근시가 험프리 매트릭스 30-2 검사에 미치는 영향 = The Effect of Myopic Optical Defocus on the Humphrey Matrix 30-2 Test

다국어 초록 (Multilingual Abstract)

`Purpose: To investigate the effect of myopic optical defocus on Humphrey Matrix 30-2 test. Methods: Twenty-nine myopic eyes of 29 patients underwent 2 consecutive tests with the Humphrey Matrix 30-2 threshold program. The first and second tests were performed with and without correction for myopia. Differences between the mean deviation (?MD) and the pattern standard deviation (?PSD) were calculated, and a correlation between the spherical equivalent (SE) and ?MD and ?PSD was investigated. The influence of optical defocus according to the visual field (central and peripheral) and the severity of glaucomatous visual field damage (area with total deviation plot of ‘P<0.1%’ or ‘P<0.5%’ and the other area) were also evaluated. Results: The correlation between SE and ?MD was significant (p=0.02, r=0.62). However, the correlation between SE and ?PSD was not significant (p=0.81, r=0.15). The differences in the mean total deviation printout value of the central and peripheral visual field groups between the two tests were 5.85±4.26dB and 5.66±3.56dB, respectively (P=0.86). The differences in the mean total deviation printout value of severely damaged and less damaged areas between the two tests were 3.16±3.39dB and 6.62±4.62dB, respectively (P<0.01). Conclusions: Myopic optical defocus has a significant effect on the results of the Humphrey Matrix 30-2 test. There is no difference in the effect of myopia between the central and peripheral visual fields, and the effect is decreased in severely damaged visual fields.`
