Objective: Determination of whether or not the central corneal thickness (CCT) is different in patients with type 2 diabetes mellitus (DM) than the normal individuals.
Material and Methods: Patients with type 2 DM followed up in retina department of our clinic were investigated. Records of 78 patients done their measurements of CCT were evaluated retrospectively. Preoperative CCT records of 47 cataract patients were taken as a control group with purpose of comparing with CCT results of patients with type 2 DM. The diabetics were divided into 2 groups as having diabetic retinopathy (Group 2, 32 patients) and not (Group 1, 46 patients), and the 47 control cases were classified as Group 3. CCT was measured via ultrasonic pachymeter under topical anesthesia.
Results: The mean CCT was found as 556.17 ± 36.53 μm in Group 1, 553.34 ± 37.63 μm in Group 2, and 534.77 ± 42.26 μm in Group 3, and it was significantly greater in Group 1 and 2 against the Group 3 (P= 0.011 and 0.049, respectively). On the other hand, the difference between the Group 1 and 2 was not significant (P= 0.740). When we compared the CCT according to gender distribution, the difference was not significant in all of the three groups. Additionally, when we performed a linear regression analysis in the 78 diabetic patients, there was not a significant correlation between the duration of DM and CCT (P= 0.794).
Conclusion: CCT is significantly greater in diabetics than the control group being independent from the duration of DM. Thus, attention is required during the diagnosis of glaucoma in patients with DM.Keywords: Diabetes mellitus; glaucomaTurkiye Klinikleri J Ophthalmol 2007, 16:73-76
