原发性开角型青光眼患者及正常人的眼压日内波动趋势

目的研究原发性开角型青光眼（POAG）、正常眼压性青光眼（NTG）患者及正常人双眼眼压昼夜波动趋势及其眼压峰值出现的规律，比较双眼眼压波动趋势是否一致。设计前瞻性病例系列。研究对象POAG、NTG患者及正常对照各30例。方法用Goldmann压平眼压计测量眼压日曲线，比较双眼的日眼压波动模式及眼压峰值分布。主要指标眼压测量值。结果眼压峰值出现于非办公时段的正常人为右眼6．7％、左眼10．0％；NTG患者为右眼20．0％、左眼23．3％；POAG患者为右眼23．3％、左眼20.0％。结论POAG、NTG患者和正常人有着不同的眼压昼夜波动模式，且双眼的波动趋势不尽相同，不能完全将双眼等同看待；部分观察对象的峰值眼压分布于非办公时段，办公时段多次眼压测量不能完全代替一日眼压监测。（眼科，2007,16：33．36）

Study of intraocular pressure diurnal variation curves in patients with open-angle glaucoma and normal subjects

Objective To observe the diurnal variation of intraocular pressure(IOP)measured with Goldmann applanation tonomoter(GAT)in patients with primary open angle glaucoma(POAG),normal tension glaucoma(NTG)and healthy controls,and to compare the differences of diurnal variation curves between two eyes of each subject and define the distribution of the peak of IOP. Design Prospective case series.Participants POAG patients,NTG patients and healthy controls.Methods The diurnal variation of IOP in the two eyes of each of 30 POAG patients,30 NTG patients and 30 normal controls were investigated and the distributions of the peak IOP were observed.Main Outcome Measure Intraocular pressure.Results Measured with GAT,6.7% right eyes and 10.0% left eyes of normal people,20.0% right eyes and 23.3% left eyes of NTG patients,and 23.3% right eyes and 20.0% left eyes of POAG patients showed peak IOP at the time points of out-office period.Conclusions POAG patients,NTG patients and normal controls have asymmetric IOP diurnal variation.The two eyes of one individual cannot always be treated as the same.The IOP peak can occur at the time point during the out-office time.Measure IOP in office-time only may miss the dynamic information of IOP.
