Figure 3.

The ratio of an affected and unaffected area of each multifocal electroretinogram components. A) Ratio of N1–P1 and N2 amplitude before and 1 month after TES. N1–P1 and N2 amplitudes are increased after TES, N2 amplitude was significant (P < 0.05, paired t-test). B) Ratio of implicit times of N1, P1, and N2 before and 1 month after TES. N1 and P1 implicit times were decreased in comparison to the level of pre-TES. N1 and P1 had a significant decrease in the implicit times (P < 0.01 and P < 0.05, respectively).

Notes: **Increase or † and †† decrease was different from pre-TES group at P < 0.01 and P < 0.01 compared with pre-TES, paired t-tests.

Abbreviation: TES, transcorneal electrical stimulation.
