Eye movements. Eye movements are important behaviors for locating and tracking objects in the visual world. Two of the major types of eye movements are saccades and smooth pursuit. Saccades are very rapid and precise eye movements between two positions, and are important in establishing fixation. Smooth pursuit on the other hand, allows the ...
Two images of the same child. The top image shows the left eye slightly cross-eyed. This is fixed in the bottom picture by stretching the extra skin around the eye.

Specialty. Neurology. Frequency. 1 in 4000 [1] Photosensitive epilepsy ( PSE) is a form of epilepsy in which seizures are triggered by visual stimuli that form patterns in time or space, such as flashing lights; bold, regular patterns; or regular moving patterns. PSE affects approximately one in 4,000 people (5% of those with epilepsy).
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. The species in which fixational eye movement has been verified thus far include ...
Automatism (medicine) Automatism is a set of brief unconscious or automatic behaviors, [1] typically at least several seconds or minutes, while the subject is unaware of actions. This type of automatic behavior often occurs in certain types of epilepsy, such as complex partial seizures in those with temporal lobe epilepsy, [2] or as a side ...
