Glaucoma in keratoplasty.

This paper reports intraocular pressure findings in 676 eyes that received penetrating keratoplasties. There were four groups: 1. keratoconus without preoperative glaucoma (75 cases); 2. Fuchs' dystrophy and cataract (triple procedure) without glaucoma (260 cases); 3. aphakic eyes with or without intraocular lenses (204 cases); and 4. pseudophakic eyes with or without intraocular lens removal (137 cases). The last two groups had a significant number of glaucoma cases. All were controlled before surgery. There were no early or late glaucoma cases in the first group. A few cases with triple procedures had mild early intraocular pressure elevation. Thirty percent of aphakic eyes and 52% of pseudophakic eyes had early glaucoma. Twenty percent and 25% of these two groups had persistent glaucoma. Preoperative glaucoma eyes were included in these long-standing glaucoma cases.
