Conjunctivitis is a disease caused by a series of inflammatory reactions in the tissues of the conjunctiva that are affected by certain factors and is more common in daily life. Although it does not usually cause adverse effects on body functions, complications caused by it can lead to blindness and therefore require active treatment. Conjunctivitis is still mostly an infection, mainly bacterial, viral, and fungal, and the main focus is on bacteria, so the main method of treatment for conjunctivitis is still to fight bacterial infection. At present, the main drug treatment is still based on eye drops, which are mainly anti-bacterial drops (tobramycin eye drops and ofloxacin eye drops), but the safety of the drug for under 1 year old is not clear. Because each patient’s specific situation is different, such as age and size is different, there is no history of drug allergy, there is no drug resistance, there is no other underlying systemic diseases affecting the use of drugs, and now in the primary hospital antibiotics are still a large number of abuse, resulting in resistance to most drugs, so it is recommended that you can not use drugs indiscriminately, only through a professional doctor to assess the specific situation of each person, and then detailed drug The treatment.
