Comparison of conventional and high-pass resolution perimetry in a prospective study of patients with glaucoma and healthy controls.

Abstract
DETECTING VISUAL field progression in open-angle glaucoma remains one of the most important and challenging aspects of glaucoma management. Decisions, such as whether to proceed to surgery, may depend critically on evidence of early and reproducible field progression. Whereas static perimetry has benefited greatly from computerization,1,2 standardization of testing algorithms,3 and development of sophisticated data analysis tools,4,5 it may not be capable of detecting the earliest progression in glaucoma.6,7
