Glaucoma in Sturge-Weber syndrome.

G W Cibis, R C Tripathi, B J Tripathi

    Ophthalmology
    |September 1, 1984

    Summary

    Glaucoma in Sturge-Weber syndrome may stem from premature aging of the eye's drainage system or congenital anomalies. Abnormal blood vessel development likely contributes to these glaucoma mechanisms.

    Area of Science:

    • Ophthalmology
    • Pathology
    • Genetics

    Background:

    • Sturge-Weber syndrome is a rare congenital disorder characterized by a distinctive facial birthmark and abnormalities of the brain and eyes.
    • Glaucoma is a common and serious complication of Sturge-Weber syndrome, potentially leading to vision loss.

    Observation:

    • Histopathological examination of trabeculectomy specimens from three patients with Sturge-Weber syndrome revealed changes in the trabecular meshwork-Schlemm's canal system.
    • These observed changes were comparable to those seen in age-related glaucoma and primary open-angle glaucoma.

    Findings:

    • Two primary mechanisms for glaucoma development in Sturge-Weber syndrome were identified: anomalous chamber angles in congenital cases and premature aging of the trabecular meshwork-Schlemm's canal complex in juvenile-onset glaucoma.
    • Histopathological evidence supports premature aging as a key factor in juvenile glaucoma associated with this syndrome.

    Implications:

    • The findings suggest that abnormal hemodynamics, resulting from the persistence of Streeter's primordial vascular plexus, underlie both congenital and juvenile glaucoma in Sturge-Weber syndrome.
    • Understanding these mechanisms can inform targeted therapeutic strategies for managing glaucoma in affected individuals.
