Migraine and Ocular Pain in “Glaucoma Suspect”

Abstract

A relationship between glaucoma and migraine has been hypothesized by some authors, but not confirmed by others. We studied the prevalence and features of migraine and ocular pain in 460 “glaucoma suspect” patients (with ocular hypertension, but without optic disc and visual field abnormalities) and 460 controls. A higher prevalence of migraine was found in patients (13%), particularly in women (17%), than in controls (7%). At the time of the interview, migraine was still active in 68% of the patients and had decreased in the remaining 32% (prevalently those not being treated for ocular hypertension), whereas it had ceased in 52% of controls. Attacks of “ocular pain” of mild and moderate intensity were found to occur in 51% of the patients with both “glaucoma suspect” and migraine, in almost all who were not taking treatment for ocular hypertension. “Ocular pain” was time-related to the history of glaucoma. Changes in intraocular pressure may play a role in the interaction between “glaucoma suspect”, migraine, and ocular pain.
