Ultrastructure of the lens epithelium in Alport's syndrome.
The ultrastructure of the lens epithelium in Alport's syndrome was studied. In a transmission electron-microscopic examination, a large number of tonofilaments, swollen mitochondria, a dilated Golgi complex, a dilated rough endoplasmic reticulum with electron-dense (osmiophilic) material in some of these irregular structures and myelin figures were observed. Most of the cells had regularly shaped and only a few of them irregularly shaped nuclei. Additionally, polymorphism and marked degeneration in the transitional zone were observed in the scanning electron-microscopic examination of the lens epithelium. After the transitional zone, there were no epithelial cells present under the lens capsule, an observation that has never been reported in the literature.
