PURPOSE: Few studies have focused on the intranasal localization of the lacrimal sac during endoscopic dacryocystorhinostomy: landmarks in order to find the medial wall of the lacrimal sac have been described, but there is a lack of description of methods for the verification of the complete marsupialization of the lacrimal sac during surgery. In this report, we propose an easy and effective method for certain intraoperative identification of lacrimal sac. METHODS: A method in order to verify the effective marsupialization of the lacrimal sac is applied and described: to ensure that the opening of the sac in the nasal cavity is complete, the surgeon should identify the Rosenmuller valve, which is the end of the common canaliculus in the lacrimal sac...

PURPOSE: Epiphora is sometimes associated with an absent or occluded lacrimal drainage punctum (or puncta). This study uses noninvasive "enhanced depth" anterior segment optical coherence tomography (OCT) to give improved characterization and understanding of absent or fully occluded puncta and the underlying canaliculus. METHODS: Anterior segment spectral domain OCT images were collected prospectively from 9 lower puncta of 6 patients with epiphora and absent or fully occluded puncta, not amenable to dilation in clinic, to see if a canaliculus was visible on OCT imaging below the occluded punctum...

A 25-year-old man presented with a mass on the right medial canthus after a successful dacryo cys torhinostomy performed 3 years ago. On examination, there was a firm, nondepressible mass inferior to the medial canthal ligament and a linear vertical scar on the lateral wall of the nose. Syringing through the right lower punctum indicated his lacrimal system was patent. Computed tomography and magnetic resonance imaging disclosed a large cystic lesion in the lacrimal sac fossa. No bone erosion was detected. The mass was approached through a tear trough incision and completely resected...
