Abstract:
Automated static perimeters, which are commonly used for early diagnosis and follow-up of glaucoma patients in Korea, are manufactured overseas, and their basic data were obtained from foreigners and normal values were set to meet them. Therefore, verification of validity of those data should precede their application to Koreans. We compared the mean normal values of standard indices of OCTOPUS 101 automated static perimeter with the values obtained from 140 eyes of 70 healthy Koreans using normal strategy(NS)and dynamic strategy(DS). Mean navlues of mean defect(MD), loss variance(LV), corrected loss variance(CLV), and short-term fluctuation(SF)were: 2.84+/-0.85dB, 2.15+/-0.54dB, 1.22+/-0.42dB, 1.43+/-0.22dBwith NS, and 2.05+/-0.81dB, 1.98 +/-0.58dB, 0.97+/-0.49dB, 1.43+/-0.24dB, repectively with DS. With NS, 114 of 140 eyes (81. 4%)were out of the normal range of MD. With DS, 67 of 140 eyes(47. 9%)were out of normal range of MD, and 2 of 140 eyes(1. 4%)were out of the normal range of SF. Values of the other indices were within normal range of both strategies. Statistical analysis of global indices showed that age was significantly correlated with LV, CLV and SF in NS(P<0.05), and that it was also correlated with LV and CLV in DS(P<0.05). These results suggest that both race and age should be taken into acoount in interpretation of visual fields on automated static perimetry.
