Figure 4From: Analysis of nuclear fiber cell compaction in transparent and cataractous diabetic human lenses by scanning electron microscopy Average count of embryonic nuclear fiber folds per 20 microns. Folds of membrane (arrows) on the surface of embryonic nuclear fibers were counted from peak to peak over a 20 μm distance. Transparent diabetic lenses (A) averaged 6.53 folds per 20 μm, while the cataractous diabetics (B) had a mean of 6.95 folds, an increase of 6%.Back to article page
