“Ocular migraine” is a term used to cover several migraine subtypes that cause visual disturbances, including migraine with aura, retinal migraine, and ophthalmic migraine, among others.
During an ocular migraine episode, you may see flashing or shimmering lights, zigzagging lines, or stars. It may also cause blind spots in your field of vision.
An ocular migraine attack can interfere with your ability to perform tasks like reading, writing, or driving. Symptoms are temporary, and ocular migraine is typically not considered a serious condition.
The exact causes of ocular migraine are unknown. One theory is that a narrowing of arteries causes a temporary lack of blood flow to the eye and induces symptoms.
However, other factors may contribute to ocular migraine.
