Analysis of visual field series in order to detect and measure progression may be performed either by event analysis or trend analysis. Event analysis constructs a baseline and compares subsequent tests to the baseline. Trend analysis models the behaviour of the whole series, for example by linear regression.This talk will give examples of how each technique has been used in clinical research and will also present evidence from studies comparing the two.
