Impact of cataract on the results of frequency-doubling technology perimetry

Ophthalmology, 2004
To determine the effect of cataract on the results of frequency-doubling technology (FDT) perimetry.Consecutive cohort study.Forty-four patients with normal ophthalmic examinations, with the exception of cataract, scheduled to undergo phacoemulsification and posterior chamber lens implantation were prospectively identified and completed the study.All ...

Relationship between Indices of Humphrey Perimetry and Frequency Doubling Technology Perimetry in Glaucoma

Journal of Glaucoma, 2004
To study whether the correlation between indices of Humphrey perimetry and Frequency Doubling Technology (FDT) perimetry differs in the early and later stages of glaucoma.This study included 200 eyes of 200 patients with primary open-angle glaucoma or normal-tension glaucoma. The eyes were classified into the early and later stages by the median value (

The Influence of Learning Effect on Frequency Doubling Technology Perimetry (Matrix)

Journal of Glaucoma, 2007
To determine learning effect in healthy patients without perimetric experience, tested with the frequency doubling technology perimetry, with the new model Matrix.Frequency doubling technology in the 30-2 threshold mode was performed on 37 healthy subjects. Each subject was tested twice in different sessions.

Reliability of the First Eye and Second Eye in Frequency Doubling Technology Perimetry

Japanese Journal of Ophthalmology, 2005
To compare the reliability of the perimetry results of the first eye and the second eye with frequency doubling technology (FDT).The subjects were 328 residents who underwent the C-20-5 mode of FDT at a city in central Japan. FDT perimetry was always performed first in the right eye and then in the left eye without any time between tests.

Frequency doubling technology perimetry for detection of glaucomatous visual field loss

American Journal of Ophthalmology, 2000
To evaluate the ability of frequency doubling technology perimetry to detect early, moderate, and advanced glaucomatous visual field loss.In a prospective study, frequency doubling technology perimetry (C-20 full threshold) was performed in the right eye of 254 normal control subjects and 230 patients with early (n = 85), moderate (n = 114), or ...

Optimizing the Use of Frequency Doubling Technology Perimetry in Community Vision Screenings

Optometry and Vision Science, 2008
ABSTRACT Purpose. In recent years, Frequency Doubling Technology perimetry (FDT) has been added to traditional ocular health testing in screening for glaucoma. This study examines a number of strategies to employ FDT in an effort to determine its optimal use in large community screenings.

Frequency Doubling Technology Perimetry With the Humphrey Matrix 30-2 Test

Journal of Glaucoma, 2006
To assess the Humphrey Matrix 30-2 test in detecting functional glaucomatous damage.One eye in each of 60 healthy individuals, 108 patients with ocular hypertension (OHT), and 150 patients with preperimetric (48) or perimetric (102) high-tension primary open-angle glaucoma (POAG) were considered.

Correlation between frequency doubling technology perimetry and temporal frequency characteristics in early glaucoma*

Documenta Ophthalmologica, 2003
To assess the effectiveness of the temporal frequency characteristics (TFC) as an indicator of visual damage in patients with early open-angle glaucoma, TFC obtained from VEPs elicited by a pseudorandom binary sequence (PRBS) stimulus was compared with the frequency doubling technology (FDT) thresholds. Cross power spectrum between the PRBS stimulus as
