Punctal dilatation and non-incisional canalicular curettage in the management of infectious canaliculitis.

OBJECTIVE

To describe the outcomes of punctal dilatation and non-incisional canalicular curettage in patients with infectious canaliculitis.

METHODS

A retrospective analysis of 53 canaliculi of 47 eyes of 46 consecutive patients diagnosed with canaliculitis was performed from November 2015 to December 2018. All patients were treated with punctal dilatation and a non-incisional canalicular curettage. Parameters studied include demographics, clinical presentation, microbiological analysis, management and treatment outcomes. The outcome measures were clinical resolution of canaliculitis and resolution of epiphora.

RESULTS

The mean age at presentation was 59.34 years with female preponderance (M:F = 19:28). Left eye was more affected (64%, n = 30) as compared to the right (36%, n = 17). Only one patient presented bilaterally. Lower canaliculus was most commonly involved (68%, n = 32). Six eyes showed involvement of both upper and lower canaliculus. Presenting symptoms include discharge (81%), swelling of the eyelids (64%), watering (55%), redness (51%) and pain (39%). Punctal dilatation and non-incisional canalicular curettage were performed using punctum dilator and a small chalazion scoop (1 mm Meyhoefer chalazion curette). Of the 53 involved canaliculi, 14 canaliculi of 14 eyes underwent a repeat curettage for complete resolution and 1 canaliculus underwent the same procedure thrice. The most common micro-organisms isolated were Streptococci species (28% cases). At a mean follow-up of 6.8 months, resolution of canaliculitis was achieved in all patients; however, epiphora persisted in two eyes (4%).

CONCLUSION

Non-incisional canalicular curettage is a minimally invasive technique with good preservation of the punctal and canalicular anatomy. It also facilitates good anatomical and functional outcomes in infectious canaliculitis.
