Common Mistakes
- Misspelling as 'nasolacrymal duct' or 'nasolacrimial duct'.
- Confusing it with the 'lacrimal canaliculi' (the smaller ducts that feed into it).

Primarily in ophthalmology (eye care) and otolaryngology (ENT - ear, nose, and throat).
Yes, obstruction can lead to infection and inflammation of the lacrimal sac, a condition called dacryocystitis.
