[ 2] The eye that is pointed at an object can alternate. [ 3] The condition may be present occasionally or constantly. [ 3] If present during a large part of childhood, it may result in amblyopia, or ...
Specialty. Ophthalmology. Exotropia is a form of strabismus where the eyes are deviated outward. It is the opposite of esotropia and usually involves more severe axis deviation than exophoria. People with exotropia often experience crossed diplopia. Intermittent exotropia is a fairly common condition. "Sensory exotropia" occurs in the presence ...
Cerebral achromatopsia. Cerebral achromatopsia is a type of color blindness caused by damage to the cerebral cortex of the brain, rather than abnormalities in the cells of the eye's retina. It is often confused with congenital achromatopsia but underlying physiological deficits of the disorders are completely distinct.
Stereopsis recovery, also recovery from stereoblindness, is the phenomenon of a stereoblind person gaining partial or full ability of stereo vision ( stereopsis ). Recovering stereo vision as far as possible has long been established as an approach to the therapeutic treatment of stereoblind patients. Treatment aims to recover stereo vision in ...
Bálint's syndrome. Bálint's syndrome is an uncommon and incompletely understood triad of severe neuropsychological impairments: inability to perceive the visual field as a whole ( simultanagnosia ), difficulty in fixating the eyes ( oculomotor apraxia ), and inability to move the hand to a specific object by using vision ( optic ataxia ).

Suppression of an eye is a subconscious adaptation by a person's brain to eliminate the symptoms of disorders of binocular vision such as strabismus, convergence insufficiency and aniseikonia. The brain can eliminate double vision by ignoring all or part of the image of one of the eyes. The area of a person's visual field that is suppressed is ...
Traumatic brain injury is defined as damage to the brain resulting from external mechanical force, such as rapid acceleration or deceleration, impact, blast waves, or penetration by a projectile. [ 10] Brain function is temporarily or permanently impaired and structural damage may or may not be detectable with current technology.
New cases of strabismus in adults can be caused by head injuries or accidents, damage to the eye muscles or nerves during surgery, or health problems such as diabetes, brain tumors, or stroke ...
