Dry eye, also known as dry eye or keratoconjunctivitis xerosis, is a common eye disease, mainly due to insufficient tear secretion or excessive evaporation, causing eye discomfort, such as eye fatigue, foreign body sensation or dryness. Eye fatigue can lead to headache, so eye drops or other methods should be used to treat dry eye to relieve discomfort and symptoms. The treatment of dry eye mainly includes the following methods: firstly, artificial tears, such as sodium hyaluronate, polyvinyl alcohol, tears, Siran and other eye drops commonly used in the market, and eye-nourishing gels, such as deproteinized calf blood gel and vitamin A palmitate gel, can be used. Secondly, besides eye drops, hot compress and fumigation can also relieve dry eye. Severe dry eye can cause corneal epithelial shedding, and eye drops for repairing cornea, such as Befushu eye drops, also called recombinant bovine basic fibroblast growth factor eye drops, can also be used. There is also meibomian gland dysfunction, which can be massaged and treated with antibiotic eye ointment. In short, in order to alleviate the symptoms of dry eye, comprehensive treatment can be done. After the relief of dry eye, symptoms such as eye fatigue, dryness and foreign body sensation will disappear. To get dry eye, we should first do some related tests in the hospital, such as tear secretion test, basic tear secretion, tear film rupture time, meibomian gland dysfunction and so on. Secondly, judging the degree of dry eye by these tests, mild dry eye can be treated and relieved by dropping artificial tears, and it is best to use artificial tears without preservatives, which can be used for a long time and can relieve dry eye symptoms. If it is moderate or severe dry eye, we can consider doing punctate embolization to prolong the time of tears staying on the eye surface, lubricate the eyes and relieve dryness. At the same time, the existence of dry eye should also take into account the general condition. If you have Sjogren's syndrome all over your body, you need to go to the Rheumatology Immunology Department for relevant examination and treatment.
