Tears in the wind

Introduction There is no redness and swelling in the eyes, and there is no tearing. However, when it is stimulated by the wind, it causes tearing. When there is no wind, it is more severe than winter or spring. The tears are thin and have no heat. Some people are more sensitive to cold stimuli. When the eyes are stimulated by cold air and the secretion function of the lacrimal gland is enhanced, more tears are secreted. At the same time, the lacrimal canal is stimulated by cold wind, and the sphincter of the eye undergoes spasmodic contraction. Thus, the tear tube that is already thinner can not discharge too much tears immediately, and tearing occurs. In fact, this phenomenon is a protective physiological response of the lacrimal gland to cold stimulation, and the functional function of the wind and tears.

Cause

Cause:

There are many reasons for the wind and tears, including the problems of the body, and of course the weather. First of all, let's take a brief look at the internal factors: There are two main types of internal causes of tears in the wind, one is "virtual", that is, the liver and kidney are both imaginary, showing tears when there is wind, but the eyes are not red and not painful, tears are thin There is no heat when flowing; the other is "hot", that is, wind-heat type, mainly characterized by turbid tears, a feeling of heat, and redness and swelling of the eyes.

The above is the internal factor of the wind and tears. In fact, the external environmental factors are also the main cause of the wind and tears. This is mainly reflected in changes in temperature, humidity and wind in the weather. The surface of the human eye has a lubricating film, that is, a tear film. Under normal circumstances, the blinking action can evenly apply tears on the film to ensure a clear and comfortable vision. If the temperature is too low, the eyeball will be strongly stimulated by the cold wind, which will directly cause the lacrimal gland to be blocked. At the same time, a large amount of dust in the wind will block the lacrimal gland and hinder the secretion of tears. Another reason for the wind and tears is drying. In winter, even in the Jiangnan waters, it will dry out in other seasons, while people in the north will have a deeper experience of drying in winter.

Diagnosis: There is no redness and swelling in the plain eye, and there is no tearing. However, when it is stimulated by the wind, it causes tearing. When there is no wind, it is more severe than winter or spring. The tears are thin and have no heat.

Chinese medicine believes that: this disease is mostly caused by liver and kidney deficiency, loss of blood, attracting external wind, but also caused by lacrimal diseases caused by nasal diseases. The witness sees the wind blowing tears out of the bar, the life is wiped out, the winter tears, the summer tears less, or the four seasons are often divided into tears, if the liver and kidney are both effective to nourish the liver and kidney, with Zuogui pill addition and subtraction. If the lacrimal duct is obstructed, it can be treated with hemorrhage or surgery.

Differential diagnosis

Differential diagnosis:

Eating tears: Taste reflex tears are also called "crocodile tears." "Crocodile tears" patients have tears when they see food. Divided into congenital and acquired. Congenital "crocodile tears" due to dysplasia or birth injury, acquired congenital facial nerve sputum recovery when the parotid nerves into the lacrimal gland, resulting in the secretion of saliva at the same time secretion of tears.

Photophobia and tearing: photophobia and tearing are prominent, and foreign body sensation is a clinical manifestation of corneal foreign body. Foreign bodies entering the pupil area can cause visual impairment. Corneal foreign body refers to an ophthalmologic emergency caused by accidental entry of foreign bodies such as gray foam, small insects, metal fragments and sawdust into the cornea of the eye. Foreign body sensation, photophobia and tearing are prominent, and foreign bodies entering the pupil area can cause visual impairment.

Tear overflow: In the case of normal tear secretion, the tear channel excretion disorder causes tears to overflow through the rim. Increased in the wind. Tears are the main symptoms of lacrimal disease. Lacrimal disease is a common eye disease that patients feel extremely painful. Tears should be distinguished from tearing caused by excessive secretion of reflex lacrimal glands.
