The Effect of Myopic Optical Defocus on the Humphrey Matrix 30-2 Test

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
