眼后节穿通伤后玻璃体增殖引起牵拉性视网脱离,发生严重的视力障碍。手术清除玻璃体及其出血,是防止玻璃体增殖的方法。但玻璃体切除术本身可有严重的合并症。为此,作者提供一较为简单并更容易的办法。如果能中断增殖过程的生物化学反应,则将能阻止增殖。青霉胺是铜、汞、锌、铅的螯合剂,用于治疗金属中毒及患Wilson病,也用于治疗类风湿性关节炎。用其防止胶原索条形成的基本原理在于它能阻止胶原纤维交叉连结。成纤维细胞内形成的前胶原(Procollagen)从细胞内逸出,并自动排成微原纤维(microfibrils)。该微 Posterior eye through the injury caused by vitreous proliferation of traction retinal detachment, a serious visual impairment. Surgical removal of the vitreous and its bleeding is to prevent the proliferation of vitreous. However, vitrectomy itself may have serious complications. To this end, the author provides a simpler and easier way. If you interrupt the biochemical reactions in the proliferative process, you will be able to stop the proliferation. Penicillamine is a chelating agent for copper, mercury, zinc and lead for the treatment of metal poisoning and Wilson’s disease and for the treatment of rheumatoid arthritis. The rationale for using it to prevent the formation of collagen strands is that it prevents the cross-linking of collagen fibers. Procollagen formed within fibroblasts escapes within the cell and automatically lides into microfibrils. The micro
