Primary Acquired Nasolacrimal Duct Obstruction Clinical Trial
Official title:
External Dacryocystorhinostomy Versus Canalicular Silicone Intubation With Mitomycin C in Primary Acquired Nasolacrimal Duct Obstruction
While external DCR is the gold standard procedure for primary NLDO as well as complicated cases, SI with MMC could achieve comparable success rates in primary acquired NLDO, hence should be considered as an alternative as a safe and minimally invasive procedure.
Purpose: To compare external dacryocystorhinostomy versus canalicular silicone intubation
with the use of Mitomycin C (MMC) in primary acquired nasolacrimal duct obstruction (NLDO).
Methods: the study was carried out at the department of Ophthalmology, Menoufia university
Hospital, Egypt, between June 2012 to July 2014. Fifty-six patients who were diagnosed with
primary acquired NLDO. Patients were randomly allocated into two groups: thirty cases
underwent external DCR and twenty-six cases underwent silicone intubation with MMC.
