Study of impact of diabetes mellitus on anterior chamber depth as detected by partial coherence laser interferometry

Abstract

Aim: A n observational cross-sectional study conducted to analyze the impact of diabetes mellitus on anterior chamber depth. Materials and methods: 100 Consecutive diabetic patients aged 40 years and above who attended the Department of Ophthalmology of Command Hospital (Air force) fulfilling the eligibility criteria were included after obtaining informed consent. Anterior chamber depth (ACD) was measured using I O L Master (partial coherence laser interferometry). Patients were grouped into different categories based on duration of diabetes and the glycemic control. Results: 100 right eyes of as many patients were studied. The mean ACD of patients with diabetes more than 5 years was 2.59+0.42 mm compared to 2.74+0.33 mm of patients with less than 5 years duration was statistically significant (p=0.056). In patients with controlled diabetes the mean ACD was 2.96+0.21 mm as against 2.50+0.32 mm of patients with poorly controlled diabetes which was statistically significant (p<0.0001). Conclusion: This study showed that diabetic patients with more than 5 years duration and poor glycaemic control had shallower anterior chamber, than that of those who had diabetes less than 5 years duration and good glycaemic control. ACD can be used as a screening tool for detecting angle closure disease in diabetic patients.
