 [ Symptoms ] our 15 month old is having her tear duct probed only one eye weeps but the dr says that both eyes should be done  please advise [ Disease ] since the child will be briefly under anesthesia it would seem logical to just probe both naso lacrimal ducts at the same time the procedure is fast and easy and really poses no additional risk to the child a child with naso lacrimal duct obstruction on one side may eventually develop the problem on both sides by probing both sides you could head off a future obstruction
