目的：评价24h眼压测量在青光眼患者诊断中的意义。
方法：选择青光眼疑似患者51例51眼，使用Goldmann眼压计进行24h眼压测量。
结果：所有患者中，21眼(41.2%)的眼压在正常范围内且昼夜眼压波动小于6mmHg(1mmHg=0.133kPa)，30眼(58.8%)出现昼夜眼压波动过大或峰值眼压高于21mmHg。其中7例出现仅有夜间高眼压且最高者达54mmHg，白天自然缓解到正常范围。24h眼压平均值及高峰值与门诊眼压记录相比，差异均具有统计学意义(P<0.01)。
结论：24h眼压测量与门诊检查眼压相比，能更好地发现高眼压和昼夜眼压波动异常患者。

AIM: To determine the value of 24-hour intraocular pressure(IOP)monitoring in routine clinical practice of suspects of glaucoma.
METHODS:Fifty-one suspects of glaucoma(51 eyes)were selected for 24-hour IOP monitoring without any anti-glaucoma therapy. Goldmann tonometer was used for 24-hour IOP measurement.
RESULTS: In all of 51 eyes, there were only 21(41.2%)eyes with IOP kept in normal range and IOP variation amplitude under 6mmHg, 30 eyes(58.8%)were with large diurnal fluctuations in IOP or the peak IOP up to 21mmHg. The IOP of the 7 eyes were with intraocular hypertension only at night, with highest IOP of 54mmHg, with daytime IOP relieved to normal range. The 24-hour IOP monitoring were higher than of the daytime IOP measurement(P<0.01).
CONCLUSION:Compared with the daytime IOP measurement, the 24-hour IOP monitoring could identify diurnal IOP and/or IOP spikes better.
