Objective To analyze the results of White-white standard automatic perimeter(SAP) and flicker perimetery for check in glaucoma patients so as to evaluate the sensitivity of flicker perimetry in glaucoma patients at different stages as well as its diagnostic value. Methods The 46 glaucoma patients(29 males and 17 females,69 eyes) had taken standard automatic perimetery and flicker perimetery(critical fusion frequency,CFF)by using Octopus-900 perimeter(Switzerland Haag-Streit Company). Their average age was 55.41±16.58. According to the MS of SAP,they were again divided into three groups. Group A:less than 10 d B(including 10 d B),Group B:between 10 d B to 20 d B(including 20 d B),and Group C:more than 20 d B;Then compared with the results of SAP and CFF between groups by using fomula 1d B=1.50 Hz. Results In group C mean sensitivity(MS) for CFF was significantly lower than for SAP,but in group A and B on the other hand. Conclusion CFF is more sensitive than SAP in the early stage of glaucoma,but in advanced stage there is no superiority in CFF for diagnosing glaucoma.
