Definition
Retinal migraines (more properly retinal vasospasm) were defined in 1988 by the International Headache Society (IHS) as at least two attacks of fully reversible, transient monocular visual loss or disturbances associated with migraine headache. The complete diagnostic definition, as outlined by the IHS is detailed in the “Diagnostics” section below. However, recent literature challenges the notion that monocular visual loss is physiologically associated with migraine headaches. Instead, some researchers propose that “presumed retinal vasospasm” with or without associated migraine would be a more accurate diagnosis for most patients.
Etiology
The pathophysiology of retinal migraine/vasospasm remains controversial. The two main criteria are monocular visual disturbance and migraine headache. Some cases of retinal vasospasm however do not have the migraine headache (acephalgic migraine equivalent)....
