Watering Eyes and Lacrimation


Eyes | Ophthalmology | Watering Eyes and Lacrimation (Symptom)


Description

Watery eyes (eyes flowing) is when the tears are produced without any obvious explanation. The medical name is epiphora. It may affect one or both eyes. The glands constantly produce tears to keep eyes moist and lubricated. The lacrimal gland is a small gland situated above and outside of each eye.

Over time, the tear duct can become low, often due to inflammation (swelling). If tear ducts are blocked or narrowed, the tears will be able to escape and remain in the lacrimal sac. Lacrimal sack can become infected and the eye will produce a sticky liquid.

Occasionally, the narrow drainage channels on the inside of the eye may become blocked. This may be due to inflammation. If the eyes are irritated, they will automatically produce extra tears to wash away the irritation.

Causes

Irritants that can cause more tears to be produced include: chemical irritants such as onions or smoke; eye infection such as infectious conjunctivitis; inflammation caused by an allergy, as in allergic conjunctivitis, eye injuries, such as a scratch or a piece of grit that is deposited in the eye, or an increase in active genes. A watery eyes can be caused also when the lower eyelid turns outwards away from. If this happens, your tears are not flowing properly. If tears were a normal fat content (fat), they are not able to be spread evenly across the eye. This can result in portions of dry eye, which become painful and cause more tears to be produced.
