Detailed Answer:
Ocular migraines are really fairly rare and some research suggests that for many who are diagnosed with this, the symptoms are actually due to other problems.

It is not fully known what causes ocular migraines, but it is believed that they are caused by spasms in blood vessels in the retina of the eye. It may also be possible that there are changes in the nerve cells of the retina.

Some of the things that seem to be associated with bringing on ocular migraines include smoking, uncontrolled high blood pressure, stress (physical such as high heat, or emotional), birth control pills, exercise, dehydration, high altitudes.

Treatment can include one or more of the following medications:

Beta Blockers - these are blood pressure/heart medicines that can help prevent the blood vessels from narrowing/going into spasm.

Aspirin

Calcium channel blocker, such as nifedipine.

Drugs used to prevent seizures, such as depakote. Anti epilepsy medications such as this are also used for regular migraines.

Tricyclic antidepressants, such as amitriptyline or nortriptyline. This type of antidepressant is also commonly used for regular migraines.

Ocular migraines should really only be diagnosed by an ophthalmologist or neurologist.

I hope this information helps.
