What Is an Ocular Migraine?
5. Frequency and Duration
You may only experience an ocular migraine once or twice in your lifetime. Usually the occurrences are spaced out by weeks, months, or even years. Some studies indicate that the frequency of ocular migraines tends to increase with age.
Although they may appear at any time, the visual disturbances are generally very short in duration. Usually lasting from 10 to 20 minutes, all symptoms resolve completely in less than an hour. When they last more than an hour, a migraine headache is typically also involved.
