Figure 4

Retinal histology on the 4^th, 7^th, 14^th day after a single injection of 50 μL PBS or 0.2, 0.5, 2.0 mg of conbercept and on the 7^th day after the 6^th multiple injections of 50 μL PBS or 0.2 mg of conbercept. There was significant difference in the cell number in the ganglion ccell layer (GCL) and the thickness of inner nuclear layer (INL) (p > 0.05). The results were mean ± SEM (n = 3). Scale bar: 50 μm.
