AbstractThis study aimed to introduce a mini-invasive surgical approach without damaging lacrimal punctum for treating primary chronic canaliculitis (PCC). A retrospective analysis of 35 patients (35 eyes) suffering from PCC were recruited in the study. The surgery method is described briefly below: After making a conjunctival incision about 3-mm in length along the horizontal canaliculus at about 3-mm to the nasal of punctum, a curette of 2-mm diameter was used to evacuate the concretions through the incision of canaliculus. After evacuating all concretions, a silicon tube was inserted into the lacrimal duct through canaliculus to nasal cavity. With a follow-up of 12 months, all patients had resolution of symptoms of inflammation and no recurrent case was found. The anatomical success was achieved in 34 cases (97.1%). The functional success was achieved in 32 cases (91.4%). Key Words: Primary chronic canaliculitis, Mini-invasive, Silicone tube.
