Superior oblique myokymia.

M L Rosenberg, J S Glaser

    Annals of Neurology
    |June 1, 1983
    PubMed
    Summary

    Superior oblique myokymia, an unusual rotary eye tremor, presents with varied symptoms. While carbamazepine offers temporary relief, it does not alter the disease's long-term, benign course affecting only the superior oblique muscle.

    Area of Science:

    • Ophthalmology
    • Neuro-ophthalmology

    Background:

    • Superior oblique myokymia is typically viewed as a benign, uniocular rotary microtremor.
    • It is often considered easily manageable with carbamazepine treatment.

    Observation:

    • Eleven new cases of superior oblique myokymia were analyzed.
    • One case exhibited a unique combination of motility issues, highlighting clinical variability.
    • Long-term patient follow-up revealed a pattern of spontaneous remissions and relapses.

    Findings:

    • Carbamazepine provided short-term symptomatic benefit for most patients.
    • The medication did not influence the long-term progression or natural history of the condition.
    • No patients showed signs of other neurological disorders during the study period.

    Implications:

    • Superior oblique myokymia demonstrates variable clinical presentations beyond typical rotary microtremors.
    • The condition appears to be a benign, permanent disorder exclusively affecting the superior oblique muscle.
    • Current pharmacological treatments like carbamazepine offer limited long-term efficacy for managing this eye movement disorder.
