Figure 1. Distribution of TIMP1 (A), TIMP2 (B), TIMP4 (C), and MMP2 (D) concentrations in aqueous humor samples from non-glaucomatous cataract (blue; N=15-26) versus POAG (orange; N=16-22) patients. Levels of all four analytes shown were significantly increased in POAG aqueous humor samples, as determined using the Mann–Whitney U test (p<0.05). Medians and interquartile ranges are indicated. See Table 2 for a complete list of analyte concentrations measured.
