Abstract Details

Purpose:

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)

Setting:

Retrospeictive observational study

Methods:

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).

Results:

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).

Conclusions:

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.
