purpose. Variation in stereoacuity was examined in a large group of observers with Snellen
acuity of 20/30 or less. methods. Threshold retinal disparity for 2.78× 2.28 rectangular test …

Purpose. Because previous studies have reported conflicting evidence, we examined a
possible difference in stereoacuity between distance and near, in particular using a random …

Aim: To examine how stereoacuity changes with age as measured by a variety of
stereotests. Methods: Stereoacuity has been measured in 60 normal subjects aged 17–83 …

Stereoacuity was measured in 30 subjects with a naturally occurring visual acuity (VA)
difference between the eyes. The stereoacuity was measured by a modified Howard's …

We measured stereoacuity in 41 subjects with normal Snellen acuity in each eye, and
normal ocular health. Patients were measured in each of the age ranges 21–28, 41–49, 51 …

PURPOSE: To develop a presentation protocol for the new Frisby-Davis 2 (FD2) distance
stereoacuity test. DESIGN: Prospective data collection. METHODS: Stereoacuity was tested …

Background: There is a need for a stereotest with the following properties:(1) Natural
viewing conditions, ie stimulus contours visible for each eye alone, but no or hardly any cue …

Three experiments investigated whether and to what extent increases in age affect the
functionality of stereopsis. The observers' ages ranged from 18 to 83 years. The overall goal …

Stereoscopic depth perception utilizes the disparity cues between the images that fall on the
retinae of the two eyes. The purpose of this study was to determine what role aging and …

The improvement in stereoacuity of two inexperienced, normal subjects was compared at
foveal and at 2.5° and 5° peripheral target locations as a function of practice. Outlines of two …
