What Causes Ocular Migraines. A migraine that involves visual disturbance is called an ocular migraine. Ocular migraines can develop with or without the accompanying pain of a classic migraine. During an ocular migraine, or migraine with aura, you may see flashing or shimmering lights, zigzagging lines, or stars. Some people describe psychedelic images. It may also cause blind spots in your field of vision. Of people who report having migraines, one out of every five experiences this aura (Womenshealth.gov, 2012). Ocular migraines can interfere with your ability to perform tasks like reading, writing, or driving.
