ABSTRACT
This chapter provides an overview of visual function tests for the evaluation of glaucoma. Under standard visual field testing conditions, the normal eye has its greatest sensitivity to light at the fovea. Interpretation of visual field information is aided by statistical, mathematical, and analytic procedures immediately available to the practitioner after patient testing. Glaucoma Progression Analysis establishes the average of two visual field tests as the baseline and compares subsequent follow-up visual field results to this average baseline visual field. The short-wavelength automated perimetry test procedure is designed to isolate and measure visual mechanisms that are particularly sensitive to short-wavelength light. Contrast detection thresholds are determined for a number of test locations in the visual field using a TOP threshold estimation procedure. A variety of different contrast sensitivity tests have also been reported to show sensitivity losses in glaucomatous eyes.
