Immunofluorescent studies on the trabecular meshwork in open-angle glaucoma

M B Shields, R C McCoy, J D Shelburne

    Investigative Ophthalmology
    |December 1, 1976
    PubMed
    Summary

    This study investigated an immunogenic mechanism in open-angle glaucoma. Immunofluorescence assays found no evidence of specific immunoglobulins or complement components, suggesting immunity is not involved.

    Area of Science:

    • Ophthalmology
    • Immunology

    Background:

    • Open-angle glaucoma is characterized by increased gamma globulin and plasma cells in the trabecular meshwork.
    • This observation raises the possibility of an immunogenic mechanism contributing to the disease.

    Purpose of the Study:

    • To investigate the potential immunogenic mechanism in open-angle glaucoma.
    • To determine if specific immunoglobulins or complement components are present in the trabecular meshwork.

    Main Methods:

    • Immunofluorescence assays were performed on the trabecular meshwork of eyes with open-angle glaucoma.
    • The assays specifically looked for immunoglobulins and complement components indicative of an antigen-antibody reaction.

    Main Results:

    • Assays for specific immunoglobulins in the trabecular meshwork were negative.
    • Complement components resulting from antigen-antibody reactions were not detected.

    Conclusions:

    • The study found no evidence to support an immunogenic mechanism in open-angle glaucoma.
    • The presence of gamma globulin and plasma cells does not appear to be linked to specific immune responses in this condition.
