Silent migraines are a medical oddity. How can you have a migraine "headache" without headache pain? The answer lies in the still unfolding mystery of migraine. WebMD explains what silent migraines are as well as their unusual visual symptoms, commonly called an aura.
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.
