Epiphora is a bothersome condition seen in chronic dacryocystitis. The mainstay of treatment is surgical, that is creating an opening to establish a drainage pathway. With the advent of endoscope, endonasal DCR has gained popularity. Use of silicone stent in endonasal DCR has added advantage in improving the surgical outcome. And the use of DOS system in improving the success rates of endonasal DCR: (Mohammad et al. in Clin Ophthalmol 8:2491–2499, 2014) a total of 35 patients with chronic dacryocystitis were subjected for endonasal DCR with silicone bicanalicular stent. Patients were followed up at an interval of 1 week, 3 weeks, 6 weeks and 6 months post surgery. DCR ostium parameters were evaluated using DOS system. Silicone stent removal was done at sixth week and evaluated for success. The success rate in our study was 89%. The DOS score of the patient with successful surgery had a score of more than 30 and in the failed cases the score was between 22 and 28. The success rate of the procedure primarily depends on the ostium parameters and the position of the silicone stent. The DOS scoring system can be suitable tool in evaluating the same.
