Eyelid herpes zoster is a disease of the eyelid skin caused by varicella-zoster virus infection of the trigeminal nerve.
The main clinical manifestation is the appearance of clusters of small, clear blisters on the eyelid skin arranged in bands that do not extend beyond the middle boundary of the face and nose. As the disease progresses, the blister fluid becomes cloudy, ruptures and eventually dries and crusts over. The disease usually lasts about 2 weeks, and after the scabs have fallen off, permanent scarring and hyperpigmentation may form.
Patients may also experience severe neuralgia that persists for months after the disease has healed.
