Taurine eye drops are not anti-inflammatory drugs. The main active ingredient is taurine, a sulfur-containing amino acid, which is the main amino acid in the mature retina. This drug can promote the growth and development of the retina and relieve the spasm of the ciliary muscle. Taurine is also able to combine with reducing sugars in the atrial fluid and vitreous humor to protect proteins in the vitreous humor from glycation and oxidation. This drug is mainly used clinically as an adjunct to the treatment of acute and chronic conjunctivitis. When using this drug, care should be taken to avoid contact of the tube mouth with the hands and eyes when using eye drops and to pay attention to personal hygiene. If eye congestion, itching or edema occurs after use, it should be discontinued promptly and a hospital visit should be made. In conclusion, Taurine eye drops are not anti-inflammatory drugs, but a sulfur-containing amino acid that promotes retinal growth and development and relieves ciliary muscle spasm.
