An eyelash nidus for dacryoliths of the lacrimal excretory and secretory systems.

We treated two patients with dacryolithiasis secondary to an eyelash. The first patient underwent dacryocystorhinostomy for a stone within the lacrimal sac. In the second patient the dacryolith was removed from a lacrimal gland ductule. Eyelashes found in the tear film or conjunctival fornices during routine examination should be removed to prevent the possible occurrence of dacryolithiasis.
