ABSTRACT
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.
