A). The levels of CTGF (determined by ELISA) were significantly elevated in the AH of POAG patients compared to cataract subjects (n=27) based on the Mann Whitney U test. The data represent the median, 5% and 95% quartile range and each dot represents individual patients/subjects. B). While the correlation between AH CTGF levels and preoperative IOP in POAG patients was not statistically significant (Pearson Correlation Coefficient = 0.233, 95% CI = −0.162 to 0.563, p = 0.243), C). There was a significant correlation between the levels of CTGF and ATX in AH from POAG patients (Pearson Correlation Coefficient = 0.568, 95% CI = 0.240 to 0.780, p≤0.001).
