Figure 5. Relationship between the severity of diabetic retinopathy (DR) and the aqueous interferon gamma-induced protein-10 (IP-10)
level. The results by measuring cytokines in the aqueous humor samples shows that the IP-10 level in aqueous humor increased
with increasing severity of DR, and this correlation was significant (r=0.674, p<0.001).
Table 3 shows the sampling sizes for each group according to the ETDRS retinopathy severity scale.
