[Timed retrograde catheterization of the nasolacrimal duct as a method of treatment in congenital dacryocystitis and acquired stenosis of the nasolacrimal duct in children].

The authors propose a procedure of timed catheterization of the nasolacrimal duct for use in children with the duct stenosis and congenital dacryocystitis. The catheter is inserted for 7-10 days. Out of 27 children treated (20 cases of congenital dacryocystitis and 7 cases of the stenosis), a persistent effect was achieved in 24. The authors advocate the method as effective and promising in the above conditions.
