Peripheral ulcerative keratitis (PUK) is a destructive, inflammatory process that can lead to corneal perforation and visual loss. Successful control of PUK has been reported with conjunctival resection, cyanoacrylate adhesive, and systemic immunosuppression. Cases with impending or actual corneal perforation may require more extensive surgery, including lamellar or penetrating keratoplasty, to maintain the integrity of the globe. We report on 17 eyes of 14 patients with PUK that required tectonic keratoplasty because of progressive ulceration. Surgery with concomitant immunosuppression preserved the eyes in all but two cases, and 8 of 17 eyes maintained or improved preoperative visual acuity. Six eyes had final visual acuities of 20/200 or better. This therapeutic strategy can preserve eyes that might otherwise be lost to progressive inflammation.
