics
|October 1, 1985
Summary
Visual training improved vertical vergence amplitudes in patients with vertical heterophoria. Individuals with normal binocular vision did not show similar improvements after training.
Area of Science:
- Ophthalmology
- Neuroscience
- Vision Science
Background:
- Vertical heterophoria can impact visual function.
- Vergence amplitudes are crucial for binocular vision coordination.
- Understanding the effects of visual training is important for therapeutic interventions.
Observation:
- Three mature patients with symptomatic vertical heterophoria underwent visual training.
- The training focused on improving vertical vergence amplitudes.
- Control subjects possessed normal binocularity without vertical heterophoria.
Findings:
- Visual training significantly increased vertical vergence amplitudes in patients with vertical heterophoria.
- The enhanced vergence amplitudes appeared to compensate for the existing heterophoria.
- Subjects without vertical heterophoria did not demonstrate significant changes in vertical vergence amplitudes post-training.
Implications:
- Visual training may be an effective strategy for managing vertical heterophoria.
- Targeted vergence training could restore binocular alignment and visual comfort.
- These findings suggest a potential non-invasive treatment for specific binocular vision disorders.
