Acute Orbital Syndrome in Herpes Zoster Ophthalmicus: Clinical Features of 7 Cases

Purpose: To report a series of patients with herpes zoster ophthalmicus and associated acute orbital syndrome with corresponding radiographic findings. Methods: Medical records of 7 patients with herpes zoster ophthalmicus with acute orbital findings were reviewed. Clinical presentation, radiography, and treatment outcomes were assessed. Results: One man and 6 women with a median age of 70 years (range 47–84) presented with herpes zoster ophthalmicus with acute clinical orbital signs. Two of the 7 patients had compromised immune systems, with 1 patient having chronic lymphocytic leukemia and another infected with human immunodeficiency virus. Clinical orbital findings included proptosis, blepharoptosis, ophthalmoplegia, diplopia, and visual loss. Orbital imaging detailed such findings as myositis in all 7 patients, dacryoadenitis in 2 patients, and optic nerve sheath enhancement in 1 patient. Treatment with intravenous acyclovir was universal in all 7 patients and in 2 cases systemic corticosteroids were also administered. Orbital signs improved in all patients over several months. Conclusions: Herpes zoster ophthalmicus can rarely cause an acute orbital syndrome and the authors present what may be the largest series of such patients to date. Herpes zoster ophthalmicus can affect various orbital structures including the lacrimal gland, extraocular muscles, cranial nerves and optic nerve sheath. A careful clinical examination and detailed orbital radiography are critical in proper diagnosis and treatment of such patients. Improvement of symptoms and signs with antiviral therapy can be expected; however, complete resolution does not always occur. The role of systemic steroids in treatment of orbital disease is yet to be determined.
