Ocular Manifestations of Herpes Zoster Ophthalmicus

ABSTRACT

PURPOSE: To analyze ocular manifestations of herpes zoster ophthalmicus and evaluate risk factors and complications affecting visual acuity. METHODS: Ocular, cutaneous, and systemic findings were analyzed retrospectively from the medical records of 81 patients, admitted between 1994 and 2007, to the dermatology department of our hospital for the management of herpes zoster ophthalmicus. RESULTS: Herpes zoster ophthalmicus was manifested as eyelid eruption (93%), conjunctivitis (80%), keratitis (67%), iridocyclitis (36%), secondary glaucoma (20%), or extraocular muscle palsy (1%). Some patients had accompanying systemic illnesses, including malignancy, hepatitis, diabetes mellitus, chronic obstructive pulmonary disease, tuberculosis, and cerebrovascular disease. Patients with decreased vision during the follow-up period were statistically more likely to have presented with keratitis (p=0.032). However, 86% of these patients recovered vision over a 6-month period. CONCLUSIONS: Patients presenting with keratitis upon initial evaluation are at risk for decreased vision and require appropriate ophthalmic evaluation and management.
