Outcome of Syringing and Probing In Congenital Nasolacrimal Duct Obstruction in Children above Two Years of Age: A Prospective Study
Annals of International medical and Dental Research
Congenital Nasolacrimal duct obstruction (CNLDO) is one of the most common problems in the pediatric age group. It is the commonest cause of childhood epiphora. In most cases it is caused by incomplete canalisation of the nasolacrimal duct (NLD). Aim: The present study was conducted to determine the success rate of primary nasolacrimal duct probing in children older than two years of age. Methods: The present prospective study was conducted in the post graduate department of ophthalmology,
... ophthalmology, Sher-i-Kashmir Institute of Medical Sciences and hospital Bemina. Fifty two eyes of forty two children underwent probing and syringing for nasolacrimal duct obstruction under general anaesthesia. Follow up was done at first week, fourth week and three months. Success was defined as complete absence of sign and symptoms. Statistical analysis was performed using SPSS version 17.0. P value of less then 0.05 was considered significant. Results: Success rate of S&P in our study was found to be 94.23 %. Simple obstruction was encountered in 44 (84.61 %) eyes and all resolved successfully post S&P. Complex obstruction was encountered in 8 (15.39%) eyes and only five resolved successfully post S&P giving a success rate of 62.5 % only. Conclusion: late probing should be performed as an initial surgical step in the management of every case of CNLDO presenting late in the course of the disease (> 2 years), before more invasive procedures are attempted.
