Introduction: Obesity is the one of most worried non communicable diseases. Changing life style, changing food habits, stressful life are risk factors for obesity. Obesity is risk factor for many diseases like hypertension, ischemic heart diseases, stroke and diabetes mellitus. Obesity also increases risk of raised intraocular pressure and glaucoma. Objective: To study correlation between body mass index and intraocular pressure in same age group subjects. Materials and Method: Study included healthy male and female subjects of same age between 45 years to 55 years. Total 150 healthy subjects were included in study and were divided into three groups according the body mass index. Group IBody Mass Index (BMI): 18 to 24.9 Kg/ m2, Group IIBody Mass Index (BMI) 25 to 29.9 Kg/m2and Group IIIBody Mass Index (BMI): 30 and > 30 Kg/m2. Intraocular Pressure (IOP) was measured in right eye and left eye separately using Perkin’s tonometer between 10 am to 11 am to avoid diurnal variations. Statistical Analysis: A nonparametric test, KruskalWallis test, was used to compare groups. In addition, Pearson correlation test was used to find out the correlations between parameters. SPSS 18.0 statistical package was used for statistical analysis. P values of less than 0.05 were considered to be statistically significant. Result: Our study showed statistically significant increase in intraocular pressure with increase in Body Mass Index (BMI) in all three groups. Conclusion: There is significant increase in intraocular pressure with increase in Body Mass Index (BMI) in all three groups. Raised Intraocular Pressure (IOP) is risk factor for glaucoma so obese patient should have regular eye check up and regular trained exercise to avoid complications like glaucoma.
