What is the reason for the total tears in eyes? Tears is a normal physiological phenomenon of human body, but if the tears are too much or too little, it indicates the existence of lesions. So what is the reason for the total tears in the eyes? Let's understand the reasons for the total tears in the eyes.
What reason is eye always lacrimal
Under normal circumstances, the lacrimal gland in the human eye structure can secrete a small amount of tears to maintain the lubrication of the eyeball and cornea and counteract the normal evaporation of tears. Because of the small amount of tears secreted at ordinary times, and they flow closely along the surface of the eyeball and the tiny space inside the eyelid, you won't feel the tears flowing. However, in the blink of an eye, the tears on the surface of the eyeball will be sucked into the sewer of tears - nasolacrimal duct. Lacrimal gland continuously secretes tears, nasolacrimal duct continuously excretes tears, so usually people will not shed tears.
1. Affected by external factors
Some patients with lacrimal gland by external stimulation, such as cold air, wind stimulation, reflective secretion, thus tears increased. And excessive tears can not be timely discharged by the lacrimal passage and flow out of the eyelid, resulting in the phenomenon of tears.
Treatment: This is purely a physiological phenomenon of tears, external stimuli such as removal, there will be no such symptoms, so no treatment.
2. Obstruction of tear discharge
Lacrimal secretion was normal, lacrimal passage was unobstructed, irrigation was unobstructed, but the orbicularis oculi relaxed, lacrimal pump function weakened or disappeared, which led to lacrimal discharge obstacles and tears.
Treatment: this case is functional dacryocystic mucosa, and the function of lacrimal drainage should be strengthened.
3. Chronic inflammation of the eye
If conjunctivitis, trachoma, trauma, foreign body, tumor and other reasons appear in the eyes, the lacrimal passage is narrow, the lacrimal passage is not completely blocked, the lacrimal drainage function is reduced, and the normal amount of tears can not completely flow into the nasal cavity and flow out of the eyelids, leading to tears.
Treatment: this kind of situation belongs to organic lacrimal overflow, even in the room will shed tears, should be timely to the hospital.
