Qualitative and Quantitative Analysis of B-Cell-Produced Antibodies in Vitreous Humor of Type 2 Diabetic Patients with Diabetic Retinopathy

Figure 2

The concentrations of IgA, IgM, and antibodies in the vitreous humor of the two groups. Abbreviations: DR: diabetic retinopathy; Ig: immunoglobulin. (a) The concentration of IgA antibody (ng/ml) in the vitreous humor of the DR patients and the control group. (b) The concentration of IgM antibody (ng/ml) in the vitreous humor of the DR and control groups. (c) The concentration of antibodies (ng/ml) in the vitreous humor of the DR group and the control group. The levels of IgA, IgM, and total antibodies in the vitreous humor were significantly higher in the DR group than in the control group. Statistically significant value < 0.001 by independent, two-tailed Student’s -tests.
