Prevention and treatment of keratitis and keratopathy and dietotherapy

cornea is an important refractive stroma. It is colorless, transparent and rich in nerves. The metabolism of the cornea itself is not vigorous. Therefore, the healing of the lesion is slow and takes a long time. Once it is damaged, it feels very sensitive. Although it is a small wound or foreign body, it will cause obvious pain and tears, fear of light and can’t open your eyes. The cornea is like the lens of a camera.

in corneal lesions, keratitis accounts for the first. There are many causes, including bacteria, viruses, molds, trauma, autoimmune diseases, nutritional disorders and so on. Clinical symptoms of

and

: from the beginning, there is only a sense of foreign body friction in the eyes, occasionally tingling or burning, redness, fear of light, tears, inability to open the eyes, and conjunctival edema in severe cases; At the site of corneal epithelial damage, gray white or yellowish white infiltration points first appeared. The surface is slightly uplifted, with diffuse edema and turbidity around and corneal discomfort. You must go to the hospital in time to avoid corneal necrosis, ulcer perforation and blindness.

what should patients with corneal ulcer pay attention to?

and

first relax, build confidence and take medicine on time. Pay attention to eating light, nutritious and digestible food. Eat less fried food. More vitamin B 1, B2, C, a food. Vitamin B1 is an important nutrient for maintaining the integrity of optic nerve tissue. Vitamin B2 can enhance the respiration of corneal epidermal cells, improve local material metabolism and prevent the formation of neovascularization. Vitamin A can enhance human immune function and the health of corneal tissue. Vitamins play an important role in regulating human physiological functions. Once vitamins and trace elements are lacking, there will be obstacles in material metabolism in the body, resulting in disorder of human physiological function. However, vitamins needed by the human body cannot be synthesized in the body and must rely on food supply.

and

fresh fruits and vegetables contain a lot of vitamin C and vitamin A. animal foods with high vitamin a content include: animal liver, in which chicken liver contains the highest vitamin. In addition to rich vitamin A, liver also contains other important nutrients, which can maintain the comprehensive balance of nutrients; Vitamin A in egg foods is concentrated in egg yolk; Fish: crucian carp, Monopterus albus, silver carp and small yellow croaker contain more vitamins; Milk, especially human milk, is rich in vitamin A, followed by milk and goat’s milk. Infants eat mother’s milk, which is the most nutritious. Because most of vitamin A is dissolved in oil, the content of skimmed dairy products is very small. The content of whole milk powder and cream is very high. Crustacean food: river crabs, snails, oysters, prawns and sea crabs are high in vitamins. Cod liver oil, butter, butter, butter.

and

plant foods contain vitamins, which are called carotene. They must be chemically decomposed into vitamin A in order to play their nutritional role. The absorption and interest rate of carotene in the body are relatively low. Its nutritional effect is only 1 / 12 to 1 / 6 of vitamin A, but it is very important because we eat it every day. Root foods with high vitamin a content include carrot and sweet potato. The more yellow the meat, the higher the carotene content. Green vegetables contain carotene. The darker the color, the higher the content. Green vegetables are what people eat every day and are the main source of carotene in their diet. Such as winter amaranth, fennel,, celery, kale, mustard, agaric, rape, coriander, spinach and Chinese cabbage. The content of dark yellow cauliflower is high. Yellow fruits such as mango, pumpkin and papaya. Pay attention when cooking. The food must be fresh to prevent the loss of vitamin A; We should match meat and vegetables, learn from each other’s strengths and make up for their weaknesses, so as to make the nutritional components complete; Proper oil must be added, because vitamin A and carotene are fat soluble and can be fully absorbed by the human body only when they are mixed with oil; In the process of cooking, do not take too long and the temperature is too high to avoid the destruction of vitamin A and carotene. Drink more water, avoid alcohol and tobacco, and irritating food.
