[Purulent scleritis following penetrating keratoplasty for acanthamoeba keratitis].

The problem of treating purulent scleral infections, rare but extremely severe complication of ophthalmic surgeries, remains unresolved. This article presents a case of successful surgical treatment of purulent scleritis - interlamellar scleral abscess - that developed in a patient after repeat penetrating keratoplasty performed due to infectious lysis of the transplant. Although the first keratoplasty was performed for acanthamoeba keratitis, there were no signs of acanthamoeba invasion in the transplant at the time of the second surgery. Scleritis manifested as an infiltrate with pus penetrating the anterior chamber and development of keratoiridocyclitis. During surgery, the abscess cavity was opened, irrigated with an antiseptic solution, and drained into the subconjunctival space; the anterior chamber was irrigated with balanced salt solution through a separate paracentesis. No infection recurrences were noted in the postoperative period and the corneal transplant remained clear.
