Changes in vergence and accommodation parameters after smartphone use in healthy adults
Indian Journal of Ophthalmology, 2021 Purpose: To assess pre and post vergence and accommodation parameters after monitored reading on a smartphone device. Methods: This prospective comparative study was performed in a tertiary eye care center for a duration of 6 months (December 2017 – May ...

Benefits from vergence rehabilitation: evidence for improvement of reading saccades and fixations
Frontiers in Integrative Neuroscience, 2016 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 ...

Frontiers in Human Neuroscience, 2015 PURPOSE: This study examined the relationship between the near dissociated phoria and disparity vergence eye movements. Convergence insufficiency (CI) patients before vergence therapy were compared to: 1) the same patients after vergence therapy and 2 ...

A role of eye vergence in covert attention. [PDF]
PLoS ONE, 2013 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.

Attention-Related Eye Vergence Measured in Children with Attention Deficit Hyperactivity Disorder.
PLoS ONE, 2015 Recent evidence shows a novel role for eye vergence in orienting attention in adult subjects. Here we investigated whether such modulation in eye vergence by attention is present in children and whether it is altered in children with ADHD compared to ...

African Vision and Eye Health, 2015 Comfortable reading and the performance of near point activities involve efficient accommodative and vergence systems. However, accommodative and vergence anomalies are associated with various symptoms that impair efficient near point tasks.

Effect of the accommodation-vergence conflict on vergence eye movements
Vision Research, 2014 With the broader use of stereoscopic displays, a flurry of research activity about the accommodation-vergence conflict has emerged to highlight the implications for the human visual system. In stereoscopic displays, the introduction of binocular disparities requires the eyes to make vergence movements.

Difference in visual processing assessed by eye vergence movements. [PDF]
PLoS ONE, 2013 Orienting visual attention is closely linked to the oculomotor system. For example, a shift of attention is usually followed by a saccadic eye movement and can be revealed by micro saccades.
