 | When we think of a migraine, we usually associate it with a headache. But migraines can vary in symptoms and triggers. For example, ocular migraines are a subtype that involves visual changes and disturbances. A range of visual changes can develop, which may or may not accompany a headache. Ocular migraines can vary in frequency and severity. Learning more about how to manage the condition can help you develop treatment and prevention strategies. |
Forms
Everyone may experience symptoms of ocular migraines differently. There are also a couple of types, including:
Ophthalmic migraine: This is a visual aura that manifests in many different ways and does not have a headache and typically lasts about 20 minutes. It is like a classic migraine which has the aura but does not have the headache afterwards.
Migraine with an aura: This is a common form of migraine. According to the American Migraine Foundation, about 20 to 30 percent of people with migraines have visual auras. The aura tends to only last a short time and may occur with or without head pain. In many cases, the aura occurs before head pain starts and acts as a warning that a headache is about to start.
