Monocular deprivation is an experimental technique used by neuroscientists to study central nervous system plasticity. Generally, one of an animal's eyes is sutured shut during a period of high cortical plasticity (4–5 weeks-old in mice (Gordon 1997)).
Duration depends on the cause of the vision loss. Obscured vision due to papilledema may last only seconds, while a severely atherosclerotic carotid artery may be associated with a duration of one to ten minutes. [6] Certainly, additional symptoms may be present with the amaurosis fugax, and those findings will depend on the cause of the ...
Monocular vision is known as seeing and using only one eye in the human species. Depth perception in monocular vision is reduced compared to binocular vision, but still is active primarily due to accommodation of the eye and motion parallax. The word monocular comes from the Greek root, mono for single, and the Latin root, oculus for eye.
Ocular dominance columns were discovered in the 1960s by Hubel and Wiesel as part of their Nobel Prize winning work on the structure of the visual cortex in cats. Ocular dominance columns have since been found in many animals, such as ferrets, macaques, and humans. [2] Notably, they are also absent in many animals with binocular vision, such as ...
Glaucoma is a progressive condition the eye causes damage to the optic nerve. [7] The damage to the optic nerve is usually caused by intraocular pressure [8] of the eye being elevated. Glaucoma can be seen in dogs, and less commonly, cats. Treatment [9] can be in the form of ocular medication, like prescription eye drops.
Consequently, amblyopia is the world's leading cause of child monocular vision loss, which is the damage or loss of vision in one eye. [59] In the best case scenario, which is very rare, properly treated amblyopia patients can regain 20/40 acuity. [59] Corneal opacification; Degenerative myopia
The gene that causes cats to be white (called the W gene) has incomplete permanence, which is why most cats with white on their coats have it only in patches. As long as the cat has pigmented ...
Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
