    Open-angle glaucoma patients show higher rates of parasympathetic neuropathy. This finding suggests a link between autonomic dysfunction and glaucoma, potentially explaining why autonomic medications may help treat glaucoma.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Cardiovascular Physiology

    Background:

    • Glaucoma is a leading cause of irreversible blindness.
    • Autonomic dysfunction is increasingly recognized as a potential comorbidity in various systemic diseases.
    • The role of systemic autonomic nerve function in primary open-angle glaucoma (POAG) remains incompletely understood.

    Purpose of the Study:

    • To investigate systemic autonomic nerve function in patients with POAG.
    • To compare autonomic function between POAG patients and healthy controls.
    • To explore the potential association between autonomic neuropathy and POAG.

    Main Methods:

    • Systemic autonomic nerve function was assessed using standardized cardiovascular reflex tests.
    • Sixty-seven patients with POAG and 76 age- and sex-matched healthy controls participated.

  • Tests included responses to stimuli evaluating parasympathetic and sympathetic functions.

    • Main Results:

    • Parasympathetic neuropathy was diagnosed in 37.3% of POAG patients.
    • Only 2.6% of the control group exhibited parasympathetic neuropathy.
    • A significant association was found between autonomic neuropathy and POAG.

    Conclusions:

    • A higher prevalence of parasympathetic neuropathy exists in POAG patients compared to controls.
    • The demonstrated association provides a potential rationale for using autonomic medications in glaucoma management.
    • Autonomic dysfunction may be a significant factor in the pathogenesis or progression of POAG.
