causes of headaches retina eye stops working
Migraines With Vision Problems and Vertigo Vision problems usually start 20 minutes to an hour before the headache. Even if you don't get an aura to warn you, the headache itself may cause vision trouble. A retinal migraine causes a variety of visual symptoms, possibly blindness in one eye, before and during the headache. Fortunately, these problems go away with it, but permanent vision loss may be a complication of this type of migraine.
