Ocular migraines are a type of migraine that involves attacks of visual disturbances that affect one eye and migraine headaches. The visual issues are temporary and can include a blind spot in the central area of vision, colored or flashing lights, and areas of lessened vision. The exact cause of ocular migraines is not entirely understood, but researchers have identified certain triggers that may include stress, hormones, bright or flickering lights, loud sounds, and certain foods. Other possible causes include reduced blood flow or spasms of blood vessels in the retina or behind the eye. Genetics may also play a role, as there is a genetic link to migraines. Ocular migraines can start as early as 7 years of age, but most people start experiencing them in their 20s, with a peak age of 40. Treatment involves avoiding triggers with lifestyle changes and medication. If you experience ocular migraines, it is important to see an eye doctor as soon as possible to rule out other, more serious, causes.
