Three-month-old babies’ eyes with a lot of eye droppings may be caused by physiological reasons, allergic conjunctivitis, tear duct abnormalities and so on, which can be treated by general treatment, medication, surgery and so on. 1. Physiological reasons: when normal babies are 2~3 months old, eye lashes tend to grow inward during this period, and the eyeballs are stimulated by friction to produce eye droppings, which is a normal phenomenon. This is a normal phenomenon. Usually no special treatment is needed, and you can use a warm towel to wipe it off. 2. Allergic conjunctivitis: If your three-month-old baby comes into contact with allergy-prone substances, such as dust mites, house dust, pollen, etc., allergic conjunctivitis may be induced, with symptoms such as excessive eye boogers and redness and swelling of the eyes. In this case, you need to avoid contact with allergens, and if necessary, you can follow the doctor’s instructions to use sodium cromoglycate eye drops, emetine fumarate eye drops and other drugs for treatment. 3. Abnormal tear ducts: three-month-old babies with narrow tear ducts, obstruction and other abnormalities will lead to poor tear flow, easily induced inflammation of the eye surface, which may cause the baby’s eye boogers. It can be treated by surgical methods, such as tear duct probing and placement surgery, nasal lacrimal sac anastomosis surgery and so on. Three-month-old baby eye boogers may also be caused by other reasons, if accompanied by eye redness, tear overflow and other discomforts, parents should take their babies to the hospital in a timely manner, after clarifying the cause of the disease, the doctor will give the correct treatment.
