Herpes zoster rates are increasing among adults in the United States. Herpes zoster, also known as zoster and shingles, is caused by the reactivation of the varicella-zoster virus VZV , the same virus that causes varicella chickenpox. Physicians began to report that cases of herpes zoster were often followed by chickenpox in the younger people who lived with the shingles patients. Instead, VZV remains present in an inactive dormant state in dorsal root ganglia, the part of the spinal nerves responsible for sensations such as pain. Once the illness resolves, the virus remains dormant latent in the dorsal root ganglia.

In healthy individuals, formation of new lesions in the primary dermatome stops within 3 to 7 days, and crusting occurs within 2 weeks. In general, herpes zoster has no seasonal incidence and does not occur in epidemics. However, varicella can be lethal to individuals who are infected later in life or who have low immunity. Shingles symptoms usually correspond to the skin area or dermatome supplied by the affected sensory nerve roots. These patients generally require hospital admission for IV antiviral therapy. The risk of developing PHN is significantly higher in older adults greater than 50 years of age.
HZO iritis is frequently associated with high intraocular pressure. Report of 3 cases, Int. Thus, they are concerned that routine childhood varicella vaccination, recommended in the United States in , could lead to an increase in herpes zoster in adults due to reduced opportunities for being exposed to varicella. The most common complication of herpes zoster is postherpetic neuralgia PHN. Prodromal refers to the initial phase of an illness, the interval between the earliest symptoms and the appearance of a rash. In our case, the patient showed vesicles of the external ear and loss of taste sensation in anterior two-third of the tongue but facial palsy was not evident, thereby excluding the possibility of the abovesaid diagnosis. This is called zoster sine herpete and will present similar to the prodromal phase of herpes zoster without the visible rash ever coming out to the surface.
