Effect of UVA light in vivo on the percent increase in gray scale level from the guinea pig lens cortex to the nucleus*

Percent increase in gray level
Control (10) 14 ± 4

*

Guinea pigs were exposed to UVA light for five months and the eyes photographed using slit lamp biomicroscopy (Fig. 6). The percent increase in gray scale level from the lens cortex to the nucleus was determined as described in Materials and Methods for experimental and age-matched control animals (23 months old). Results are expressed as means ±s.d. The number of experiments is in parentheses.
