OBJECTIVE To determine the usefulness of "routine" lacrimal sac biopsy to evaluate unsuspected neoplasm or systemic disease in patients with acquired nasolacrimal duct obstruction. DESIGN Noncomparative, interventional case series with histopathologic correlation. PARTICIPANTS Review of charts revealed histopathologic reports on 302 specimens from 258 patients who had undergone routine dacr...

The lacrimal drainage system consists of the puncta (upper and lower within the eyelids) which are the opening to the upper and lower canaliculus. These meet at the common canaliculus and open into the lacrimal (tear) sac. This runs parallel to the nose and is separated from the middle meatus of the nasal cavity by two thin plates of bone. It continues down to become the nasolacrimal duct (tear...

Lacrimal punctal agenesis is a rare cause of congenital epiphora and may occur in isolation or in combination with other lacrimal drainage anomalies such as pathologies of the canaliculus, lacrimal sac, and nasolacrimal duct. It rarely occurs in a familial manner. If diagnosed earlier, management of this condition may be as simple as a sharp opening or may necessitate more complex interventions...

AIMS To determine the efficacy of antegrade balloon dilatation of postsaccal lacrimal stenosis in adults. METHODS Balloon dilatation was performed in a series of 30 patients with complete nasolacrimal duct obstructions and epiphora. Obstruction was diagnosed by canalicular irrigation and transcanalicular endoscopic examination of the lacrimal pathway. Except for four cases in which general an...

in a prospective survey, 200 cases of operated chronic dacryocystitis were divided into three groups according to the kind of operation, and the respective results are as follows: group i includes 100 cases in whom the lacrimal bone was removed (8mm x 8mm) and a 6mm diameter catheter was used (as a duct between the lacrimal sac and nasal cavity). the recurrence rate within one year was 24 % . g...

Lacrimal duct obstruction disease (LDOD) is a common ophthalmologic disease. Stent implantation surgery is one of the most effective therapies. In this study, we intended to find out the satisfactory biodegradable stents containing poly-L-lactic acid-polycaprolactone-polyethylene glycol (PLLA- PCL- PEG) complexes for therapeutic application in LDOD. Stents made of PLLA- PCL- PEG complexes in va...
