To evaluate the corneal complications associated with the combined use of nonsteroid anti-inflammatory drugs (NSAIDs) and topical steroids following vitreoretinal surgery.
METHOD.
Description of corneal lesions in three patients after vitrectomy with use of topical ketorolac and prednisolone acetate.
Results
Three eyes of three patients developed an atrophic central corneal ulcer with stromal thinning following a pars plana vitrectomy under local anesthesia. Lesions were asymptomatic and were found during a routine examination 2, 3, and 8 weeks after surgery, respectively. Surgical indications were as follows: a pre-retinal membrane, choroidal neovascularization, and massive uveal effusion following cataract surgery. Topical postoperative treatment was as follows: ketorolac 4 times a day, a combination of prednisolone acetate, polymyxin B, and neomycin 6 times a day, and 1% cyclopentolate 3 times a day. Suspension of ketorolac and ocular occlusion led to the resolution of corneal lesions between 2.5 and 3 months later, yielding a central superficial scarring, which showed no changes after a follow-up of 3 years.
Conclusions
Toxic keratolysis may appear as a secondary effect of the combined use of topical NSAIDs and steroids following vitreoretinal surgery and must be taken into account in the differential diagnosis of postoperative corneal lesions.
