Induced vergence-accommodation conflict reduces cognitive performance in the Stroop test.

Interaction mechanisms between cognition and binocular motor control in reading saccades remain unclear. In this study we examine objectively saccades and fixations parameters during the Stroop test, involving three different levels of cognitive demand (reading, color denomination and interference). In addition, we experimentally induce accommodation and vergence conflicts during the different tasks.

Effects of Pure Vergence Training on Initiation and Binocular Coordination of Saccades.

Purpose: We hypothesized that saccade eye movement properties, particularly latency and binocular coordination, depend on vergence quality.

Methods: We studied 11 students clinically diagnosed for vergence disorders versus 8 healthy controls. Rehabilitation of vergence disorders was done with a novel research-based method, using vergence in midsagittal plane.

Benefits from Vergence Rehabilitation: Evidence for Improvement of Reading Saccades and Fixations.

We hypothesize that binocular coordination of saccades is based on continuous neuroplasticity involving interactions of saccades and vergence. To test this hypothesis we study reading saccades in young students who were diagnosed for vergence disorders before and after vergence rehabilitation. Following orthoptic evaluation and symptomatology screening, 5 weekly sessions of vergence rehabilitation were applied with the REMOBI vergence double step protocole (see Kapoula et al.

Objective Evaluation of Vergence Disorders and a Research-Based Novel Method for Vergence Rehabilitation.

Purpose: We performed video-oculography to evaluate vergence eye movement abnormalities in students diagnosed clinically with vergence disorders. We tested the efficiency of a novel rehabilitation method and evaluated its benefits with video-oculography cross-correlated with clinical tests and symptomatology.

Methods: A total of 19 students (20-27 years old) underwent ophthalmologic, orthoptic examination, and a vergence test coupled with video-oculography.

Binocular Vision and the Stroop Test.

Purpose: Recent studies report a link between optometric results, learning disabilities, and problems in reading. This study examines the correlations between optometric tests of binocular vision, namely, of vergence and accommodation, reading speed, and cognitive executive functions as measured by the Stroop test.

Methods: Fifty-one students (mean age, 20.

Tissue factor activity is upregulated in human endothelial cells exposed to oscillatory shear stress.

Hemodynamic forces play a critical role in the pathogenesis of atherosclerosis as evidenced by the focal nature of the disease. Oscillatory shear stress characterizes the hemodynamic environment of plaque-prone areas as opposed to unidirectional shear stress typical of plaque-free areas. These particular flow conditions modulate atherosclerosis-related genes.

[Clinical aspects of acne].

Acne is the most current disease in clinical practice for dermatologist offices, where 15 to 20% of consultation have to deal with. If juvenile polymorphous acne is the most classical form, new aspects has been enhanced during these late years. Acne in new borns, prepubertal acne with hormonal secretions from surrenalians glands, late acne starting after 25 years, and leading to specific hormonal testing have been emphaized.
