    Pupil cycle time is prolonged in patients with closed-angle glaucoma. This finding suggests a potential link between glaucoma and parasympathetic nervous system dysfunction.

    Area of Science:

    • Ophthalmology
    • Neuroscience

    Background:

    • Closed-angle glaucoma is a significant cause of vision loss.
    • Pupillary abnormalities may indicate underlying neurological conditions.

    Purpose of the Study:

    • To investigate pupil cycle time (PCT) in patients with closed-angle glaucoma.
    • To explore the association between PCT and systemic parasympathetic neuropathy.

    Main Methods:

    • Fellow eyes of 118 closed-angle glaucoma patients and 70 controls were analyzed.
    • Pupil cycle time was measured and pupillary oscillation was assessed.

    Main Results:

    • Significantly prolonged pupil cycle time was observed in glaucoma patients (p < 0.001).
    • Absent pupillary oscillation was more prevalent in the closed-angle glaucoma group (p < 0.001).

    Conclusions:

    • Closed-angle glaucoma is associated with prolonged pupil cycle time.
    • Findings suggest a potential link between closed-angle glaucoma and parasympathetic neuropathy.
