Visual Fields in Normal Korean Measured with Humphrey Field Analyzer

ABSTRACT

Central 30-2 threshold tests were performed in 124 eyes of 62 normal subjects with Humphrey Field Analyzer. The average value of foveal threshold, mean deviation(MD), pattern standard deviation(PSD), shor-term fluctuation(SF) and corrected pattern standard deviation(CPSD) were 34.3+/-2.6dB, -1.96+/-1.31dB, 2.25+/-0.88dB, 1.38+/-0.52dB and 1.41+/-1.10dB, respectively. The frequency of abnormal value on automated perimetry(p<5%) was 25.5% in foveal threshold and 19.1% in MD, which was higher than fundamental data of perimetry. As the age increased, foveal threshold decreased (r=-0.729), PSD and CPSD increased (r=0.422) and 0.385, respectively) ; these are statistically significant correlations(p<0.05). This study has the limitation that test was performed on single session and had small study group. Therefore, further study is needed with comparative analysis following repeated test and larger group of visual field examination.
