Table 2. Comparison of the frequency of MLBs
Greater than 1 mm2 of fetal and embryonic nuclear regions were searched in each of 5 normal and 5 cataractous nuclei. A total of 83 MLBs in the cataracts, but only 8 in the normal lenses, were observed in about 8 mm2 of histological sections examined from each type of specimen. Comparing the MLBs per unit area examined, the cataracts exhibited 10.4 MLBs/mm2, whereas the normal lenses showed only 1.4 MLBs/mm2. The Mann-Whitney statistical test for small n supports the trend that the cataracts have more MLBs than the normals (p=0.016).
