Midbrain corectopia

J B Selhorst, W F Hoyt, M Feinsod

    Archives of Neurology
    |March 1, 1976
    PubMed
    Summary
    This summary is machine-generated.

    Intermittent corectopia, a pupil shape change, was seen in a patient with midbrain infarction. This finding relates to how the Edinger-Westphal nucleus controls pupil muscles.

    Area of Science:

    • Neuroscience
    • Ophthalmology
    • Neuropathology

    Background:

    • Corectopia, or pupil displacement, is typically associated with structural abnormalities or trauma.
    • Understanding the neural control of pupillary miosis and mydriasis is crucial for diagnosing neurological disorders.

    Observation:

    • A patient with bilateral, rostral midbrain infarction presented with intermittent corectopia.
    • Neuropathologic examination revealed intact Edinger-Westphal nuclei despite the infarction.

    Findings:

    • The observed intermittent corectopia was explained by segmental innervation of the pupil by the Edinger-Westphal nucleus.
    • In cases of a paralyzed pupillary dilator muscle, selective central inhibition of sphincter tone can lead to an eccentric and oval pupil.

    Implications:

    • This case provides insight into the segmental control of pupillary function by the Edinger-Westphal nucleus.
    • The findings may help in understanding and diagnosing specific types of pupillary abnormalities linked to midbrain lesions.
