We report a case of congenital lacrimal sac fistula located on the temporal side of the lateral canthus. A systemically healthy 1-year-old girl came to the outpatient clinic with a complaint of tearing on the temporal side of the right lateral canthus since birth. On examination, a small orifice was found in the skin on the temporal side of the lateral canthus. There was no evidence of inflamma...

PURPOSE To determine whether the lining epithelium of the human lacrimal sac and nasolacrimal duct synthesizes TFF peptides (formerly P-domain peptides, trefoil factors), a family of mucin-associated secretory peptides. METHODS Expression of TFF peptides in human lacrimal sac and nasolacrimal ducts was monitored by reverse transcription-polymerase chain reaction and Western blot analysis. Ant...

OBJECTIVE To evaluate the nasolacrimal ostium created after successful external dacryocystorhinostomy. METHODS This prospective study included 41 successful primary external dacryocystorhinostomies performed in 41 patients with nasolacrimal duct obstruction (33 women and 8 men; age range, 19-75 years). The dimensions of osteotomy were measured during surgery. Patients alternately underwent ei...

Lacrimal scintigraphy (LS) was performed on asymptomatic lacrimal drainage systems and the results were evaluated to understand the physiology of lacrimal drainage. It was found that a physiological obstruction can exist at the level of the nasolacrimal duct in normal asymptomatic individuals, and it is suggested that this obstruction is due to the resistance offered by the valve of Hasner, whi...

BACKGROUND AND PURPOSE Several techniques have been used to image the nasolacrimal system, providing functional (dacryoscintigraphy) or morphologic (dacryocystography, CT dacryocystography [CTD]) information. Using gadopentetate dimeglumine-diluted solution injected into the lacrimal canaliculus or instilled into the conjunctival sac, we compared the sensitivity of MR dacryocystography (MRD) wi...

OBJECTIVES To evaluate a new technique of modified endoscopic dacryocystorhinostomy involving the creation of a large posterior flap at the lacrimal sac and to compare its success rate with that of the conventional endoscopic method of excising the entire medial lacrimal sac wall as a surgical treatment for epiphora caused by nasolacrimal duct obstruction. DESIGN Retrospective, interventional...

female patient, 54 years old, complained of excessive earing in the right eye for 12 years. After four years, he presented with progressive obstruction of the nasal assages. Approximately one year before presenting to his service, a bulging swelling, painful upon compression, ppeared near the inner corner of the right eye. On physial examination, she demonstrated epiphora in the right eye nd a ...

BACKGROUND The aim of this study was to report the outcomes of powered endoscopic dacryocystorhinostomy (PEnDCR) in patients with lacrimal sac within the sinus. MATERIALS AND METHODS Retrospective analysis was performed on all patients who underwent PEnDCR and were intraoperatively documented to have complete lacrimal sac in sinus. Data collected included demographics, clinical presentations,...

The Lacrimal apparatus starts from the lacrimal gland and ends at the Nasolacrimal ducts. The apparatus consists of the lacrimal gland and the lacrimal pathway. The integrity of the Lacrimal Apparatus in its secretory function and in its drainage mechanism is most vital for the normal functioning of the eye. Any factor which upsets the drainage mechanism distal to the sac or at the Nasolacrimal...
