Insights
Congenital nasolacrimal duct obstruction (CNLDO) in children requires careful treatment consideration due to potential complications and amblyopia risk. A graduated, individualized approach balancing conservative and invasive methods is recommended.
Area of Science:
- Ophthalmology
- Pediatric Medicine
Background:
- Congenital nasolacrimal duct obstruction (CNLDO) is a common pediatric ophthalmology issue.
- Persistent Hasner's membrane causes most CNLDO cases, posing risks of complications and potential amblyopia.
Purpose of the Study:
- To review therapeutic options for CNLDO.
- To emphasize individualized treatment based on clinical factors and spontaneous recovery rates.
Main Methods:
- Literature review of conservative and invasive treatment modalities for CNLDO.
- Discussion of graduated treatment concepts including digital compression, probing, intubation, dacryoendoscopy, balloon dacryoplasty, and dacryocystorhinostomy.
Main Results:
- CNLDO has high spontaneous recovery rates in early childhood, necessitating careful deliberation before invasive interventions.
- Conservative digital compression is the initial approach; invasive treatments are reserved for complications like dacryocystitis or amblyopia.
Conclusions:
- A graduated, individualized treatment strategy for CNLDO is essential.
- Treatment choices depend on factors like spontaneous recovery, complications, and potential for amblyopia.
Abstract:
Unresolved epiphora in childhood is one of the most frequent issues in paediatric ophthalmology. In this context, connatal nasolacrimal duct obstruction (CNLDO) is the most important differential diagnosis and the condition is caused by a persistent Hasner's membrane in most cases. As there is a risk of complications, treatment should be considered. Therapeutic options include conservative and invasive approaches. As CNLDO is associated with high spontaneous recovery rates during the first years of life, the indication for invasive interventions must be carefully deliberated in that period. Conservative treatment with digital compression of the lacrimal sac should be performed whenever CNLDO is suspected. Invasive treatment is recommended in case of complications such as acute dacryocystitis or recurrent ascending infections. Furthermore, CNLDO seems to be amblyogenic. In addition to probing and syringing, temporary intubation of the lacrimal duct is possible. Further transcanalicular approaches include dacryoendoscopy or balloon dacryoplasty. Dacryocystorhinostomy should be reserved for special indications, although it has a low rate of complications and treatment is successful in 90 % of cases. The available treatment approaches can be integrated into a graduated treatment concept, which is influenced by many factors and should therefore be individualised.
