Photo-induced convulsion after using the translid binocular interactor.

E M Helveston, R Manthey, F D Ellis

    American Journal of Ophthalmology
    |August 1, 1981
    PubMed
    Summary

    A 12-year-old boy developed photo-induced epilepsy from a vision therapy device. This device, intended for eye conditions like exotropia and amblyopia, may pose risks to susceptible individuals.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Medical Devices

    Background:

    • The Translid Binocular Interactor is a device designed for treating ocular motor and sensory abnormalities.
    • It utilizes alternating bright flashes at 10 cycles per second (cps) to stimulate the eyes.

    Observation:

    • A 12-year-old male patient with small-angle secondary exotropia and minimal amblyopia used the Translid Binocular Interactor.
    • The patient subsequently experienced a seizure triggered by light (photo-induced epilepsy).

    Findings:

    • The use of the Translid Binocular Interactor was associated with the onset of photo-induced epilepsy in a pediatric patient.
    • This suggests a potential risk of photic stimulation-induced seizures in individuals with underlying susceptibility.

    Implications:

    • The efficacy of the Translid Binocular Interactor for its intended ophthalmic uses requires further investigation.
    • Clinicians and manufacturers should be aware of the potential risk of inducing seizures in susceptible individuals.
    • Safety protocols and patient screening may be necessary when using devices that employ photic stimulation.
