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 (¥ÄMD) and the pattern standard deviation (¥ÄPSD) were calculated,
and a correlation between the spherical equivalent (SE) and ¥ÄMD and ¥ÄPSD 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 ¥ÄMD was significant (p=0.02, r=0.62). However, the correlation
between SE and ¥ÄPSD 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¡¾4.26dB and
5.66¡¾3.56dB, 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¡¾3.39dB and 6.62¡¾4.62dB, respectively
(P<0.01).
Conclusion : 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.
