Three different types of congenital lacrimal sac fistulas

Three different symptoms in 4 patients with congenital lacrimal sac fistulas are presented. The first symptom was epiphora since birth, the second symptom was infection of the lower eyelid, and the third symptom was tearing from the eye in a 76-year-old patient. This patient had nasolacrimal obstruction at the canal level and no symptoms of congenital lacrimal sac fistula. She had undergone excision, including dacryocystorhinostomy. Three of the 4 patients underwent excision of the fistulous tract. The fistula originated from the lacrimal sac in all patients. Symptomatic congenital lacrimal sac fistulas can be treated successfully with excision alone or with excision and dacryocystorhinostomy in cases of nasolacrimal obstruction.
