The pupil is the central holes in the iris, is the passage of light enter the eye. A normal pupil is round, both sides of the other large, diameter 25 mm, color, like a pool of well water, dark overhead, the Qing Zhan Zhan's. If the pupil sphincter contraction, then the pupil to narrow, dominated by the oculomotor nerve of the parasympathetic nervous system; pupil dilation muscle contraction, then the pupil dilated by the sympathetic innervation. The pupil can change in the intensity of light to narrow or expanded. In normal indoor lighting, if the pupil diameter of less than 1.5 mm or greater than 5 mm, irregular margins, unresponsive to light, etc. are all sick.
White pupil
Found in cataract, iridocyclitis, glaucoma, high myopia, or systemic diseases such as diabetes, complications such as hand, foot and convulsions can also be caused by trauma. More is to see a senile cataract, according to statistics, the causes of cataract blindness accounted for first. Suffering from cataract, you can find through the cornea where the pupil appears white, this is because the lens opacities occurred reasons. Old people with diabetes or eye trauma, can cause cataracts. If the pupil found himself white, should go to ophthalmology, internal medicine to do detailed inspection.
Pupil yellowing
By torch light or lights and the pupil, fundus depths of the issue of a yellow cat's eye reflex, like the night, the doctor said the type of eye as "amaurotic cat's eye", mostly retinoblastoma performance. Most of these eye diseases seen in children 7-8 years of age, there is a certain degree of familial and genetic nature of high grade, if not treated in time (to do enucleation), when cells spread to the intracranial torsion, eye foreign or distant can be lethal when the organ. Found in the eyes of a small number of purulent (pus vitreous disease) is used.
Yellowish white of the eye
If the white of the eye to turn yellow, then the signal may be something wrong with liver and gallbladder. If the blood out of excessive bile secretion occurs whites yellowing symptoms. This is because the bile is itself a yellow-green fluid secreted by the liver cells being out and stored in the gallbladder, has helped break down the role of excess body fat. When the gallbladder or the liver function of the operation would result in undesirable residual bile plug, making the original should be sent to the liver through the bile duct gallbladder bile leakage from the inflow into the blood, it will produce whites yellowing phenomenon. This is why people who suffer from hepatitis, yellow eyes and skin's sake. If the blood out of excessive bile secretion occurs whites yellowing symptoms.

Red pupil
Eye trauma is common in internal bleeding or certain eye diseases. According to eye the amount of bleeding may have a different shape, vision can have varying degrees of damage.
Pupil-fat blue
Normal with a certain pressure within the eyeball, which maintain the eye of normal blood circulation and metabolism, plays an important role, when the intraocular pressure (eye pressure on the contents of the eyeball wall) is too high glaucoma occurs when the hair spray may be due to corneal edema, and eye in a series of changes have led to the issue of a blue green reflective pupil, glaucoma (also known as glaucoma), or hence the name. Glaucoma patients, the eye becomes like a hard rubber, as they themselves would feel pain Yulie eyes, not quickly seek treatment, there is the risk of blindness.
Exophthalmos
Some people on the move to muster the two eyes of a young age (commonly known as goldfish eyes), which is everyone looks different, not about being sick, but some exophthalmos is a disease. Ocelli prominent, that is the side of the eyeball forward prominent severe can affect the blepharophimosis dysraphism. Side of the eye is about 50% of the outstanding cases of disease caused by the brain, which is the most common brain tumor.
Eyes prominent, the most common cause of hyperthyroidism is. In addition to exophthalmos in patients, but also accompanied by symptoms such as palpitation and thyroid enlargement, and "eyes" in particular bright, "Muguangjiongjiong" and aggressive. In addition, hypertension, Parkinson's disease (Parkinson's disease), leukemia, hemophilia can also be caused by exophthalmos occurred. In addition, a lack of vitamin B vitamin D can cause mild exophthalmos.
Many causes of exophthalmos occurred, in addition to the above mentioned diseases, there is the eye's own reasons, such as high myopia, congenital glaucoma, secondary Qingguang limits and uveitis caused by corneal or scleral staphyloma, etc. These checks will clear through the ophthalmologist.
Both sides of the pupil size ranged from
Common in stroke, cerebral thrombosis, brain tumors, etc.; mydriasis, more common in traumatic brain injury, cerebrovascular disease, severe of Japanese encephalitis, purulent meningitis, etc.; miosis, more common in ethanol (also known as alcohol) poisoning , sleeping pills poisoning and the elderly pontine tumors, pontine hemorrhage, also seen in diabetes mellitus (due to the pupil by the autonomic vasomotor regulation, which lead to diabetes, autonomic damage, can affect the pupils of the systolic and diastolic function, clinical findings, diabetic smaller than normal pupil). In addition, organophosphate poisoning, can occur miosis, morphine poisoning can occur when the needle-like pupil. So vastly different size of the pupil or the pupil is not circular: the nuclear envelope is commonly found in the spinal cord and cerebrospinal syphilis. In an open area, should be "STDs," screening, timely diagnosis and treatment can also be recovered.
Eyelid whiten: Be careful anemia
If the blood vessels on the eyes, mucous membrane color too shallow and almost invisible to the case, it may mean anemia. Women due to special physiological period, more prone to symptoms of anemia. So, you had better turn often mirror his own eyelids carefully check something. In addition, it may help dizziness when standing up, a little movement palpitations, asthma kept the skin dry and dull, off the hair, nails become fragile to determine whether symptoms such as anemia.
Eyelid edema: poor water metabolism
Even before going to bed, and do not drink a lot of water, the morning some people had found itself with baggy eyes. This situation is the function of the body's water regulation is not working results. Metabolism disorders caused by water for many reasons, such as reduced kidney function, or gastrointestinal function and cardiac disease. In the end, where is the problem, you need to carry out a comprehensive systemic symptoms judge. If the eyelid edema, and fatigue, dry mouth, voiding difficulty, there may be kidney failure
