Background and scope: Pulsed rising amplitude perimetry (pulsed RAMP) is an improved strategy for automated static perimetry, developed to save examination time without accuracy loss. The aim of this study was to identify characteristic differences between the normal strategy (NS) and the pulsed RAMP strategy in standard automated perimetry, in order to evaluate the potential of the pulsed RAMP for threshold estimation.
Methods: Visual fields from 33 glaucoma patients, 11 controls and 4 patients with other pathology were statistically analysed. A G pattern test using the pulsed RAMP and the NS were performed in randomised order. The MD (mean defect), the sLV (square root of loss variance), the test duration and the point-wise accuracy, related to a calculated reference pre- and post-study visual fields of each patient, were evaluated.
