Purpose: To investigate the incidence, characteristics, risk factors, and treatment outcomes for infectious keratitis in patientswith ocular Sjögren’s syndrome (SS). Methods: We performed a retrospective chart review of patients who had been followed up for ocular SS in Seoul NationalUniversity Hospital from 2010 to 2020 and identified cases where infectious keratitis developed. The incidence, demographicaland clinical characteristics, risk factors, microbiological profiles, and treatment outcome were investigated, some of whichwere compared with infectious keratitis cases in the non-SS group. Results: Out of 929 patients with ocular SS, infectious keratitis occurred in 18 eyes (1.94%). All 18 patients were female in theocular SS group, while 48 out of 100 infectious keratitis patients (48%) were female in the non-SS group (p < 0.01). The meanage at diagnosis of infectious keratitis was 66.1 years in the ocular SS group, which was not different from the non-SS group(57.2 years, p = 0.12). Of risk factors analyzed, the use of therapeutic contact lens was more frequently used in the ocular SSpatients, compared to the non-SS patients (67% vs. 11%, p < 0.01). Culture-positivity rate was 50% in the ocular SS group. Allculture-proven cases were bacterial infection, one of which was bacterial-fungal coinfection. Infection resolved in all eyesafter the mean 29 days of medical treatment, except one that additionally required penetrating keratoplasty with vitrectomy. The visual acuity improved in 15 eyes (83%) after resolution. Infectious keratitis recurred in three patients (17%) during themean 55.7 months of follow-up. Conclusions: The incidence of infectious keratitis was 1.94% in patients with ocular SS. Most were bacterial infections andresolved by medical treatment. Therapeutic and visual outcomes were favorable, but recurrence occurred in 17%.
