The vergence horopter

Vision Research, 2021
The horopter is defined by the criterion with which it is measured; these include the apparent frontoparallel plane, the region of binocular single vision, and identical visual direction. Another criterion is one that "the positions of the points are such that none provides a stimulus for fusional movement of the eyes".

Tonic Vergence and Vergence Adaptation

Optometry and Vision Science, 1997
In the absence of an adequate visual stimulus, the eyes are typically converged by approximately 0.25 to 0.75 meter angles (MA). This vergence response (VR) was believed to reflect the level of tonic innervation to the extraocular muscles, and accordingly has been termed tonic vergence (TV).

Vergence adaptation in clinical vergence testing

Optometry - Journal of the American Optometric Association, 2010
The purposes of this investigation were to determine whether vergence adaptation occurs after vergence range testing and vergence facility testing and to determine whether vergence adaptation correlates with the results of these tests.Thirty subjects participated in 3 testing sessions on different days. During each session 1 of the following was tested:

Vertical vergence movements

Documenta Ophthalmologica, 1981
In a preliminary report (Houtman et al., 1977) some of the characteristics of vertical vergence movements were mentioned. One of the most striking features appeared to be their slowness, compared to the horizontal disjunctive eye movements. This is a report of further studies on the dynamic characteristics of the vertical disjunctive eye movements ...

Frequency analysis of accommodation, accommodative vergence and disparity vergence

Vision Research, 1973
Abstract Engineering control analysis is used to gain some insight into the nature of the prediction operator and the synkinesis in the near response triad. The frequency characteristics of accommodation, accommodative vergence and disparity vergence systems are compared on a single subject.

Vergence eye movements

Documenta Ophthalmologica, 1974
The extensive and scattered literature on vergence eye movements is reviewed. Topics covered include the neural innervation to vergence, active versus passive divergence, muscular control, the accuracy of vergence, the interaction from vergence to accommodation, the independence of vergence and version, the sharing of responsibility with other eye ...
