The meaning of STEREOACUITY is the ability to detect differences in distance using stereoscopic cues that is measured by the smallest difference in the images presented to the two eyes that can be detected reliably.

Stereopsis is a word derived from Greek language meaning “solid” and “power of sight.” The phenomenon of stereopsis is important for several reasons. In the animal kingdom, having a spare eye if one is damaged is necessary for survival.

Stereoacuity is traditionally considered as the threshold measure of how well an individual can interpret binocular disparity as perceived depth, by determining the spatial correlation of points projected onto the retina.

Stereoacuity, like many forms of hyperacuity, improves with practice. We investigated the effects of repeated measurements over multiple visits on stereoacuity using two commonly utilised clinical stereotests, for both crossed and uncrossed disparity stimuli.

2024年7月4日 · In this chapter, we discuss many of the clinical tests of stereopsis and stereoacuity currently in use. The methodology of the tests, the normative data from these tests, and the clinical significance of these tests will be described.

Among the reduced stereo acuity levels, we found stereoacuity levels as low as 100-200 arc seconds were found in nearly 17.6% of the study population.

2008年5月21日 · To define real change in stereoacuity, we compared performance on 4 tests of stereoacuity (preschool Randot, near Frisby, distance Randot, and the Frisby–Davis distance [FD2] stereoacuity tests) in patients with stable strabismus across 2 …

Given the relevance of the stereoacuity measurement to management choices and functional outcomes, new testing methods would be beneficial to fully assess stereoacuity, both static and dynamic. Keywords: binocular vision; motion in depth; stereoacuity; stereopsis; strabismus.

6 天之前 · Stereoacuity refers to the ability to perceive depth and three-dimensional structures based on binocular disparity. It is a function of how well the brain processes visual information from both eyes to create a perception of depth.

2014年4月15日 · Conclusions: Perceptual learning is effective in improving stereo vision in observers with amblyopia. These results, together with previous evidence, suggest that structured monocular and binocular training might be necessary to fully recover degraded visual functions in amblyopia. Chinese Abstract.
