Summary

A rare case of pediatric nasolacrimal duct obstruction caused by dacryoliths was successfully treated surgically. This highlights the importance of considering canaliculitis in persistent cases of blocked tear ducts in children.

Area of Science:

  • Ophthalmology
  • Pediatric Otolaryngology

Background:

  • Nasolacrimal duct obstruction (NLDO) is common in children, often resolving with conservative management.
  • Idiopathic thrombocytopenic purpura (ITP) is an autoimmune condition affecting platelet counts.
  • Partial NLDO unresponsive to standard treatments warrants further investigation.

Observation:

  • A 5-year-old girl with a history of ITP presented with persistent partial NLDO.
  • Previous treatments including probing, irrigation, and intubation failed to resolve the obstruction.
  • Surgical exploration identified canaliculitis with dacryolith formation in the inferior canalicular system.

Findings:

  • Canaliculitis with dacryoliths, though rare in children, was the cause of obstruction.
  • Surgical intervention involving punctoplasty and dacryolith removal led to complete symptom resolution.

  • Histopathological examination confirmed the presence of dacryoliths.

    • Implications:

    • This case underscores the necessity of including canaliculitis and dacryolith formation in the differential diagnosis for chronic or recurrent pediatric NLDO.
    • Early surgical intervention can be effective in resolving complex cases of pediatric NLDO.
    • Further research may elucidate the underlying mechanisms contributing to dacryolith formation in pediatric patients.
