Herpes zoster (or simply zoster), commonly known as shingles and sometimes referred to as zona, is a viral disease characterized by a painful skin rash with blisters in a limited area on one side of the body, often in a stripe.
Varicella zoster virus can become latent in the nerve cell bodies and less often in non-neuronal satellite cells of dorsal root, cranial nerve or autonomic ganglion, without causing any symptoms.

A corneal ulcer (or ulcerative keratitis) is referred to as an infective condition of the cornea, with an open sore that overlies the iris, the colored part of the eye. The initial infection with varicella zoster virus (VZV) causes the acute (short-lived) illness chickenpox which generally occurs in children and young people.

Years or decades after a chickenpox infection, the virus might break out of nerve cell bodies and travel down nerve axons to cause viral infection of the skin in the region of the nerve.
Antiviral drug treatment can reduce the severity and duration of herpes zoster if a seven- to ten-day course of these drugs is started within 72 hours of the appearance of the characteristic rash.
The virus might spread from one or more ganglia along nerves of an affected segment and infect the corresponding dermatome (an area of skin supplied by one spinal nerve) causing a painful rash. Although the rash usually heals within two to four weeks, some sufferers experience residual nerve pain for months or years, a condition called postherpetic neuralgia. Children with deficiencies of Vitamin A stand at high chances of getting corneal ulcer and even lifelong blindness, particularly in developing countries.

Exactly how the virus remains latent in the body, and subsequently re-activates is not understood. Corneal ulcers are very painful owing to nerve exposure, and may also cause tearing, squinting and loss of vision to the eye. There could also be symptoms of anterior uvetis like small pupil, aqueous flare and redness of the eye.
