A visual aura is a disturbance in vision that is often experienced by people before they have a migraine headache. It can also occur even without a headache. The appearance of a visual aura varies significantly from person to person. For example, some people may see either bright or black spots, white zig-zag lines or even bright colours. A visual aura can last anywhere from 5-60 minutes and when prolonged can interfere with activities such as driving and reading.
The treatment of visual aura is similar to that of migraine. If you have visual aura that impacts your life, make an appointment today to discuss treatment. Of course, visual changes can occur for many reasons, and you should see your doctor if concerned.
