Epstein-Barr viral corneal stromal keratitis occurring during rheumatoid arthritis treatment: a case report

Abstract

Background: A case of Epstein-Barr viral (EBV) corneal stromal keratitis during rheumatoid arthritis (RA) treatment is presented. Case presentation: A 74-year-old female undergoing RA treatment was previously treated for bacterial corneal ulcer and herpetic keratitis and healed with antibiotic eye drops and topical anti-herpes ointment. At the first visit to our hospital, she presented with findings of monocular posterior interstitial keratitis with neovascularization mostly located in the inferior cornea with a corneal epithelial defect. The right eye showed no thinning of the corneal periphery and anterior uveitis. Her RA had subsided with oral steroid treatment, and infectious mononucleosis (IM) had not developed. EBV DNA could be detected in her corneal sample. After an extended but ineffective period to antibiotic treatment the corneal infiltrate responded rapidly to topical corticosteroids. Conclusion: EBV can cause stromal keratitis without IM during treatment for RA.
