We found that refractive errors were present in about 80% of 650 mentally retarded infants and children. The appropriate spectacles were prescribed for 75%. Evaluation of the effectiveness of wearing spectacles was based on the observation of their daily behavior and visually evoked cortical potentials to pattern stimuli (PVECP). Despite difficulties, we are able to record PVECPs in 160 subjects, of whom PVECPs were detectable in 140 (87.5%). The amplitudes of PVECPs with spectacles were larger than those without spectacles in 55.2% of the 105 subjects whose PVECPs were examined both with and without spectacles.
我们发现，650名智力发育迟缓的婴幼儿中约80%存在屈光不正。为其中75%的患儿开具了合适的眼镜。通过观察他们的日常行为以及对图形刺激的视诱发电位（PVECP）来评估戴眼镜的效果。尽管存在困难，我们仍能够在160名受试者中记录PVECP，其中140名（87.5%）可检测到PVECP。在105名同时接受戴眼镜和不戴眼镜PVECP检查的受试者中，55.2%的人戴眼镜时PVECP的波幅大于不戴眼镜时。
