Aim: To determine association between central corneal thickness and type 2 diabetes mellitus in patients attending outpatient department of Ophthalmology at a tertiary care centre in North Karnataka. Materials and Methods: This is a cross-sectional study conducted over a period of April 2018 – September 2020 on patients attending outpatient department of Ophthalmology at a tertiary care centre in North Karnataka. Study includes 168 subjects divided into 3 groups: 40 diabetics whose duration >10 years46 diabetics whose duration ?10 yearsand 82 controls.Detailed ophthalmic examination was conducted in all patients and central corneal thickness was measured using ultrasound pachymetry. Results: A statistically significant difference was found between mean central corneal thickness of diabetics (534.0581µ - right eye; 534.3605µ - left eye) and non-diabetics (525.8659µ - right eye; 525.8659µ - left eye); p value Conclusion: Patients with type 2 diabetes mellitus have thicker corneas as compared to non-diabetics. Henceforth, it is important to measure central corneal thickness in all diabetics, as it affects IOP measurement which is vital for early diagnosis and timely treatment of glaucoma. Keywords: CCT, T2DM, Ultrasonic pachymetry.
