Ocular fixation instabilities in motor neurone disease [PDF]

Journal of Neurology, 2009
Eye movements are classically felt to be spared in motor neurone disease (MND). Although a range of ocular motor disorders have been reported, no consistent pattern has been established. Disturbances of ocular fixation have been noted in MND; however, fixation has not yet been formally examined. With the recent characterization of ocular fixation using

Investigating eye movement acquisition and analysis technologies as a causal factor in differential prevalence of crossed and uncrossed fixation disparity during reading and dot scanning [PDF]

, 2013
Previous studies examining binocular coordination during reading have reported conflicting results in terms of the nature of disparity (e.g. Kliegl, Nuthmann, & Engbert (Journal of Experimental Psychology General 135:12-35, 2006); Liversedge, White ...

Towards safer non-volatile tissue fixatives: Evaluation of choline-based ionic liquids for fixing ocular tissues

Ecotoxicology and Environmental Safety, 2021
Volatile organic chemicals (VOCs) are routinely used for processing biological tissue samples in clinical laboratories. Recognizing their serious health and environmental impacts, a few non-volatile green solvents (choline based ionic liquids, ILs) were ...

Pathophysiology of ocular surface squamous neoplasia. [PDF]

, 2014
The incidence of ocular surface squamous neoplasia (OSSN) is strongly associated with solar ultraviolet (UV) radiation, HIV and human papilloma virus (HPV). Africa has the highest incidence rates in the world.

The joint contributions of saccades and ocular drift to repeated ocular fixations

Vision Research, 2001
We measured the joint contributions of different sized saccades and ocular drift to overall performance in an alternating fixation task. Subjects repeatedly shifted fixation between the centres of a pair of bars of width 2 degrees -2 arc min, either mentally selected or electronically cut from a stationary sine grating display.

The prevalence of poor ocular motilities in a mainstream school compared to two learning-disabled schools in Johannesburg

African Vision and Eye Health, 2016
Background: Ocular motilities play a major role when reading for the continuous acquisition and updating of visually presented information. Accurate oculomotor control is required to be able to learn how to read and to efficiently read to learn.
