Increased plasma cortisol levels in ocular hypertension

B Schwartz, J M Seddon

    Archives of Ophthalmology (Chicago, Ill. : 1960)
    |October 1, 1981
    PubMed
    Summary

    Elevated plasma cortisol levels correlate with higher ocular pressure in patients. This finding was linked to blood pressure, suggesting a connection between cortisol, eye pressure, and cardiovascular health.

    Area of Science:

    • Endocrinology
    • Ophthalmology
    • Cardiovascular Science

    Background:

    • Ocular pressure is a key factor in glaucoma and other eye conditions.
    • Plasma cortisol, a stress hormone, has been implicated in various systemic conditions.
    • The relationship between ocular pressure and systemic factors like cortisol requires further investigation.

    Purpose of the Study:

    • To investigate the association between plasma cortisol levels and ocular pressure.
    • To determine if ocular pressure is correlated with systemic factors, specifically blood pressure.
    • To explore the relationship between cortisol, ocular pressure, and blood pressure.

    Main Methods:

    • Plasma cortisol levels were measured in patients with elevated and normal ocular pressure.
    • Ocular pressure was recorded at the time of blood sampling.
    • Blood pressure (systolic and diastolic) was measured in both patient groups.

    Main Results:

    • Patients with elevated ocular pressure exhibited significantly higher plasma cortisol levels compared to those with normal ocular pressure.
    • Higher plasma cortisol levels were directly associated with higher ocular pressure readings at the time of sampling.
    • Elevated plasma cortisol and ocular pressure were both significantly correlated with higher systolic and diastolic blood pressure.

    Conclusions:

    • Elevated plasma cortisol levels are closely linked to ocular pressure at the time of sampling.
    • The findings suggest a potential interplay between the endocrine system (cortisol), ocular hemodynamics, and cardiovascular regulation.
    • Further research is warranted to elucidate the mechanisms underlying this association and its clinical implications for eye health.
