Evaluation of Anterior Chamber Parameters in Keratoconus Patients with Post-Deep Anterior Lamellar Keratoplasty Glaucoma

Abstract

INTRODUCTION: The purpose of this study was to evaluate iridocorneal angle (ICA) and anterior chamber depth (ACD) that would be associated related to trabecular alteration as a cause of glaucoma following deep anterior lamellar keratoplasty (DALK). METHODS: Ninety-eight eyes of 98 keratoconus (KC) patients were included in this study. We compared pre-operative and post-operative 1st-year values of the ACD and ICA of patients with and without glaucoma following DALK. RESULTS: Four patients (4.1%) had glaucoma following DALK. Pre-operative ACD was 4.24+-0.64 mm and it reduced to 3.41+-0.44 mm post-operatively in glaucoma patients following DALK and; 4.12+-0.56 mm and it reduced to 3.35+-0.53 mm postoperatively in patients without glaucoma following DALK. Pre-operative ICA was 48.65+-7.08 and it reduced to 48.05+-13.14 post-operatively in glaucoma patients following DALK and; 49.48+-7.62 and it reduced to 47.96+-10.32 post-operatively in patients without glaucoma following DALK. DISCUSSION AND CONCLUSION: Our results demonstrate that ACD and ICA values are not significantly different between both groups with or without post-DALK glaucoma in KC patients.
