Photopic negative response (PhNR) of normal and laser-treated mouse eyes.

<p>A: a wave, b wave and PhNR of untreated left control eye (OS) and laser-treated right eye (OD) of step 1 with the stimulus at 1 cd.s/m². B: Depicts the waves of step 2 with the stimulus at 5 cd.s/m². C: Represents the waves of step 3 with the stimulus at 7 cd.s/m². D: Shows the statistical analysis of the amplitude of PhNR at step 2 with the stimulus at 5 cd.s/m² compared to the laser-treated and untreated control eyes (<i>p</i><0.0001, paired <i>t</i>-test).
