[Specular microscopy of the corneal endothelial cells in diabetes].

The corneal endothelia of 60 eyes of diabetic patients were studied by contact specular microscopy to find that the mean cell density differed insignificantly from that of the normal controls; however, the percentage of non-hexagonal cells was significantly higher in the diabetics than in normal controls. The disturbance in cellular structure might be the pathological basis of endothelial dysfunction in diabetes.
