Retinal migraine
Retinal Migraine
Retinal migraine (pronunciation: /rɛˈtaɪnəl ˈmaɪˌɡreɪn/) is a rare condition often confused with other types of migraine. It is characterized by temporary, partial or complete loss of vision in one eye, accompanied or followed by a headache.
Etymology
The term "retinal migraine" is derived from "retina" (from Latin retina, meaning "net") and "migraine" (from French migraine, from Late Latin hemicrania, meaning "pain in one half of the head").
Symptoms
The primary symptom of a retinal migraine is a temporary loss of vision in one eye. This can last anywhere from a few minutes to an hour. The vision loss is usually followed by a headache, which can last from a few hours to a few days. Other symptoms may include nausea, vomiting, and sensitivity to light and sound.
Causes
The exact cause of retinal migraines is unknown. However, it is believed to be related to changes in the blood vessels of the eye. Certain triggers such as stress, dehydration, caffeine withdrawal, and certain foods can also cause a retinal migraine.
Diagnosis
Diagnosis of retinal migraine can be challenging due to its rarity and the transient nature of the symptoms. It is often diagnosed based on the patient's medical history and a thorough eye examination. Other conditions such as stroke, detached retina, and optic neuritis must be ruled out.
Treatment
Treatment for retinal migraine focuses on relieving symptoms and preventing future attacks. This can include medications to treat the headache and nausea, as well as lifestyle changes to avoid known triggers. In some cases, preventive medications may be prescribed.
