Visual field index rate and event-based glaucoma progression analysis: comparison in a glaucoma population

Abstract

Event-based software GPA I and II had excellent agreement. Event analysis showed earlier and greater sensitivity for detecting progression than VFI analysis and both had only moderate agreement. Trend analysis VFI is likely to detect progression in patients with a greater number of visual field tests and a longer follow-up time. The VFI analysis seems to be more accurate than MD analysis for determining rate of progression.
