Question
How should congenital ductal obstruction be treated?
Answer
Congenital ductal obstruction occurs when the lower end of the nasolacrimal duct is sealed by a thin film or when the duct is blocked by epithelial fragments, preventing normal tear secretion from passing through the duct and resulting in persistent tear discharge. In most newborns, this film is intact at birth, but it usually breaks down between 3 to 4 weeks, restoring the tear duct’s patency. However, if the film does not rupture, it can affect the child’s appearance. Therefore, if a child is found to have a duct obstruction, it is essential to seek immediate medical attention at a regular ophthalmology hospital to avoid misdiagnosis and mistreatment, which could further worsen the condition.
