Congenital lacrimal fistula: A major review
Аннотация: The purpose of this article is to review and summarize the etiopathogenesis, symptomatology, systemic associations, management, complications and clinical outcomes of congenital lacrimal fistulae. The authors performed an electronic database (PubMed, MEDLINE, EMBASE and Cochrane Library) search of all articles published in English on congenital lacrimal fistulae. Congenital subsets of patients from series of mixed lacrimal fistulae were included in the review. These articles were reviewed along with their relevant cross-references. Data reviewed included demographics, presentations, investigations, management, complications and outcomes. The prevalence of congenital lacrimal fistulae is reported to be around 1 in 2000 live births. They are frequently unilateral, although familial cases tend to be bilateral. Lacrimal and systemic anomalies have been associated with lacrimal fistulae. Exact etiopathogenesis is unknown but mostly believed to be an accessory out budding from the lacrimal drainage system during embryogenesis. Treatment is indicated when significant epiphora or discharge is present and is mostly achieved by various fistulectomy techniques with or without a dacryocystorhinostomy. Congenital lacrimal fistulae are a distinct clinical entity with unique features. Surgical management can be challenging and successful outcomes are usually achieved with widely accepted protocols.
