Infectious conjunctivitis, commonly known as pink eye, is an acute infectious ophthalmia. Depending on the causative agent, it can be divided into two categories: bacterial conjunctivitis and viral conjunctivitis, which have very similar clinical symptoms. How to treat pink eye? Keep your eyes clean. Since there is a lot of discharge from the eye when you have acute conjunctivitis, relying solely on medication is not an option. It is important to carefully care for the eye often to keep it clean, using sterile physiological saline or 3% boric acid solution to wash the eye or eye bath, and then drops into the eye solution to give full play to its drug effect. Apply cold compresses initially and use hormonal eye drops with caution. Acute conjunctivitis at the beginning of the eye should be cold compresses, to help reduce swelling and redness. On the contrary, hot compresses will make the eye congested, inflammation may spread and aggravate the condition. When the inflammation is not controlled, hormonal eye drops are contraindicated, especially in viral conjunctivitis. Therefore, the use of hormonal eye drops should follow the medical advice of the ophthalmologist. Use antibiotic eye medications. Antibiotics are more effective for bacterial conjunctivitis, and although they are not effective for viral conjunctivitis, they are useful for preventing bacterial infection. Commonly used are tobramycin eye solution, 0.25% chloramphenicol eye solution, and erythromycin or tetracycline eye ointment. Viral conjunctivitis can also be treated with morpholine guanidine hydrochloride ophthalmic solution, cyclocytosine or iodoside drops, and various antiviral neutralizing ophthalmic solutions. Avoid light and heat and use the eye sparingly. In patients with severe acute conjunctivitis who are photophobic and tearful, avoid light and heat stimulation in order to reduce discomfort. Do not force yourself to read or watch TV, and wear sunglasses when you go out to avoid stimulation by ultraviolet light and sand. In order to make the discharge of eye secretions smooth, reduce the local temperature, and not conducive to the growth of germs, the eye should not be wrapped or wear an eye patch. Treatment of pink eye must follow medical advice on medication. Eye drops are generally administered every 1-2 hours, 1-2 drops per eye, because the effect of eye drops generally lasts 30 minutes, and drops are too frequent or too sparse to be appropriate. Before going to bed, sterile cotton swabs can be used to gently remove the secretions and then apply eye ointment, which can also prevent conjunctival secretions from adhering to the conjunctival sac. Both eye solution and eye ointment should be used exclusively to avoid cross-infection or transmission of eye disease. Second, the red eye precautions 1, pay attention to hand hygiene. To develop the good habit of hand washing, less eye rubbing, do not rub your eyes with dirty hands, to cut nails. 2, often use public supplies (such as computer keyboards, telephones, door handles, etc.) people, do not rub your eyes during use, and should remember to wash your hands after use. 3.If red-eye is found, it should be isolated in time to control the source of infection. Patients with towels, handkerchiefs, basins, glasses and other personal items and healthy people are used separately, preferably often disinfected, washed, natural sunlight, sun-dried patients and then used, preferably to do “exclusive use” to avoid cross-infection. 4, children’s resistance is weak, as little as possible to go to crowded places, and to maintain hand and eye hygiene, and less contact with sick family members. 5, after getting red eye to actively treat the symptoms completely disappeared, but still continue to treat a week, during the treatment is not interrupted to prevent recurrence. In addition, should also be less to public places. 6, healthy people can point antibiotic eye solution to prevent. Wash your face preferably with flowing water, basin, towels and other utensils should be disinfected. People who have suffered from epidemic acute conjunctivitis are not immune to this disease and also need to pay attention to prevent reinfection. 7, in the red-eye high incidence of summer, before and after swimming can be appropriate drops of anti-inflammatory eye drops, to play a preventive role. 8, during the red eye infection, do not wear corneal contact lenses.
