老年黄斑变性（ａｇｅ－ｒｅｌａｔｅｄｍａｃｕｌａｒｄｅｇｅｎｅｒａｔｉｏｎ，ＡＭＤ）由于发病原因及机制不清，药物、激光及手术等治疗虽取得一定效果，但最终患者的中心视力仍受到严重损害。近来，国外学者应用放射治疗，使大部分患者视网膜下新生血管膜（ｓｕｂｒｅｔｉｎａｌｎｅｏｖａｓｃｕｌａｒｍｅｍｂｒａｎｅｓ，ＳＲＮＶＭ）萎缩，视力得以保持和改善，结果令人鼓舞，开辟了一条有希望的治疗新途径 Age-related macular degeneration (AMD) may have some effect on the treatment of drugs, lasers and surgery because of the etiology and mechanism of the disease.

The result is encouraging and opens up a promising new therapeutic approach
