[Specificity of suprathreshold test methods in automated perimetry].
The specificity of suprathreshold automated perimetry of the central visual field was investigated comparatively with the Fieldmaster Model 225 computer perimeter, utilizing five different test strategies. The clinical study comprised 30 eyes of 30 healthy subjects. The test strategies were: (1) threshold-related supraluminosity of 5 dB with constant supraluminosity between 0 degrees and 30 degrees eccentricity; (2) threshold-related supraluminosity of 5 dB, increasing the luminosity according to the sensitivity gradient of the retina at 15 degrees eccentricity; (3) threshold-related supraluminosity of 5 dB and stepwise increase of luminosity every 5 degrees of eccentricity; (4) threshold-related supraluminosity of 3 dB and stepwise increase of luminosity every 5 degrees of eccentricity; (5) central stimuli luminosity of 200 asb and stepwise increase of luminosity every 5 degrees of eccentricity. The highest specificity of the visual field examination was obtained with test strategy 3, followed by 5, 4 and 2. The lowest specificity was obtained with test strategy 1.
