In the HVIP1 vitreous (Figure 4A), there were a number of significant correlations identified: CRP/Myoglobin, IGFBP-4/SAA, IGFBP-4/VCAM-1, and VCAM-1/SAA in the endophthalmitis group; MPO/NGAL, CRP/SAA, and Cystatin C/Myoglobin in controls; and NGAL/MMP-9 in both groups. The gene discussed is MMP9; the disease is endophthalmitis.
