CCL4 and cataract: The MCP-3 (P = 0.012), MDC (P < 0.001), and VEGF (P = 0.033) concentrations were significantly higher in the PACG group than in the cataract group, while the MCP-1 (P = 0.021) and MIP-1β (P = 0.022) concentrations were significantly decreased in the aqueous humor of the PACG patients.
