玻璃体的作用有二:一为眼屈光间质之一,主要通过光线。二为支撑眼球,支持视网膜于特定之位置,维持眼球形态。玻璃体是典型的凝胶,有细纤维结构及同样屈光指数的液体。玻璃体饱和水分98～99%,处于最大肿胀状态。在水分内含有糖、尿素、钙、钾,较大量的食盐及其他盐类。蛋白质含量较少,由0.9～1.36%,其中白蛋白占优势。其成分中除了
The role of the vitreous has two: one for the eye one of the refractive interstitial, mainly through the light. Second, to support the eye, support the retina in a specific location to maintain the eye shape. The vitreous is a typical gel with fine fiber structure and the same refractive index of the liquid. Vitreous water saturation of 98 to 99%, at the maximum swelling state. In the water contains sugar, urea, calcium, potassium, a larger amount of salt and other salts. Protein content less, from 0.9 to 1.36%, of which albumin dominant. In addition to its ingredients
