Prevalence and surgical outcome of congenital lacrimal fistulas in Guatemala
Journal Title: Ophthalmology and Vision Science - Year 2016, Vol 1, Issue 1
Abstract
Background: The purpose of this study was to review the prevalence, surgical techniques and outcome of congenital lacrimal fistulas performed over a 10-year period in Rodolfo Robles hospital, in Guatemala. Method: The medical records of all patients presenting congenital lacrimal fistulas between December 2006 and November 2016 were collected and analyzed. Recorded data included demographic features, associated abnormalities of the lacrimal outflow pathway, type of surgical intervention, outcome and complications. Patients with acquired lacrimal fistulas were excluded. Results: Twenty-nine eyes out of twenty-eight patients that underwent surgical treatment for correcting symptomatic congenital lacrimal fistulas were identified. Sixteen patients (57%) were males and twelve patients (43%) were females. The predominant symptom was epiphora. The most common site of the fistulas was the inferior medial canthal area. This area was connected to the lacrimal sac in 90% of the cases and to the common canaliculus in 10%. The functional success rate was 96.5% after surgical treatment. Conclusion: Congenital lacrimal fistulas may be successfully treated excising the anomalous tissue (fistulectomy) and managing the lacrimal pathway according to the age of the patient and the presence or absence of obstruction.
