Congenital Nasolacrimal Duct Obstruction Clinical Trial
Official title:
Recanalization of Congenital Nasolacrimal Duct Obstruction by Endodiathermy Probe and Intubation Versus Intubation Only
The purpose of the current work is to assess the efficiency and success rate of endodiathermy probe followed by intubation in children more than 2 years compared to the success rate of intubation (as a standard method) which varies from 75% to 85% in several studies

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | recanalization of nasolacrimal duct | compare the efficiency of endodiathermy probe followed by intubation versus probing with metal probe followed by intubation by epiphora (overflow of tears onto the face) increase tear film meniscus ( more than 1mm in height) mucous discharge Fluorescein disappearance test (Normally, little or no dye remains after 5 minutes. Prolonged retention is indicative of inadequate lacrimal drainage) |

Secondary | complication | Record any complication in two procedures as tube migration, tube extrusion, infection or need for additional procedure. | 6 months |
