Deficiency of the tears or obstruction to the free flow of tears predispose to infections of the lacrimal system. The relevant anatomy of the lacrimal system and the pathologic conditions leading to obstruction are outlined. The clinical manifestations of infections of the lacrimal gland, the canaliculus, and the lacrimal sac are described, and the basis for medical and surgical treatment is discussed.
Patients who suffer from epiphora can benefit from reconstructive surgery in many cases of obstructive and nonobstructive lesions of the lacrimal apparatus. We describe our technique of digital subtraction macrodacryocystography (DSM) and discuss its efficacy in the evaluation of various abnormalities involving the lacrimal drainage pathway. A variety of pathologic conditions of the lacrimal apparatus are portrayed. DSM is an accurate, easy to perform, but relatively unrecognized method of anatomic localization of obstructive lesions within the lacrimal drainage system.
A- und B-scan echography is a useful method for the examination of certain parts of the lacrimal drainage system. In most cases it can substitute for dacryocystography and other expensive methods in the diagnosis of lacrimal sac diseases. Older methods of echography for examination of the lacrimal sac are direct contact, water bath, and rarely transocular contact methods. We have developed a new method, in which a rubber tube filled with fluid is placed between the transducer and the skin surface. Comparison of these methods demonstrates that this is the best method for ultrasound diagnostics of the lacrimal sac because it can be carried out as easily as the direct contact method, and the quality of the echograms is as good as in the water bath method. A special advantage is that causing an infection in the patient with the ultrasound probe can be avoided.
