Immediate or delayed probing sufficient for congenital nasolacrimal duct obstruction
Two options are sufficient for treating bilateral nasolacrimal duct obstruction in infants, according to a study.Fifty-seven infants who had bilateral nasolacrimal duct obstruction were randomized in the multicenter study; 31 patients received immediate office-based probing within 2 weeks and 26 patients were observed for 6 months, using nonsurgical management with subsequent surgical facility-based probing for persistent cases.Patient age ranged between 6 months and less than 10 months.
