If NLDO recurs after dilation and irrigation, what is the likely next step?

• A. Surgery
• B. Repeat dilation and irrigation
• C. Observation
• D. Antibiotics only

Answer: (A)

When nasolacrimal duct obstruction recurs after dilation and irrigation, the blockage persists despite nonsurgical management, so a definitive surgical solution is indicated. The next step is surgical dacryocystorhinostomy, which creates a new drainage route from the lacrimal sac directly into the nasal cavity, bypassing the obstructed duct. This approach addresses the underlying blockage and has high success rates, making it the standard option after failed initial management. Repeating dilation and irrigation is less likely to succeed after a recurrence, observation leaves persistent symptoms and potential infections, and antibiotics alone don’t resolve the mechanical obstruction. Surgical options include external or endoscopic dacryocystorhinostomy, both effective choices depending on patient anatomy and surgeon preference.
