Sir,
We thank Dr. Yasri for comments on our paper. The diagnosis of Congenital Nasolacrimal Drainage Obstruction (NLDO) in this study was based on history of symptoms dating back to birth (65% of patients) and a definite absence of other causes of NLDO. The records reviewed for this retrospective study did not contain details of antenatal and perinatal history of the subjects to allow for proper evaluation of risk factors however from the study, socio demographic factors contributed to timing of presentation of the subjects. From 2008, our centre had acquired facility for endoscopic (dacrocystorhinostomy) DCR and a study comparing external and endoscopic DCR is already been undertaken. The above study only utilized external DCR which we concluded to be effective treatment for NLDO in the hands of an experienced surgeon,though we acknowledge that use of stent is controversial.
