Abstract：视网膜下腔存在有限度的免疫赦免,针对接种抗原可诱导抗原特异性体液和细胞免疫反应的抑制.同种异体视网膜色素上皮细胞(retinal pigment epithelium, RPE)具有一定的免疫原性.在未实施免疫抑制剂的情况下,大部分接受视网膜下腔RPE移植治疗老年相关性黄斑变性(age-related macular degeneration, AMD)的患者发生了移植排斥反应.这些移植细胞是否能改善渗出型AMD的视力预后还需进一步的研究.其手术并发症有:囊样黄斑水肿、黄斑皱褶和孔源性视网膜脱离.与此相反,在接受神经视网膜组织移植的晚期视网膜变性患者在术后长期观察期间未发现显著的排斥反应征象及其严重的并发症.但是,移植的神经组织能否重建视网膜内神经网络及其治疗效果还有待进一步研究.综述文献
