There are many causes of eye tearing, such as emotional changes, excessive eye use, foreign body irritation and other physiological factors, which generally do not need to be treated, but there may also be pathological factors, such as trachoma, impingement, entropion, eye trauma, inflammation of the eye appendage, lacrimal gland lesions, narrow or blocked tear ducts, rhinitis, etc., which need to be treated according to the specific cause. 1, physiological factors 1, emotional changes: such as sadness, depression or stress, may lead to tears, you can listen to light music or communicate with others to divert attention, for no reason tears, along with no interest in other things, may be due to mental illness problems, need to promptly consult a doctor; 2, excessive eye: when work, study for a long time or stay up late, long-term use of the eyes lead to eye Fatigue, will also produce tears, at this time can be appropriate rest, look into the distance, hot compress eyes, etc., will generally improve; 3, foreign body stimulation: such as eyelashes, dust, flying insects and other foreign body stimulation lead to eye tears, is a normal physiological phenomenon, do not need to over-treatment, stimulation disappeared, generally will not flow again tears. Second, pathological factors 1, trachoma: trachoma is a chronic infectious conjunctival keratitis caused by Chlamydia trachomatis infection, mainly manifested as photophobia, lacrimation, foreign body sensation, more secretions. Trachoma can be treated with rifampicin eye drops, phthalidone eye drops, neomycin eye drops, etc. You can also choose antibiotic ointment. 2. Ingrown eyelashes: Ingrown eyelashes are caused by the growth of eyelash follicles in the wrong direction, resulting in eyelashes that irritate the eyes and produce tearing, accompanied by foreign body sensation and pain. Therefore, when conservative treatment does not work, you can choose to treat it with freezing, laser, radiofrequency and eyelash follicle removal surgery. Entropion can also lead to tearing of the eyes and may be caused by an abnormal curl of the lid margin toward the eyeball. For congenital entropion, it can be left untreated and may improve with age; if not, surgical treatment such as fornix lid skin threading may be required; for the elderly, local injection of botulinum toxin or surgical removal of excess loose skin and cutting off some of the orbicularis muscle fibers; for scarring entropion, lid wedge resection For more serious eye trauma, immediate medical attention is required. 5. Inflammation of the ocular appendages: When inflammation of the ocular appendages occurs, such as conjunctivitis, keratitis, lacrimal sacculitis, and blepharitis. Due to bacterial or viral infection, resulting in inflammation of the eye structure, under the stimulation of inflammatory factors, there will be unconscious tears, using antibiotic eye ointment such as levofloxacin, tobramycin eye drops, ribavirin eye drops, etc., when the inflammation is eliminated, the symptoms of tears will improve; 6, lacrimal gland lesions: excessive tear secretion can also be secondary to the stimulation of physical and chemical factors or emotional factors, treatment to the main reason. Certain systemic diseases such as Parkinson’s disease and facial nerve palsy can be secondary to tear secretion. Patients with Parkinson’s disease need long-term control with levodopa, bromocriptine and other drugs, the symptoms of tear flow will be reduced when the condition is stable; patients with facial nerve palsy need to protect the conjunctiva, eye shields to cover, drops of artificial tears and other eye drops to relieve the discomfort caused by irritation to the eyes; 7, tear duct narrowing or blockage: seen in congenital malformations, inflammation, tumors and other factors that cause structural or functional insufficiency of the tear duct, resulting in tears can not be properly excretion, tear overflow occurs. You can use massage, probe expansion of the tear duct, etc. The tear duct is completely narrowed and requires surgical treatment, such as laser lacrimal ductoplasty or tear sac nasal anastomosis, etc.; 8, rhinitis: when suffering from rhinitis, sinusitis and other nasal diseases, may also produce tears, because the nasal cavity and the eyes are connected, if the nasal inflammation is more serious, may induce tears, need to go to the ear, nose and throat specialist for consultation, clarify the type of rhinitis, and The treatment should be targeted. For frequent unexplained excessive tearing, after excluding physiological problems, determine what kind of pathological disease is causing it and take treatment for the cause. Secondary excessive tearing requires active treatment of the original disease, and the symptoms of excessive tearing will improve when it gets better.
