Fixation visual
WebBackground: The ability to keep steady fixation on a target is one of several aspects of good visual function. However, there are few reports on visual fixation during childhood … WebVisual fixation has been suggested to be no more than pursuit of a target at zero velocity. We can fixate just using slow movements without saccades. While pursuit may play a …

This was described by the French ophthalmologist Louis Émile Javal in the late 19th century. He reported that eyes do not move continuously along a line of text, but make short, rapid movements intermingled with short stops ().Javal's observations were characterised by a …
Fixation or visual fixation is the maintaining of the gaze on a single location. An animal can exhibit visual fixation if it possess a fovea in the anatomy of their eye. The fovea is typically located at the center of the retina and is the point of clearest vision.
