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.
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.
