Ocular migraines can cause symptoms related to the common or classic migraine headaches. In fact, ocular migraines generally occur in young adults who have had a previous history of common migraines, but can occur at any age. Patients may experience an ocular migraine without headache symptoms.
Symptoms of an ocular migraine often include a dark area or shimmering area or other visual disturbance which starts centrally and moves off to the side. This usually can last 10-60 minutes. Another common symptom is increased sensitivity to bright lights.
Generally, there are no serious ocular complications caused by ocular migraines. Treatment in most instances is not necessary unless the ocular migraine is linked to the common migraine and severe headaches occur.
