biocon commented on the word punctum lacrimale
Punctum lacrimale signifies a minute circular aperture in the medial opening into the nasolacrimal sac. Puncta lacrimalia drain the tears that proceed from the lacrimal glands through the lacrimal ducts to the conjunctiva. Puncta clogged with mucus or dirt cause irritation and discomfort. There are four puncta lacrimalia, one in the medial part of each eyelid.
