Herpes Zoster - Causes, Symptoms & Treatment

Shingles (Herpes Zoster) is a painful, blistering rash caused by the chickenpox (varicella) virus, which affects only a limited area of skin, and makes you feel surprisingly tired, run down, and even depressed. Shingles incidence is high in the elderly , as well as in any age group of immunocompromised patients. Herpes zoster may be associated with a secondary bacterial infection (typically streptococcal or staphylococcal) of the vesicular rash.

Herpes zoster involving the second branch of the trigeminal nerve may be associated with conjunctivitis, keratitis, corneal ulceration, iridocyclitis, glaucoma, and blindness Herpes zoster can cause several problems with the eye and surrounding skin that may have long term effects. Inflammation and scarring of the cornea , along with conjunctivitis and iritis are typical problems that require treatment.  In some cases, the retina and optic nerve are involved. 

Eye problems caused by severe or chronic outbreaks of herpes zoster may include:  glaucoma, cataract, double vision, and scarring of the cornea and eyelids.
