Figure 2. OCT scans of mice treated with NaIO₃ or NaIO₃ + TMP at three time points. Top, middle, and bottom: The three groups at day 3, 7, and 14 after NaIO₃ administration. Left to right: The control group, the NaIO₃-degenerated group (Group I), and the tetramethylpyrazine (TMP) group. Yellow double-headed arrows mark the outer nuclear layer (ONL) thickness. Red arrows mark the RPE migrated into the inner and outer segments (IS/OS).
