Summary
Migraine patients frequently exhibit visual field defects resembling glaucoma. This study suggests a link between migraine and glaucomatous optic neuropathy, recommending visual field screening for migraineurs.
Area of Science:
- Ophthalmology
- Neurology
Background:
- Migraine is a common neurological disorder.
- Glaucomatous visual field defects are typically associated with elevated intraocular pressure (IOP).
Purpose of the Study:
- To investigate the prevalence of glaucomatous visual field (VF) defects in patients diagnosed with migraine.
- To explore potential correlations between migraine characteristics and VF defects.
Main Methods:
- Seventy-seven migraine patients underwent detailed ophthalmological examinations and computerized VF analysis.
- Patient history included migraine frequency, pain characteristics, aura, and family history of glaucoma.
- Statistical comparisons were made between patients with and without glaucomatous-like VF defects.
Main Results:
- Glaucomatous-like VF defects were identified in 62.3% of migraine patients, all with normal IOP.
- Older age and a later age of migraine onset were associated with these defects.
- Migraine attacks occurring once a month or less frequently increased the risk of developing glaucomatous-like VF defects.
Conclusions:
- A potential relationship exists between migraine pathophysiology, visual field defects, and glaucomatous optic neuropathy.
- Visual field screening is recommended for migraine patients to detect normal-tension glaucoma.
