黄斑区是视网膜的一个重要区域,也是视网膜最薄的区域。视网膜一般有十层组织,而黄斑区会少几层。黄斑中央的凹陷称为中央凹,是视觉最敏锐的地方。我们平时查视力,就是检查黄斑的功能。一人人都有黄斑经常有人会问:“黄斑是不是指我眼睛里长斑了?”其实,黄斑每个人都有,只是有些人的黄斑可能出现了病变。黄斑病变的特点是视力下降和视物变形。低级动物是没有黄斑的,如苍蝇的眼是复眼,它就没有黄斑;犬的眼是色盲眼,它也没有黄斑。
The macula is an important area of the retina and is the thinnest area of the retina. Retina generally have ten layers of tissue, while the macular area will be less layers. The central fovea of the macula is called the fovea and is the most visually sensitive place. We usually check visual acuity, that is, check the function of the macula. Everyone has a macula Someone often will ask: “Does the macula do not mean my macula has long spots?” In fact, the macula is for everyone, except for some who may have macular degeneration. Macular degeneration is characterized by decreased visual acuity and visual distortion. Low-level animals are macula-free, such as fly eyes are compound eyes, it has no macular; dog’s eyes are color-blind, it does not have macular.
