It is very common for children to have yellow and sticky eye droppings, which are mostly caused by bacterial infections of the conjunctiva, tear ducts or tear sacs of the eyes due to poor eye hygiene. The most common cause of this condition is bacterial conjunctivitis, which is often referred to as “pink eye”, and is mainly due to poor hygiene, frequent rubbing of the eyes with dirty hands, or using other people’s towels. The symptoms are redness and swelling of the conjunctiva and bulbar conjunctiva, and yellow-green or yellow-white mucousy discharge. The main treatment for this is topical application of anti-inflammatory drops and strict eye hygiene during treatment, not sharing washbasins, towels and other toiletries to prevent infection. In addition, children’s tear ducts are often imperfectly developed, so narrowing and blockage of the tear ducts are common, and bacteria may accumulate in the tear ducts or tear sacs, causing infections and other inflammatory manifestations. In addition to medication, lacrimal duct irrigation or exploration or surgery is needed to open the lacrimal duct to achieve a better treatment.
