Acquired lacrimal drainage apparatus obstruction in children.

BACKGROUND

Pediatric acquired lacrimal drainage apparatus (LDA) obstruction is much rarer than congenital LDA obstruction. Its etiology and treatment outcomes have not been well defined. Our aim was to examine the etiology and management of acquired LDA obstruction in children and report the results of its management.

METHODS

We retrospectively reviewed the medical records of patients ≤16 years of age who presented with acquired epiphora to investigate the causes and describe the management of this condition.

RESULTS

A total of 31 patients (16 males [52%]) were included. Mean age of patients was 10.9 years (range, 3-16). The main causes of acquired LDA obstruction were keratoconjunctivitis, herpes simplex blepharokeratoconjunctivitis, and trauma. Silicone tube intubation, endonasal or external dacryocystorhinostomy, and the insertion of lacrimal bypass tubes were the mainstays of management.

CONCLUSIONS

It is important to suspect acquired LDA obstruction in children with acquired, persistent epiphora. Surgical management is similar to that in adults.
