PURPOSE: Various global indices are available to summarize results from standard automated perimetry. This study asks which index can detect significant deterioration earliest, for a fixed specificity. DESIGN: Comparison of prognostic indices. METHODS: Two cohorts were tested. A test-retest cohort contained 5 reliable visual fields, within a short interval, from 45 eyes of 23 participants with glaucoma and/or likelihood of developing glaucoma. A separate longitudinal cohort contained 508 eyes from 330 participants, tested on average 13 times. Three global indices were extracted; Mean Deviation (MD), Pattern Standard Deviation (PSD) and Visual Field Index (VFI). For each index we defined a critical p-value CritIndex, such that 5% of test-retest series showed significant deterioration with p Devers Eye Institute, Legacy Research Institute, Portland, OR, USA.
