Fig. 4.

Effect of treatment of a mouse model of type 2 diabetes (HF + STZ) with menhaden oil or resolvin D1 on subepithelial cornea nerve fiber length. Subepithelial cornea nerve fiber length was determined as described in materials and methods. Representative images are shown for each condition. Data are presented as the means ± SE in mm/mm². The number of mice in each group was the same as shown in Table 2. Scale bar = 50 μm. ***P < 0.001, compared with control mice; +P < 0.05, compared with nontreated diabetic mice.
