Quite a number of pathological factors exist that can disturb the balance between anti-angiogenic and proangiogenic mechanisms, thus causing vascularization of the cornea. The neovessels are immature, ill-formed, and show increased permeability, which is dangerous of corneal edema, lipid deposition, and opacification. Moreover, as known, corneal neovascularization (CNV; preexisting or postoperative) may contribute to immune response against the transplant. Suppression of neovascularization is able to decrease the risk of corneal transplant rejection. In order to identify the principal strategy for struggling against CNV, we should first get a better understanding of its etiology, pathogenesis, and role in transplant immunity as well as mechanisms of action of available treatment methods.
存在许多病理因素会干扰抗血管生成和促血管生成机制之间的平衡,从而导致角膜血管化。新生血管不成熟、形态不良且通透性增加,这会导致角膜水肿、脂质沉积和浑浊,十分危险。此外,众所周知,角膜新生血管(术前或术后存在)可能会引发针对移植体的免疫反应。抑制新生血管生成能够降低角膜移植排斥反应的风险。为了确定对抗角膜新生血管的主要策略,我们首先应该更好地了解其病因、发病机制、在移植免疫中的作用以及现有治疗方法的作用机制。
