我们使用扫描激光检眼镜（SLO）记录视觉诱发反应（VERs）交替，棋盘图案的刺激。在整个测试过程中，在SLO视频监视器上监测视网膜位置和棋盘刺激的焦点。棋盘大小、检查大小和视网膜位置是不同的。与其他成熟的图案反转技术一致，SLO方法产生：1）可靠的VERs，振幅为2至10微伏，2）对于固定的总体图案尺寸，中间检查尺寸处的最大振幅，以及3）根据刺激视网膜的变化而变化相对于中央凹的位置。因此，当需要精确的视网膜刺激位置和焦点时，SLO-VER技术将用于临床VER测量。
We recorded visual evoked responses (VERs) to alternating, checkerboard pattern stimuli using the scanning laser ophthalmoscope (SLO). Retinal position and focus of checkerboard stimuli were monitored on the SLO video monitor throughout testing. Checkerboard size, check size, and retinal positions were varied. Consistent with other, well‐established pattern reversal techniques, the SLO method produced: 1) reliable VERs with amplitudes of 2 to 10 microvolts, 2) maximum amplitudes at an intermediate check size for a fixed overall pattern size, and 3) variations in VER amplitude depending on stimulus retinal position relative to the fovea. Hence, the SLO‐VER technique would be useful for clinical VER measurements when precise retinal stimulus position and focus are desired.
