Abstract:
We compared the full threshold method, central 30-2 Humphrey perimetry with a newer strategy of SITA-standard.To valuate the clinical usefulness, 30 glaucoma patients and 20 normal persons underwent both tests. MD, PSD and test time were comparatively analyzed.In glaucoma patients, the mean test time was 7 min 37 sec[+/-1 min 54sec]for the SITA-standard, while it was 14 min 55 sec[+/-1 min 58 sec]for the full threshold method.The mean value of MD were -7.62 +/-7.93 and 8.85 +/-8.19, while PSD were 5.89 +/-4.24 and 6.50 +/-4.07, repectively. In normal persons group, the mean test time was 6 min 56 sec[+/-1 min 3sec]for the SITA-standard, while it was 14 min 1 sec[+/-1 min 24 sec]for full threshold method.The mean values of the MD were -2.41 +/-0.87 and 3.00 +/-1.31, while the mean values of the PSD were 2.04 +/-0.47, 2.12 +/-0.50, respectively. In conclusion, the SITA-standard did not show any significant differences in both MD and PSD.However, the test time was reduced 49%in glaucoma patients and 53%in normal persons.Therefore, the SITA-standard exhibited similar clinical significance on both glaucoma patient and glaucoma suspect.So it was an useful and effective test to reduce test time.
