Size variation of the lacrimal punctum in adults

Abstract

This is the first reported study on accurate computerized measurements of lacrimal punctal size in normal adults. There was a wide variation found between patients. The lower lid puncta were consistently noted to be larger than those of the upper lids. This is clinically significant in dry–eye patients who may need to be treated with punctal plugs of various sizes. © 1988 Raven Press, Ltd., New York.
