What Is an Ocular Migraine?
6. Possible Causes
Researchers do not fully understand what causes this condition. One hypothesis is that abnormal electrical activity in the cortex of the brain may develop into an ocular migraine. Other studies have shown that fluctuations in estrogen can result in an increase of this type of visual disruption.
Some medical professionals think that ocular and classic migraines may be linked to the same causes. These include reactions to food substances and additives such as nitrates in processed meats, monosodium glutamate, aspartame, and caffeine.
