目的 观察和分析配戴角膜塑形镜后非接触眼压(NCT)的变化.方法 回顾性病例对照研究.对配戴角膜塑形镜的303例青少年近视患者,按照屈光度分为低、中、高度近视组.分别在戴镜前、戴镜后1d、1周、1个月及3个月时测量NCT、角膜曲率以及进行主、客观验光.对相关数据进行连续测量的单因素方差分析,两两比较采用LSD检验.结果 配戴角膜塑形镜1周后NCT趋于稳定,并且较戴镜前降低(F=51.75,P＜0.01),但在戴镜后1d,中高度近视眼压分别较戴镜前升高1.04 mmHg(t=-4.81,P＜0.01)及0.58 mmHg(t=-2.65,P＜0.05),低度近视眼压则呈下降趋势(t=0.57,P＞0.05).戴镜后3个月,屈光度改变量与眼压改变量呈正相关(r=-0.131,P＜0.05),不同程度近视每单位屈光度所致眼压改变不同(F=3.57,P＜0.05).其中,低度近视每单位屈光度改变导致眼压下降0.50 mmHg,高于中度近视(t=-2.57,P＜0.01),而低度与高度近视(t=-1.86,P＞0.05)、中度与高度近视(t=0.68,P＞0.05)之间则无明显差异.结论 配戴角膜塑形镜后NCT下降,眼压值的下降应该与角膜形态因素以及眼调节功能等因素有关.

Objective To evaluate the changes of intraocular pressure (IOP) in myopic children undergoing overnight orthokeratology treatment.Methods It was a retrospective case-series study.Orthokeratology was performed to correct the refractive errors of 303 eyes of 303 teenagers.The patients were divided into 3 groups:low-myopia,moderate-myopia,and high-myopia,based on the diopters.IOP,corneal curvature and refraction were taken respectively at pre-wear,1 day and 7,30,90 days after orthokeratology.Data were analyzed by repeated-measures ANOVA tests.LSD corrections were performed to compare the differences in I0P if significant differences were found.Results The change of IOP became stable after 1-week orthokeratology treatment,and were significant decrease in IOP after treatment (F=51.75,P＜0.01).Moderate and high myopia had an increase of 1.04 mmHg (t=-4.81,P＜0.01) and 0.58 mmHg (t=-2.65,P＜0.05) respectively in IOP at 1-day visit,and low myopia only showed a downward trend at the same time (t=0.57,P＞0.05).Furthermore,the changes in diopters were positively correlated with those in IOP (r=0.131,P＜0.05)3 months post-treatment.The changes of IOP resulted by one unit change in diopter were significantly different among different degree of myopic group (F=3.57,P＜0.05).With one unit change in diopter,the low-myopia teenagers showed significantly more reduction in IOP at 0.50 mmHg than moderate-myopia teenagers (t=-2.57,P＜0.01).No significant differences were observed between low-and high-myopia groups (t=-1.86,P＞0.05),moderate-and high-myopia groups (t=0.68,P＞0.05).Conclusion Orthokeratology results a decrease in IOP measurements.The observed patterns of IOP changes may be caused cooperatively by the changes in corneal morphology and eye accommodation function.
