Fig. 3. The signs and symptoms of primary canaliculitis and the surgical results of a mini-invasive canaliculotomy with curettage are shown.

A The inferior canaliculus illustrates punctal erythema and edema, mucopurulent discharge from the punctum. B One month after surgery, the position of the silicone tube intubation is shown in the picture. C The image shows an undamaged punctum and a well-healed incision during a 12-month follow-up (11 months after silicone tube removal).
