Retinal photoreceptor orientational tendencies were assessed within both eyes of samples of control and selected functional amblyopic observers, with the psychophysical Stiles-Crawford (S-C) function used as an indicator. S-C function determinations were made at testing locations spanning 30 degrees of the horizontal meridian of the visual field and including the forced region. Normal-appearing S-C functions with peak locations which clustered within a subregion of the pupil were found for all but one of the eyes tested. The single exception was a non-amblyopic eye of one of the amblyopic observers. Thus, within this sample of amblyopic eyes, visual acuity deficits are apparently not related to retinal photoreceptor alignment anomalies.
在对照样本和选定的功能性弱视观察者的双眼内评估视网膜光感受器的定向趋势，使用心理物理学的斯泰尔斯-克劳福德（S-C）函数作为指标。在跨越视野水平子午线30度并包括强制区域的测试位置进行S-C函数测定。在所测试的眼睛中，除了一只眼睛外，其他眼睛均发现S-C函数正常，其峰值位置聚集在瞳孔的一个子区域内。唯一的例外是一名弱视观察者的一只非弱视眼。因此，在这个弱视眼样本中，视力缺陷显然与视网膜光感受器排列异常无关。
