Aim: To analyse the epidemiological data, surgical technique, success rate, and complications of patients who underwent external DCR in Hospital Selayang from January 2015 to December 2016. Method: Retrospective case series. Results: A total of 21 eyes of 20 patients who underwent external DCR from January 2015 to December 2016 were identified and reviewed. There were 15 females (75%) and 5 males (25%). Age ranged from 5 to 75 years old, with a median age of 56 years old (IQR 23). Twelve patients presented with epiphora while eight patients presented with symptoms of dacryocystitis. One case was congenital, two were secondary nasolacrimal duct obstruction and the rest were primary nasolacrimal duct obstruction. All patients underwent external DCR under general anaesthesia. Silicone tube were inserted in 21 eyes, of which all were removed 3 months after the surgery except one patient whom had his tube dislodged accidentally. The overall success rate was 90.5% (n = 19), which was defined as no or minimal intermittent epiphora or no reflux on lacrimal irrigation at 12 months postoperative. There was one patient who had a cerebrospinal fluid leak treated successfully with intravenous antibiotics. Conclusion: The surgical success rate for external dacryocystorhinostomy was comparable to that of the global success rate of external DCR. This is attributed to the application of surgical technique such as anterior suspended flap modification and posterior flap excision.

Introduction: Dacryocystorhinostomy (DCR) is the treatment of choice for nasolacrimal duct obstruction. Although external DCR is regarded as the gold standard, endoscopic DCR is evolving as an equally-effective alternative. Objectives To compare the success rate of treating nasolacrimal duct obstruction by endoscopic endonasal method compared to the conventional DCR surgery.Materials and methods This prospective, comparative, non-randomised study was conducted in 2009 - 2010. Thirty consecutive patients undergoing endoscopic endonasal DCR (Group 1) and 30 consecutive patients undergoing external DCR (Group 2) between July 2009 and September 2010 at the oculoplasty unit of the Tilganga institute of ophthalmology were included in this study. A patent lacrimal passage on syringing and symptomatic improvement at six months after surgery was de¿ned as a successful outcome. The intraoperative and postoperative complications were also compared. Results Our study included 31 eyes of 30 patients in Group 1 and 34 eyes of 30 patients in Group 2. The success rate for endoscopic endonasal dacryocystorhinostomy was 90.3 % (95 % con¿dence interval 80 - 100) and external dacryocystorhinostomy was 94.1 % (95 % con¿dence interval 80 - 100). The difference of surgical success among the two methods was not statistically significant (p = 0.7). The rate of intra-operative and post-operative complications was similar in the two methods (p = 0.5). Conclusion: The short term outcomes and complication rates of endoscopic endonasal dacryocystorhinostomy and external dacryocystorhinostomy were similar.

Introduction: This study aimed to evaluate patient satisfaction over time in patients undergoing external dacryocystorhinostomy for primary nasolacrimal duct obstruction when done by a general ophthalmologist. Materials and methods: This prospective interventional case series was done in a secondary level eye hospital in the Midwestern region of Nepal from 1st January 2018 to 30th December 2018. Fifty-four consecutive adult patients diagnosed with primary nasolacrimal duct obstruction who underwent external dacryocystorhinostomy performed by a general ophthalmologist were included. The surgical success rate was determined at six months on the basis of the resolution of symptoms with patency on syringing. Postoperative patient satisfaction was evaluated 6 months after surgery with a standardized Glasgow Benefit Inventory and post-intervention questionnaire. Results: A total of 54 eyes were operated on within the study period and a larger number of surgeries were done in the age group 26-30 years. Female constituted 79.6 % and male 20.4% with a ratio of 3.9:1. Overall surgical success rate 6 months after surgery was 96.30%. The mean total Glasgow benefit inventory (GBI) score was 48.83 ± 23.87 (95% CI, 42.96- 56.95), mean general subscale score was 52.70± 23.28 (95% CI, 46.49-60.38), social support subscale was 49.69 ± 44.68 (95% CI, 41.15-60.35) and physical health subscale score was 37.07 ± 41.19 (95% CI, 27.48-49.26). Conclusion: The external dacryocystorhinostomy surgeries performed by general ophthalmologists achieved an excellent surgical success rate and good patient satisfaction proven by a validated questionnaire.

External Dacryocystorhinostomy

Introduction: Dacryocystorhinostomy (DCR) is the commonest surgery for nasolacrimal duct obstruction. Inhibition of the scarring process within the anastomosis and rhinostomy site which has been attributed to the failure of this procedure, might improve the success rate of DCR. The objective of this study was to evaluate the outcomes of DCR with Mitomycin-C (MMC) and to compare the results of DCR with and without MMC. Materials and methods: A hospital based, prospective study was conducted in patients with primary acquired nasolacrimal duct obstruction. Standard conventional DCR was performed upto the level of creation of flaps. Application of MMC 0.2 mg/ml in and around the ostium and underneath the created flaps for two minutes was effected with cotton pledgets. The area was thoroughly washed with normal saline after removal of the pledgets. Rest of the surgery was completed as usual. The patients were followed up on the first postoperative day, one month and three months post surgery. Results: A total of 60 cases, 30 in each group were allocated. The success rate of DCR with MMC was found to be 96.7% compared to 86.7% (p=0.35) in the DCR group at the end of three months duration. Conclusions: Intraoperative application of MMC during conventional DCR surgery provides a comparatively higher success rate than DCR without MMC without posing any extra financial burden and adverse drug reaction to the patient.

Aims and Objectives: To compare the success rates of non endoscopic endonasal dacryocystorhinostomy and conventional external dacryocystorhinostomy for the surgical management of primary acquired nasolacrimal duct obstruction. Materials and methods: A retrospective, nonrandomized, comparative interventional case series of 302 patients who underwent either endonasal or external dacryocystorhinostomy over a period of 2 years. All surgeries were performed by a single surgeon and patients with primary nasolacrimal duct obstruction with a minimum of 6 months post operative follow up were included in the study. While external dacryocystorhinostomy was performed using traditional technique, endonasal dacryocystorhinostomy was performed using direct method of nonendoscopic visualization. Results: Of the 302 cases included in the study 165 patients had endonasal dacryocystorhinostomy whereas 137 underwent external dacryocystorhinostomy. Success was defined by resolution of symptoms of tearing, a negative fluorescein dye disappearance test and patency of the canalicular system on lacrimal irrigation. In the external dacryocystorhinostomy group 124 (90.5%) patients had surgical success whereas 146 (88.5%) of the endonasal dacryocystorhinostomy patients had successful outcome. The overall success rate was 89.4%, and the difference of surgical success between the two groups was not statistically significant ( P=0.57). Conclusion: Non endoscopic endonasal dacryocystorhinostomy gives surgical results comparable to those of external dacryocystorhinostomy and is a viable alternative where dacryocystorhinostomy is indicated for primary acquired nasolacrimal duct obstruction.

Objective: In this study, we report the results of probing done in our clinic. We also want investigate role of late probing on outcome, especially in children older than 24 and 48 months. Methods: We retrospectively evaluated records of patients who underwent probing under general anaesthesia due to congenital nasolacrimal duct obstruction between 2013 and 2017 in Nigde Ömer Halisdemir University Faculty of Medicine in Nigde, Turkey. Success rates of probing for different age groups were compared. Results: 143 eyes of 123 patients were included in the study. Overall success rate was 93.7% (134 eyes out of 143). We found the success rate as 95.5 in 12–18 months age group, 93.3% in 18–24 months age group, 93.8% in the 24–48 months age group, 86.6% in the 48 months and older age group. Overall success rate in 24 months and older age group was 91.5%. The second operation was performed on seven of the nine patients where the initial surgery failed, and successful results were achieved in six patients. Success rate was 100% after the second surgery in patients older than 48 months. Conclusion: The success rate of probing is high in patients with congenital nasolacrimal duct obstruction from 12 to 84 months. In patients with congenital nasolacrimal duct obstruction who are older than 48 months probing is effective and should be first-choice in this age group in management of congenital nasolacrimal duct obstruction. Probing may be used even in older patients who had previous unsuccessful probing.
