Few of them find it difficult to differentiate the flashing lights in regular migraine and the blindness or vision disturbances in one of the eye due to ocular migraines.
The actual cause for ocular migraines are still unknown. Some of the factors thought to cause this condition include blood vessel spasms and nerve cell changes in the retina. Ocular migraines may be triggered by certain foods like aged cheeses, caffeine, red wine, chocolate and smoked meats. Food additives, like monosodium glutamate and artificial sweeteners may also initiate ocular migraines for some. Other triggers of this migraine include cigarette smoke, strong smelling perfumes, flickering lights, and stress. People with ocular migraines have a higher risk of permanent vision loss at a later stage. This type of migraine often starts in puberty, but is most commonly seen in the age group between 30-years-old and 40-years-old. Women have a higher risk for developing ocular migraines, when compared to men.

Since migraines may be triggered by food, it would be helpful if one keeps a record of his or her diet.
