We report a case series of supernumerary puncta-canaliculi, a very rare congenital anomaly, and describe different clinical presentations and new treatment options. This is a retrospective chart review of patients diagnosed with supernumerary lacrimal puncta during the time between June 2015 and December 2021 at the Research Institute of Ophthalmology, Giza, Egypt. Four patients (two females and two males) with a mean presenting age of 54 ± 14 years had unilateral double puncta. Of those four patients, three had double puncta on the right lower eyelid whereas one had double puncta on the left upper and lower eyelid. In one of the three patients, the double puncta anomaly was an incidental finding, and the patient was asymptomatic. The other three patients had associated epiphora. All four patients were found to have patent double puncta with no mechanical obstruction. No surgical interventions were necessary for all four patients as one resolved after discontinuing the topical eye drops. Another patient resolved after the diagnostic probing of the puncta, and the third asymptomatic patient required no interventions. Epiphora in the fourth patient resolved with botulinum toxin injection in the lacrimal gland. Accessory lacrimal puncta can present in patients as an incidental asymptomatic finding or patients may present with epiphora. Patients who present with unilateral epiphora, dry eye, or canaliculitis should be carefully evaluated with a detailed slit-lamp examination using lid eversion to appreciate potentially easily missed supernumerary lacrimal puncta.
