Abstract:【Objective】 To analyze the distribution of intraocular pressure (IOP) of emmetropia people in physical examination and related factors so as to understand the relationship between IOP and common medical systemic diseases. 【Methods】 The IOP of emmetropia people in physical examination in our hospital was summarized. The correlations between IOP and age, gender, blood pressure, glycosylated-hemoglobin, blood lipids, glutamyl transaminase and health education were analyzed by multiple linear regression analysis. 【Results】 The mean IOP of the right eye was (15.53 ± 2.71) mmHg, that of the left eye was (15.66 ± 2.73) mm Hg. The right eye and the left eye IOP had no statistical difference (t = -1.179, P > 0.05). Then the left eye was chosen for further analysis. The age (β = -0.038, P < 0.001), gender (β = -0.498, P < 0.05), systolic blood pressure (β = 0.029, P < 0.001), dyslipidemia (β = 0.603, P < 0.05), glutamyl transaminase (β = 0.003, P < 0.01) and health education (β = 0.176, P < 0.05) were independently associated with intraocular pressure. 【Conclusion】 Mean IOP in emmetropia people is 15.66 mmHg, and is associated with the systolic blood pressure, dyslipidemia, health education and glutamyl transaminase.
