Abstract

Background and Aim: Diabetes has emerged as an important global health concern because of its various adverse effects on the ocular tissue. The present study was done to study the correlation between type 2 diabetes mellitus and central corneal thickness in patients coming to the tertiary care institute of Gujarat, India.

Material and Methods: The present study was conducted over 1 year at the tertiary care institute of Gujarat, India.50 patients with type 2 diabetes mellitus previously diagnosed by a physician on treatment and 50 age-matched controls who are non-diabetics on history and blood sugar levels were enrolled. The central corneal thickness was measured using an ultrasound pachymeter using multiple reading single point modes by a single person.

Results: The mean central corneal thickness in diabetics was 565 ± 21 micrometres and in non-diabetics was 517 ± 20 micrometres. The central corneal thickness was found to be higher in patients with type 2 diabetes mellitus when compared to non-diabetics.

Conclusion: Patients with type 2 diabetes mellitus were found to have thicker corneas as compared to non-diabetics. This should take into consideration while interpreting intraocular pressure and before any refractive surgeries in diabetics.
