Watery eyes can be very annoying, especially if you frequently or constantly affected. The most common cause of watery eyes is a dry eye. If the tear production in quantity or composition is not sufficient to be able to carry out the protective task to the eye, one speaks of dry eye. Paradoxically, watery eyes can thus be caused plenty of dry eyes. This is the case when the quality of the tear film is not good. The tear film covering the eye surface and is composed of a fatty layer, an aqueous layer and a slimy layer.

Tearing eyes: definition

The definition of watery eyes is: a patient usually annoying tearing of one or both ogen.¹ the cause must be sought often in an impaired drainage technique of tears. An increased flow of lacrimal fluid as a result of irritation of the anterior eye segment through, for example, a foreign body in the eye, or inflammation of the eye, is also a common cause. The most common cause of a weeping eye is paradoxically a dry eye, the quality of the tear film is not good is.² This allows more tears needed to keep the eye moist.

The production and drainage of tears

The small glands in the white part of the eye, the mucous membrane, making the normal tears. The lacrimal glands, which lie above the eyeball, lacrimal fluid separates out of irritation or strong emotion leaving more tear fluid. The normal production of tears have called basal secretion and the production of extra tears is called reflex or response tears tears by the lacrimal gland. The latter kind of tears lubricate the eye no or not enough.
Normally, tear fluid collects in the nasal corner of the eye, i.e., the corner of the eye located at the nose. These two small openings called tear points. By the blinking movement of the eyes there is a suction effect of the tear point and through a tear duct, the tears come into the lacrimal sac, after which it flows into the nasal cavity through the nasal lacrimal duct. This explains why one should weep after blow. Not all tears are discharged via this ingenious drainage system. A part of the tears will disappear by evaporation. It has been estimated from about 10 to 20%.

The tear film

Every time a person blinks, and that on average every 20 to 30 seconds, the tears in a thin layer is spread evenly over the eye surface. This is called the "tear film. Tear fluid has as main function to keep the eye moist. Additionally tears washes away dust and dirt. Tears also contain an antibacterial component.
The tear film is composed of three components:
  • The outermost layer: an oily layer, which is produced by the meibomian glands. This oil-like layer prevents the tear fluid evaporates too quickly.
  • The middle layer: an aqueous layer which is produced by the glands in the mucosa, and by the lacrimal gland. This layer has the task to clean the eye wash dirt and dust. Also, this layer has an anti-bacterial function. Furthermore, it provides the outer horny layer of oxygen.
  • The inner layer: a slimy layer, originating from small glands in the conjunctiva of the eye. This layer should ensure that the aqueous layer is evenly distributed over the eye and can adhere well to the surface. It also serves as the wetting of the eye.

Possible causes of watery eyes

Tearing eyes can have many different causes. With watery eyes, there is always talk of an imbalance between production and drainage of tears. One or more of the following three factors may be in play:
Watery eyes, excessive tear production due to reflex tears or pseudo tears
Reflex tears means that the tear production increases in eye irritation. A source of irritation is a foreign body in the eye, a hair that rub against the eye, and inflammations of the eye or the eyelid.
Pseudo- or neptranen is a condition where the eye is weeping because it is too dry. When the quality of the tear film is disturbed, the cornea dries out and through the nerves there is a call at the lachrymal gland in order to produce more tears. This causes an overproduction of tears, tears often qualitatively still not enough so the irritation persists for life. They are not nurturing tears, lubricating eye irritation and did not therefore persists. Treatment with tear substitutes can provide relief of symptoms and break this vicious circle.
Tearing eyes: a dysfunction of the lacrimal pump
The pumping action of the eye can be disrupted by various causes, such as a weakened eyelid, which is particularly prevalent in older people. As a result, are the eyelid and the lacrimal point must not fit snugly against the eye, with the result that the tears do not go well at the tear point. Also cause muscle paralysis, scar and other abnormalities, can a ceding eyelid.
Tearing eyes: deviations from the drainage of tears
There is a blockage or narrowing in the drain system may be provided by, for example, a congenital abnormality, an inflammation, a blocked nasal lacrimal duct or an accident, which leads to watery eyes. It is also possible that the tear points do not sit in the correct place, or are clogged or narrowed.
Tears Ende eyes in children
In babies from 0 to 1 year, watery eyes fairly common. In that case, the entrance of the nasal lacrimal duct into the nose has not yet opened. The eye that weeps and is often dirty. This often goes away.

Treatment watery eyes

Treatment depends on the cause. Irritation at the source of irritation is treated or removed, for example, remove hairs. Dry eyes can be treated by removing the cause and if that fails, the source of irritation is removed as much as possible. This can be done by, for example, by tear substitutes, which may consist of artificial tears.
An eyelid surgery can be performed under local anesthesia when the tear points and / or the lid does not fit properly. When an abnormality in the exhaust system, there could possibly be done traanwegoperatie. One tries thereby to lift the blockage. The procedure depends on the site of blockage. When the tear ducts are blocked and can not be corrected, may offer a solution traanwegprothese, whereby between the corner of the eye and the nose is placed a tiny tube.
In children, opens the entrance to the nasal tear duct in many cases automatically, when the child is between nine months to a year old. Gently massage can help the lacrimal sac. Minor surgery may be necessary to open the passage, when the problem persists.
