[Research progress of diagnosis in neuropathic corneal pain].

The cornea is the most innervated tissue in the human body. Neuropathic pain occurring in the cornea has gradually attracted the attention of ophthalmologists. However, the definition and pathogenesis of neuropathic corneal pain (NCP) have not been clearly defined, making the diagnosis and treatment of the disease extremely challenging. In recent years, with the application of ocular surface pain assessment scales, in vivo confocal microscopy and functional magnetic resonance imaging in the clinical assessment of NCP, the diagnostic methods of NCP have been enriched. This paper reviewed the research progress of diagnostic methods of NCP, with a view to improving the ophthalmologists' understanding of NCP and promoting the application of these technologies in the diagnosis of NCP.角膜是人体最敏感、神经分布最丰富的组织，角膜神经痛已逐渐得到眼科医师的关注，但角膜神经痛的定义、发病机制尚未明确，使得该病的诊断和治疗极具挑战性。近年来，随着眼表疼痛评估量表、活体共聚焦显微镜和功能性磁共振成像逐步应用于角膜神经痛的临床评估中，角膜神经痛的诊断方法得以丰富。本文针对近年来角膜神经痛的诊断方法学研究进展进行综述，以期提升国内广大眼科医师对角膜神经痛的认识，促进这些技术在我国角膜神经痛诊断领域中的应用。.
