Definition of pink eye: The common name “pink eye” is infectious conjunctivitis, also known as fulminant fire eye, is an acute infectious ophthalmia. According to the different causes, can be divided into bacterial conjunctivitis and viral conjunctivitis two types, its clinical symptoms are similar, but the prevalence and harm to viral conjunctivitis is heavy. The disease can occur throughout the year and is more common in the spring and summer months. Red eye is an eye disease that is transmitted by contact, such as contact with towels, washing utensils, faucets, door handles, swimming pool water, and common toys used by patients. Therefore, the disease often spreads widely in kindergartens, schools, hospitals, factories and other collective units, causing outbreaks and epidemics. In the early stages of the disease, patients feel hot, burning, photophobic, red eyes, self-conscious eye pain, like entering the sand rolling pain, followed by red eyelids, eye mucus, fear of light, tearing, morning when you get up, the eyelids are often stuck by the secretions, not easy to open. In some patients, small bleeding spots or hemorrhagic spots appear on the conjunctiva, the discharge is mucopurulent, sometimes a layer of gray-white pseudomembrane forms on the surface of the lid conjunctiva, and there can be gray-white infiltrating spots on the edge of the cornea. If a large amount of mucopurulent secretion adheres to the corneal surface, there may be temporary blurred vision or iris (rainbow-like aperture in front of the eyes), and once the secretion is wiped away, the vision can be clear. If a bacterial or viral infection affects the cornea, photophobia, tearing, and pain are aggravated, and there is a degree of vision loss. The onset of red eye is rapid, usually starting within 1 to 2 days of infection with bacteria, and most of the disease develops in both eyes. The disease is highly contagious, because the immunity is low after the cure, so the infection can be repeated (such as re-exposure to the patient can also get sick), from a few months of infants to 80 or 90 years old may develop. The epidemic is fast, after suffering from pink eye, often one person gets the disease, and within 1 to 2 weeks it causes widespread spread throughout the family, kindergartens, schools, factories, etc., regardless of sex, age, and a large number of patients are infected. Attention red-eye is a very contagious eye disease, therefore, the prevention of red-eye is also the same as the prevention of other infectious diseases, must seize the elimination of the source of infection, cut off the transmission route and improve the body resistance to three links. Actively treat red-eye patients with appropriate isolation. During the treatment of red eye, avoid contact with the patient and his or her used objects, such as washcloths and washbasins, as much as possible. Try not to go to public places (e.g., swimming pools, theaters, stores, etc.). Pay attention to disinfection and isolation (boiling and disinfection) of personal items (e.g. towels, handkerchiefs, etc.) or common items in kindergartens, schools, barbershops, bathrooms, etc. Individuals should be careful not to rub their eyes with dirty hands, cut their nails regularly, and wash their hands before and after meals. Apply antibiotics or antiviral eye drops to the eyes when possible. You should open the affected eye, not cover it, because if you cover it, the eye secretions cannot be discharged, and the local temperature and humidity of the eye will increase, which will facilitate the reproduction of bacteria or viruses and aggravate the disease. It is advisable to eat a light diet and not to drink alcohol. Treatment After getting red eye, we should actively treat it, and generally require timely, thorough and persistent treatment. Once discovered, treat immediately, do not interrupt, and continue treatment for 1 week even after the symptoms have completely disappeared to prevent a relapse. Treatment can be done by rinsing the eye. When there is a lot of discharge from the affected eye, it is advisable to rinse the conjunctival sac with an appropriate rinse agent such as saline or 2% boric acid water 2 to 3 times a day and wipe the lid margin with a sterile cotton swab. Eye drops or ointment can also be applied to the affected eye. If the infection is bacterial, the most effective antibiotic eye drops can be selected according to the strain of bacteria examined. The secretions need to be scrubbed clean before each dose to improve the efficacy of the treatment. For mixed viral infections of conjunctivitis, in addition to the application of the above drugs, but also available antiviral eye drops, such as adenovirus available 0.1% hydroxybenzazole eye drops, 0.1% peptide butylamine emulsion, such as small viruses available 0.1% herpes net, 0.1% no ring guanosine eye drops, etc., 2 to 3 times a day, if necessary, can also apply interferon. When available, bacterial culture and drug sensitivity tests can be performed to select the appropriate antibiotics. For red eye can also be used in Chinese medicine, Chinese medicine called the disease for the storm wind guest fever or the sky line red eye, generally due to external wind-heat evil poison, so it is appropriate to dispel the wind, heat and detoxification, commonly used diarrhea lung drink and Yin Qiao detoxification pill. When the inflammation is controlled, in order to prevent recurrence, it is still necessary to point eye drops for about 1 week, or apply astringent, such as 0.25% zinc sulfate eye drops, 2 to 3 times a day, in order to improve the state of congestion and prevent recurrence.
