    Lymphocytes from open-angle glaucoma patients are not more sensitive to glucocorticoids in vitro. Lymphocyte response to corticosteroids appears to be a general phenomenon, not specific to glaucoma.

    Area of Science:

    • Immunology
    • Ophthalmology

    Background:

    • Open-angle glaucoma is a leading cause of irreversible blindness.
    • Identifying reliable biomarkers for glaucoma diagnosis is crucial.
    • Glucocorticoid sensitivity of lymphocytes has been proposed as a potential diagnostic marker.

    Purpose of the Study:

    • To investigate if lymphocytes from open-angle glaucoma patients exhibit differential sensitivity to glucocorticoids in vitro compared to healthy individuals.
    • To explore the relationship between glucocorticoid-induced lymphocyte inhibition and lymphocyte activation.

    Main Methods:

    • In vitro assessment of lymphocyte behavior in the presence of varying concentrations of glucocorticoids.
    • Measurement of lymphocyte membrane activation using phytohemagglutinin.

    Main Results:

    • Lymphocytes from open-angle glaucoma patients did not show increased sensitivity to glucocorticoids compared to normal subjects.
    • The extent of glucocorticoid-induced inhibition correlated with the degree of lymphocyte activation by phytohemagglutinin.
    • The observed phenomenon was not specific to open-angle glaucoma.

    Conclusions:

    • The in vitro behavior of lymphocytes in the presence of glucocorticoids does not serve as a specific diagnostic marker for open-angle glaucoma.
    • Lymphocyte response to glucocorticoids is likely a general biological phenomenon influenced by activation levels.
