应用脑电功率谱对弱视儿童及正常儿童（各５０例）大脑枕部视区功能活动进行测定，并对两者进行了比较，结果表明：弱现儿童的视区脑电总功率比正常儿童减低，并表明斜视性弱视，屈光参差性弱视儿童枕区活动受到抑制，提示各型弱视的发病机理和病变部位并不相同，且一眼弱视，其对侧眼并非为正常眼。 EEG power spectrum was used to measure visual function of the occipital region of the visually impaired children and normal children (50 cases each), and the two were compared. The results showed that the total visual area EEG power of the weak children was lower than that of the normal children , And showed strabismic amblyopia, refractive anisometropic amblyopia in children with occipital activities were suppressed, suggesting that the pathogenesis of various types of amblyopia and lesions are not the same, and amblyopia, the contralateral eye is not a normal eye.
