CORRELATION BETWEEN CENTRAL CORNEAL THICKNESS IN DIABETICS AND NON DIABETICS WHEN MEASURED WITH SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY

Dr Shobha G Pai, Dr Vasuraj

Abstract :

Purpose: To compare the central corneal thickness(CCT) of diabetics with age and sex matched non–diabetic controls using SD–OCT and to study the correlation of CCT with HbA1c , duration of disease. Methods: Crosssectional observational study conducted on 50 diabetics and 50 nondiabetics age and sex matched. Results:CCT values of diabetics and non diabetics were noted to be different, statistically different(p value<.001) and CCT was found to be correlated with poor glycaemic control and duration of disease.Conclusion:CCT of diabetic patients is thicker , suggests endothelial dysfunction. Increase in CCT is considered to be one of the earliest clinically detectable changes of the diabetic eye. Diabetics with HbA1c >7% had thicker corneas than patients with < 7%. CCT was found to be thicker in diabetics >10 years duration.
