Description
It has been shown that due to variability, the effective or useful dynamic range for standard automated perimetry (SAP) with Goldmann size III stimuli is about half as large as previously thought1. Size V testing has a substantially larger useful dynamic range with lower variability and is therefore an excellent candidate for detecting visual field change. "Censoring" or not using size III threshold estimates < 20 dB has little effect on the ability to detect glaucomatous progression.2 The effect of stimulus size on the ability to detect visual field progression is unknown. Our goal is to compare the effect of censoring on visual field progression glaucoma with these two stimulus sizes.
