Biofeedback training of visual acuity and myopia: a pilot study.
American Journal of Optometry and Physiological Optics
|January 1, 1987
Summary
Biofeedback training using the Accommotrac Vision Trainer showed some visual acuity improvements in subjects, but did not alter refractive error. Further research is needed to confirm if biofeedback training alone caused these visual acuity gains.
Area of Science:
- Ophthalmology
- Vision Science
- Neuroscience
Background:
- Myopia and reduced visual acuity are significant vision concerns.
- Biofeedback training offers a potential non-invasive approach to vision improvement.
- Understanding the efficacy of specific biofeedback devices is crucial for clinical application.
Purpose of the Study:
- To investigate the effectiveness of biofeedback training for accommodation.
- To determine if the Accommotrac Vision Trainer can improve visual acuity (VA).
- To assess the potential of this training to reduce myopia.
Main Methods:
- Employed a single-subject research design with nine participants.
- Utilized the Accommotrac Vision Trainer for biofeedback training of accommodation.
- Measured visual acuity (VA) and refractive error before and after the intervention.
Main Results:
- Some participants demonstrated improvements in visual acuity (VA).
- No significant changes in refractive error were observed across subjects.
- The study could not definitively attribute VA improvements solely to biofeedback due to potential learning effects.
Conclusions:
- Biofeedback training of accommodation may offer some benefits for visual acuity.
- The Accommotrac Vision Trainer's specific impact on myopia requires further investigation.
- Future studies should incorporate control groups to isolate the effects of biofeedback training.
