許多疾病的发生与自家免疫有一定关系。目前对自家免疫的机制虽尚未完全明了,但一般认为机体自身的某些器官的組織成分进入血液循环后可成为自家抗原,并引起相应的抗体产生,这种抗体有时对同种及异种动物之相同器官也可发生血清学反应。另外,机体自身的組織成分在一定条件或外界某些因素影响下,改变了原来的蛋白性质,也可刺激机体产生抗体,且引起抗原和抗体反应。在眼科領域中,某些疾病的发生也与自家免疫有关。最常見的可以举出两种: 1.晶状体过敏性虹膜睫状体炎这是在白內障囊外摘出术、线状摘出术或截囊术后,由于晶状体皮质到达前房內,对某些病人所引起的过敏性虹膜睫状体炎。在正常状况下,晶状体在胚胎时期的发育成长与抗体的发育系就是相隔离的。因此在出生后,如果晶状体組織一旦由于某种原因进入血液后,就会成为异源性物质也就是抗原,由于这种抗原的刺激可以产生抗体,因而发生对其自身組織的免疫或敏感作用。这种現象常見于白內障囊外摘出术后留下較多 Many diseases have a certain relationship with their own immune system. At present, although the mechanism of its own immunity is not yet fully understood, it is generally believed that the tissue components of some organs of the body itself can become self-antigens after being circulated in the bloodstream and cause the corresponding antibody production. Such antibodies are sometimes used against homologous and heterologous animals Serological reactions can occur in the same organ. In addition, the body’s own organizational components under certain conditions or under the influence of certain external factors, changing the nature of the original protein can also stimulate the body to produce antibodies, and cause antigen and antibody reactions. In the field of ophthalmology, some diseases are also related to their own immune system. The most common can be cited in two ways: 1. Lens allergic iridocyclitis This is in the extracapsular cataract extraction surgery, linear extirpation surgery or cyst surgery, the lens cortex reached the anterior chamber, for some patients Caused by allergic iridocyclitis. Under normal conditions, the growth and development of the lens during embryonic development and antibody development is isolated. Therefore, after birth, if the lens tissue once into the blood for some reason, it will become a heterologous substance or antigen, because the antigen can stimulate the production of antibodies, which occurred on its own organization immune or sensitive role. This phenomenon is common in extracapsular cataract surgery left more
