Comparison of Intraocular pressure and Body Mass Index in Diabetic and Non -diabetic individuals: A Pilot Study

Journal Name:

Publication Year:

Abstract (2. Language): 
Introduction: Intraocular pressure constitutes the most important risk factor for the emergence of glaucoma which is most often associated with systemic arterial hypertension and diabetes mellitus. Diabetes mellitus is an important ocular risk factor with the occurrence of retinopathy, certain types of lens opacification (cataract), intraocular pressure increase and also, open angle glaucoma during its course .The main objective of this study is to compare the Body Mass Index (BMI ) and Intra Ocular Pressure ( IOP) in normal subjects and subjects with diabetes. Materials & Methods: 74 subjects, aged between 40-70 years, out of which 26 were diabetics and 28 non-diabetics (control group) and also , 20 subjects with both diabetes and hypertension were included in our study after obtaining their consent . Observation: The mean IOP in diabetic group in Right and Left eyes showed an increase in IOP of 0.8 and 1.3 mm Hg when compared with the non-diabetic (control) group. Also, the mean Body Mass Index (BMI) in diabetic group showed 0.8 kg/m2 increase when compared with non diabetic subjects. Results & Conclusion : With this study, we conclude that the mean IOP in diabetic subjects showed a marginal increase when compared with non diabetic subjects . When BMI was evaluated, it was found that the mean BMI in diabetics was 26.4 kg/m2 and the mean BMI was 25.6 kg/m2 in non -diabetics. Body mass index, a measure of obesity, appears to be positively correlated with IOP in diabetic and both diabetic ,hypertensive subjects.
