1.The nasolacrimal drainage system drains the tears from the eyes. This system is susceptible to variety of pathological entities presenting clinically as epiphora 2. Imaging provides both structural and functional information of the nasolacrimal duct (NLD) system 3.The digital subtraction dacryocystography and dacryoscintigraphy provides structural and functional information respectively, whilst the cross sectional studies such as CT and MRI provide additional soft tissue information. 

1.Imaging anatomy of the nasolacrimal apparatus using Digital subtraction dacryocystography with schematic illustration. 2.Aetiology of epiphora is classified under Congenital, Inflammatory, infection, traumatic, neoplastic and functional. Each topic is described with relevant examples using multi-modality imaging. Examples of some of the cases include Absent inferior canaliculus, Dacrocystocele, Chronic canaliculitis, Aspergilosis invading the nasolacrimal duct (NLD), Dacrocystolith, orbital floor fracture involving the NLD, Sinonasal neoplasms invading the NLD ,functional epiphora with normal anatomical patency of NLD etc., 3.Post-operative imaging appearance of Dacrocystorhinostomy- A surgery commonly performed in the management of epiphora. 4.Emerging Role of MR dacryocystography and the limitations.
