In three patients with psychogenic amblyopia the computerized visual field, the ERG, the flash light (H-EP) and pattern reversal stimulated (M-EP) cortical potentials were recorded. Differential diagnosis between psychogenic amblyopia on the one hand, and functional amblyopia and organic lesions of the retrobulbar visual pathways on the other was shown to be possible. In the cases with organic retrobulbar lesions of visual pathways, visual field defects and pathologic H-EP's and M-EP's were found. In functional amblyopia only the M-EP responses are diminished in amplitude. In psychogenic amblyopia only the computerized visual field shows pathologic changes.
对三名患有精神性弱视的患者进行了计算机化视野、视网膜电图、闪光刺激（H-EP）和图形反转刺激（M-EP）皮层电位的记录。结果表明，一方面可以鉴别精神性弱视，另一方面也可以鉴别功能性弱视和球后视神经通路的器质性病变。在球后视神经通路存在器质性病变的病例中，发现了视野缺损以及病理性的H-EP和M-EP。在功能性弱视中，只有M-EP反应的振幅降低。在精神性弱视中，只有计算机化视野显示出病理性变化。
