Insights
Pediatric acquired lacrimal drainage apparatus (LDA) obstruction is rare but treatable. Common causes include infections and trauma, with surgical interventions yielding positive outcomes.
Area of Science:
- Ophthalmology
- Pediatric Medicine
Background:
- Pediatric acquired lacrimal drainage apparatus (LDA) obstruction is less common than congenital cases.
- Etiology and treatment outcomes for acquired LDA obstruction in children require further definition.
Purpose of the Study:
- To investigate the causes of acquired LDA obstruction in children.
- To describe the management strategies and outcomes for this condition.
Main Methods:
- Retrospective review of medical records for patients 16 years or younger.
- Analysis of patients presenting with acquired epiphora.
Main Results:
- 31 pediatric patients (mean age 10.9 years) were included.
- Key causes identified: keratoconjunctivitis, herpes simplex blepharokeratoconjunctivitis, and trauma.
- Management involved silicone tube intubation, dacryocystorhinostomy, and lacrimal bypass tubes.
Conclusions:
- Acquired LDA obstruction should be suspected in children with persistent epiphora.
- Surgical management approaches are comparable to those used in adult patients.
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.
