目的:本研究旨在比较在家中及在医院监测24h眼压波动的情况。方法:前瞻性调查研究。本研究共纳入成都地区五个社区共计120名中国籍居民作为研究对象。所有人均接受了临床调查并在家中及医院进行眼压监测,用同一型号眼压计测量了2点、6点、8点、10点、12点、14点、16点、18点、20点、22点的坐位眼压。结果:在医院监测的24h眼压平均值略低于在家中测量值,平均差为0.27 mmHg,两者比较差异无统计学意义。在医院监测的24h眼压的波动值略高于在家中测量的波动值,平均差为0.01 mmHg。14点在家中测量的眼压平均值(16.04±5.95 mmHg)显著高于在医院测量的眼压平均值(15.43±5.16 mmHg),差异有统计学意义(P<0.05)。在家中及在医院24h眼压监测对于临床上原发性开角型青光眼诊断的一致性为85%(K系数:0.68)。结论:在医院进行的24h眼压监测的结果与在家中的结果相似。医院24h眼压监测可用于原发性开角型青光眼的诊断。
Objectives: This study was designed to compare the changes of intraocular pressure (IOP) fluctuations monitored at home and in the hospital for 24h. Methods: Prospective investigation. In this study, a total of 120 Chinese residents in five communities in Chengdu were included as research subjects. All received clinical investigations and monitored intraocular pressure at home and in the hospital. Twenty-one, six, eight, 10, 12, 14, 16, 18, 20 , 22-point sitting pressure. Results: The mean IOP of 24h monitored in the hospital was slightly lower than that measured at home, with an average difference of 0.27 mmHg. There was no significant difference between the two. The intraocular pressure fluctuations monitored at the hospital for 24 h were slightly higher than those measured at home with an average difference of 0.01 mmHg. The mean intraocular pressure measured at 14 o’clock at home was significantly higher (16.04 ± 5.95 mmHg) than that measured at the hospital (15.43 ± 5.16 mmHg), with a statistically significant difference (P <0.05). Intraocular pressure monitoring at home and in hospital at 24 h was 85% consistent with the clinical diagnosis of primary open-angle glaucoma (K-coefficient: 0.68). Conclusions: The results of intraocular pressure monitoring at the hospital at 24 hours were similar to those at home. Intraocular pressure monitoring 24h can be used for the diagnosis of primary open-angle glaucoma.
