Herpes zoster ophthalmicus

An acute case of herpes zoster ophthalmicus with ophthalmoplegia

Herpes zoster ophthalmicus (HZO) with oculomotor nerve involvement is rare, even rarer as an acute presentation rather than sequelae of HZO. In this paper we present a case of cutaneous HZO in which our patient's initial presentation was one of complete ophthalmoplegia.

Ophthalmoplegia secondary to herpes zoster ophthalmicus

An 80-year-old Caucasian woman had been diagnosed with right herpes zoster ophthalmicus 2 ½ weeks before presentation to our department. Ten days after stopping oral aciclovir, she presented with periorbital pain, visual loss, ptosis and complete ophthalmoplegia. On examination, visual acuity in her right eye was hand movements, with a relative afferent pupillary defect and 2 mm proptosis. MRI demonstrated contrast enhancement within the orbit extending into the apex, suggestive of an inflammatory process. Oral treatment was started with oral aciclovir and corticosteroids for 2 months, when she had resolution of the optic neuropathy and ophthalmoplegia. Vision recovered to 6/9 and repeat neuroimaging revealed regression of the inflammatory process.

Varicella zoster viral disease

Herpes zoster is cause of considerable morbidity, especially among elderly patients, with a suggestion of a slight increase in incidence among female patients. Substantial research on the biology of the varicella zoster virus has led to advances in our knowledge of the pathophysiology of the disease along with more successful therapy for the acute episodes of herpes zoster. Ophthalmic zoster is more common than zoster in other cranial nerves and is associated with pronounced suffering. This article reviews the epidemiology, biology, and latency of herpes zoster, discusses the pathophysiology of the disease, and describes treatment options with antivirals and corticosteroids. The pathophysiology and treatment options for postherpetic neuralgia are also addressed. The varicella vaccine is now available, and initial results suggest that this may lessen the effect of herpes zoster in the future.
