This is not true, as there are many blue-eyed cats with perfect hearing. However, white cats with blue eyes do have slightly higher probability of genetic deafness than white cats of other eye colors. [15] White cats having one blue and one other-colored eye are called "odd-eyed" and may be deaf on the same side as the blue eye. [16]
Polycoria is a pathological condition of the eye characterized by more than one pupillary opening in the iris. [1] It may be congenital or result from a disease affecting the iris. [ 1 ] It results in decreased function of the iris and pupil, affecting the physical eye and visualization.
Tonic pupils are fairly common – they are seen in roughly 1 out of every 500 people. A person with anisocoria (one pupil bigger than the other) whose pupil does not react to light (does not constrict when exposed to bright light) most likely has Adie syndrome – idiopathic degeneration of the ciliary ganglion.
Anisocoria is the condition of one pupil being more dilated than the other. Causes. Age. Senile miosis (a reduction in the size of a person's pupil in old age) ...
Anisocoria in the presence of confusion, decreased mental status, severe headache, or other neurological symptoms can forewarn a neurosurgical emergency. This is because a hemorrhage, tumor, or other intracranial mass can enlarge to a size where the third cranial nerve (oculomotor nerve) is compressed, resulting in uninhibited dilatation of the ...
The Pallas's cat (Otocolobus manul), also known as the manul, is a small wild cat with long and dense light grey fur, and rounded ears set low on the sides of the head. Its head-and-body length ranges from 46 to 65 cm (18 to 26 in) with a 21 to 31 cm (8.3 to 12.2 in) long bushy tail.
Length can also vary, although the world's largest Maine Coon cat was recorded as a whopping 48.5 inches long. In fact, Main Coons frequently top the Guinness World Records for world's longest cats.
The pupil diameter can vary greatly due to various factors (primarily the pupillary light reflex), from constriction to as small as 2 mm, to dilation larger than 8 mm in some individuals, though the maximal dilation also varies substantially by individual and decreases with age. The pupil gets wider in the dark and narrower in light.
