The main objective of the present study was to prospectively evaluate long-term surgical success and safety in patients with nasolacrimal duct obstruction treated with a multidiode transcanalicular laser and bicanalicular silicone intubation stenting. 42 patients treated with transcanalicular laser dacryocystorhinostomy for nasolacrimal duct obstruction were prospectively enrolled. In all cases...

In our previous study the inclination of nasolacrimal canal in relation to Frankfurt horizontal plane has been analysed on 71 anatomically preparated human skulls by introducing the probe through canal. The results of that study showed that the alpha angle in the frontalplane was greater than 91 degrees in 27% of cases, i.e., nasolacrimal canals descend diverging in relation to the median plane...

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 ...

A gross anatomical study was made on the lacrimal apparatus in seventeen adult camels (4-10 years age), and three foetuses. The lacrimal gland is situated between the caudodorsal aspect of the eyeball and the supraorbital and frontal process of the frontal and zygomatic bones, respectively. The gland consists of two lobes, cranial and caudal. The excretory ducts were 3-4 in number, and opened i...

Purpose Primary ductal adenocarcinoma arising in the structures of the lacrimal apparatus is extremely rare, and the entity is considered a lacrimal counterpart of salivary duct carcinoma, of which the majority are known to express androgen receptor (AR). Less than 10 cases of AR-positive carcinomas of lacrimal gland or lacrimal sac have been described. Observations We present a primary ducta...

PURPOSE To compare success and extrusion rates of the monocanalicular and bicanalicular Crawford intubation systems (JEDMED Instrument Company, St. Louis, MO). METHODS A retrospective review of all children who were diagnosed as having congenital nasolacrimal duct obstruction and treated with lacrimal intubation from 2005 to 2014 was performed. The total number of eyes included was 168 (75 an...

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...

purpose: to compare success rates of external dacryocystorhinostomy (dcr) with and without bicanalicular silicone intubation for management of primary acquired nasolacrimal duct obstruction. methods: in a randomized clinical trial study, 52 patients with primary acquired nasolacrimal duct obstruction underwent external dcr. patients were randomly enrolled into two groups. in the 1st group, exte...
