In recent years, air pollution is serious, and the number of patients with chronic allergic conjunctivitis has increased sharply. Patients often buy eye drops in pharmacies for their own use. So I took eye drops containing steroids for a long time without knowing it. A few people often use steroid eye drops until their vision and field of vision deteriorate, and only after seeing a doctor do they find themselves with glaucoma. Steroids are widely used in medicine, but if they are used improperly or abused too much, they will easily lead to uncontrollable consequences. The serious consequence to the eyes is to induce glaucoma and cause optic nerve damage. Not all people who receive eye drops containing steroids will get glaucoma, which is generally related to whether the patients themselves belong to the "steroid allergy group".
Long-term treatment of chronic conjunctivitis patients, if there is eye swelling or blurred vision, doctors should be reminded to measure intraocular pressure to determine whether glaucoma has been induced. In summer, the epidemic of acute conjunctivitis is bound to reappear, and steroid eye drops will be used for extensive treatment. This kind of situation should be carefully guarded against. Ophthalmologists should be carefully selected and medication should be adjusted according to the condition to avoid serious sequelae caused by long-term ordering of steroid eye drops.
Chronic conjunctivitis plagues many patients with eye diseases. Due to the repeated stimulation and inflammation of the conjunctiva, the surface of the conjunctiva will be uneven and even form stones or scars. Once these lesions are formed, it is difficult to restore to the original smooth surface, which is one of the reasons why the symptoms cannot be cured. Therefore, the treatment of chronic conjunctivitis is symptomatic and retreatment in principle. If there is no discomfort, but there are traces of past inflammation on the conjunctiva, eye drops are not necessary for maintenance, because the tears in the eyes are the best moisturizing maintenance solution.
Causes of conjunctivitis:
1. Bacterial or viral infection cannot be completely cured.
2. Repeated external stimuli, such as wind, smoke and flying dust.
3. Eyelid problems, such as inverted eyelashes always irritate eyes, or ectropion of eyelids exposes conjunctiva to air for a long time, resulting in dryness and redness.
4 dacryocystitis and inflammation of skin around eyes
5. Dry eye can't effectively moisten eyes due to the decrease of tear secretion, and it is sensitive to external environmental stimuli.
6. Long-term eye drops, because there is a reaction to the ingredients or preservatives in eye drops.
Conjunctivitis symptoms:
1. Eyes reddish
2. Dry and tired
3. Itching and uncomfortable.
4. There is not much secretion, and occasionally there is chewing gum.
5. Blink frequently, shed tears or shed tears less.
Easy fatigue
Treatment:
1. The main thing is to find out the cause and prescribe the right medicine. If infected by pathogenic bacteria, the treatment is ineffective, and effective drugs can only be given after the pathogenic bacteria are detected.
2. If it is caused by external environment, you should try to avoid contact with stimulus sources. Going out less can reduce wind blowing and contact with oil, smoke and dust.
3. Eyelid problems, such as trichiasis and ectropion, need to be considered for surgical treatment.
4. Remove eyelid margin secretion, apply hot compress, wash eyelashes, apply ointment and take antibiotics orally.
5. Dry eye, don't use artificial tears without preservatives.
6. Long-term eye drops should be stopped first.
Red eye
Acute keratoconjunctivitis is highly contagious. Most people mistakenly think that it will be contagious only one or two days ago, but it will be contagious within two weeks. The main clinical symptoms are intraocular foreign body sensation, eyelid edema, sexual light, tears and some sticky secretions; The patient has an attack in one eye and then spreads to the other eye, or both eyes have an attack at the same time. Usually it is often accompanied by swollen lymph glands in front of the ear, and there will be a slight feeling of discomfort. If the child is infected, there will be obvious systemic symptoms, especially when there is a baby at home. Pay special attention, because the baby's own immune system is not perfect. When you are infected with acute infectious keratoconjunctivitis, the symptoms will be more serious, except for fever and swollen lymph glands.
About 50% patients with acute keratoconjunctivitis may have corneal complications (superficial punctate keratitis). Because acute keratoconjunctivitis not only invades the conjunctiva, but also invades the cornea, causing some punctate inflammation of the cornea and forming "subepidermal turbidity". If it is close to the pupil, it will affect vision, blur vision, and even cause corneal ulcer, which will aggravate the condition. If not treated in time, it will be infected by bacteria, which will not only seriously harm vision, but even lead to blindness. This disease is prevalent in spring and summer, mainly caused by virus infection. If your family suffers from this disease, you should use a bathroom set alone to avoid infection. Wash your hands at all times during the epidemic and avoid contact with your eyes. Acute conjunctivitis often damages the conjunctival surface skin, and it is normal to feel pain when taking medicine. Please don't stop taking medicine because of pain. If there is a white membrane covering the conjunctiva surface, that is, a false membrane, it must be scraped off as soon as possible to avoid leaving scars and sequelae in the future.
Epidemic conjunctivitis
Causes of epidemic conjunctivitis: mainly adenovirus infection.
Transmission path:
1. Hands of medical staff
2. Ophthalmic examination instruments (such as tonometer, slit lamp) or eye potions (such as washing liquid and local anesthetic), among which hand-borne infection by medical staff is the most important cause of mass emergencies.
3. Contact infection is highly contagious, and one person often infects the whole family.
According to many foreign documents, it is known that the outbreak of epidemic conjunctivitis mostly occurs in outpatient departments of ophthalmology and hospitals. The survey results show that the pollution of eye chemicals, improper instruments and equipment for eye disinfection and inspection, and the source of hand-borne infection by medical staff are all the reasons for these outbreaks.
Symptoms: red eyes, foreign body sensation, increased yellow secretion, sticky eyelashes, swollen lymph glands, fever and other systemic symptoms.
Treatment method:
1. Due to the ever-changing virus, there is no specific medicine at present, and the treatment method is mainly symptomatic treatment.
2. Please wear gloves when checking or nursing patients suspected of having epidemic conjunctivitis.
3. Wash your hands with hand sanitizer containing disinfectant after inspection or nursing.
4. Patients should avoid sharing eye drops with other patients.
5. All instruments that come into contact with conjunctiva should be disinfected or highly disinfected.
6. After use, each patient should wash the intraocular pressure head with clean water, soak it in disinfectants such as 500ppm chlorine, 3% hydrogen peroxide, 70% ethanol or 70% isopropanol for five to ten minutes, rinse it with sterile distilled water, and finally take it out and dry it for the next patient.
7. Strengthening hand washing and paying attention to personal hygiene habits are the simplest and most effective ways to prevent nosocomial infection of epidemic conjunctivitis.
What is the reason why there is a white nebula in cornea and conjunctiva? Talking about blindness
Blindness, also known as puffiness, mostly occurs in middle-aged and elderly people, mostly outdoor workers. Bulbs are pathological hyperplasia of conjunctival tissue after long-term stimulation, including ultraviolet rays in sunlight. Most nebulae grow near the nose of the white eyeball, slowly extending to the transparent cornea in front of the black eyeball, and a few grow near the temporal side of the white eyeball, which is also the direction of the cornea. At the beginning, eyeball-like hypertrophy has little effect on vision, but if it is allowed to grow, it will cover the whole pupil when it reaches the center of cornea, which will seriously affect vision. Moreover, the longer and bigger the eyeball, the deeper the infringement on the cornea will be. Even if the eyeball is removed, it will leave a scar on the cornea, and it will still be unclear. therapeutic method
1. Because the soft tissue is covered with blood vessels, as long as the eyes are tired or inflamed, the parts of the eyes will be particularly red and swollen, and eye drops or ointment can be used locally to diminish inflammation.
2. If the conjunctiva is too big to cover the pupil and hinder vision, or the conjunctiva is thickened and the white and red meat slices are not good-looking, they can be surgically removed.
3. However, the conjunctiva is extremely energetic. If only resection is performed, the recurrence rate is as high as 50%. Fortunately, the growth of sclera can be effectively inhibited by special eye drops made of anticancer drugs or radiation irradiation on the surface of sclera after operation, and the recurrence rate can be reduced to about 10%. Even so, 2% to 5% of cases will recur.
prevent
There is no effective prevention method so far, but it is helpful to pay attention to the following four points at ordinary times.
1. Protect your eyes from excessive ultraviolet radiation. For example, 10:00 am to 2:00 am to avoid outdoor activities. If you must go out, you may wish to cover your eyes with a sunshade, hat or sunglasses.
2. Avoid dry heat, dusty and windy environment.
Because of professional needs, if you have to work in the hot sun, you'd better wear sunglasses. On the one hand, it can reduce the occurrence of blindness, on the other hand, it can avoid the occurrence of cataracts.
conclusion
Black eyes, that is, the position of the cornea, are equivalent to the first lens of the camera lens. If there is fat, it will directly affect vision. Therefore, when the cornea appears fat, it must be diagnosed and treated as soon as possible, so as not to cause scars that can never be erased.
Red eye disease and its prevention
Commonly known as "pink eye" is infectious conjunctivitis, also known as fire eye outbreak, which is an acute infectious ophthalmia. According to different pathogenic reasons, it can be divided into bacterial conjunctivitis and viral conjunctivitis. Their clinical symptoms are similar, but viral conjunctivitis is the most popular and harmful. This disease can occur all year round, especially in spring and summer. Pink eye disease is an eye disease spread by contact, such as contact with towels, washing utensils, faucets, door handles, swimming pool water, public toys and so on. Therefore, the disease often spreads widely in kindergartens, schools, hospitals, factories and other collective units, leading to outbreaks.
Pink eye disease is acute, highly contagious and spreads quickly. After suffering from pink eye disease, a person often gets sick, which causes widespread spread in the whole family, kindergarten, school and factory within 1-2 weeks. A large number of patients, regardless of gender, age and age, are infected.
Pink eye disease is a highly contagious eye disease. Therefore, to prevent pinkeye, just like other infectious diseases, we must seize three links: eliminating the source of infection, cutting off the route of transmission and improving the body's resistance, actively treat pinkeye patients and isolate them appropriately. In the process of treating pink eye, try to avoid contact with patients and their used items, such as washing towels and washbasins. Try not to go to public places (such as swimming pools, theaters, shops, etc.). ). Personal articles (such as towels) or public articles such as kindergartens, schools, barbershops and bathrooms should be disinfected and isolated (boiled and disinfected). Individuals should be careful not to rub their eyes with dirty hands, cut their nails frequently, and wash their hands before and after meals. Use antibiotics or antiviral eye drops when conditions permit.
The affected eye should be opened, but it can't be covered, because after covering the affected eye, the eye secretions can't be discharged, and the local temperature and humidity of the eye increase, which is beneficial to the reproduction of bacteria or viruses and aggravates the condition.
It is advisable to have a light diet, but it is best not to drink alcohol.
Discussion on the treatment of chronic conjunctivitis
Some people are jealous for a long time, sometimes light and sometimes heavy, probably because of chronic conjunctivitis. Chronic conjunctivitis is a common and frequently-occurring disease, often bilateral and sometimes very stubborn, which cannot be cured after long-term treatment. The main symptoms of chronic conjunctivitis are ocular secretions and conjunctival congestion. The patients have mild symptoms, mainly itching, burning sensation, foreign body sensation, dryness, heavy eyelids and visual fatigue. Generally, symptoms are obvious when working at night or at close range, but some people feel uncomfortable.
The pathogenic factors of chronic conjunctivitis mainly include the following points:
1: Due to untreated or incomplete treatment of acute conjunctivitis, the infection factor turned chronic.
2. Stimulating factors are the most common reasons. Such as harsh living or working environment, polluted air, sandstorm, smoke, strong light,
Insufficient light, harmful gases, excessive drinking and lack of sleep, water pollution during swimming and other diseases.
Stimulation.
3. Drug irritation caused by long-term use of some eye drops such as adrenaline, mydriatic drugs and some irritating eye drops.
The treatment of chronic conjunctivitis should focus on removing the etiology, aiming at the symptoms and aiming at the bacteria. Zhengda Vita eye drops produced by Zheng Da Freda Pharmaceutical Co., Ltd. treat chronic conjunctivitis through anti-inflammatory and astringent effects. Zhengda Vita contains natural moisturizing thickener, which can slowly release active drugs with long-lasting effect, obviously improve the microcirculation of inflammatory parts, accelerate the repair of eye tissues, moisten and nourish cornea and improve eye symptoms. Because Zheng Dawei himself does not have strong antibacterial ability, patients with chronic conjunctivitis caused by bacterial infection should be treated with Runshu eye drops first. For those patients who have used a variety of antibiotics and antiviral drugs but still failed, Zheng Dawei will receive unexpected therapeutic effects.
