Patient's question:
The child was born not long ago, and their eyes always tear up, and they also love crying. Why do young children secrete yellow substances in their eyes?Doctor's answer:
The obstruction of this disease can occur at any location between the lacrimal canaliculus, the main lacrimal duct, the junction of the lacrimal sac and the nasolacrimal duct, and the lower opening of the nasolacrimal duct (Hasner's valve). It can be a single obstruction or multiple obstructions, which is due to the incomplete opening during the segmentation and tubularization of the lacrimal duct primordium epithelial columns during the formation of the nasolacrimal duct. Currently, lacrimal duct probing can be considered, but it is generally recommended to undergo lacrimal duct stenting surgery!
