Normal values of short-wavelength automated perimetry.
BACKGROUND The purpose of this study was to evaluate short-wavelength automated perimetry (SWAP, i.e., blue-yellow) in normal volunteers and to review the current normal values provided by the manufacturer. METHODS 28 eyes of 28 normal subjects (age range 21-48 years, mean age 36.5 years) had SWAP (Octopus 101, two phases of program G2, Interzeag AG, Schlieren, Switzerland). All subjects had ...
متن کاملA new rapid threshold algorithm for short-wavelength automated perimetry.
PURPOSE To develop and test a short and reliable visual field threshold program for the early detection of glaucomatous visual field loss, by adapting the Swedish interactive test algorithm (SITA) to short-wavelength-automated-perimetry (SWAP). METHODS Computer simulations were performed to test the accuracy of several versions of SITA SWAP, and to optimize speed versus reliability. The selec...
متن کاملComparison of standard automated perimetry, frequency-doubling technology perimetry, and short-wavelength automated perimetry for detection of glaucoma.
PURPOSE To compare the performance of standard automated perimetry (SAP), frequency-doubling technology (FDT) perimetry, and short-wavelength automated perimetry (SWAP) in detecting glaucoma. METHODS One hundred thirty-two eyes of 95 glaucoma patients and 37 normal subjects had retinal nerve fiber layer (RNFL) imaging and visual field testing by SAP, Matrix FDT perimetry, and Swedish interact...
متن کاملComparison of Standard Automated Perimetry, Short-Wavelength Automated Perimetry, and Frequency-Doubling Technology Perimetry to Monitor Glaucoma Progression
Detection of progression is paramount to the clinical management of glaucoma. Our goal is to compare the performance of standard automated perimetry (SAP), short-wavelength automated perimetry (SWAP), and frequency-doubling technology (FDT) perimetry in monitoring glaucoma progression.Longitudinal data of paired SAP, SWAP, and FDT from 113 eyes with primary open-angle glaucoma enrolled in the D...
متن کاملWAVELENGTH AUTOMATED PERIMETRY ( SWAP ) Chris
The pioneering work of Stiles provided a means of psychophysically isolating and measuring the sensitivity of individual color vision mechanisms through the two-color increment threshold procedure. Basically, this approach involved decreasing the sensitivity of some color vision mechanisms (termed π mechanisms by Stiles) by using a chromatic adapting background light, and then measuring the sen...
