对20例玻璃体手术中摘除的症状性黄斑上膜进行了光镜、扫描和透射电子显微镜检查。这些膜含有胶质细胞和色素上皮细胞，但也发现肌成纤维细胞和成纤维细胞，它们的起源在形态上无法确定。膜可以分为两种类型。其中一组膜由大量交替的胶原层和细胞层以及一些内部限制层组成。第二种膜通常由单层细胞组成，视网膜表面有大片内界膜，几乎没有胶原蛋白。这两种类型的膜在被移除的内部限制层的视网膜一侧都有细胞，推测这些细胞来自神经感觉性视网膜。
Twenty symptom-producing epimacular membranes removed during vitreous surgery were examined by light microscopy, scanning and transmission electron microscopy. These membranes contain cells of glial and pigment epithelial origin, but one also finds myofibroblasts and fibroblasts which cannot be identified morphologically as to their origin. The membranes can be classified into two types. Membranes in one group are composed of numerous alternating layers of collagen and cells and some internal limiting lamina. The second type of membrane is generally composed of a single layer of cells with large sheets of internal limiting lamina from the retinal surface and little if any collagen. Both types of membranes have cells on the retinal side of the removed internal limiting lamina, presumably derived from neurosensory retina.
