Headache behind right eye, reduced vision. Aura?

Migraine. Could be an ocular migraine. Is there a family history of migraine or personal hx of other migraine variants? Check your blood pressure to be sure this isn't the cause. The reduced vision is very concerning. It may just be migraine but you could have increased intraocular pressure (glaucoma), or it could be an indication of something intracranial even more concerning. You need evaluation.
