Frequency. ~2% (children) [ 3] Strabismus is a vision disorder in which the eyes do not properly align with each other when looking at an object. [ 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 ...
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 ...
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 ...
Stereoblindness (also stereo blindness) is the inability to see in 3D using stereopsis, or stereo vision, resulting in an inability to perceive stereoscopic depth by combining and comparing images from the two eyes . Individuals with only one functioning eye have this condition by definition since the visual input of the second eye does not ...
Stereopsis. Stereopsis (from Ancient Greek στερεός ( stereós) 'solid' and ὄψις (ópsis) 'appearance, sight') is the component of depth perception retrieved through binocular vision. [ 1] Stereopsis is not the only contributor to depth perception, but it is a major one. Binocular vision happens because each eye receives a different ...
The management of strabismus may include the use of drugs or surgery to correct the strabismus. Agents used include paralytic agents such as botox used on extraocular muscles , [1] topical autonomic nervous system agents to alter the refractive index in the eyes, and agents that act in the central nervous system to correct amblyopia.
Chronic progressive external ophthalmoplegia ( CPEO) is a type of eye disorder characterized by slowly progressive inability to move the eyes and eyebrows. [ 1] It is often the only feature of mitochondrial disease, in which case the term CPEO may be given as the diagnosis. In other people suffering from mitochondrial disease, CPEO occurs as ...
Hypertropia is a condition of misalignment of the eyes ( strabismus ), whereby the visual axis of one eye is higher than the fellow fixating eye. Hypotropia is the similar condition, focus being on the eye with the visual axis lower than the fellow fixating eye. Dissociated vertical deviation is a special type of hypertropia leading to slow ...
