虽然延迟的视觉诱发电位被认为是视神经疾病的标志，但关于黄斑疾病的VEP延迟的报道相对较少。在这项研究中，对20例获得性单眼黄斑病变或双眼黄斑病变的患者进行了评估，其中一只眼比另一只眼受影响更严重。比较可记录时两眼的VEP波幅和峰潜伏期。9名患者(45%)的患眼或更严重的眼表现出明显的眼间延迟，而只有4名患者(20%)的眼间波幅有明显的减弱。在表现出延迟的9名患者中，3名患者的患眼或更多患眼的视力达到了20/30或更高。在表现出幅度衰减的患者中，没有患者的受累或更严重受累的眼睛的视力超过20/50。虽然黄斑病变中VEP延迟的机制尚不清楚，但VEP延迟不应单独用于黄斑和视神经疾病的鉴别诊断。在推测存在视觉通路功能障碍之前，临床医生应明确排除任何VEP延迟的患者中存在黄斑病变。
Although a delayed visual evoked potential is considered to be the hallmark of optic nerve disease, relatively little has been published about VEP delays in macular disease. In this study, 20 patients with either acquired unilateral maculopathy or bilateral maculopathy in which one eye was more affected than the other were evaluated. VEP amplitudes and peak latencies were compared between eyes when recordable. Nine patients (45%) exhibited significant interocular delays in the affected or more affected eye while only four patients (20%) exhibited significant interocular attenuations in amplitude. In the nine patients exhibiting delays, three patients had a visual acuity of 20/30 or better in the affected eye or more affected eye. In the patients exhibiting amplitude attenuations, no patient had a visual acuity better than 20/50 in the affected or more affected eye. Although the mechanism of VEP delays in maculopathy is not clear, a VEP delay, in isolation of other tests, should not be used in the differential diagnosis of macular vs optic nerve disease. The clinician should specifically rule out macular disease in any patient with a delayed VEP before presuming the presence of a visual pathway dysfunction.
