Testing for Glaucoma with the spatial frequency doubling illusion

Maddess, Ted; Goldberg, Ivan; Dobinson, Jeffrey; Wine, Stephen; Welsh, Alan; James, Andrew

Description

We examined the performance of tests for glaucoma based on the spatial frequency doubling (FD) illusion. Contrast thresholds for seeing the FD illusion in four large visual field regions were measured from 340 subjects who were tested up to seven times over 2 years. Median sensitivities of 91% at specificities of 95% were obtained. Test-retest variability for the worst hemifield thresholds averaged 2.22 db±0.09 S.E. for all tested groups, and significant progression was observed for glaucoma...[Show more]
