What is the most common cause of epiphora in newborn?

Symptoms usually sta after 3 weeks of age with epiphora, matting of lashes and discharge. Conservative management with topical antibiotics and lacrimal sac massage is done in patients upto age of 9-12months. Initial probing is done when child presents beyond the age of 9-12 months or in case of failure of 3 months of conservative therapy. Ref: Clinical Ophthalmology edited by Sandeep Saxena page 757.
