A Comparison of Treatment Approaches for Bilateral Congenital Nasolacrimal Duct Obstruction – Corrected Proof
Purpose: To compare the clinical outcomes of two treatment approaches for bilateral nasolacrimal duct obstruction (NLDO) in infancy.Design: Multicenter, randomized clinical trial.Methods: We studied 57 infants between the ages of 6 and <10 months who had bilateral NLDO. Participants were randomized to receive either (1) immediate office-based probing within two weeks (n = 31) or (2) 6 months of observation and nonsurgical management followed by surgical facility-based probing for unresolved cases (n = 26). Treatment success was defined as the absence of clinical signs of NLDO (epiphora, increased tear lake, mucous discharge) in both eyes on masked examination at 18 months of age.Results: In the (Read more...)
