Saccades and vergence performance in a population of children with vertigo and clinically assessed abnormal vergence capabilities. [PDF]
PURPOSE: Early studies reported some abnormalities in saccade and vergence eye movements in children with vertigo and vergence deficiencies. The purpose of this study was to further examine saccade and vergence performance in a population of 44 children (

Central crosstalk for somatic tinnitus: abnormal vergence eye movements. [PDF]
BACKGROUND: Frequent oulomotricity problems with orthoptic testing were reported in patients with tinnitus. This study examines with objective recordings vergence eye movements in patients with somatic tinnitus patients with ability to modify their ...

Accuracy of formulae for secondary intraocular lens power calculations in pediatric aphakia
Purpose: To compare the accuracy of axial length vergence formulas versus refractive vergence formulas for secondary intraocular lens (IOL) implantation in pediatric aphakia. Methods: This retrospective comparative study, evaluated 31 eyes of 31 patients

Differentiation between vergence and saccadic functional activity within the human frontal eye fields and midbrain revealed through fMRI. [PDF]
Eye movement research has traditionally studied solely saccade and/or vergence eye movements by isolating these systems within a laboratory setting. While the neural correlates of saccadic eye movements are established, few studies have quantified the ...

A role of eye vergence in covert attention. [PDF]
Covert spatial attention produces biases in perceptual and neural responses in the absence of overt orienting movements. The neural mechanism that gives rise to these effects is poorly understood.

Bidirectional Synergistic Vergence [PDF]
A 14-year-old boy presented with left ptosis and squint since his childhood. In primary position he had left hypotropia with ptosis (levator function 2 mm). With elevation of the right eye, the left eye depresses and adducts; with depression of the right eye, the left eye elevates and abducts. Forced duction test revealed no restrictive pattern.

Differential diagnosis of vergence and saccade disorders in dyslexia
Previous studies suggest vergence and saccade abnormalities in dyslexic adolescents. However, these studies are mainly clinically based and do not provide objective measurements of eye movements, but rather subjectively evaluate vergence using haplosopic

Error Correction in Vergence Eye Movements: Evidence Supporting Hering’s Law
In pure symmetrical vergence eye movements, a fusion initiating component quickly brings the eyes close to the desired position. A small error usually remains after this response which must be corrected to attain the small final vergence error (i.e ...
