A 4 month old with congenital nasolacrimal duct obstruction (CNLDO) had several episodes of dacryocystitis and is currently hospitalized for cellulitis. What is the appropriate follow up?

• A. Surgical referral for potential tear duct probing
• B. Continued frequent massage over the lacrimal duct
• C. Daily use of an ophthalmic antibiotic ointment
• D. Oral antibiotic prophylaxis

Answer: (C)

In congenital nasolacrimal duct obstruction, the goal is to prevent infections while planning definitive management if needed. When an infant has had recurrent infections and is hospitalized for cellulitis, the best interim follow-up is daily topical antibiotic ointment to provide local prophylaxis and reduce the chance of new infection between episodes. This approach minimizes systemic exposure and buys time until a surgical decision about tear duct probing is considered later, typically if infections persist or recur despite conservative measures. Surgical probing is not the immediate follow-up because the infant is still very young and needs stabilization; probing is usually considered after stabilization and/or once recurrent infections persist beyond several months. Continuing massage is beneficial but unlikely to prevent recurrence in the setting of recurrent dacryocystitis with cellulitis. Oral antibiotic prophylaxis is not preferred due to systemic exposure and potential side effects when topical prophylaxis is adequate.
