Abstract

PURPOSE
To investigate the effect of lens-corrected myopia on Humphrey Matrix and Humphrey Field Analyser (HFA). METHODS: A total of 59 lens-corrected myopic eyes of 59 normal volunteers underwent Humphrey Field Analyser and Humphrey Matrix (FDP) testing. Spherical equivalent divided into 3 groups: -3 < or = D < 0, -6 < or = D < -3, D < -6. HFA and FDP sensitivity for mean deviation (MD) and pattern standard deviation (PSD), as well as axial length and astigmatism, were compared between these 3 groups. RESULTS: The MD of the fields as determined by the HFA decreased significantly as the refractive errors increased, despite correction. However, there were no significant differences in MD or PSD of FDP, or in the PSD of HFA. There were no significant differences in axial length or astigmatism as calculated by MD and PSD for HFA and FDP. CONCLUSIONS: The spherical equivalent showed that lens correction alters the MD for HFA but not for FDP.
