Intraocular pressure and its correlated factors in Uygurs students in primary and secondary schools

Abstract

Objective To discuss the correlations between intraocular pressure (IOP) and gender, age, central corneal thickness (CCT), diopter, in Uyghurs students in primary and secondary schools. Methods This study used stratified cluster random sampling. Random 326 cases of complete information (652) of Uyghur primary and secondary students based on 2011 Karamay primary myopia in different ethnic groups in the epidemiological survey for statistical analysis. Results The median of IOP was 17.0mmHg, The mean of CCT was (545.17±34.87)µm. There was no significant difference between boys and girls on IOP (z=-1.651, P=0.099). There was statistically significance during the IOP, central corneal thickness between different ages (χ2=29.517, P=0.000; F=5.625, P=0.000), There was statistically significance between Different refractive states (χ2=8.057, P=0.018). Using Spearman correlation analysis, IOP was correlated with age (r=0.202, P=0.000), IOP was correlated with CCT (r=0.453, P=0.000), CCT was correlated with age (r=0.139, P=0.000). Conclusions There is direct linear correlation between IOP and CCT, also IOP is correlated with age in Uyghur primary and secondary students. Analysis of the changes of intraocular pressure in primary and middle school students with the above factors in clinical work, and through the understanding of the changes of the intraocular pressure indicate the change of the refractive state of the eye. At the same time, the treatment and prevention of myopia and ocular hypertension are helpful.
