Glaucoma associated with penetrating keratoplasty

Area of Science:

• Ophthalmology
• Corneal Surgery
• Glaucoma Research

Background:

• Penetrating keratoplasty (corneal transplant) is a common procedure.
• Glaucoma is a potential complication following ocular surgeries.
• Understanding risk factors for postoperative glaucoma is crucial for patient management.

Purpose of the Study:

• To determine the incidence of chronic postoperative glaucoma after penetrating keratoplasty.
• To identify risk factors associated with the development of glaucoma post-corneal transplant.
• To evaluate the effectiveness of surgical glaucoma treatments in this patient cohort.

Main Methods:

• Retrospective analysis of 502 penetrating keratoplasty cases in 421 patients (1978-1986).
• Data collection on patient demographics, pre-existing conditions, surgical details, and glaucoma development.
• Statistical analysis to identify significant risk factors for glaucoma.

Main Results:

• The overall incidence of chronic postoperative glaucoma was 18% (91 cases).
• Immediate postoperative glaucoma occurred in 9% and progressive angle closure in 2% of cases.
• Preexisting glaucoma and aphakia were identified as statistically significant risk factors for glaucoma development.

Conclusions:

• Penetrating keratoplasty carries an 18% risk of chronic postoperative glaucoma.
• Aphakia and pre-existing glaucoma are key risk factors.
• Cyclodestructive surgery showed effectiveness, particularly for progressive angle-closure glaucoma.
