研究了弱视者是否对阈值刺激以外的其他刺激表现出对比度缺陷。弱视测量的阈值缺陷与阈值以上发生的情况没有简单的关系。在日常视觉典型的高对比度范围内，弱视不存在对比度编码异常。提出了屈光参差性和斜视性弱视的不同神经基础的阈上证据。
Whether amblyopes exhibit contrast deficiencies for other than threshold stimuli was investigated. The threshold deficits measured in amblyopia showed no simple relationship to what happens above threshold. No contrast coding abnormality existed in amblyopia in the high-contrast range typical of everyday vision. Suprathreshold evidence for different neural bases in anisometropic and strabismic amblyopia is presented.
