To estimate the incidence of scleritis in Lyme disease and report clinical features. Incidence rate estimate and case series. Data were collected from an electronic medical record on patients with scleritis presenting to the Wilmer Eye Institute between January 1, 2012 and December 31, 2020. A diagnosis of Lyme disease was made using the Infectious Diseases Society of America, American Academy of Neurology, and the American College of Rheumatology 2020 joint criteria plus a response to antibiotic therapy. After identifying all new-onset cases of scleritis in the database, the proportion of new-onset scleritis with Lyme disease was calculated. The proportion of Lyme disease cases with scleritis was estimated using the number of cases with Lyme disease from the Baltimore metropolitan area reported to the Centers for Disease Control and Prevention. After querying other major eye centers in the area for any cases of Lyme disease scleritis, none were identified, and the incidence of Lyme disease scleritis was estimated using published U.S. Census data for the greater Baltimore metropolitan area. Six cases of Lyme disease scleritis were identified in the 8-year time frame; 1 additional case was identified in the following year. Lyme disease scleritis accounted for 0.6% of all cases of scleritis, and 0.052% of patients with Lyme disease had scleritis. The estimated incidence of Lyme scleritis was 0.2 per 1,000,000 population per year (95% confidence interval 0-0.4), whereas the estimated incidence of Lyme disease in the area was 3 per 10,000 population per year (95% confidence interval 2.9-3.1). All scleritis cases were anterior, unilateral, without necrosis, and resolved with antibiotic use without relapse in a median of 39.5 days (range 29-57 days). Other features of Lyme disease were present in 4 of 7 patients, including a history of erythema migrans in 2 of 7 patients. Lyme disease is an uncommon cause of scleritis in endemic areas.
