    Summary

    Electroconvulsive therapy (ECT) can temporarily increase intraocular pressure after convulsions. These elevations in eye pressure are not considered clinically significant or long-lasting.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Anesthesiology

    Background:

    • Electroconvulsive therapy (ECT) is a medical treatment.
    • Understanding the physiological effects of ECT is crucial for patient safety.
    • Intraocular pressure (IOP) changes during medical procedures require monitoring.

    Purpose of the Study:

    • To measure intraocular pressure (IOP) in patients undergoing anesthesia for electroconvulsive therapy (ECT).
    • To assess the impact of post-ECT convulsions on IOP.
    • To determine the duration and significance of IOP elevations following ECT.

    Main Methods:

    • Intraocular pressure (IOP) was measured in 20 patients.
    • Measurements were taken during anesthesia for electroconvulsive therapy (ECT).

  • Control IOP values were established the day before ECT.

    • Main Results:

    • Statistically significant elevations in intraocular pressure (IOP) were observed after ECT-induced convulsions.
    • These IOP elevations remained significant at 5 minutes post-convulsion.
    • The magnitude and duration of IOP increases were not considered clinically concerning.

    Conclusions:

    • Electroconvulsive therapy (ECT) causes transient, non-concerning elevations in intraocular pressure (IOP).
    • Post-ECT convulsions are associated with temporary IOP spikes.
    • Ophthalmological monitoring during ECT may be warranted, but significant risks are unlikely.
