Abstract Purpose:Visual Field Score(VFS), Functional Field Score(FFS), and Functional Vision Score(FVS)were compared with the values measured using the OCTOPUS 900 perimeter(OP)and the Goldmann perimeter(GP). We also measured time and interviewed fatigue level of VFS by OP.

Subject and method:The subjects were 140 patients(male 79, female 61, avg 71.0±11.8 years old)with whom we could obtain informed consent. After measuring the kinetic visual field using the GP Ⅲ/4e, VFS, FFS and FVS were calculated manually using the Colenbrander-Kamo Excel sheet. After measuring VFS by static visual field using Colenbrander grid test(CGT)which is a custom program of OP, FFS and FVS were automatically calculated using Excel macro. In CGT, the false positive and false negative each were less than 33% in the group with good reliability, and those with more than 33% were in the group with poor reliability. Statistical analysis was performed on the correlation between the scores obtained from the results of OP and GP. The FFS class and FVS class were compared. The CGT measurement time and fatigue were also counted.

Results:In the group with good reliability, VFS by OP was 82.5±20.1 and VFS by GP was 86.6±17.4(r=0.77, p<0.001). FFS by OP was 90.1±15.8, and FFS by GP was 91.7±12.6(r=0.73, p<0.001). FVS by OP was 87.9±19.6, and FVS by GP was 89.1±17.1(r=0.88, p<0.001). 75% of the FFS class and 78% of the FVS class of the good reliability group were in the same class in the OP and GP. 63% of FFS class and 75% of FVS class of the poor reliability group were in the same class in OP and GP. In all cases, the CGT measurement time was 230.5±48.9 seconds for one eye, and 81% finished the test without fatigue.

Conclusion:FFS and FVS were almost equivalent in OP and GP. The measurement time of CGT was about 8 minutes on average with both eyes, and most people finished CGT fatigueless.
