    Patients with low-tension glaucoma experience headaches more frequently than other groups, particularly elderly individuals. This finding suggests a potential link between low-tension glaucoma and conditions like migraine, which has therapeutic implications.

    Area of Science:

    • Ophthalmology
    • Neurology

    Background:

    • Glaucoma is a group of eye conditions that damage the optic nerve.
    • Headaches are a common symptom with various underlying causes.
    • Low-tension glaucoma (LTG) is a form of glaucoma where optic nerve damage occurs despite normal intraocular pressure.

    Purpose of the Study:

    • To investigate the prevalence of headaches in patients with different types of glaucoma and ocular hypertension.
    • To explore the potential association between headaches, particularly migraine features, and low-tension glaucoma.

    Main Methods:

    • A standardized headache questionnaire was administered to 54 LTG patients, 182 primary open-angle glaucoma (POAG) patients, 126 ocular hypertension (OHT) patients, and 493 normal subjects.
    • Headaches were assessed for presence and features suggestive of migraine (unilateral, nausea/vomiting, visual prodromata).

  • Prevalence rates were compared across the different study groups, with a specific focus on elderly participants.

    • Main Results:

    • Patients with low-tension glaucoma reported headaches more frequently than POAG patients, OHT patients, and normal subjects.
    • The prevalence of headaches in elderly LTG patients (86%) was significantly higher compared to elderly normal subjects (64%) and elderly OHT patients (59%).
    • Headache features consistent with migraine were also more common in the LTG group.

    Conclusions:

    • Headaches are significantly more prevalent in patients with low-tension glaucoma, especially in the elderly population.
    • The findings suggest a potential etiologic link between low-tension glaucoma and migraine, possibly related to ischemic mechanisms.
    • Further research into this association may offer new therapeutic strategies for both conditions.
