Models of Vergence and Accommodation-Vergence Interactions
2002Vergence (or disjunctive) eye movements provide single vision by bringing the images of a bifixation target onto corresponding retinal points in the two eyes. When a target moves in depth, the brain recognizes the change in position of the retinal images and drives the extraocular muscles to bring these images into proper register on the retinas. Since

The binocular visual field is the combined visual field obtained when the eyes are fixating a given point without head movements. The binocular field of fixation is the area within which central bifixation is possible by moving the eyes but not the head.

Fusional vergence in microstrabismus
Documenta Ophthalmologica, 1988The fusional vergence velocity was studied in microstrabismus and in normal persons. In microstrabismus the system works less precisely in that small changes in disparity produce no response, while it is possible that the difference between the amplitude of the stimulus and the amplitude of the response is greater.

Vergence Adaptation in Esotropia
Optometry and Vision Science, 1992Vergence adaptation and anomalous fusional movements have been used by strabismics to overcome prism. There has been controversy in the literature regarding the nature of the vergence responses by esotropes to prism, i.e., fusional, avoidance of fusion, and/or anomalous fusion.

Vergence Adaptation and Senescence
Optometry and Vision Science, 1994The characteristics of prism adaptation have been evaluated by many previous studies but most have been performed on young subjects (typically 18 to 35 years of age). Because little information is available regarding the effect of age on vergence adaptation, we assessed prism adaptation on 25 visually normal subjects across a wide age range (19 to 85 ...

A number of previous investigations have suggested that the relative contribution of proximal vergence to the overall vergence response may increase with age. Accordingly the present study has examined the proximal convergence/test distance (PC/T) ratio in a clinical population of 106 subjects ranging from 6 to 47 years of age.

Unequal Saccades during Vergence
Optometry and Vision Science, 1980An examination of saccades during vergence eye movements (accommodative and disparity) reveals that binocular saccades have unequal magnitudes in each eye, the smaller saccade of each pair opposing the vergence movement. Furthermore, this inequality cannot be explained by linear summation of the saccadic amplitudes onto the ongoing vergence.

The present review aims to discuss the current researches on the ability of the vergence system to adjust to new information. A concomitant or non-concomitant binocular retinal disparity caused by a prism or an anisometropic prescription can be adapted to such that the induced phoria of fixation disparity reduces back to the original value.

Vergence Dynamics Predict Fixation Disparity
Neural Computation, 2001The neural origin of the steady-state vergence eye movement error, called binocular fixation disparity, is not well understood. Further, there has been no study that quantitatively relates the dynamics of the vergence system to its steady-state behavior, a critical test for the understanding of any oculomotor system.
