Significance of Nasolacrimal duct
The nasolacrimal duct is a critical channel that drains tears from the eye to the nasal cavity. It plays a significant role in the effectiveness of eye drops and the contact time of the medication with the tissue. Additionally, obstruction of this duct may lead to conditions like dacryocystitis. The duct's connection between the eye and nose also allows for the potential transfer of infections, thereby contributing to various ocular disorders.
