More commonly known as crossed-eyes, is a vision condition in which a person cannot align both eyes simultaneously under normal conditions One or both of the eyes may turn in, out, up or down An eye turn may be constant; when the eye turns all of the time Strabismus may be intermittent; turning only some of the time, such as, under stressful situations or when ill
Also known as crossed eyes Visual defect in which the eyes are misaligned and point in different directions Strabismus usually occurs in childhood but can occur later in life Children with crossed eyes usually adapt when the brain learns to ignore the image of the misaligned eye, although they lose depth perception Adults who develop the problem often have double vision because the brain is already trained to see two images
or squint or heterotropia Failure of the eyes to align properly to focus on an object. The affected eye may deviate in any direction, including inward (cross-eye) or outward (walleye). Problems with photoreception or the nerves that relay images to the brain cause a constant degree of deviation (comitant); defects in the nerves that control the muscles that move the eyes cause deviation that varies with the direction of gaze (noncomitant). Both types impede development of a child's ability to focus the eyes and merge images from the two retinas into one (fusional reflex). The brain suppresses the image from the deviant eye, which may become functionally blind. Treatment may involve exercises to strengthen the weak eye or surgery or both
Affects approximately 4 out of every 100 children It is a visual defect in which the two eyes point in different directions One eye may turn either in, out, up, or down while the other eye aims straight ahead Due to this condition, both eyes do not always aim simultaneously at the same object This results in a partial or total loss of stereo vision and binocular depth perception The eye turns may be visible at all times or may come and go In some cases, the eye misalignments are not obvious to the untrained observer
The condition that occurs when the two eyes do not align together resulting in double vision or the blocking of one eye's visual image to the brain
An affection of one or both eyes, in which the optic axes can not be directed to the same object, a defect due either to undue contraction or to undue relaxation of one or more of the muscles which move the eyeball; squinting; cross-eye
Strabismus occurs when one eye does not aim directly at an object of interest to which the other eye is aimed The eye turn may be present always or only occasionally, and the turn may be directed inward toward the nose (crossed eye) or outward to the side (wall eye) Untreated, this condition can lead to amblyopia (Prevent Blindness America)
Lack of alignment of the two eyes such that both eyes do not point at the object being viewed Commonly termed "cross-eyed" or "wall-eyed," one eye could either be turned inward or outward in relation to the other
deviation of the eye which the patient cannont overcome The visual axes assume a position relative to each other different from that required by the physiological conditions [normal binocular vision] The various forms of strabismus are spoken of as tropias, their direction being indicated by the appropirate prefix, as hypertropia, and esotropia, exotropia, cyclotropia, hypotropia
Crossed eyes, eg esotropia (one eye turning in), exotropia (one eye turning out) or hypertropia (one eye higher than the other)
Both eyes cannot be directed at the same object (binocular vision), because of an imbalance in one or more of the muscles that move the eyes Double vision results and if left untreated the brain learns to ignore the vision from the weaker eye Children with parts of there retina missing from Coloboma may have this conditon Their brain is trying to find good retina material to focus an image on
heterotropia or tropia; inability to attain or maintain binocular vision due to some type of muscle imbalance in one eye, causing that eye to turn in, out, up, or down relative to the other eye; can be "intermittent" (occurring sometimes), "constant" (occurring all the time), and/or "alternating" (occurring sometimes with one eye and sometimes with the other eye, whether intermittently or constantly)
— Also known as "cross eyes " One or both eyes turn in, out, up or down, independent of the other eye (NERF) - The condition in which binocular fixation is not present under normal seeing conditions, i e the line of sight of one eye does or does not intersect the other at the object of fixation Also commonly referred to as "crossed eyes "
A condition of abnormal alignment of one eye in relation to the other Esotropia and crossed eyes are types of strabismus
