A keratoconus removed from an 18-year-old male was processed for SEM and examined with special attention for the epithelial surface. A broad degenerative band was found running in the vertical meridian, showing areas devoid of, or with only partially attached, epithelial cells, and also areas with abnormal cells either, with a defective cell membrane and without cell contents or with an intact cell membrane but without a cell nucleus. Stereoscopic images of these defective cells show that cell degeneration is sometimes found several cell layers deep into the epithelium.
从一名18岁男性身上取出的圆锥角膜组织进行了扫描电子显微镜（SEM）处理，并特别关注上皮表面进行检查。发现一条宽阔的变性带沿垂直子午线走行，可见上皮细胞缺失区域或仅部分附着的区域，以及存在异常细胞的区域，这些异常细胞要么细胞膜有缺陷且无细胞内容物，要么细胞膜完整但无细胞核。这些缺陷细胞的立体图像显示，有时在上皮细胞深层数层处会发现细胞变性。
