Biofeedback enhanced strabismus therapy

M D van Brocklin, T R Vasché, R R Hirons

    Journal of the American Optometric Association
    |September 1, 1981

    Summary

    Biofeedback therapy using infrared eye tracking shows promise for treating strabismus. Integrating this approach before traditional vision therapy may offer optimal results for strabismic patients.

    Area of Science:

    • Ophthalmology
    • Vision Science
    • Biomedical Engineering

    Background:

    • Strabismus, or eye misalignment, is a common condition affecting visual development.
    • Previous laboratory studies demonstrated biofeedback's efficacy in strabismus treatment.
    • Infrared eye position monitoring offers a precise method for tracking eye movements.

    Purpose of the Study:

    • To evaluate the effectiveness of biofeedback-enhanced vision therapy compared to traditional therapy for strabismus.
    • To determine if biofeedback offers an advantage when integrated with or preceding traditional vision therapy.

    Main Methods:

    • Seven matched pairs of strabismic patients were recruited.
    • One patient from each pair received biofeedback-enhanced vision therapy.
    • The other patient received traditional vision therapy.
    • Cover test data were collected during training sessions to assess eye alignment.

    Main Results:

    • Biofeedback-enhanced training demonstrated an advantage in treating strabismus in some, but not all, patients.
    • The study observed variability in treatment outcomes.
    • Cover test data indicated specific scenarios where biofeedback was more beneficial.

    Conclusions:

    • Biofeedback therapy, particularly with infrared eye monitoring, shows potential for strabismus treatment.
    • The optimal application of biofeedback may be as a preparatory intervention before traditional vision therapy.
    • Further research is warranted to refine biofeedback integration strategies for diverse strabismus cases.
