Purpose: Acquired nasolacrimal system obstruction accounts for a relatively small number of cases of this condition in children. Its aetiology has not been well deﬁned. Similarly, outcomes of its man- agement have not been widely elaborated. Our aim was to examine the aetiology and management of acquired nasolacrimal system obstruction in chil- dren in our centre and outline the results of its management.
Methods: We retrospectively reviewed the medical records of patients aged 16 years or below present- ing with epiphora who, without congenital nasola- crimal duct obstruction had acquired nasolacrimal system obstruction.
Results: Twenty-seven patients aged 16 years or below with acquired nasolacrimal system obstruc- tion were identiﬁed. 14 (53.8%) were male and 13 (14.2%) female. Their mean age was 10.1 years with range 3-16 years. The main causes of acquired nasolacrimal system obstruction were epidemic ker- atoconjunctivitis, herpetic blepharitis and trauma. Silicone tube intubation, endonasal or external dacryocystorhinostomy were the mainstays of management.
Conclusions: It is important to suspect acquired nasolacrimal system obstruction in children with persistent epiphora. We describe the complete range of causes and treatment modalities for paediatric epiphora secondary to acquired nasolacrimal system obstruction. Surgical challenges in the paediatric age group are distinct but excellent outcomes are achievable.
