The cornea is unique because of its complete avascularity. Corneal neovascularization (CNV) can result from a variety of etiologies including contact lens wear; corneal infections; and ocular surface diseases due to inflammation, chemical injury, and limbal stem cell deficiency. Management is focused primarily on the etiology and pathophysiology causing the CNV and involves medical and surgical options. Because inflammation is a key factor in the pathophysiology of CNV, corticosteroids and other anti-inflammatory medications remain the mainstay of treatment. Anti-VEGF therapies are gaining popularity to prevent CNV in a number of etiologies. Surgical options including vessel occlusion and ocular surface reconstruction are other options depending on etiology and response to medical therapy. Future therapies should provide more effective treatment options for the management of CNV.
角膜的独特之处在于其完全无血管。角膜新生血管(CNV)可由多种病因引起,包括隐形眼镜佩戴、角膜感染和眼表疾病(炎症、化学伤和角膜缘干细胞缺乏等)。治疗主要针对引起 CNV 的病因和病理生理学,包括药物和手术治疗。由于炎症是 CNV 病理生理学的关键因素,皮质类固醇和其他抗炎药物仍然是治疗的主要方法。抗血管内皮生长因子(VEGF)治疗在多种病因中越来越受欢迎,可用于预防 CNV。手术治疗包括血管闭塞和眼表重建,具体取决于病因和对药物治疗的反应。未来的治疗方法应为 CNV 的管理提供更有效的治疗选择。
