Corneal crosslinking in Pasteurella multocida–induced severe keratitis

We report the case of a 37-year-old man who presented with redness and swelling in the left eye and visual acuity of light perception after a cat scratch. Slitlamp examination showed a total corneal opacity, inferior stromal thinning, and total corneal erosion. Cultures of the cornea swap revealed Pasteurella multocida , sensitive to the antibiotic regimen. Because of progressive thinning, corneal collagen crosslinking (CXL) was performed to stabilize the cornea. An amniotic membrane was later transplanted because of delayed wound healing. Currently the epithelium is closed and visual acuity is still poor (20/400) due to an extensive corneal scar. The patient is scheduled for keratoplasty. Corneal CXL even without riboflavin was effective in stabilizing the corneal integrity in severe keratitis. Pasteurella multocida can result in severe keratitis with permanent corneal scarring and visual impairment despite adequate therapy.
