Tears serve several key roles in the body and from keeping the eyes lubricated to help washing away any foreign substance, tears are also a component of the immune system and protects against infection. It is common to temporarily produce excess tears when a person is emotional, laughing, coughing or vomiting, but one of the most common reasons for Tearing Eyes is Dry Eye Syndrome i.e. extremely dry eyes can cause a person to produce tears. Some of the common signs and symptoms of Tearing Eyes include red eyes, vision loss, injured eye, chemicals in the eye, and bleeding from the eye, among others.
HOW IS TEARING EYES DIAGNOSED?
Sometimes the cause is easily identified - for example, infections, ectropion, entropion, and conjunctivitis. If there is no obvious cause revealed by a simple examination, further tests may be advised. These may depend on how bad the watering is, and how much it bothers you.If a drainage problem is suspected, an eye specialist may examine the tear drainage channels, under local anaesthetic. They may push a thin stick (probe) into the small channels (canaliculi) towards the tear sac to see if it is blocked. If the probe goes as far as the tear sac the fluid can be syringed into the tear duct to see if it comes out in the nose. Syringing may sometimes clear a blockage, but it may only give temporary relief. If there seems to be a blockage then a dye may be injected into the tear duct. An X-ray picture is then taken. You can see the dye in the duct on the X-ray film. It will show exactly where there is any obstruction or narrowing of the tear duct.Other scans - for example, a CT or MRI scan - may be undertaken in some cases.
HOW IS TEARING EYES TREATED?
If the watering eye is caused by infective conjunctivitis the doctor may prefer to wait for a week or so to see if the problem resolves itself without antibiotics.
DID YOU KNOW?
Tears are normally discharged through the tear ducts and then evaporate.
