Comparison of three tests using the frequency doubling illusion to diagnose glaucoma

Maddess, Ted; Severt, W; Stange, Gert


Purpose: The introduction of the FDT perimeter prompted the comparison of three tests employing frequency doubling (FD) stimuli. These measures compared different visual field locations and contrast ranges. Frequency of seeing curves were examined for the method most similar to FDT.
