Carcinomas of the lacrimal drainage system
Survey of Ophthalmology, 2020Malignant tumors of epithelial origin are the most frequent neoplasms of the lacrimal drainage system (LDS). A total of 539 cases are reported in the literature from 1960 to 2019. LDS carcinoma is a disease of the middle-aged and elderly population, with a median age at diagnosis of 57 years. Overall, there is a slight male predominance.

Carcinomas of the lacrimal drainage system
Head & Neck, 1993AbstractPrimary carcinomas of the lacrimal drainage system are rare. These malignant neoplasms typically present as noncompressible, nontender masses with low‐grade dacyrocystitis and/or unilateral epiphora. Lymph node metastasis may occur late in the disease course. Complete surgical resection is the best treatment choice; extensive procedures such as

Lacrimal Drainage System Diseases
2016A delicate equilibrium between tear production and loss is controlled by the lacrimal system. Biological, environmental, and physical factors continuously influence this balance. Tear production in excess of loss directly causes tearing, whereas tear loss in excess of production stimulates reflexive tear production, which may also lead to epiphora [1].

Obstruction of the lacrimal drainage system
Current Opinion in Ophthalmology, 2002This review covers evolving concepts in lacrimal outflow obstruction. Recent studies have increased our understanding of the surgical anatomy and pathophysiology of the lacrimal drainage system through radiologic, clinical, and microbiologic techniques.

Journal of Hydrology, 1975
Abstract This paper describes the form of a number of limestone drainage systems on the Gower Peninsula, South Wales. The effect of system morphology on seasonal variation in flow pattern and solute load at spring sites is examined and the systems ordered according to the degree of development of the conduit flow component and the integration of ...

Detergents in drainage systems for buildings
Water Research, 2001Current soil waste vent (SWV) system design guides aim to produce ventilated drainage networks for buildings which protect attached water trap seals from unwanted air pressure effects. Such effects may cause trap seal failure that are caused by airflow induction during discharge.

Tumors of the Lacrimal Drainage System
Orbit, 2010Tumors of the lacrimal drainage system are rare, but potentially life-threatening. They comprise a large and variable spectrum of entities grouped into three major categories of primary epithelial, primary nonepithelial and inflammatory lesions. The most common primary epithelial tumors include papilloma, squamous cell carcinoma and transitional cell ...

A “friendly” system for pericardial drainage
Cardiology in the Young, 2000AbstractWe describe an alternative to the water-seal system, suitable for drainage of pericardial and eventually pleural effusions, which has been shown to safe, effective, not painful, and rather “friendly”, providing patients with a smoother clinical course.

1986
There are several conditions involving the lacrimal drainage system that may require imaging techniques for diagnosis and management. The most common of these is epiphora, which is the abnormal overflow of tears and usually is secondary to obstruction of the passages.

Evaluation of the Lacrimal Drainage System
Ophthalmology, 1978Methods of testing for lacrimal drainage insufficiency and a modification of the Jones fluorescein dye tests are presented. Despite their excellence, Jones tests have never been widely employed because of difficulty in dye retrieval. The modification consists of instilling one drop of the dye three times at 15 second intervals, and after a one minute ...
