The upper lacrimal drainage system starts at the puncta, canaliculi, and the common internal puncta (opening of common canaliculus) and drains into the lacrimal sac.

Justin Older, MD, an oculoplastic specialist here, instead uses the device to dilate the stenotic punctum and canaliculus. Dr. Older has used the mini-Monoka for the past 2 years.

The tears go through small ducts called the superior and inferior canaliculi and then flow through the lacrimal sac and the nasolacrimal duct, and finally into the nose (Figure 1a).

Introduction The lacrimal drainage system is made up of a succession of rivers, holes and lakes. First are the palpebral rivers, which run along the palpebral margins. These superficial rivers end ...

Under normal conditions, tears in the eyes are drained into the lacrimal sac through small openings called the upper and lower puncta located at the inner corner of the eye (called medial canthus).

We do know that lacrimal gland cancers can develop at any age. There are different types of lacrimal gland cancer. The average age of diagnosis depends on the type of lacrimal gland cancer. For a type ...

Lacrimal irrigation and probing can demonstrate a punctal or canalicular problem. One passes a 23G cannula or #00 Bowman probe into the canaliculi and examines whether the medial wall of the sac ...
