Is Herpes Simplex related to herpes zoster?
Herpes simplex virus types 1 and 2 and varicella–zoster virus are unique members of the Herpesviridae family, as they can infect both skin and nerves and develop latent infection within the dorsal root and trigeminal ganglia. Infection with these viruses is common and causes a wide range of clinical syndromes.
Which nerve is affected in herpes zoster Ophthalmicus?

What is herpes zoster Ophthalmicus?
Herpes zoster ophthalmicus occurs when reactivation of the latent virus in the trigeminal ganglia involves the ophthalmic division of the nerve. The virus damages the eye and surrounding structures by secondary perineural and intraneural inflammation of sensory nerves.
Are herpes simplex and herpes zoster related?
Is herpes zoster Ophthalmicus an emergency?
This manifestation is termed herpes zoster ophthalmicus (HZO). HZO is considered an ophthalmologic emergency, as sequelae often include severe chronic pain and vision loss. In order to ensure proper follow up and to minimize morbidity, the accurate and timely diagnosis of HZO in the ED is extremely important.
