background and objectives: primary acquired nasolacrimal duct obstruction (pando) is a common ocular problem. clinical presentation can range from simple tearing to a life-threatening condition. the exact pathophysiology of obstruction is not completely understood. in this study, therelationship between pando and nasal mucosal goblet cells was investigated.  materials & methods: in this ca...

PURPOSE Dacryoscintigraphy is widely known to be an effective modality in diagnosing abnormalities of the lacrimal system that cause epiphora (pathological overflow of tear). However, dacryoscintigraphy rarely serves beyond the simple diagnostic use for lacrimal duct obstruction. In our study, dacryoscintigraphy results of patients with functional lacrimal duct obstruction are newly classified ...

Epiphora is a frequent reason for ophthalmologic consultation. Among the multiple causes, obstructions of the lacrimal excretory system are common. Sacal and postsacal obstructions are much more frequent than presacal obstructions. Obstruction at the level of the Hasner's valve is rare and likely underestimated. The authors report the clinical history and the imaging of 3 patients with a cystic...

OBJECTIVES The aim of this study was to assess the concomitant perioperative procedures, the causes of nasolacrimal duct obstruction, the success rate, and the complications associated with endonasal dacryocystorhinostomy (ENDCR). METHODS In this single-center retrospective study, 98 patients underwent 104 ENDCRs between January 1994 and February 2006. There were 78 patients with 84 nasolacri...

Obstruction of the lacrimal pathway is manifested by epiphora, infection, and blurred vision as well as ocular and facial pain. Conservative treatments only achieve temporary relief of symptoms, thus surgery is the treatment of choice. Dacryocystorhinostomy (DCR) is recognized as the most suitable treatment for patients with obstructions of the lacrimal system at the level of the sac or in the ...

There is significant variation in how ophthalmologists treat children with congenital obstructions of the nasolacrimal ducts. In the United States, some perform an in-office probing procedure on infants, whereas many prefer to wait until after 1 year of age when more than 90% of the obstructions will have resolved spontaneously. Whether or not to instruct parents to massage the lacrimal sac and...

AIM The aim of this study was to report the preliminary experience with the techniques and utility of navigation-guided, 3D, computed tomography-dacryocystography (CT-DCG) in the management of secondary acquired lacrimal drainage obstructions. METHODS Stereotactic surgeries using CT-DCG as the intraoperative image-guiding tool were performed in 3 patients. One patient had nasolacrimal duct ob...

PURPOSE To evaluate the efficacy of Palmaz balloon-expandable metallic stents for the maintenance of luminal patency in the treatment of recurrent nasolacrimal duct, obstructions after failed transluminal balloon dilatation. METHODS Metallic stents were implanted in the nasolacrimal duct of four patients with recurrent epiphora. All the patients had already undergone transluminal balloon dila...

Lacrimal duct obstruction is a common eye disease, and obstruction of the nasolacrimal duct accounts for over 50% of these cases. Nasolacrimal duct obstruction is usually treated surgically. Lacrimal retrograde catheterization is a novel surgical approach with a high success rate and a relatively high recurrence rate. In this study, we examined the postoperative pathological changes in the lowe...
