探讨24h眼压检查对青光眼诊断的意义

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。

Analysis on the value of 24-hour IOP monitoring in diagnosis of suspects of glaucoma

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.
