The diagnostic value of automated flicker threshold perimetry.
Curr Opin Ophthalmol | Published : 1999
Automated perimetry techniques have advanced from the standard white-on-white threshold perimetry to a myriad of perimetric models. These models include motion detection, frequency-doubling contrast sensitivity, and spatial contrast sensitivity perimetry. The research findings for the more popular of the automated perimetry models, in particular those of blue-on-yellow and critical fusion frequency perimetry, are discussed and compared with findings for flicker threshold perimetry. Flicker threshold perimetry demonstrates resistance to such factors as test variability and retinal image blur and has great promise in its ability to detect early visual field loss in the presence of primary open..View full abstract
