Pathophysiology of glaucoma in uveitis

R Ritch

    Transactions of the Ophthalmological Societies of the United Kingdom
    |September 1, 1981
    PubMed
    Summary

    Uveitis can cause secondary glaucoma through various mechanisms, including angle-closure and open-angle glaucoma. Understanding these pathways is key for effective treatment and managing intraocular pressure.

    Area of Science:

    • Ophthalmology
    • Pathophysiology

    Background:

    • Uveitis, inflammation of the eye's middle layer, can lead to secondary glaucoma.
    • Glaucoma associated with uveitis presents complex pathophysiological challenges.

    Purpose of the Study:

    • To elucidate the diverse pathophysiological mechanisms linking uveitis to secondary glaucoma.
    • To highlight the importance of understanding these mechanisms for effective clinical management.

    Main Methods:

    • Review of established pathophysiological pathways for glaucoma secondary to uveitis.
    • Analysis of mechanisms including iris bombé, synechiae formation, and trabecular meshwork compromise.

    Main Results:

    • Secondary glaucoma in uveitis arises from acute angle-closure (iris bombé, posterior synechiae), chronic angle-closure (peripheral anterior synechiae), and open-angle glaucoma (trabecular meshwork obstruction/inflammation).
    • Therapeutic interventions like corticosteroids can paradoxically increase intraocular pressure, complicating management.
    • Secretory hypotony may obscure underlying outflow pathway impairments.

    Conclusions:

    • Successful management of uveitic glaucoma hinges on precise identification of the underlying pathophysiological mechanism.
    • A thorough understanding of these mechanisms is crucial for tailoring treatment strategies and preventing vision loss.
