Horopter
Definition:
(n.) The line or surface in which are situated all the points which are seen single while the point of sight, or the adjustment of the eyes, remains unchanged.
Example Sentences:
(1) An additional subject showed irregular alterations in vergence posture during nonius horopter measurements.
(2) The results of our physiological analysis in the burrowing owl (Speotyto cunicularia) also reveal a tilted horopter in this terrestrial avian species.
(3) Determining the mean of several sets of replications smoothed out the horopter.
(4) The depth data suggests that, at least in the near field, the zero value for relative depth lies at the same absolute depth as the stereo horopter (locus of zero stereo disparity).
(5) In addition to localized irregularities in the horopter locus, shifts in fixation disparity produced regional distortions of the horopter.
(6) For normal subjects with good stereopsis the equidistance (stereoscopic distance matching) horopter shape was altered with the application of lateral prism.
(7) Regardless of spatial frequency, stereo sensitivity declined rapidly as stimuli were presented away from the horopter.

(9) Horopters in exotropes appear to be very similar to those found in normal binocular subjects.
(10) The width of these disparity tuning functions varied from 5 arc min for adaptation at the horopter to 20 arc min for adaptation at 20 arc min disparity.
(11) However, the mean standard error of the means of several replications produced a more nearly smooth horopter locus.
(12) There is a gradual increase in stereo-threshold as the targets are moved out along the horopter, away from the fixation point into the peripheral visual field.
(13) Relative depth discrimination is, then, operative over a very wide band of visual space around the horopter (about 3 deg of absolute disparity in the centre of the visual field and even more in the periphery).5.
(14) The horopter (the locus of targets that appear to be fused binocularly) is the region of maximum stereoacuity and this does not necessarily coincide with the Vieth-Müller circle (the locus of zero geometric or absolute disparity).
