Migraine and glaucoma: an epidemiologic survey of French ophthalmologists.

Glaucoma is a common ocular disorder; a high intraocular pressure is observed in the majority of glaucoma (HIOPG) cases, but some patients have low-tension glaucoma (LTG). In the literature, some works link LTG and migraine, which is speculative of a potential role of a vasospastic factor or diathesis common to migraine and LTG. Using a standardized questionnaire based on International Headache Society (IHS) criteria, we investigated 954 glaucoma patients; 320 (33.5%) described a headache (migraine or tension-type headache) and 240 (25.1%) presented the IHS criteria for migraine. Migraine prevalence was not significantly different between HIOPG and LTG patients (22.8% and 32%, respectively) in this study.
