B02.3: Zoster ocular disease

Shingles is caused by certain pathogens. These pathogens are viruses. These viruses also cause chickenpox. Once someone has been infected by the chickenpox viruses, the viruses remain hidden in the body for a long time. Sometimes the viruses may break out again after several years and cause shingles. Then, with shingles, small red blisters and pustules form on a particular part of the skin. The blisters and pustules usually stay in one half of the body and form a belt pattern. The part of the skin that is affected can be very sore. You can also get a high temperature and headaches and feel very sick.

The shingles has spread to the half of your face around the eye. This can inflame the eye or eyelid at the site affected. The eye or eyelid can then become very painful and watery. Your vision might also be affected.
