We tried to quantitate the opacification of the human lens nucleus. We recorded the Scheimflug image fo the lens and measured the scattering light intensity at the anterior and posterior borders of the fetal nucleus. The difference between the two values ranged from +3 to -25 CCT usits in 267 noncataractous subjects. The value rangedbetween +5% and -5%, in 80% of these cases. The values were independent of aging. The scatter-ing light was more intense in the anterior than in the posterior face of fetal nucleus in 18 eyes with nuclear cataract. The values ranged from 0 to 33 CCT units. The values were positively correlated with the subjective grading of nuclear opacifica-tion.
