What are the manifestations of keratitis? What is the cause? How can it be prevented and treated?

Keratitis is commonly known as "black eye inflammation", which is manifested as eye redness, eye pain, photophobia, tearing, foreign body sensation, blurred vision, and white black eyes. It is one of the common blinding eye diseases. It not only causes pain to the patient, but also seriously affects the appearance.

Keratitis is common**:

1. Infection: In China, keratitis blindness caused by infection ranks first, mostly viruses, bacteria, fungi, Acanthamoeba and so on. It is often caused by fatigue, corneal foreign bodies, tree branch scratches, corneal contact lenses, etc.

2. Trauma: Various traumas cause corneal tissue structure damage resulting in keratitis, such as corneal contusion, penetrating injury, cataract, glass cut and other intraocular surgeries that damage the cornea, so that the corneal endothelium is decompensated. Acid-alkalin, thermal burns of the eye lead to destruction of ocular surface structure.

3. Systemic diseases: rheumatoid, diabetes, dry eye syndrome, nervous system diseases and other eye diseases affect or cause corneal lesions.

Severe keratitis such as Pseudomonas aeruginosa infection is very dangerous, Pseudomonas aeruginosa mostly exists in soil and water, once infected, often within 24 hours or 48 hours to destroy the entire cornea and lose the whole eyeball, and fungal infection is more common in eye trauma, especially after being damaged by crops, but also seen in nail digging and other nature of keratitis secondary fungal infection, therefore, in addition to paying attention to eye personal hygiene in daily life, we should also pay attention to labor protection, once there is eye trauma, it is necessary to go to the hospital immediately, handled by professionals. Also, do not use unclean eye drops.

Keratitis**:

Emphasizing that early diagnosis is very important, and the poor effect of keratitis is often due to unclear diagnosis. If it is a viral infection, no matter how much antibiotics are used, it will not be effective. Corneal transplantation is an effective procedure to save the eyeball** for patients who do not respond to medications** or who have serious complications such as perforated corneal ulcers, prolapsed eye contents, or secondary glaucoma.

Keratitis is divided into two categories: ulcerative keratitis (corneal ulcer) and non-ulcerative keratitis (deep keratitis). It is caused by different factors such as internal and external factors. Corneal trauma is an inflammation caused by bacteria and viruses invading the cornea.

The affected eye has a foreign body sensation, stinging or even a burning sensation. Mixed hyperemia on the bulbar conjunctival surface with symptoms such as photophobia, lacrimation, visual disturbances, and increased discharge.

Causes of keratitis:

1. Physical reasons can lead to keratitis, from some systemic endogenous diseases, corneal tissue participates in the immune response of the whole body, although the degree of its immune response is relatively low, but because it has no blood vessels, so the metabolism is relatively slow, so this immune response changes will last for a long time, and the cornea will be in this sensitive state for a long time, so it is easy to lead to keratitis. For example, suffering from diseases such as vesicular keratitis and so on;

2. The cells of the corneal epithelium are damaged and shed off, which will also lead to keratitis, and infection will also occur, and when both conditions are met, infectious keratitis ulceration will occur.

Ways to prevent and ** keratitis:

First of all, you should ensure that your eyes are well rested.

Second, eat a reasonable diet. People with keratitis should eat more vegetables and fruits rich in vitamins and fiber. Eat more high-calorie, high-protein foods such as beans, soy products, lean meat, and eggs to repair the cornea.

You should stop smoking and drinking, and avoid foods that are fried, spicy, fatty and high in sugar. Mental recuperation is very important in this disease, and it is most important to avoid depression and anger, so as not to aggravate liver fire, which is not good. But it is also not advisable to talk and laugh excessively, and take a comfortable and quiet mood as the degree.

Finally, a healthy lifestyle should be adopted. Because patients with herpes simplex keratitis are toxic for life, any factor that affects immune fluctuations can trigger old diseases**. Patients should live a regular life and avoid staying up late, drinking, overeating, colds and fevers, sun exposure and other triggers to reduce the risk of old diseases**.

Once the old disease is abiding, it is necessary to go to the hospital in time to receive the doctor's diagnosis and consultation and consultation, and do not use drugs indiscriminately, so as not to complicate the condition and increase the difficulty of the disease.

In addition, people with keratitis should also eat more foods that contain vitamin C. Vitamin C is one of the components of the vitreous humor of the eyeball, and once the lack of vitamin C in the diet can easily cause vitreous opacity and cataracts. Foods rich in vitamin C include a variety of fresh vegetables and fruits, especially green peppers, cucumbers, cauliflower, bok choy, fresh dates, raw pears and oranges.

**。The common ** mainly includes infectious, endogenous, local spread, etc.

Infectious-originated. It is the most common cause of keratitis, and pathogenic microorganisms include bacteria (such as pneumococcus, Staphylococcus aureus, hemolytic streptococcus, Pseudomonas aeruginosa, gonorrhoea, etc.), viruses (herpes simplex virus, adenovirus, etc.), fungi, Acanthamoeba protozoa, mycoplasma, chlamydia, Treponema pallidum, etc.

It usually occurs when corneal epithelial cells are damaged, shedding, or weakened immunity. Injury to the corneal epithelium is highly susceptible to infectious inflammation. Therefore, corneal foreign bodies, corneal abrasions, incorrect use of contact lenses, and ocular contact with contaminated drugs or water sources are common susceptibility factors for infectious keratitis, and patients with diabetes, malnutrition, and chronic wasting diseases are also susceptible to keratitis due to decreased resistance.

Endogenous. Refers to an intrinsic disease that originates from the whole body. Some autoimmune diseases, such as rheumatoid arthritis, can cause corneal lesions, or other systemic disorders (eg, vitamin A deficiency, trigeminal nerve damage) that affect the cornea, causing corneal dryness or corneromalacia.

Locally spreading.

Inflammation of adjacent tissues can spread to the cornea, such as conjunctivitis (causing infiltrative inflammation of the peripheral cornea), scleritis (which can lead to sclerosing keratitis), and iridocyclitis (which affects the corneal endothelium).

This keratitis caused by hygiene reasons needs to be seen in the hospital.

The eyes are an indispensable and vital organ for us, but if we don't pay attention to them in life, we can suffer from a variety of eye diseases. From the current situation, among the many ophthalmic diseases, keratitis is more common. Keratitis, once it develops, not only affects vision, but can sometimes lead to blindness.

Many patients report that they suffer from keratitis and are in pain. So how should we regulate our daily life after getting keratitis?

1.Rinse. If the discharge is high, the conjunctival sac can be flushed with saline 3 or more times a day to flush out the secretions, necrotic tissue, bacteria, and toxins produced by bacteria. In this way, not only the factors of infection propagation are reduced, but also the concentration of the topical drug can be ensured.

2.Eat more foods that contain vitamin C.

Because vitamin C is one of the components that make up the lens of the eyeball. If you are deficient in vitamin C, you are susceptible to cataract disease with cloudy crystals. What is good to eat if you have keratitis, vitamin C-rich foods have a variety of fresh vegetables and fruits, what is good to eat when you have keratitis, especially green peppers, cucumbers, cauliflower, cabbage, fresh dates, raw pears, oranges, etc.

3.Avoid alcohol and mutton. Alcohol can reduce the body's immunity and speed up the reproduction of the virus, so patients with viral keratitis must quit drinking and alcoholic beverages Because the deep corneal lesions of patients with viral keratitis are manifestations of immune response, and eating mutton can aggravate this chronic immune reaction, resulting in aggravation of the disease, so patients with viral keratitis should not eat mutton.

4.Change your eye habits.

If the eye habits are not corrected, on the one hand, keratitis will be relatively slow, and on the other hand, it will lead to frequent keratitis. Therefore, cultivate the habit of cleanliness and hygiene, do not wipe your eyes with dirty hands and handkerchiefs, and regularly boil and disinfect your face utensils to prevent repeated infections, aggravate the pain, and cause adverse consequences.

Actively cause the primary disease of keratitis, pay attention to maintain eye hygiene, do not overuse your eyes, do not overwork, and exercise appropriately to enhance resistance. Do a good job of monitoring the condition and actively cooperate**.

Family members should give psychological comfort in a timely manner to help them build confidence and make the patient actively cooperate**.

Adjust your diet, don't eat some spicy food, pay attention to cleanliness and hygiene, be sure to check on time, pay attention to anti-inflammatory work, and take medications on time.

Don't stay up late, don't eat greasy things, don't eat raw and cold things, don't often stare at the electronic screen, you can drop some eye drops to recuperate.

1. Epithelial exfoliation caused by long-term dry eye syndrome, which is also a superficial punctate keratitis; 2. Immune, such as allergies, can also cause keratitis; 3. Keratitis caused by fungal implantation in the eye, called fungal keratitis, is the most dangerous kind of keratitis; 4. Keratitis caused by bacteria is called bacterial keratitis; 5. Keratitis caused by the virus entering the eye is called viral keratitis, which is easy to reverse. No matter what kind of keratitis is above, once it appears, you must go to the hospital in time.

Exogenous ** infection is the most common cause of keratitis, mainly due to corneal epithelial cell damage, detachment and co-infection, common pathogens include bacteria, viruses, fungi, chlamydia and so on.

Most of them are caused by unhygienic eyes, keratitis should be timely**, pay attention to let the eyes rest, do not wipe the eyes with dirty hands.

Corneal inflammation is generally caused by improper eye hygiene or heat dissipation, so at this time, you must find a professional doctor to check **, so as to be more conducive to the effective recovery of health.

The main thing is that the eyes are infected, and it may lead to keratitis when you touch the eyes with hand, or shampoo, facial cleanser and other things. Be sure to see a doctor promptly.
