Abstract Details


To investigate clinical utility of central 24-2 threshold test compared with 30-2 threshold test using Humphrey visual field (Carl Zeiss Meditec, Dublin, CA, USA)


Retrospeictive observational study


Glaucoma and glaucoma suspect patients who underwent both central 30-2 and 24-2 threshold test using SITA-standard method from November 2010 to January 2016 were recruited. We compare test time, fixation loss(%), false positive errors(%), false negative errors(%) which are an index of reliability. Also we compared mean deviation(MD), pattern standard deviation(PSD), visual field index(VFI).


The 366 eyes of 183 patients were included in this study. Their mean age was 54.67±14.95. MD, VFI, and fixation loss showed no significant difference between central 30-2 and 24-2 threshold test. However, 24-2 threshold test provided shorter time from 7.52±1.39minutes to 5.65±1.10minutes(p<0.001). Their difference was approximately 24.51±9.44%. False positive errors was significantly increased from 3.41±4.15% to 4.06±5.22%(p=0.009), but false negative errors was decreased from 4.70±5.36% to 3.55±5.05%(p<0.001). PSD was decreased from 4.76±3.65dB to 3.95±3.44dB(p<0.001).


Compared with 30-2 threshold test, since 24-2 threshold test can reduce test time about 24.51% without change of reliability, it can be more efficient examination for the patients.
