When one eye is misaligned, the brain continues to see two images rather than the combined image. In a young child, the brain learns to see only the image from the eye pointed ahead, ignoring the ...
Feline corneal sequestrum (also known as feline corneal necrosis) is the development of dark areas of dead tissue in the cornea of domestic cats. This disease is painful to the cat, although it develops slowly over a longer period of time. Cats will usually demonstrate teary eye(s), squinting or closing of the eye(s), and covering of the third ...
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 ...
A rare predominantly black cat with odd eyes. The odd-eyed colouring is caused when either the epistatic (recessive) white gene or dominant white (which masks any other colour genes and turns a cat completely white, solid white) [3] or the white spotting gene (which is the gene responsible for bicolour coats) [4] prevents melanin granules from reaching one eye during development, resulting in ...
Cats' eyes are largely similar to ours but with some fascinating differences, and one thing they have that we don't is a third, inner eyelid, called the nictitating membrane. When a cat blinks it ...
A recent study from researchers at Oakland University in Michigan suggests that cats do indeed grieve the loss of other pets - yes, even dogs. People Magazine covered the findings from the Oakland ...
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 lazy eyes, and loss of depth ...
Micropsia is a condition affecting human visual perception in which objects are perceived to be smaller than they actually are. Micropsia can be caused by optical factors (such as wearing glasses), by distortion of images in the eye (such as optically, via swelling of the cornea or from changes in the shape of the retina such as from retinal edema, macular degeneration, or central serous ...
