Ocular fixation instabilities in motor neurone disease [PDF]
Journal of Neurology, 2009 Objective 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.

Suboptimal eye movements for seeing fine details. [PDF]
, 2018 Human eyes are never stable, even during attempts of maintaining gaze on a visual target. Considering transient response characteristics of retinal ganglion cells, a certain amount of motion of the eyes is required to efficiently encode information and ...

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.

Ocular Volumetry Using Fast High-Resolution MRI during Visual Fixation [PDF]
American Journal of Neuroradiology, 2012 Volumetry may be useful for evaluating treatment response and prognosis of intraocular lesions. Phantom, volunteer, and patient studies were performed to determine whether ocular MR volumetry is reproducible.Half-Fourier single-shot RARE and FSPGR sequences at 1.5T with a 76-mm-diameter surface coil were optimized to obtain still ocular images ...

Can ocular fixations modulate the perception of a bistable logo?
Grafica: Documents de Disseny GràficBistable logos accept two different interpretations, where each interpretation can be conditioned by the area of the image that is being observed. Thus, ocular fixations can affect their final perception.
