Jan 1, 2020 · Although the majority of HZ cases present along truncal dermatomes, viral reactivation along the trigeminal nerve is possible, resulting in herpes zoster ophthalmicus (HZO).

Herpes Zoster Ophthalmicus (HZO), commonly known as shingles, is a viral disease characterized by a unilateral painful skin rash in one or more dermatome distributions of the fifth cranial nerve (trigeminal nerve), shared by the eye and ocular adnexa.

Herpes zoster most frequently involves the chest, abdomen, face or genitals. The distribution corresponds to the distribution of the nerve (dermatome) that has been affected. The disease does not cross the midline, but two adjacent dermatomes on the same side can be involved.

Aug 14, 2023 · Herpes zoster results from reactivation of the latent VZV within a sensory nerve ganglion, often presenting decades after the initial infection. The disease typically presents as a unilateral maculopapular or vesicular rash in a single dermatomal distribution.

Herpes zoster (HZ, or shingles) typically manifests as unilateral pain in a dermatomal distribution accompanied by a vesicular rash. Herpes zoster usually occurs in older adults and results from reactivation of the latent VZV within the sensory spinal or cerebral ganglia.

Most patients with herpes zoster oph-thalmicus present with a periorbital vesicular rash distributed according to the affected dermatome. A minority of patients may also develop...

Nov 18, 2012 · Compared to the number of latently infected neurons, reactivation of VZV is a rare event. it occurs in the sensory ganglia of the clinically affected dermatomes. HZO corresponds to a reactivation in the trigeminal ganglia.

Herpes zoster ophthalmicus (HZO) is due to reactivation of the varicella-zoster virus along the ophthalmic branch of the trigeminal nerve resulting in a characteristic painful, vesicular rash along the dermatome.
