Ocular Migraine Prevention

The first step to preventing migraines is to avoid triggers. These often include:

  • Stress
  • Smoking
  • High blood pressure
  • Hormonal birth control pills
  • Exercise
  • Bending over
  • High altitude
  • Dehydration
  • Low blood sugar
  • Excessive heat

Although dietary triggers – such as caffeine, alcohol, and artificial sweeteners -- can cause other types of migraines; they seem less likely to trigger ocular migraines.

Understanding Headache -- Treatment

Most headaches can be diagnosed by a medical history and physical exam. Rarely, to rule out other causes of headaches such as an aneurysm, tumor, or structural abnormality, a doctor may call for vision tests, X-rays, a CT scan, MRI, a lumbar puncture, or an EEG.

Medications can also prevent ocular migraines. Calcium-channel blockers, such as Cardene and Calan, are the most commonly used drugs. They work by opening up the blood vessels. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin are also sometimes used. Less often, your doctor may prescribe drugs used to prevent blood clotting, depression, and epilepsy.

A device is also an option. Cefaly is the first FDA-approved device for preventing migraines in people over age 18. The portable headband-like device gives electrical impulses on the skin at the forehead. This stimulates a nerve associated with migraine headaches. Cefaly is used once a day for 20 minutes, and when it's on you'll feel a tingling or massaging sensation.
