Review the technique of dacryocystography that was originally described by Ewing in 1909 using bismuth subnitrate as contrast media. It was the first method used to evaluate the lacrimal drainage system. Describe the lacrimal drainage system anatomy in dacryocystography including essential structures as Rosenmüller valve, Krause valve and Hasner valve. Recognize nasolacrimal drainage system pathologies, specially causes of obstruction as infectious, inflammatory, congenital, tumoral and traumatic. Discusses and illustrate other imaging methods including ultrasound, computed tomography, magnetic resonance imaging and nuclear medicine.
