摘要
报告采用直流电锌离子导入治疗伴有血清锌水平降低或血清铜/锌比值异常的26例视网膜色素变性病人的初步疗效。病人经20～30次的治疗后,视力提高三行以上的眼数有15.38%;视野改善超过5°的眼数为4%,暗适应阈值下降幅度大于1.0的眼数为13.46%,其余为视功能无改变或变化不大者。治疗前后病人的眼底形态没有明显变化;4例8眼的治疗前后 ERG 检查结果基本一致。文章还就锌离子导入法和口服锌化合物制剂法的优缺点比较,直流电对视力的可能增强作用,锌元素与维生素 A 代谢的关系及影响暗适应的机制,作了简要的讨论。
We report here the prelimilary effects of zinc iontophoresis in treatment of 26 Rp patients who had decreased zinc serum level or abnormal ratio of serum copper to zinc.Through more than 20 to 30 times of therapy,the vision of 15.38% eyes increased more than “3 lines”,4% eyes increased more than 5°in the visual field,13.46% eyes improved in dark adaptation threshod (>1.0), the visual functions of the rest eyes were slightly improved or unimproved.The fundus didn't change before & after treatment.There were no changes of ERG in 8 eyes of 4 cases.In addition,the advantages and disadvantages between Zn iontophoresis and Zn compound taken orally,the improvement of vision by direct electric current therapy,the relationship between the metabolism of Zn element and Vit A and influence of Zn over the mechnism of dark adaptation were also briefly discussed.
