Figure 4. Retinal insulin receptor, insulin growth factor–1 receptor, and insulin-like growth factor-1 mRNA levels after 4 and 24 h of plus (+7D) and minus (−7D) lens treatment. Results are expressed as the mean normalized expression (MNE)±SEM. For the 4 h experiment, six animals per groups were used; nine per group were used for the 24 h experiment. Insulin receptor (IR), insulin-like growth factor (IGF)-1 receptor (IGF-1R), and IGF-1 mRNA levels were not significantly influenced by lens wear in the retina.
