Electroretinograms (ERGs) and visually evoked potentials (VEPs) were recorded simultaneously from each eye of three adult amblyopes. A spatially alternating checkerboard pattern stimulus of constant mean luminance was used to eliminate the effect of stray light on the ERG. The VEP was affected in the amblyopic eye of all subjects. In two subjects the VEP amplitude was reduced; in the third subject the amplitude was not attenuated, but the waveform of the VEP was markedly altered. Photopic ERGs recorded from the normal and amblyopic eye of each subject with an unpatterned flashing light were equal in amplitude. However, ERGs elicited by a patterned stimulus were affected in the amblyopic eye of all three subjects; the after-potential showed larger reductions in amplitude than the b-wave. These results suggest there may be some retinal involvement in human amblyopia.
同时记录了三名成年弱视患者每只眼睛的视网膜电图（ERG）和视觉诱发电位（VEP）。使用具有恒定平均亮度的空间交替棋盘格图案刺激来消除杂散光对ERG的影响。所有受试者的弱视眼的VEP均受到影响。两名受试者的VEP振幅降低；第三名受试者的振幅未减弱，但VEP的波形明显改变。用无图案闪光从每个受试者的正常眼和弱视眼记录的明视ERG振幅相等。然而，由图案刺激诱发的ERG在所有三名受试者的弱视眼中均受到影响；后电位的振幅比b波的振幅降低得更大。这些结果表明人类弱视可能存在一些视网膜受累情况。
