ABSTRACT Purpose: The Central Vision Analyzer (CVA) is an interactive computer device
that has been reported to measure functional resolution at fixation under contrast and …

Abstract Purpose: The Central Vision Analyzer (CVA) is an interactive, automated computer
device that rapidly thresholds central acuity under conditions mimicking customary photopic …

Purpose: Advances in keratorefractive surgery and optical wave–front analysis make it
essential to quantify subtle decrements and enhancements in visual performance under …

Purpose Many eye diseases require on-going assessment for optimal management,
creating an ever-increasing burden on patients and hospitals that could potentially be …

Methods.: Liquid crystal shutter goggles synchronized with the monitor refresh rate were
used to present a Landolt C and surround bars to one or both eyes, in four viewing …

PURPOSE: Our goal was to examine the accuracy of metrics, calculated using a numerical
eye model including the measurement of the monochromatic aberrations of the eye, to …

Fixation disparity and accommodation were measured while subjects viewed a target on a
cathode ray tube at a 50cm viewing distance. The psychophysical method of sequential …

A major issue in vision in ageing research is how to distinguish between the effects of
changes in the optical and neural systems of the eye on the decline in visual function with …

In bioscience we speak of relative" gold standards." Existing standards for vision tests are
less than ideal. The key standard used in clinical testing and much vision research is visual …

Purpose.: It is challenging to separate the effects of normal aging of the retina and visual
pathways independently from optical factors, decreased retinal illuminance, and early stage …
