ASSOCIATION BETWEEN DIABETES MELLITUS AND GLAUCOMA

Abstract

The study's objective was to evaluate the correlation between type 2 diabetes mellitus (T2DM) and primary open-angleglaucoma (POAG).The study was conducted on 180 patients.One hundred elevenwere included in Group A after being diagnosed with T2DM. Sixty-ninesubjects diagnosed with POAG and without T2DM were included in Group B. Examination of the anterior segment, funduscopic evaluation, Optical coherence tomography(OCT) examination,and measurement of Central corneal thickness (CCT) and Intraocular pressure (IOP)weredone. International Society of Geographical and Epidemiological Ophthalmology criteria was used for defining glaucoma. American Diabetes Association criteria werefollowed for defining diabetes.A total of 180 patients were included in the study. The total participants were further divided into threegroups. Group I- subjects with T2DM (80, 44.4%), Group II- subjects with glaucoma and T2DM (30, 16.6%), and Group III- subjects with POAG and without T2DM (70,39%).The study did not confirm the association between glaucoma and T2DM. The mean IOP in Group A and B was 15.76 ± 3.09 mm Hg and 18.36 ±4.38 mm Hg, respectively. The mean CCT in Group A was 539.73±23.7 µm while in Group B was 532.16 ±20.8 µm. The strength of the correlation between glaucoma and T2DM varied with blood sugar level (p<0.001).Thus this study could not confirm the association between glaucoma and Type 2 DM.
