Many major brain problems can cause both headaches and eye problems. For example, brain tumors may not only cause headaches but also cause double vision by pressing on some of the nerves that control eye movement. They may damage the optic nerve, either by pressing directly on the optic nerve fibers as they pass through the brain or by raising the fluid pressure inside the head, which in turn applies pressure to the optic nerves. An aneurysm, by bleeding suddenly, may cause similar problems. Nerve palsies caused by the shutdown of small blood vessels, as often seen in diabetics, are sometimes accompanied by pain around the involved eye. Some eye medications, such as pilocarpine, a drug used to treat glaucoma,may cause a headache, although in the case of pilocarpine, it is often termed a brow ache. Fortunately, most headaches are not caused by serious problems such as brain tumors or aneurysms.But any new headache, especially one that persists or is different in quality from a person’s “usual”headaches, deserves medical evaluation.
