Ocular migraine is a term which may have different meanings to different physicians. Many times migraineurs will have just the visual warning signs or aura of their migraine attack without the headache. This occurs more frequently as one gets older and can be a frightening phenomenon. This is also referred to as “acephalgic” migraine, or migraine aura without headache.
Some physicians refer to ocular migraine as retinal migraine, where there are repeated attacks of one-sided blind spots or blindness lasting less than an hour and associated with a headache.
It is important to rule out eye disease or a disorder of the blood vessels leading to the eye as possible causes.
