Relative afferent pupillary defects (RAPD) were detected in 32.3% of patients with amblyopia by a modification of the swinging flashlight test and the synoptophore. After consideration of various clinical investigations the significant factors identified in patients showing a RAPD were: anisometropia, early age of onset where strabismus was present, level of visual acuity following treatment, longer period of occlusion therapy. These points bear similarities to the results of pattern electroretinograms (PERG) in amblyopes, and the possibility of the causative defect being at ganglion cell level is discussed. The effect of occlusion treatment cannot be predicted from the presence or absence of a RAPD.
通过改良的摆动手电筒试验和同视机，在32.3%的弱视患者中检测到相对性传入性瞳孔障碍（RAPD）。在综合考虑各种临床检查后，在出现RAPD的患者中确定的重要因素为：屈光参差、存在斜视时的发病年龄早、治疗后的视力水平、较长时间的遮盖治疗。这些要点与弱视患者的图形视网膜电图（PERG）结果相似，并讨论了病因缺陷可能存在于神经节细胞水平的可能性。不能根据是否存在RAPD来预测遮盖治疗的效果。
