[Consensus of experts on diagnosis and treatment of neurotrophic keratitis in China (2021)].

Neurotrophic keratitis is a degenerative disease of the cornea caused by impairment in the trigeminal nerve, which can lead to dry eyes, corneal epithelial defects and corneal ulcers. The common causes include herpes virus infection, craniocerebral and ophthalmic surgery injury, and diabetes. Due to the reduced or lack of corneal sensitivity, patients' symptoms are mild, while severe corneal stroma melting or even perforation may occur. And the conventional symptomatic treatment is not effective. In view of the current lack of clinical understanding of this disease, there are a large number of problems of misdiagnosis and mistreatment. To improve the level of diagnosis and treatment, the consensus of experts on diagnosis and treatment of neurotrophic keratitis, which can be used as a reference for ophthalmologists in clinical work, is formulated by the Cornea Group of Chinese Ophthalmological Society.
