What Is an Ocular Migraine?
1. Definition
Ocular migraine can be a confusing term because people use it to signify different vision-loss events. Sometimes it can occur prior to or along with a migraine headache. If this is the case, other symptoms including pain will also be present. Very often, however, with an ocular migraine you will have no pain whatsoever and no discomfort beyond that which obscured vision may induce.
An ocular migraine is thought to occur when the blood vessels in the back of the eye swell, causing temporary visual symptoms of vibrating patterns and lights that make it difficult to see well. Although it is not generally considered to be serious, it can be disruptive, so managing the occurrences is helpful.
