Pseudomonas corneoscleritis.

We evaluated three cases of Pseudomonas aeruginosa corneoscleritis, one associated with the use of contaminated eyedrops; another in an elderly, debilitated patient; and the third in a patient who had previously undergone penetrating keratoplasty. In the first two cases, control of the infection was achieved by intensive antibiotic therapy alone. The third case required evisceration of the eye following spontaneous perforation at the site of scleral involvement. Histopathologic findings showed persistence of the organism in the sclera despite intensive antibiotic therapy for six days.
