title: [An ultrastructural study on human retina with late glaucoma].
abstract: OBJECTIVE
  To study the pathologic changes of retina in glaucoma.
  
  
  METHODS
  Retinas from 6 cases with absolute glaucoma were observed by transmission electron microscope.
  
  
  RESULTS
  It was found that the nerve fiber layer was significantly thin and the axons were severely damaged even lost; the ganglion cells nearly disappeared and a number of cell-like bodies were seen instead; the nerve cells of the outer and inner nuclear layers were degenerated, decreased in number, and disorderly arranged; the outer segments of the cone and rod cells became degenerative and edematous.
  
  
  CONCLUSIONS
  In advanced glaucoma the degeneration and atrophy of the ganglion cells and their nerve axons were the major pathologic changes of the retina that lead to the permanent damage of visual function.
