Figure 4. CNV scores at 14 and 21 days after laser photocoagulation in ovariectomized female rats with or without E2 treatment

After a 7 day washout period, ovariectomized rats received photocoagulation. E2 (10 μg/day) was administrated intraperitoneally for 14 and 21 days in the E2 treated group. The bars represent mean results (8 to 10 eyes); the error bars represent the standard error of the mean. Asterisk and double asterisk mark significant (p<0.05 and p<0.01, respectively) differences.
