ObjectiveRadiological and anatomical study of the Lacrimal apparatus system in one-humped camel of Iran (Camelus Dromedarius) DesignProspective study AnimalsFive heads (cut above the third cervical vertebra) of adult Dromedary camels' cadavers were collected from the slaughterhouse of the Najafabad area of Isfahan Province, Iran. ProceduresThe anatomy of the nasolacrimal duct of onehumped camel...

PURPOSE To compare the effectiveness and patency of the TearLeader stent (PBN) for treatment of lacrimal system obstruction. METHODS A prospective study of 68 patients referred from the ophthalmology department with suspicion of lacrimal system obstruction. We placed 74 TearLeader PBN stents. Inclusion criteria were: complete obstruction of lacrimal duct with canalicula and lacrimal puncta pa...

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...

Two infants had congenital mucocele of the lacrimal sac. The diagnosis of this condition was aided by ultrasound. Congenital mucocele is one of the few indications for immediate lacrimal system probing in the neonatal period. Probing in both patients was successful.

Hemangiopericytoma (HPCT) rarely originates in the lacrimal sac; 7 cases have been reported previously and only 1 contained an ultrastructural study. In this article we report an additional case and review the previous reports. While the initial biopsy specimen showed nonspecific cytologic abnormalities, light and electron microscopic studies on the subsequently excised tumor demonstrated that ...

IN the vast majority of cases the aetiology of an acquired obstruction in the lacrimal drainage apparatus remains obscure. Overt infection is a common associate, especially with obstructions involving the naso-lacrimal duct. It is still not clear whether the infection is causal or sequential to the obstruction, or whether these two factors are simply part of a wider diathesis. At the present ti...

BACKGROUND From the 1990's onward, it has been possible to assess changes in the lacrimal duct by direct, minimally invasive diagnostic inspection with the aid of miniaturized endoscopes originally used in gastroduodenal surgery. It has been shown in this way that mechanical lacrimal duct stenosis often develops gradually as the result of recurrent chronic inflammation. Absolute stenoses are of...

BACKGROUND It is frequently stated in the literature that there is a common canaliculus (CC) in the lacrimal drainage system in about 90% of individuals; in the remaining 10%, the upper and lower canaliculi enter the lacrimal sac separately. To our knowledge, there is no quantitative study supporting this assumption. OBJECTIVE To investigate the frequency of the CC and other anatomical types ...

Tumors arising at the lacrimal sac are extremely rare, as a limited number of cases have been reported worldwide. They are commonly primary and the majority of them are malignant and epithelial in origin. Adenocarcinomas account for a small percentage of these tumors. Treatment of local disease mainly includes complete surgical resection. However, metastatic disease has a poor prognosis and the...

INTRODUCTION Ocular injuries commonly involve the lacrimal system. CASE A 14-year-old male had an eyelid injury with a canalicular tear. An angiocatheter tube was used as a stent for canalicular reconstruction. The focus of this report is on the method used, as well as the material for the repair in a rural hospital. CONCLUSION Angiocatheter tube can be a suitable alternative to silicone tu...
