黄斑区随着年龄增长而发生的变化称为年龄相关性黄斑变性(Age-relatedMacular Degeneration,AMD),或称老年性黄斑变性(Senile Macular Degenera-tion,SMD)。这是目前65岁以上老年人视力丧失的首要原因。在美国老年人失明或低视力的眼病依次为老年性白内障、老年性黄斑变性、开角型青光眼,糖尿病性视网膜病变。自从开展显微眼科手术以来,白内障较早手术,术后不论是人工晶体植入或配戴合适的眼镜,均能恢复一定的视力,故白内障致盲的重要性已明显减低,而年龄相关性黄斑变性的严重性却相对地变得更为突出,成
The change of macular area with age is called Age-relatedMacular Degeneration (AMD), or Senile Macular Degeneration (SMD). This is the primary cause of vision loss in the elderly over the age of 65. In the United States, blindness or low vision of the elderly eye diseases were age-related cataract, age-related macular degeneration, open-angle glaucoma and diabetic retinopathy. Since microscopic ophthalmic surgery has been carried out, cataract surgery earlier, regardless of whether intraocular lens implantation or wearing appropriate glasses, can restore some vision, so the importance of blindness has been significantly reduced, and age-related The severity of macular degeneration is relatively more prominent, into
