Question
Why do young children’s eyes produce yellowish substances?
Answer
This is due to incomplete segmentation and tubularization of the epithelial columns during the formation of the lacrimal duct, which may cause obstruction at any part between the junction of the lacrimal duct, lacrimal sac, and nasolacrimal duct to the lower opening of the nasolacrimal duct. It is recommended to undergo a lacrimal duct probing procedure or consider performing a lacrimal duct intubation surgery.
