PURPOSE: To evaluate the efficacy of intravenous 500 mg methylprednisolone in addition to topical treatment with 1% prednisolone in the treatment of the first episode of corneal endothelial rejection in patients that were submitted to corneal allograft transplantation. METHODS: Retrospective case-control study with 81 patients that presented the first episode of corneal endothelial rejection and were treated within the first 15 days of the onset of symptoms. RESULTS: 67 patients were treated with 1% topical prednisolone acetate and pulsed intravenous methylprednisolone 500 mg at the diagnosis of corneal allograft rejection. Fourteen patients were submitted to topical treatment only, thus forming the control group. Forty-one of 67 patients (61.2%) that were submitted to pulsed steroid had good outcome and 26 (38.8%) presented corneal graft failure while only 4 of 14 patients (28.57%) that received only topical steroids evolved with clear grafts and the remaining 10 patients (71.43%) with graft failure. Chi-square showed statistically significant association (p<0.05) to greater success with pulsed methylprednisolone. CONCLUSIONS: This study suggests that the use of 500 mg intravenous methylprednisolone in addition to 1% topical prednisolone acetate for the treatment of endothelial corneal allograft rejection presents better outcomes in reverting corneal allograft rejection when compared to isolated use of 1% topical prednisolone acetate.
