Causes of Macular degeneration原因性黄斑变性

Macular degeneration results in a partial breakdown of the retinal pigment epithelium (RPE).性黄斑变性的结果，在部分细分的视网膜色素上皮细胞（视网膜色素上皮） 。 The RPE is the insulating layer between the retina and the choroid (the layer of blood vessels behind the retina).色素上皮是绝缘层之间的视网膜和脉络膜（层血管背后的视网膜） 。 Fluid leakage occurs, and new blood vessels growing from the choroid destroy the retinal nerve tissue and replace it with scar tissue and the light-sensitive cells in the macular are damaged.脑脊液漏的发生，和新血管的成长，从脉络膜破坏视网膜神经组织和取代它的瘢痕组织和对光敏感细胞在黄斑损坏。 The cause is unknown.原因是未知之数。
