Most people know migraines are severe headaches. However, few are familiar with ocular migraines, which are relatively rare. The symptoms and experience of this headache can be disturbing if you’re unfamiliar with this condition. Here, Dr. Kenneth Houchin, an eye doctor in Nevada, explains what distinguishes an ocular migraine.

Causes & Symptoms 

Ocular migraines typically last for 20 to 30 minutes and involve significant visual disturbances. They can affect one or both eyes and may or may not be accompanied by a headache. The presentation varies from person to person but might include blind spots, flashing or flickering lights, or patches of blurriness surrounded by wavy lines.

Often, the disturbances start out small and expand in size gradually until your normal vision returns. Other symptoms include nausea, vomiting, and sensitivity to lights and sounds. 

Researchers are not entirely sure what causes ocular migraines, but they suspect there is a genetic component. They also believe the neurological conditions that cause standard migraines can contribute to ocular migraines. Another theory is that visual disturbances arise as the result of blood vessel spasms or overactive nerve cells in the retina.

Treatments & Prevention

Because the medical community is still unsure what causes ocular migraines, there is no standard treatment. Fortunately, these disturbances are harmless and typically resolve themselves within half an hour. If you are behind the wheel or performing some other visually demanding task when you experience an ocular migraine, stop and try to relax until the disturbances pass. 

As for prevention, experts recommend avoiding the same kinds of triggers that cause standard migraines, like cigarette smoke, perfumes, glaring lights, sleep deprivation, artificial sweeteners, caffeine, and red wine. Some medications may also help. For the most effective prevention, though, you first need an accurate diagnosis from your eye doctor.

If you suffer from temporary visual disturbances, they could be ocular migraines. However, an eye doctor should rule out more serious conditions with a thorough exam.
