• Applications of cautery to the mucosa and muscle at the base of the lacrimal papillae can result in retraction of the walls of the punctum, reestablishing patency.
A relationship may exist between the cause of stenosis of the lacrimal papillae and stenosis at other juncture points in the lacrimal excretory system.
