    Abstract:
    PURPOSE: To compare two distinct surgical techniques in the management of chronic Primary Lacrimal Canaliculitis (PLC) with clinically detectable concretions. MATERIALS AND METHODS: Inclusion criteria: Patients presenting with symptoms consistent with the diagnosis of primary lacrimal canaliculitis (PLC) with ocular involvement were gathered. Gomori-Grocott Methenamine Silver test was used for concretion staining. Two groups were identified based on the surgical technique. Group A consisted of patients who underwent a punctum sparing canalicular curettage using a chalazion curette, while the patients in Group B underwent one-snip punctoplasty with lateral canaliculotomy. Failure was defined as recurrence of the initial symptoms at any time (ocular and canalicular inflammation with purulent discharge and pouting punctum). The results were analyzed by comparisons using a Fisher's exact test. RESULTS: Ninety-six consecutive patients (96) with a confirmed diagnosis of PLC underwent surgical treatment between 1987 and 2017. Data were collected and divided based on the surgical technique discussed above (Group A and B). Group A: 51 cases with a mean follow-up time of 22 months [1-224] presented with a mean age of 51.5 [25-83] and a surgical failure rate of 19.6%. Group B: 45 patients with a mean follow-up time of 27 months [1-176], a mean age of 68 [17-87] years and a surgical failure rate of 4.4%. Statistical significance was demonstrated, with a p-value of 0.033, odds ratio (OR) of 0.1936 and Standard Deviation (SD) at a 95% confidence interval of [0.0195-0.9885]. CONCLUSIONS: One-snip punctoplasty with lateral canaliculotomy is a simple, fast and effective procedure that allows better anatomical visualization intraoperatively and is thus shown to be statistically superior to punctum sparing canalicular curettage using a chalazion curette.
