Modeling the relative influence of fixation and sampling errors on retest variability in perimetry
BACKGROUND: Our previous studies have shown that in standard automated perimetry (SAP) undersampling occurs if sensitivity varies across a visual field faster than the Nyquist rate (Nq) for the standard sampling interval of 6°. This undersampling was shown to be a major source of test-retest variability. This study first tests some of the assumptions of the undersampling idea, and then determines the relative contributions to test-retest variability of normal eye movements and undersampling....[Show more]
