Central corneal thickness, anterior chamber depth, and axial length in patients with type II diabetes mellitus

Abstract

Purpose: The aim of this study was to study the central corneal thickness (CCT), anterior chamber depth (ACD), and axial length (AL) in patients with type II diabetes mellitus and compare it with healthy controls. Methods: A hospital-based nonrandomized prospective comparative study was conducted on 50 type II diabetics and 50 healthy controls. Complete ophthalmic examination was performed. CCT was measured using an ultrasound pachymeter, ACD, and AL was measured using an optical biometer. Statistical comparisons were done between the cases and controls. Results: The mean CCT in diabetic group was significantly higher (531.00 ± 33.42 μm) compared to control group (505.70 ± 32.19 μm) (P 0.05). AL s were comparable between the two groups. Conclusion: Patients with type 2 diabetes mellitus in our study had a thicker CCT and shallow anterior chamber regardless of retinopathy status, duration of diabetes mellitus, glycemic control.
