PURPOSE: To describe clinical features and presentation of infectious scleritis resulting from herpes viruses. DESIGN: Retrospective case series. PARTICIPANTS: Thirty-five patients out of 500 with scleritis. METHODS: We reviewed the electronic health records of 500 patients with scleritis, 35 of whom were diagnosed with herpes virus infection, seen at 2 tertiary referral centers. We studied the clinical features and ocular complications of this subset of patient with scleritis. MAIN OUTCOME MEASURES: Correlation between classification, severity, and symptoms (i.e., pain) and diagnosis of herpetic-associated scleritis. Vision loss, presence of associated uveitis, keratitis, glaucoma, or systemic disease were documented over the follow-up period. Other outcome measures included epidemiologic data: age, gender, laterality, visual acuity, duration of symptoms, and underlying systemic or ocular diseases. RESULTS: Of 500 patients with scleritis, 47 (9.4%) had an underlying infectious cause. Thirty-five (74.4%) of these were diagnosed with herpes virus infection, 5 (10.6%) with tuberculosis, and the remaining 7 (14.8%) with other infectious disease. Patients with herpes-associated scleritis were analyzed as a group and then compared with those with idiopathic scleritis. Most patients with herpetic scleritis presented with acute (85.7%) and unilateral (80%) scleral inflammation. Pain was moderate or severe in 68.6% of the patients. The most common type of scleritis was diffuse anterior in 80% (n = 28), followed by nodular anterior 11.4% (n = 4), and necrotizing in 8.6% (n = 3). Necrotizing anterior scleritis was more commonly seen in patients with herpetic scleritis versus patients with idiopathic disease (8.6% vs 1.2%; P<0.05). Unilaterality was also more common in herpetic scleritis (80%) than in idiopathic disease (56.7%; P<0.05). Vision loss was significantly greater in herpetic than idiopathic scleritis (34.3% vs 11.5%; P<0.001). CONCLUSIONS: The association between scleritis and infectious disease may be higher than previously reported by other series. Herpes viruses account for 7% of all scleritis cases and its diagnosis may be challenging when there is not a classically diagnostic clinical picture. We present the observed clinical features of herpetic scleritis and describe the clinical differences at presentation between patients with idiopathic scleritis and those with herpes infection.
