Pseudomonas aeruginosa scleritis.

In two patients Pseudomonas aeruginosa scleral infection led to ocular perforation. In one patient, a scleral abscess was identified anteriorly. A scleral perforation occurred at a more posterior focus, but the eye was salvaged with minimal residual visual function. In the other patient, perforation at the corneoscleral limbus occurred after initial corneal improvement with antibiotic therapy; histopathologic examination of the enucleated globe disclosed an abscess extending from the corneoscleral limbus to the equator superiorly.
