Eating tears
Introduction
Introduction Eating tears syndrome is also known as crocodile tear syndrome or Bogorad syndrome. 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. Crocodile tear syndrome is a common symptom of facial paralysis sequelae, and patients will cry when eating.

Diagnosis
Differential diagnosis
Several other tears:
Primary tearing: caused by the disease of the lacrimal gland itself, found in lacrimal gland inflammation, lacrimal gland cyst or lacrimal gland tumor. Neurological tearing: including tearing caused by stimulation of the trigeminal nerve, tearing caused by visual stimulation, tearing caused by stimulation of the facial nerve, sympathetic stimulation of tearing, and reflex tearing of taste. Symptomatic tearing: trichiasis stimulation, chronic inflammation, such as conjunctivitis, keratitis, blepharitis, etc., especially in the late trachoma, is a common cause of tearing in the elderly. In addition, it can also be seen in patients with hyperthyroidism and patients with Parkinson's disease.
Older people have more tears: Older friends often complain that "tears" are like "ghosts", and they meet unexpectedly and linger. Going out for morning exercises is "filled with tears"; when reading or talking, there is no reason for "tears"; when riding a bicycle, suddenly "tears are tearful" and dangerous. Some elderly friends continue to wipe their eyes because of repeated tears, which eventually leads to red, swollen, painful, and even erosive eyelids. In order to eliminate the symptoms of tearing, some elderly friends purchased various eye drops, including hormonal eye drops, and the results were not satisfactory. In fact, these worries and fears are not necessary.
Tears in the wind: There is no redness and swelling in the eyes, and there is no tears. However, when it is stimulated by the wind, it causes tears. When there is no wind, it is more obvious than winter or spring. The tears are thin and have no heat. Corneal foreign body clinical manifestations of foreign body sensation, photophobia and tearing are prominent, 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. Tear overflow is caused by the leakage of the lacrimal passage when the tear secretion is normal, causing the tear 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.
