Researchers are studying the relationship between glaucoma and migraines.
At the 2010 American Academy of Ophthalmology (AAO) – Middle East-Africa Council of Ophthalmology (MEACO) Joint Meeting in Chicago Russian researcher Yury S Astakhov, MD, PhD presented his work with people susceptible to migraines and how their day- and at night-time blood pressure levels may be related to the onset of glaucoma.
According to Dr. Astakhov, “We conclude that low diastolic blood pressure at night is a possible risk factor for glaucoma in patients with migraine.”
Migraine is a known risk factor for open-angle glaucoma, especially in the development of normal tension glaucoma in which the optic nerve becomes damaged even though there is no elevation in eye pressure.

Researchers tie blood pressure and ocular perfusion pressure to glaucoma
Although intraocular pressure (IOP) is considered a primary risk factor for the development of glaucoma, there is evidence to suggest that glaucoma may continue to progress despite lowering patients’ IOP to targeted levels.
Several recent studies point to vascular risk factors in the development of glaucoma. This new research indicates that blood pressure (BP) and ocular perfusion pressure have become increasingly important in understanding and treating glaucoma.
Although doctors cannot currently visualize ocular blood flow directly, they can easily measure glaucoma patients’ BP and IOP to calculate their ocular perfusion pressure and quantify the vascular changes.
An article published in the British Journal of Ophthalmology explores the relationships between BP and IOP, BP and glaucoma, and perfusion pressure and glaucoma. Study authors suggest that ocular perfusion pressure and its fluctuation may be parameters that need to be measured in the treatment of glaucoma patients.
