Ocular migraines cause vision loss or blindness lasting less than an hour, along with or following a migraine headache. Experts sometimes call these episodes "retinal," "ophthalmic," or "monocular" (one eye) migraines.
This problem is rare. It affects about one out of every 200 people who have migraines. Some research suggests that in many cases, symptoms of ocular migraine are actually due to other problems.
Diagnosing ocular migraine requires a health care professional to rule out other conditions that can cause similar symptoms. Being able to describe the symptoms properly is important for helping your doctor determine whether you actually have an ocular migraine.
