Retinal migraine (sub-category of ocular
migraine) is a retinal disease accompanied by migraine headache and
typically affects only one eye.
Symptoms
Retinal Migraine involves migraine headache associated with transient monocular
visual loss (scotoma)
lasting less than 1 hour.[1] During
some episodes, the visual loss may occur with no headache and at
other times throbbing headache on the same side of the head as the
visual loss may occur, accompanied by severe light sensitivity
and/or nausea. After each episode, normal vision returns.
It may be difficult to read and dangerous to drive a vehicle
while retinal migraine symptoms are present.
Retinal migraine is a different disease than scintillating scotoma which is a
visual anomaly caused by spreading depression in the occipital
cortex, at the back of the brain, not in the eyes nor any component
thereof, such as the retinas.[2]
Diagnosis
The medical exam should rule out any underlying causes, such as
blood clot, stroke, or detached retina. A normal retina exam is
consistent with retinal migraine.[3]
Treatment
Treatment depends on identifying behavior that triggers migraine
such as stress, sleep deprivation, skipped meals, food
sensitivities, or specific activities. Medicines used to treat
retinal migraines include aspirin, other NSAIDS, and medicines that
reduce high blood pressure.[4]
Prognosis
More than half of reported cases of Retinal Migraine
subsequently experienced permanent visual loss in that eye from infarcts.[5]
