Tis article reports a case of a middle-aged male patient who visited the Department of Neurosurgery of our hospital due to headache and lef hearing loss. He was diagnosed with lef trigeminal schwannoma by imaging examination and abnormal blood routine before surgery. During chemotherapy and paralytic keratitis (neurotrophic keratitis, NK), can be seen in the lower part of the corneal center of the epithelium and the prestromal layer of round gray and white turbidities, jelly like, afer local drug treatment improved, but residual corneal stromal white turbidities. Due to the lack of full understanding of NK in clinic at the present stage, diagnosis and treatment is easy to be delayed. In addition, the NK patient reported in this paper was easily misdiagnosed as bacterial keratitis complicated by chemotherapy due to his history of chemotherapy and related signs during treatment. Tis paper analyzed the characteristics of keratopathy and briefy reviewed the clinical characteristics, diferential diagnosis and treatment of NK, in order to identify and treat these patients in early clinical stage, restore the optical characteristics of cornea and maintain good visual experience.
Figure 2 The conjunctiva of the left eye was obviously hyperemia, and the corneal epithelium and anterior stromal layer were of uniform depth, gray and white turbidity, and were jelly-like
