应用Tono-pen眼压计测量正常人24h眼压的临床研究

目的研究正常人24 h眼压的变动规律。方法选择年龄为30~60岁的正常志愿者30人(60眼),应用Tono-pen眼压计进行24 h的眼压测量。测量自清晨7:00开始至第二天清晨7:00,每2 h测一次眼压,共测12次。在7:00~23:00时间段中,测受检者的坐位眼压和卧位眼压。在23:00~07:00时间段,测受检者的平卧位眼压。结果志愿者眼压高峰出现在1:30,眼压低谷出现在17:30,24 h坐、卧位眼压变动幅度大于24 h卧位眼压变动幅度。结论正常人的眼压高峰大多出现在夜间睡眠时间,测受检者的坐、卧位眼压是一种较好的24 h眼压测量方法。

Clinical study of the twenty-four-hour pattern of intraocular pressure in normal people using a Tono-pen tonometer

Objective To characterize the twenty-four-hour pattern of IOP in normal people.Methods Thirty healthy volunteers from 30 to 60 years old were selected for the study.IOP was measured with a Tono-pen tonometer over 24 hours.Measurements of each eye were taken every 2 hours(12 times in 24 hours).Both the sitting IOP and supine IOP were measured between 7:00 and 23:00(once every 2 hours).Results The lowest IOP occurred at 17:30 and the peak IOP occurred at 1:30.The value between trough and peak in the twenty-four-hour pattern of sitting and supine IOP was higher for the supine IOP.Conclusion The peak IOP in most normal people occurred at night while asleep.The measurement of sitting IOP at 7:30,11:30,17:30 and 21:30 and supine IOP at 23:30 and 5:30 is a new effective method to evaluate the twenty-four-hour pattern of IOP.
