A 64-year-old woman was treated for P. aeruginosa keratitis. Twelve days later, she was diagnosed with posterior scleritis and treated with oral ciprofloxacin. Her condition progressed, ultimately resulting in enucleation. Histopathology confirmed posterior scleritis, a previously unreported complication of P. aeruginosa keratitis.
