Abstract

Whole epon-embedded dystrophic extraocular muscles were serially sectioned at 20 microns. These sections were cleared for light microscopy and surveyed for abnormal fibers. Various morphologic disruptions associated with gross changes in diameter over hundreds of microns were observed. Electron microscopic samples reveal a continuum of different kinds of structural changes related to such variations in fiber diameter. These data indicate that a large assortment of ultrastructural changes can occur simultaneously in the same cell.
