We often say that the eyes are the windows to the soul.

Eyes are an important medium for expressing our emotions, our joys and sorrows, our thoughts can often be conveyed through a look.

At the same time, lesions in some of our body's vital organs are expressed through the eyes, and experienced clinicians are able to catch unusual signals from the organism through the patient's eyes.

As ordinary people, we can also detect early lesions in the internal organs of the body through some changes that occur in the eyes.

I'm going to summarize for you today what organs of the body we can tell are in trouble from the eyes.

First of all, let's recognize the structure of the eye, so that we can understand it better in the next step

Remember these important structures

Pupil: This is the black eye in the center of our eye, it is the channel through which light enters our eye, it can be large or small, and is responsible for regulating the amount of light entering the eye. Normally, the pupil opens wide when the light is dim, and it narrows when the light is bright.

Sclera: porcelain white, usually referred to as the whites of the eyes

Cornea: transparent membrane, acts as a refractor

Conjunctiva: a thin, transparent mucous membrane rich in blood vessels that covers the inner surface of the eyelid and the front of the eye.

Eyelids: eyelids

Let's start with the eyelids.

I. Eyelids (eyelids)

We know that our normal human eyelids can open and close at will. But if the function of eyelids closing and opening at will is impaired, then there may be something wrong with our nerves and brain.

1. Droopy eyelids, can't open eyes

If it's bilateral, it suggests possible myasthenia gravis, but also congenital ptosis

If it is unilateral, it suggests that the arterio-ocular nerve, which innervates eye movement and eyelid elevation, has been damaged, which is mainly seen in car accident trauma, encephalitis, cerebral hemorrhage, and brain abscess.

(Eyelids drooping, can't open eyes)

2. Eyelids don't close

The inability to close both eyes may be due to hyperthyroidism. In hyperthyroidism, the eyes protrude, causing the eyelids to fail to close

(Hyperthyroid patient's eyes open angrily, eyelids don't close)

Failure to close the eyelid unilaterally may be due to damage to the facial nerve, which controls eyelid closure and is most often seen in facial paralysis.

3. Frequent fluttering of the eyelids

As the saying goes, the left eye jumps to wealth, the right eye jumps to disaster. In fact, in fact, if the frequent eyelid jumping is a manifestation of facial muscle spasm. The cause of this disease is often caused by a tumor in the skull that irritates the nerves, or by small blood vessels in the skull that compress the nerves. It needs to be treated with medication and surgery.

4. Eyelid edema

This was mentioned in one of my earlier replies, and if the eyelids are edematous, it is often indicative of problems with kidney function.

2、巩膜

It's our white eyeballs, and because they are white, the eyes are often the easiest to observe if jaundice occurs with a problem in the liver and gallbladder system. Yellowing of the sclera suggests problems with the liver, so beware of hepatitis, stones, and liver cancer.

(Sclera yellowing)

III. Cornea

A yellow or brown ring around the edge of the cornea is suggestive of hepatomegaly. This is an inherited disease with a predominantly cerebral degenerative disorder of cirrhosis and basal ganglia damage caused by impaired copper metabolism.

IV. Conjunctiva

Reddened congestion is common in conjunctivitis

Conjunctival pallor can be seen in anemia

Yellowing of the conjunctiva suggests liver disease

If there is a large subconjunctival hemorrhage, it can be seen in hypertension, arteriosclerosis

(subconjunctival hemorrhage)

V. Recognizing diseases through eye movements

If there is a problem with eye movement, an inability to move to a particular side of theThen it suggests damage to the nerves in the brain, possibly due to a lesion within the brain. For example, cerebral infarction, cerebral hemorrhage, brain tumor or encephalitis

If there is nystagmus, shaking of the eyeballsIt's often indicative of a problem with the ear or cerebellum.

If eye opening and closing decreases, suggesting hyperthyroidism. We normal people constantly and unconsciously close and then open our eyes, which keeps the surface of the eye moist, but this unconscious behavior is greatly reduced in hyperthyroid patients.

VI. Vision loss

If there is a loss of vision, accompanied by vomiting, headaches, andIt's possible there's something wrong with the brain.

If there is a loss of vision, swelling and pain in the eyesI'm not sure if you have glaucoma.

There are many other causes of vision loss, such as myopia, cataracts, retinal detachment, etc., suggesting many conditions. Especially the lesions under the eyes, which we cannot observe by ourselves.

VII. Changes in vision

People have a range to see things, and this range is called the visual field. If there is a defect in the visual field, then beware of retinal detachment, glaucoma, intracerebral tumors and cerebrovascular disease.

VIII. Changes in pupils

We described at the beginning that the pupil regulates the amount of light entering the eye in response to changes in light intensity. It is controlled by the nerves in the skull, and if the brain is damaged, it will show up in the pupils. For example, when a person's brain has been severely damaged, a brain hernia has occurred, and they are dying, the pupils of both eyes will be dilated, which is why the doctor has to examine the eyeballs of a seriously ill person with a flashlight, and if the pupils are dilated and fixed, it means that the condition is already very, very dangerous.

Normally, both pupils should be the same size and rounded.

In glaucoma or intraocular tumors, the pupil becomes oval in shape

(Glaucoma patient, pupil became oval)

Bilateral pupil dilation, possibly pesticide poisoning

Dilated pupils can be a result of damage to the brain nerves, lesions in the brain

If the pupils on both sides are not the same size, there may be a tumor in the brain, neurosyphilis, or traumatic brain injury.

Eye examination is a very important part of medical treatment. Here I will focus on what problems we can see in organs other than the eyes through an eye examination.

First, the examination of eye function, including visual acuity, visual field and color vision and stereopsis. Visual acuity examination can indicate the presence or absence of retinal and optic nerve lesions and the eye's own adjustment ability; visual field defects are commonly caused by lesions of the visual center, optic nerve and retina; color vision abnormalities can be seen in congenital heredity as well as acquired lesions of the retina, optic nerve and posterior bulbous optic nerve.

Second, external ocular examination, including eyelids, tear sac, conjunctiva, and ophthalmoplegia. Bilateral ptosis can be congenital ptosis and myasthenia gravis, and unilateral ptosis is seen in subarachnoid hemorrhage, diphtheria, and encephalitis caused by palsy of the motoneuron. Impaired eyelid closure can be seen in hyperthyroidism and facial nerve palsy. Eyelid edema is common in nephritis and chronic liver disease. Protruding eyeballs can be seen in hyperthyroidism. Spontaneous nystagmus is seen in otogenic vertigo, cerebellar disease and severe vision loss.

Third, examination of the anterior segment of the eye, including the cornea, sclera, iris and pupil. Corneal softening is common in infants and children with malnutrition and vitamin A deficiency. A yellow or tan ring of pigment at the edge of the cornea is called a Kayser-Fleischer ring and is common in hepatomegaly. When jaundice occurs, the sclera is yellow, which is common in hemolytic diseases (e.g., marine anemia, neonatal hemolysis, etc.), hepatocellular diseases (viral hepatitis, cirrhosis), and causes cholestasis, which can also cause jaundice (intrahepatic sedimentary stones, cancerous emboli, and viral hepatitis, etc.). Abnormal pupil size is often indicative of intracranial lesions such as traumatic brain injury and brain tumors.

Fourth, fundus examination. Hypertension, arteriosclerosis, chronic nephritis, diabetes mellitus, and leukemia can all cause changes in the fundus.

The human body is a complex interconnected system because it involves too much specialized knowledge, and much of it is just a little bit of it. Diseases in one organ can cause changes in other organs through blood, nerve and metabolic factors. In medical diagnosis and treatment, no aspect should be taken lightly.

It is said that the eyes are the windows of the soul, in fact, the eyes are also a barometer of people's health, under normal circumstances, the eyes are flexible, bright and energetic is a sign of good health; the eyes are not bright is a sign of deficiency of vitality. The essence of the five organs are injected into the eyes, the eyes and the five organs have a relationship, the liver blood, orifices in the eyes, the kidneys store essence, so the closest relationship with the liver and kidneys:

1, the pupil belongs to the kidneys: the essence of the kidneys to nourish the pupil, if the kidneys are weak, there will be dry eyes, blurred vision, etc., the pupil is not round may be insufficient kidney water.

2、Black eyes belong to the liver: the color of black eyes is gray and white, afraid of seeing light, and the pain of eyebrow bone is mostly liver heat; the color of gray and yellow mixed with white eyes is mostly liver and gallbladder heat.

3, white eyes belong to the lungs: white eyes are filled with blood, mostly because of the heat of the lungs, white eyes are cloudy, mostly because of the lungs are hot, white eyes are yellow, mostly because of jaundice.

4, the eye system belongs to the heart: the inner canthus congestion is mostly heart fire inflammation, the inner canthus red and red is mostly heart meridian fire heat.

5, eye cell is the spleen: eye cell is the upper and lower eyelids, puffy eyelids are spleen deficiency and dampness, drooping eyelids are spleen and stomach qi deficiency, eyelid redness and swelling is spleen and stomach heat, sleep eyelids can not be closed in pediatric slow spleen wind. If the bags under the eyes are dark, it is a sign of insufficient kidney qi.

"What is inside must be outside". Abnormal changes in the eyes are mostly the external manifestations of the abnormal function of internal organs, by observing the changes in the eyes can understand the function of internal organs, looking at the eyes is also an important part of Chinese medicine diagnosis. Therefore, if you find any changes or discomfort in your eyes, you should pay great attention to it, find it in time and treat it as soon as possible so as not to affect your health.

The eyes can be considered one of the most striking facial organs, and from the subtle changes in the eyes, you can observe the clues of physical diseases. In addition to our concern for eye diseases, we can also grasp the secrets of our own health by observing changes in the whites of the eyes, changes in the eyelids, and changes in the eyeballs.

1、Yellowing of the whites of the eyes

The whites of the eyes are actually divided into two layers, the inner layer is called the sclera. If the liver suffers from diseases such as hepatitis and cirrhosis, the sclera will become yellow, or "jaundice". Experts explain that this yellow color is caused by bilirubin, which is produced by the breakdown of hemoglobin.

And the outer layer is called the bulbar conjunctiva, after long-term exposure to ultraviolet rays, dust and other contaminants, it will produce the adverse reaction of pigmentation, the white eyeballs are flushed with dark yellow, the black eyeballs become cloudy, so it is more commonly seen in the elderly.

2. Bleeding in the white of the eye

When you see a reddish color in the white of the eye, it is actually a rupture of a blood vessel in the conjunctiva. However, some people may mistake this for a hemorrhage in the "fundus" of the eye, but this is wrong. It is actually a hemorrhage on the "surface" of the eye, usually caused by a blow or abrasion to the eye.

It is important to be alert to the fact that if bleeding from the whites of the eyes occurs frequently in the absence of an external cause, it may be a manifestation of vascular sclerosis, high blood pressure, diabetes mellitus, or blood disorders such as thrombocytopenia in the eye. However, it can also occur with forceful coughing, habitual constipation or in a few women during menstruation.

3. Droopy eyelids

Droopy eyelids, generally recognized as a sign of aging and a natural phenomenon, naturally occur in older people with loose eyelid skin.

However, ptosis can also be seen in the eyes of patients with myasthenia gravis, brain tumors, stroke, hypertension, and diabetes, but the presentation varies.

(1) If myasthenia gravis has a slow onset, it is light in the morning and heavy in the evening with marked fluctuations throughout the day;

(2) If the disease is caused by diabetes, brain tumor, or stroke, the onset of the disease is rapid, and there are other symptoms such as inflexible eye movements and double vision.

4. Incomplete eyelid closure

Failure to close the eyes, or inability to close the eyelids, also known as "hare's eyes", is actually one of the characteristics of facial nerve palsy and often occurs suddenly.

Inflammation, hemorrhage, and tumors of the cranium and brain can also lead to incomplete lid closure, which needs to be alerted. If it is a child can not completely close the eyelids after going to sleep, or can not be closed tightly, this is a sign of weakness of the spleen and stomach, should pay attention to dietary modification.

5. Crooked eyes

In addition to diseases of the eye itself, most of the eye distortions caused by other systemic diseases, such as tumors, stroke, diabetes, brain tumors, nasopharyngeal carcinoma metastasis, etc., are more urgent, and experienced ophthalmologists will advise patients to go to internal medicine, neurology, or otorhinolaryngology for checkups to rule out related diseases first.

6. Protruding eyeballs

In addition to eye disease, systemic conditions can also cause protruding eyes, and one of the more common noticeable bulges is thyroid disease. The majority of hyperthyroid eye protrusions are bilateral, but they can also occur in one eye. It is important to note that some "hyperthyroid" bulges occur after the thyroid hormones have been brought under control, so they should not be taken lightly. In addition, eye metastases from advanced leukemia can cause eye protrusions called "green tumors".

Life Road public health, Chinese medicine eye dialectic is a very important means of identification ah, looking at the smell and ask for help, looking at an important part of the diagnosis it.

The eye is the orifice of the liver, the heart makes, the eye is the kidney essence of the Tibetan, for the blood of the Zong, the five viscera and six bowels of the essence of the upward injection in the eye.

1. Reddening of the white eyes generally suggests that there is lung heat; yellowing of the white eyes suggests that there is jaundice.

2, redness at the corner of the eyes, suggesting that the heart meridian has fire. The corner of the eye canthus white, suggesting blood deficiency anemia and so on.

3, eyelids have heat red, suggesting that the spleen and stomach have heat. Eyelids black color dark suggests kidney deficiency and water, or cold dampness injection.

4. The eyes are red, indicating that wind-heat is attacking the liver meridian.

5. Protruding eyeballs indicate thyroid disease, or lung swelling.

6, sunken eye sockets suggests that the body fluid loss, blood deficiency, long illness and serious illness.

7. Pupil narrowing suggests organophosphorus poisoning, and pupil dilation suggests critical illness or extreme excitement in adolescents.

As we all know, the eyes are the windows to our soul. In the view of many people, the eyes are used to see the outside world, in addition, there is no other use. But in fact, such a view is too limited, the use of the eyes can be more than this, the use of the eyes also need to be explored and discovered, and sometimes some of the minutiae, can help us to better understand our body. For example, people will have some abnormalities through their eyes, and then go to speculate whether the body where the corresponding health problems. For example, cancer, which is a scary thing to many people, can be detected through changes in the eyes. So, the body has no cancer, day and through the eyes to see it? The body has cancer, eye prophet, 3 kinds of changes in the eyes, maybe it is the tip of cancer.

1. Yellowing of the eyes

Inside the tissue of our eyes there is the white sclera part, the reason why this part is usually white has a lot to do with its own structure. However, sometimes it will turn yellow and with blood, which is related to our body's metabolism, which is related to like to stay up late or often work overtime. However, if the eyeballs have been yellow, and there is no sign of improvement, then we should pay attention, this time may not be ordinary yellow, beware of liver problems, this time should hurry to check to see if the function of the liver has no effect, if so, we need to be treated as soon as possible.

2. Swollen eyes

Some people may have this experience, for example, before going to bed at night, because they drink a little more water, the next morning after waking up will find that their eyes are swollen. This phenomenon is actually quite normal. But if you do not drink more water before going to bed, frequent occurrence of such a situation, then we should pay attention to this time should go to care about their kidneys have no problem, it is best to check the function of the kidneys, if the kidneys have a problem, then you should hurry to treat, so as not to delay the longer, to the body to bring the negative impact.

3. Darkening of the eyes

Often there will be such a person, because the night can not rest properly, so in the daytime, will find their eyes black a whole circle, feel like "pandas", in fact, this is with a certain relationship with the late night, but in addition to staying up late, there is also an important factor, that is, the impact of metabolism. If the metabolism of the liver or kidney metabolism, there is a problem. Therefore, when the circles under the eyes become dark for no reason, it is important to consider whether it is a hint of cancer.
