我们制作了偏振光影像不等检查仪,并用此仪器检查了50例正常限,100例屈光不等用普通眼镜矫正后的影像不等和7例单眼无晶体用普通眼镜矫正后的影像不等。对50例影像不等作了立体视敏度的测定。对后两组病人我们同时用NAT测定,其数值是相同的。 通过测定证明,正常人存在生理性影像不等,其最大值是1.5％,屈光参差度和影像不等不完全成正比关系。轴性屈光参差大于3.0D时仍可用普通眼镜矫正。与过去的常规看法有所不同。当影像不等大于4％时,立体视消失。单眼无晶体用眼镜矫正后的影像不等是11～24％。
We produced a polarized light image ranging from the instrument, and with this instrument check the 50 normal limits, ranging from 100 cases of refractive anisomethonsion ranged from ordinary glasses and 7 cases of monocular non-crystal with ordinary glasses after correction of the image is not Wait. 50 cases of images ranging from stereoscopic sensitivity determination. For the last two groups of patients, we also use NAT measurement, the value is the same. Proved by measurement, there are physiological images of normal range, the maximum is 1.5%, anisometropia and the image is not exactly proportional to the relationship between. Axis anisometropia greater than 3.0D can still be corrected with ordinary glasses. Different from the conventional wisdom. Stereoscopic disappears when the image is not larger than 4%. Monocular aphakia with glasses after correction of the image ranged from 11 to 24%.
