How can my doctor tell if I have HZO?

If you have HZO, you will probably have a rash that looks like chickenpox, usually on one side of your face or forehead. Besides examining you, your doctor will not need to do any additional tests to see if you have HZO. Sometimes herpes simplex infections can resemble HZO. However, the patterns of the rashes are different and your doctor will be able to tell them apart.

How often is the eye involved?

The eye itself is affected in 10% of patients. Your doctor will examine you to see if your eye is affected by HZO. If it is, you may need to see an ophthalmologist (a doctor who specializes in treating eyes) for further treatment.
