Comparison of visual field test results obtained through Humphrey matrix frequency doubling technology perimetry versus standard automated perimetry in healthy children

open access: yesIndian Journal of Ophthalmology, 2013
Aims : The aim of this study was to compare the visual field test results in healthy children obtained via the Humphrey matrix 24-2 threshold program and standard automated perimetry (SAP) using the Swedish interactive threshold algorithm (SITA)-Standard

Comparison of Standard Automated Perimetry, Short-Wavelength Automated Perimetry, and Frequency-Doubling Technology Perimetry to Monitor Glaucoma Progression. [PDF]

open access: yesMedicine (Baltimore), 2016
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 ...

Frequency doubling technology perimetry for neuro-ophthalmological diseases. [PDF]

open access: yesBr J Ophthalmol, 2004
It will be beneficial to all eye care practitioners if investigations of a wide variety of ocular and neurological diseases are evaluated with FDT perimetry In the past decade, there have been many advances in diagnostic test procedures for evaluation of structural and functional changes affecting the visual pathways.

Usefulness of frequency doubling technology perimetry 24-2 in glaucoma with parafoveal scotoma. [PDF]

open access: yesMedicine (Baltimore), 2017
The standard automated perimetry (SAP) 24-2 test cannot adequately test the paracentral region because test points are located sparsely in macular area where is crowded with retinal ganglion cells (RGCs), even though paracentral scotoma is clinically related to a risk of losing visual function.

Prediction of future scotoma on conventional automated static perimetry using frequency doubling technology perimetry. [PDF]

open access: yesBr J Ophthalmol, 2006
To see if scotoma detected with frequency doubling technology (FDT) is confirmed by Humphrey field analyser (HFA) 3 years later.Subjects were first examined with the screening C-20-1 program of FDT. The visual field was examined annually for 4 years using HFA program C30-2.

Frequency-Doubling Technology Perimetry and Optical Defocus

open access: yesInvestigative Opthalmology & Visual Science, 2003
The frequency-doubling technology (FDT) perimeter has no provision for introducing corrective lenses, save for the patient's spectacles, and so patients are sometimes tested in the presence of moderate levels of defocus. The effect of defocus on frequency-doubling (FD) sensitivity was determined for both the commercially available instrument and for ...
