Purpose:To compare two global indices (Mean Deviation, MD, and Pattern Standard Deviation, PSD) and examination time between the SITA Standard (SS) and Full Threshold (FT) strategies in a large sample of visual fields Methods:A group of ocular hypertensives, glaucoma suspects and glaucoma patients prospectively performed FT and SS 24-2 white-on-white testing programs on the same eye during a long term follow up. Results:567 FT visual fields and 498 SS were studied. Mean (± standard deviation) test time for FT and SS showed statistically significant differences between strategies, representing a 52.4 % reduction in examination time for SS compared to FT. Mean deviation (MD) and pattern standard deviation (PSD) for SS and FT showed no significant differences between strategies on this sample of visual fields. Conclusion: SITA Standard yielded a significant reduction in examination time, showing no differences in MD and PSD, when comparing both strategies in a large sample of visual fields of a group of ocular hypertensives, glaucoma suspects and glaucoma patients.
