    Abstract:
    PURPOSE: To compare visual field results obtained using Melbourne Rapid Fields (MRF) iPad-based perimeter software and Humphrey Field Analyzer (HFA) 24-2 Swedish Interactive Threshold Algorithm (SITA) standard program in glaucoma patients. DESIGN: A cross-sectional observational study. METHODS: In this single-centre study involving patients diagnosed with glaucoma, the perimetric outcomes of MRF were compared against those returned from the HFA 24-2 SITA standard. Outcomes included mean deviation (MD), pattern standard deviation (PSD), visual field index (VFI)/visual capacity (VC), foveal threshold, test time, number of points depressed at P < 5% on PSD probability plot, and glaucoma hemifield test/color coded indicator. RESULTS: The study included 28 eyes of 28 glaucoma patients. Mean (standard deviation) test times were 342.07 (56.70) seconds for MRF and 375.11 (88.95) for HFA 24-2 SITA standard (P=0.046). Mean MD was significantly lower for MRF (Δ = 3.09, P < 0.001), and mean PSD was significantly higher for MRF (Δ = 1.40, P=0.005) compared with HFA. The mean foveal threshold for the MRF was significantly lower than the mean HFA foveal threshold ((Δ = 9.25, P < 0.001). The number of points depressed at P < 5% on the PSD probability plot was significantly less for MRF (P < 0.001). Other perimetric outcomes showed no significant differences between both. Bland-Altman plots showed that considerable variability existed between the programs. CONCLUSION: MRF is a good cost-effective, time-saving, user-friendly tool for monitoring visual fields in settings where access to traditional perimetry is limited. The lack of Internet strength in rural areas and questionable detection of early cases may be two points in MRF fields requiring an upgrade.
