A migraine headache that involves the eyes is known as an ocular migraine. Unlike a typical migraine, which usually causes excruciating pain, an ocular migraine often occurs with no pain at all. Rather, it affects one’s eyesight with an array of visual disturbances. An ocular migraine of this type is sometimes called a silent migraine.
A person experiencing an ocular migraine might see or experience spots, shimmering points of light, zig-zagging or wavy lines, blurry or double vision, or temporary vision loss.
Generally, an ocular migraine lasts less than one hour, with about a half hour being very common. It usually goes away as suddenly as it came on.
The causes of ocular migraines are not clear and vary from person to person. Certain foods, stress or changes in hormones all have been linked to ocular migraines.
Unfortunately, a full-blown, painful migraine headache might follow the visual disturbances of an ocular migraine.
See a doctor to rule out any serious conditions.
