Cross Sectional Study among Intraocular Pressure, Mean Arterial Blood Pressure, and Serum Testosterone according to the Anthropometric Obesity Indices in Korean Men

PURPOSE: To investigate the association between intraocular pressure (IOP) and serum testosterone according to the severity of obesity. MATERIALS AND METHODS: We investigated the correlation of IOP-testosterone according to the anthropometric obesity indices, such as obesity index (OI), body mass index (BMI), and waist circumference to height ratio (WtHR). Each of the obesity indices was classified into three groups: normal, overweight, and obesity. In additional, the association of IOP-testosterone was compared between testosterone 3.0 ng/mL below and above. RESULTS: Total of 3,949 participants, the mean age was 58.86±10.06 years, mean IOP was 14.40±2.61 mmHg, mean arterial blood pressure (MAP) was 93.67±11.47 mmHg, and mean serum testosterone was 4.21±1.83 ng/mL. The association of MAP and IOP was significantly positively correlated according to the severity of obesity, but testosterone showed a significant negative relationship (p<0.05). IOP was significantly correlated with OI and BMI, but MAP and testosterone were correlated with all anthropometric obesity indices (p<0.05). The relationship of IOP and testosterone was significantly associated with only normal groups according to the degree of obesity (p<0.05). The IOP in patients with testosterone above 3.0 ng/mL was significantly higher than testosterone below 3.0 ng/mL (p<0.05). CONCLUSIONS: The correlation of IOP-testosterone has a significantly positive relationship, in case of healthy men with normal weight by OI or BMI.
