Results The P100 amplitude showed a significant difference among all treatment sessions with a decreasing trend in the study group after PRP ( P <0.001).

In the P100 latency analysis, one of the most diagnostic visual evoked potential parameters, P100 wave latency changes showed an increasing trend after laser therapy in the study groups so that after first, second and third laser therapy sessions, an approximate increase of 2.7%, 2.6% and 3.3% of the corresponding wave in latency was occurred, respectively.
