Evaluation of the lacrimal apparatus with digital subtraction macrodacryocystography.
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.
