Abstract
Visually evoked potentials to checkerboard pattern reversal were found to be nearly five times larger in eccentrically fixing amblyopic eyes than in centrally fixing amblyopic eyes when compared with the fellow non-amblyopic eye. The two groups of amblyopes had comparably poor visual acuity and differed in no other way save in their fixation behaviour. This suggests that at least two neurodevelopmental mechanisms subserve human amblyopia and that only one of these resembles the animal model of visual deprivation.
摘要
与对侧健眼相比，发现偏心注视的弱视眼对棋盘格图案翻转的视觉诱发电位比中心注视的弱视眼大四倍。两组弱视患者视力同样差，除了注视行为外没有其他差异。这表明至少有两种神经发育机制导致人类弱视，且其中只有一种类似于视觉剥夺的动物模型。
