PURPOSE To determine which measures of the binocular visual field correlate best with the patient's assessment of vision. METHODS Esterman binocular visual field testing and four other binocular visual field tests (designated peripheral 20 dB [p20], peripheral 22 dB [p22], central 24 dB [c24] and central 26 dB [c26]) were performed in 101 patients with glaucoma or suspected glaucoma. Scores f...

For simultaneous testing for differences in location, scale, symmetry (or skewness) and tailweight between two unknown continuous distribution functions, a statistic V is proposed. Its quantiles are estimated by the bias-corrected bootstrap. Monte Carlo studies show that the V -test tends to be more robust than its competitor. Asymptotics to justify the use of the bootstrap are presented. The m...

The aim of this study was to explore the plasticity of fixation in patients with central vision loss. Most of these patients use preferred retinal loci (PRLs) in the healthy eccentric part of the retina to fixate, but fixation stability and retinal location are not always optimal for best visual performance. This study examined whether fixation stability and a new PRL location can be trained an...

PURPOSE To investigate the effect of perimetrists' instructions on automated perimetry thresholds. METHODS Eighteen volunteers in two age groups participated in a series of three test sessions. Each session consisted of a Humphrey Field Analyzer 30-2 test, a questionnaire, and a customized test program using a Humphrey perimeter to construct frequency of seeing (FOS) curves from which thresho...
