What is excessive tearing?
Excessive tearing is a condition in which tears spill out of
your eyes even though you are not crying. Excessive tearing
is also called watering eye or epiphora.
How does it occur?
Tears normally drain into small holes in the inner corner of
the upper and lower eyelids (the puncta) through a drainage
system into the nose. When there is too much tearing for
this system to handle or not enough drainage, there can be
an overflow and tearing. There can be many possible causes
for too much tearing. They include:
- Dry eye syndrome and other irritations. Dry eye syndrome
is the most common cause of excessive tearing. It happens
when the normal, lubricating tears that keep your eye
moist are too few or dry out too quickly. When your eye
is irritated by the dryness, your eye starts making too
many reflex tears. These reflex tears do not keep your
eyes moist, however. Other types of irritation, such as
infection, allergies, or eyelashes rubbing against the
eye, can also cause reflex tears.
- Problem with the drainage system. Scarring due to
infection, certain medicines, or injury may block the
drains for tears and cause an overflow.
Some babies are born with a blockage in the drainage
system. This will cause tearing and discharge for many
months, but it often gets better as children get older.
Sometimes the eyelids are turned in such a way that the
small draining holes on the eyelids do not face the right
way. This can cause a tear problem as well.
How is it diagnosed?
Your healthcare provider will do a complete eye exam,
looking for causes of the tears and checking the drainage
system. Sometimes a special dye or shot of saline solution
is put into the drainage system to check for problems.
How is it treated?
The tearing can be reduced with treatment of the underlying
cause. For example, if your eye is watery because of an
infection, treatment of the infection will reduce the
tearing. If you have dry eye syndrome, you may need to use
artificial tears (eyedrops) or warm, moist cloths
(compresses) on your eyes to help keep your eyes moist. If
the drainage system is blocked, or the position of your
eyelids is causing the tearing, surgery may be needed to
correct the problem.
How can I take care of myself?
You may need to use warm compresses and eyedrops for a long
period of time. See your eye doctor if you have increased
pain or decreased vision.
