Nasal Lacrimal Duct Obstrucon What is overow tearing? Overow tearing, caused by a NLD (Nasal Lacrimal Duct) obstrucon is a congenital stenosis of the nasal lacrimal drainage system. It is a common cond ion in infants and babies. Approximately one in three infants are born with an overabundance of tears and mucus. It is also quite common for babi es’ eyelashes to sck together aer sleep, a situaon which can cause the eye(s) to become chronically infected. Epiphora is another name for overow tearing. How do tears drain from the eye? Tears drain from the eyes through two small openings called the upper and lower punctum, which are l ocated along the upper and lower eyelids near the nose. They then ow thro ugh the canaliculus into the lacrima l sac located under the skin on the side of the nose. From the sac, the tears are pumped by blinking acon of the lids into the tear ducts. These ducts go throug h the side bones of the nose and empty tears into the bac k of the nose. That’s why the nose runs when we cry. What causes overow tearing? Overow tearing is usually caused by the presence of a persistent membrane that blocks the lower end of the tear duct inside the nose. Normally, this membrane st retches or pops open at or before birth. In many infants, however, it is sll closed at birth, clogging the tear drainage sys tem. The blockage ma y open spontaneously in a few mon ths as the infant grows. Approxima tely 85% of blocked tear ducts open spon taneously by the age of 6 mont hs. How is overow tearing treated? Inially, the physician may recommend anbioc eye drops or ointment used once or twice daily, along with warm compresses and pressure or massage over the tear sac. To apply pressure, place a nger under the inner corner of the infant’s eye next to the nose, and roll the nger over the bony ridge while pressing down and in aga inst the bony side of the nose. This expresses mucu s and tears from the sac. Following pressure on th e sac, place an a nbioc in the ey e. Most tear block ages in infants will disap pear by six months of age. If the tearing persists, it may be necessa ry for the physician to open the tear ducts by probing and irrigaon. Usually this procedure is done in the opera ng room under general anesth ec.

Nasal Lacrimal Duct Obstrucon
What is overow tearing?
Overow tearing, caused by a NLD (Nasal Lacrimal Duct) obstrucon is a congenital stenosis of the nasal lacrimal
drainage system. It is a common condion in infants and babies. Approximately one in three infants are born wit
an overabundance of tears and mucus. It is also quite common for babies’ eyelashes to sck together aer sleep,
situaon which can cause the eye(s) to become chronically infected.
Epiphora is another name for overow tearing.
How do tears drain from the eye?
Tears drain from the eyes through two small openings called the upper and lower punctum, which are located alo
the upper and lower eyelids near the nose. They then ow through the canaliculus into the lacrimal sac located
under the skin on the side of the nose. From the sac, the tears are pumped by blinking acon of the lids into the
tear ducts. These ducts go through the side bones of the nose and empty tears into the back of the nose.
That’s why the nose runs when we cry.
What causes overow tearing?
Overow tearing is usually caused by the presence of a persistent membrane that blocks the lower end of the tea
duct inside the nose. Normally, this membrane stretches or pops open at or before birth. In many infants, howev
t is sll closed at birth, clogging the tear drainage system. The blockage may open spontaneously in a few monthas the infant grows. Approximately 85% of blocked tear ducts open spontaneously by the age of 6 months.
How is overow tearing treated?
nially, the physician may recommend anbioc eye drops or ointment used once or twice daily, along with warm
compresses and pressure or massage over the tear sac.
To apply pressure, place a nger under the inner corner of the infant’s eye next to the nose, and roll the nger ov
the bony ridge while pressing down and in against the bony side of the nose. This expresses mucus and tears from
the sac. Following pressure on the sac, place an anbioc in the eye. Most tear blockages in infants will disappea
by six months of age. If the tearing persists, it may be necessary for the physician to open the tear ducts by probi
and irrigaon. Usually this procedure is done in the operang room under general anesthec.

Nasal Lacrimal Duct Obstrucon
How is probing on the tear duct performed?
The probing is performed by using a thin, blunt metal wire, which is gently passed through the tear drainage syste
nto the nose to ensure that the pathway is open. Infants experience no pain aer probing, but some blood stain
of the tears or nasal secreon is common, and a discharge from the eye may be present for up to a week.
Anbiocs may be prescribed. Obstrucons can recur, and a repeated probing may be necessary.
f probing is not successful, plasc or silicone tubes can be placed in the drainage canal. This is a longer procedure
than probing. Occasionally, further surgery is needed to bypass the blocked tear duct and create a new opening
through the bone into the nose.
What complicaons can occur with treatment?
As with any surgical procedure, there is the possibility of infecon or bleeding. Scarring can re-obstruct the openi
requiring addional surgery. Chronic obstrucon can lead to infecons of the tear sac at any age.
