Intraocular pressure is fluid pressure inside the eye. Elevated IOP is an important risk factor in obesity. Obesity does not only risk factor of elevated intraocular pressure, but also increase risk in elevated blood pressure. An increase body mass index also significantly associated with increase blood pressure. This study investigate the correlation between body mass index, blood pressure and intraocular pressure in obesity. A prospective, analytical observational with cross sectional design was conducted at Sumatera Utara Universitas Hospital from July 2017 to August 2017 after approved by Ethics Committee for Health Research Medical Faculty Universitas Sumatera Utara. Fifty six patients diagnosed with obesity were evaluated. Obesity was measured by using Body Mass Index, while Body Mass Index calculated as body weight (kg) divided by heigh (m) squared, Blood Pressure was measured by GEA mercurial sphymometer and Litmann Sthetoscope and Intraocular Pressure was measured by Non-contact tonometer TOPCON CT-80A (Tokyo,Japan). There was a significant correlated between intraocular pressure with obesity (p<0,05) and significant correlated between intraocular pressure and blood pressure (p<0,05). Elevated intraocular pressure and blood pressure is a risk factor in obesity
