Trachoma is mostly related to poor hygiene, malnutrition and other factors, and can be transmitted through contact, mother and child, insects, etc. The easiest way to determine trachoma is to judge from the patient’s performance of symptoms, and trachoma is divided into the acute stage and the chronic stage. 1. Acute phase: patients will experience redness and pain in the eyes during the acute phase, and there will be tearing or purulent secretion, and the lymph nodes in front of the ear will be enlarged in some patients, and conjunctival congestion will also occur in some patients. 2. Chronic stage: In the chronic stage, the above symptoms will be reduced, and may be accompanied by papillary hyperplasia of the conjunctiva, follicle formation, scar formation and other changes. Patients usually can’t judge by themselves, when there is redness in the eyes, foreign body sensation and other discomforts, they should go to the hospital in time for medical treatment, and under the guidance of the doctor for treatment after confirmation of the diagnosis.
