[Diagnostics and management of herpes zoster ophthalmicus].

Herpes zoster (HZ, shingles) represents the secondary manifestation of an infection with varicellazoster virus (VZV). A reactivation of dormant VZV in the ophthalmic branch of the fifth cranial nerve leads to ophthalmic HZ (HZO). The predominantly older and immune compromised patients often present with eye involvement (approximately 50%) as well as characteristic skin changes. Clinical manifestations include the cornea and conjunctiva but anterior uveitis and (rarely) acute retinal necrosis may also occur. Associated sensory symptoms that range from paresthesia to severe pain may severely affect the quality of life. Particularly in immunocompromised and/or elderly patients, HZO is associated with complicated courses. Systemic antiviral treatment and an adequate pain medication are the mainstay of the recommended management. The present article provides an overview of the contents of the current consensus-based European guidelines on the management of HZ with a specific focus on HZO.
