Tear film instability is mostly considered dry eye, according to the different causes of the disease is divided into the lack of tears, evaporation of the strong type of two, through drugs, surgery and other methods can be treated to restore, not by themselves. 1. Insufficient secretion of lacrimal glands, or long-term eye fatigue caused by visual fatigue caused by the relative lack of tears, will cause the eyes to produce dryness, foreign body sensation, vision loss and other manifestations. Normal tears can be replaced by drops of artificial tears such as sodium vitrate, polyvinyl alcohol, etc. Surgical obstruction of the tear ducts can also be performed to reduce the loss of tears from the ocular surface. 2. Excessive evaporation from the ocular surface is usually due to inflammation of the leptomeningeal glands leading to a decrease in leptomeningeal gland secretion, which results in less lipid membrane components in the outermost layer of the tear film, making it difficult to maintain normal tear film function. For treatment, hot compresses, blepharoplasty massage therapy, and application of antibiotics such as levofloxacin are recommended. Tear film instability is treated differently depending on the cause of the disease, and usually does not recover on its own, but requires medication or even surgery, so it is recommended to go to the hospital for treatment.
