PURPOSE: To identify the incidence and risk factors associated with the development of glaucoma after penetrating keratoplasty. METHODS: A retrospective study was carried out in 228 patients who underwent penetrating keratoplasty from January 1995 to January 2000 at the Cornea Section of the Ophthalmology Service at the School of Medicine, Federal University of Uberlândia MG, Brazil. Follow-up time ranged from 4 to 60 months (mean, 17.14 +/- 13.65). RESULTS: Two hundred twenty-eight patients undergoing penetrating keratoplasty were evaluated and 49 (21.5%) developed glaucoma. Risk factors for developing glaucoma were bullous keratopathy [relative risk (RR) = 2.1774), herpesvirus (RR = 1.8979), and trauma (RR = 1.0575). Mean intraocular pressure before transplantation was 15.26 +/- 5.37 mm Hg. Intraocular pressure after transplantation ranged from 22 to 58 mm Hg, with a mean value of 30.04 +/- 7.06 mm Hg. Thirty-six (73.5%) patients had medical treatment, 10 (20.4%) had medical and surgical treatment, and three (6.1%) had surgical treatment. Final intraocular pressure ranged from 4 to 34 mm Hg (mean, 16.79 +/- 5.36). CONCLUSION: The incidence of glaucoma after penetrating keratoplasty is high, and the risk factors include aphakic/pseudophakic bullous keratopathy, herpes simplex virus, and trauma.
