Ocular dominance, sometimes called eye preference or eyedness, [ 1] is the tendency to prefer visual input from one eye to the other. [ 2] It is somewhat analogous to the laterality of right- or left- handedness; however, the side of the dominant eye and the dominant hand do not always match. [ 3] This is because both hemispheres control both ...
Neuroanatomy of handedness. An estimated 90% of the world's human population consider themselves to be right-handed. [ 1] The human brain's control of motor function is a mirror image in terms of connectivity; the left hemisphere controls the right hand and vice versa. This theoretically means that the hemisphere contralateral to the dominant ...
Left cerebral hemisphere. The lateralization of brain function (or hemispheric dominance[ 1][ 2] / latralisation [ 3][ 4]) is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other. The median longitudinal fissure separates the human brain into two distinct cerebral hemispheres ...
Leber's hereditary optic neuropathy ( LHON) is a mitochondrially inherited (transmitted from mother to offspring) degeneration of retinal ganglion cells (RGCs) and their axons that leads to an acute or subacute loss of central vision; it predominantly affects young adult males. LHON is transmitted only through the mother, as it is primarily due ...
A simulation of the ocular dominance column pattern, as might be seen if the surface of V1 were colored according to eye preference. A typical map of the relationship between ocular dominance, orientation, and cytochrome oxidase. Dark and light areas represent neurons that respond preferentially to the left and right eye.
Duane syndrome is a congenital rare type of strabismus most commonly characterized by the inability of the eye to move outward. The syndrome was first described by ophthalmologists Jakob Stilling (1887) and Siegmund Türk (1896), and subsequently named after Alexander Duane, who discussed the disorder in more detail in 1905.

The term "binocular disparity" refers to geometric measurements made external to the eye. The disparity of the images on the actual retina depends on factors internal to the eye, especially the location of the nodal points, even if the cross section of the retina is a perfect circle. Disparity on retina conforms to binocular disparity when ...
The Edinburgh Handedness Inventory is a measurement scale used to assess the dominance of a person's right or left hand in everyday activities, sometimes referred to as laterality. The inventory can be used by an observer assessing the person, or by a person self-reporting hand use. The latter method tends to be less reliable due to a person ...
