Size variation of the lacrimal punctum in adults

Ophthalmic Plast Reconstr Surg. 1988;4(4):231-3. doi: 10.1097/00002341-198804040-00006.


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.
