Figure 2. Changes in guinea pig body weight and corneal thickness over 15 weeks. A: Average (±standard deviation) body weight of guinea pigs fed a normal (AA+) or ascorbic acid deficient deficient (AA-) diet, with (UVB+) or without (-) daily UVB exposure. From week 9 onwards body weight was significantly lower in the ascorbic acid deficient animals (p<0.01).  B: Average (±standard deviation) corneal thickness measurements from the same guinea pigs revealed a significant increase in corneal thickness following UVB-exposure (p<0.01). Moving average trend lines show the pattern of animal growth and corneal thickness change during the course of the study.
