根据角膜周边部和角膜缘免疫学特点:①免疫球蛋白、补体、各种细胞免疫成份有分布:IgM、C3、LC、LCS、HLA 周边部均高于角膜中央部。②与免疫有关疾病如:蚕食性角膜溃疡、泡性结角膜炎,边缘性角膜浸润等发生在周边部;而感染性疾病如:细菌、霉菌、病毒性角膜炎等发生在中央部。③抗体主要在基质中,以IgG、IgA 含量为高。放射状角膜切开术切开的是角膜周边部而保留中央光学区,这手术对局部免疫是否有影响,是对手术安全性和稳定性探讨。泪液内免疫球蛋白除受角膜影响外,还受其它因素影
According to immunological characteristics of corneal peripheral and limbal margins: ① immunoglobulins, complement, a variety of cellular immune components are distributed: IgM, C3, LC, LCS, HLA peripheral department were higher than the central cornea. ② immune-related diseases such as: nocturnal corneal ulcer, conjunctival keratitis, marginal corneal infiltration occurred in the periphery; and infectious diseases such as: bacteria, fungi, viral keratitis occurred in the central department. ③ antibodies mainly in the matrix to IgG, IgA content is high. Radial corneal incision is the corneal peripheral incision and keep the central optical zone, whether the surgery on the local immunity has an impact on the safety and stability of the surgery. In addition to the impact of corneal tear immunoglobulin, but also by other factors
