Abstract

In the management of a patient with epiphora, appropriate investigation is important in arriving at the cause of obstruction, and in helping to outline a plan for management. Standard dacryocystography has been modified by utilizing the techniques of intubation, distension, macrography, and subtraction to produce optimal anatomical information. Lacrimal nuclear scanning with the addition of rapid sequence display and computer interfacings produce the most sophisticated functional information regarding tear drainage. The role of plain films and computerized tomography in lacrimal drainage pathway disease is outlined.

    Dacryocystography is the most common and useful method to obtain anatomic information of the nasolacrimal drainage system.29,30 We selected to use dacryocystography because it is readily available and safe and because the results can be obtained quickly and at low cost.31–34 Other imaging techniques (e.g., lacrimal scintigraphy,35 computed tomography,36,37 and magnetic resonance imaging29,31,32) have been used to evaluate the nasolacrimal drainage system.

    Citation Excerpt :

    Additional diagnostic testing is necessary when patency is demonstrated but no obvious anatomic abnormality has been found to explain the patient's tearing complaints. Some clinicians believe radiographic testing should be performed in all patients,28,34 but this view is not held by all. An occluded nasolacrimal duct, with or without accompanying dacryocystitis, is most commonly observed in a middle-aged woman in whom the cause is not apparent (Fig. 2).3
