How Does Herpes Zoster Affect the Eye?
Herpes zoster commonly attacks the nerves around the eye, especially the nerve that supplies the upper eyelid and forehead. If the virus affects the nerves that go directly to the eyeball, it can cause serious eye problems, including corneal ulcers, inflammation and glaucoma. These problems may appear at the same time as the skin rash or weeks after the vesicles have disappeared. Lingering pain is the result of injured sensory nerves, which may remain overly sensitive for years after the attack.
