MIGRAINE AND GLAUCOMA - AN EPIDEMIOLOGIC SURVEY OF FRENCH OPHTHALMOLOGISTS

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