Figure 3: Diabetic rat retinal thickness is decreasing at 30 d after diabetic rat model established (before the treatment). (a) Representative OCT cross-sectional image of retina. (b) The thickness of ILM + NFL; (c) the thickness of GCL + IPL; (d) the thickness of INL; (e) the thickness of OPL; (f) the thickness of ONL; (g) the thickness of EML to RPE; (h) the thickness of entire retina. ILM+NFL: internal limiting membrane and nerve fiber layer; GCL + IPL: ganglion cell layer and inner plexiform layer; INL: inner nuclear layer; OPL: outer plexiform layer; ONL: outer nuclear layer; EML to RPE: external limiting membrane to retinal pigment epithelium. Values are presented as mean ± SD, n=10, p < 0.05, p < 0.01: untreated diabetic model group, CaD group, FSM high-dose, FSM medium-dose, and FSM low-dose group vs normal group; #p < 0.05: CaD group, FSM high-dose, FSM medium-dose, and FSM low-dose group vs untreated diabetic model group.
