Table 4. Summary of the changes in Rod:Cone opsin ratios

The fold change in the rod to red/green (or blue) opsin ratio in trephined samples of retina taken from the macula, mid-periphery, or periphery was calculated. Comparisons were made between the left and right eyes of normal animals or experimental and control eyes of the glaucoma monkeys. The data shown are the mean (±SEM) of several animals examined in each region (the number of animals examined in each region is denoted in parentheses). RC=the ratio of rod to red/green (or blue) cone opsin in control retinas. RE=the ratio of rod to red/green (or blue) cone opsin in experimental retinas. Overall, monkeys with experimental glaucoma show a significant increase in the RE/RC for red/green cone opsins in the mid-peripheral retina relative to control monkeys (*p=0.046). Sample sizes for the macular region were too small to make a statistical comparison.
