Journal Article
Detecting early glaucoma by assessment of retinal nerve fiber layer thickness and visual function.

TL;DR: In this article, the authors compared the abilities of scanning laser polarimetry, optical coherence tomography (OCT), short-wavelength automated perimetry (SWAP), and frequency-doubling technology (FDT) perimetric to discriminate between healthy eyes and those with early glaucoma.

Linking Structure and Function in Glaucoma
TL;DR: The proposed model for linking structure and function in glaucoma has provided information that is important in understanding the results of standard clinical testing and the neuronal losses caused by glau coma, which may have clinical application for inter-test comparisons of the stage of disease.

Neural losses correlated with visual losses in clinical perimetry.

TL;DR: With retinal eccentricity as a factor, the neural losses from glaucoma are predictable from visual sensitivity measurements by clinical perimetry, and the model produced accurately predict the rate of age-related losses of retinal ganglion cells in humans, based on the normativePerimetry data for age- related reductions in visual sensitivity.
Journal ArticleDOI
Severity of Visual Field Loss and Health Related Quality of Life
TL;DR: HRQOL is diminished even in persons with relatively mild VFL on the basis of MD scores, and prevention and management of persons with VFL may be important in preventing or reducing poor HRQOL related to difficulties in driving, distance and peripheral vision activities, and a sense of dependency.
Journal ArticleDOI
Frequency doubling technology perimetry abnormalities as predictors of glaucomatous visual field loss
TL;DR: Functional abnormalities detected by FDT perimetry were predictive of the future onset and location of SAP visual field loss among glaucoma suspect patients.

Chronic Human Glaucoma Causing Selectively Greater Loss of Large Optic Nerve Fibers
TL;DR: It is confirmed that the death of a substantial proportion of optic nerve fibers precedes detectable visual field loss and that no fiber size was completely spared at any stage of atrophy.
Journal Article
Chronic glaucoma selectively damages large optic nerve fibers.
TL;DR: Fibers larger than the normal mean diameter atrophied more rapidly in glaucomatous eyes, though no fiber size was spared from damage, and larger fibers were lost preferentially even in areas of the optic nerve with mild damage, indicating their inherent susceptibility to injury byglaucoma.

Screening for glaucomatous visual field loss with frequency-doubling perimetry.
Chris A. Johnson,S J Samuels +1 more
TL;DR: Preliminary results indicate that the frequency-doubled contrast test provides a quick, efficient means of screening for glaucomatous visual field loss and the use of the MOBS staircase procedure and small, localized stimuli result in the best performance for screening purposes.
Journal ArticleDOI
A new generation of algorithms for computerized threshold perimetry, SITA
TL;DR: New methods which take available knowledge of visual field physiology and pathophysiology into account are applied, and modern computer-intensive mathematical methods for real time estimates of threshold values and threshold error estimates are applied.
Journal ArticleDOI
Frequency Doubling in Visual Responses
TL;DR: The frequency-doubling effect is the result of neural mechanisms which are more central than the locus of flicker fusion, and can be explained by assuming that there is a second filtering operation which follows the nonlinear response of the visual system, rather than preceding it.
