Question
A three-year-old girl has a small hole on the outer side of the corner of her left eye, which releases fluid when pressed. How did this condition form? How should it be handled?
Answer
This condition may be dacryocystitis, caused by a blocked or narrow nasolacrimal duct, often seen in conditions such as trachoma, lacrimal duct injury, rhinitis, nasal septum deviation, nasal polyps, and hypertrophy of the inferior turbinate. Due to obstructed tear drainage, bacteria can multiply in the lacrimal sac, leading to chronic inflammation of the lacrimal sac mucosa and producing mucus secretion. Additionally, it may also be related to facial fistula, which is caused by abnormal development of facial tissue during embryonic development. It is recommended to keep the area clean, eat a light diet, and avoid pressing with hands. If there is no regional infection and no symptoms, no special treatment is needed; if infection occurs, fistula removal can be performed under anesthesia.
