Short-term adaptation of accommodation, accommodative vergence and disparity vergence facility

, 2012
Previous studies have found that subjects can increase the velocity of accommodation using visual exercises such as pencil push ups, flippers, Brock strings and the like and myriad papers have shown improvement in accommodation facility (speed) and ...

Effect of visual attention and horizontal vergence in three-dimensional space on occurrence of optokinetic nystagmus

Journal of Eye Movement Research, 2019
OKN corresponding to the motion of the fixating area occurs when a stimulus has two areas separated in depth containing motion in different directions.

Walsh & Hoyt: Vergence

, 2005
Summary. Vergence eye movements permit stereopsis and prevent diplopia by moving the eyes in opposite horizontal directions. The vergence system maintains the image of an object on the fovea of each eye whether the object is located far away or nearby ...

Bedside Assessment of Vergence in Stroke Patients

, 2021
Background:Given the widely distributed network of midbrain, pontine, cerebellar, and cortical areas involved in the neural control of vergence, one might expect various vergence deficits in stroke patients.

Vergence Movements in Comitant Strabismus

, 1990
Vergence movements induced by base-out prisms were recorded, with an infrared eye tracker, for 6 patients with comitant esotropia (i.e., convergent strabismus) and anomalous retinal correspondence and for 6 normal subjects.

Disparity vergence responses before versus after repetitive vergence therapy in binocularly normal controls

, 2016
This study sought to determine whether significant changes would be observed between vergence eye movements before and after 12 hr of repetitive vergence therapy (1 hr per day on different days) in subjects with normal binocular vision compared to ...

Interaction between Accommodation and Vergence on Distance Perception

i-Perception, 2011
Fisher and Ciuffreda (1988) and Mon-Williams and Tresilian (1999) reported that, without vergence cue, diopter change in accommodation induced change in apparent distance. Meanwhile, there is conflicting evidence about the relative roles of accommodation

Proximal vergence and perceived distance

, 1986
The purpose of this study was to measure the vergence response to a change in physical distance (proximal vergence) and to evaluate its presumed stimulus, change of perceived distance.
