Comparative Resilience of Clinical Perimetric Tests to Induced Levels of Intraocular Straylight

METHODS. Four healthy young (24–28 years old) observers were tested six times with each perimeter, each time with one of five different WOFs and once without, inducing various levels of IOS (from 10% to 200%). An increase in IOS was measured with a straylight meter. The change in sensitivity from baseline was normalized, allowing comparison of standardized (z) scores (change divided by the SD of normative values) for each instrument.
