An ocular migraine, also known as an ophthalmic migraine or retinal migraine, is a painless and temporary disturbance in vision that affects either one or both eyes. Ocular migraines usually resolve, without medication, within 20 to 30 minutes from the start of the occurrence. If the ocular migraine is accompanied by a throbbing headache, then it is classified as a migraine with an aura.
