background: complaining of tearing was found in some of our patients after phacoemulsification surgery for senile cataract. secondary acquired lacrimal drainage obstruction has been proposed to happen due to different causes. this study was performed at feiz hospital in isfahan, iran from september to december of 2004 to evaluate the effects of phacoemulsification surgery on tear drainage in ey...

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 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 ...

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...

AIM To assess retrospectively the results and complications of surgical techniques applied in the treatment of patients with trauma of the lacrimal drainage system. METHODS Out of 32 patients with lacrimal drainage system trauma included in the study, 25 were treated at the University Eye Clinic, Ljubljana Medical Center, Ljubljana, Slovenia, from 1999 to 2003, and 7 were referred for seconda...

Lacrimal sac tumors are rare with a clinical presentation that typically includes obstruction of the lacrimal drainage system and epiphora as the most frequent symptom. Cribriform adenoid cystic carcinoma (ACC) is the most common malignant epithelial tumor of the lacrimal gland and minor salivary glands; however, its occurrence in the lacrimal drainage apparatus is extremely rare. Given the rar...

We present two patients with dacryoliths and patent lacrimal drainage with intermittent tearing and without infection. Dacryoliths can be present in the lacrimal sac or lacrimal duct without acute or chronic inflammation. In these cases, we believe dacryolith formation was a causative factor of intermittent epiphora even with a patent drainage system, and we propose that dacryoliths and even fu...

PURPOSE To study the microsurgical anatomy of the lacrimal drainage system and to provide anatomical evidence for transnasal endoscopic lacrimal drainage system bypass surgery by autogenous tissue grafting. MATERIALS AND METHODS A total of 20 Chinese adult cadaveric heads in 10% formaldehyde, comprising 40 lacrimal ducts were used. The middle third section of the specimens were examined for t...

Lacrimal scintigraphy (LS) was performed in 860 lacrimal drainage systems (LDS) in 188 patients with bilateral epiphora and 226 patients with unilateral epiphora. A very high incidence of canalicular obstruction was found in these patients, the incidence being higher in the group with unilateral epiphora. It is suggested that a canalicular block is a commoner cause of obstructive epiphora than ...
