Quick Summary

The puncta lacrimalia are small openings located at the inner corner of each eyelid margin. These openings are part of the tear drainage system of the eye. Tears produced by the lacrimal glands flow across the eye and then enter these puncta. From the puncta, tears travel through small ducts called canaliculi into the lacrimal sac, which then empties into the nasolacrimal duct and drains into the nasal cavity. Blockage of these tear pathways can lead to conditions like dacryocystitis, an inflammation and infection of the lacrimal sac.1234
