Flash visually evoked cortical potentials have been recorded in three groups of age- and sex-matched subjects; one comprised of subjects with dissociated vertical deviation, one comprised of subjects with oculocutaneous albinism and one group of controls. The latency of the major positive (P2) component did not show statistically significant contralateral lateralization on monocular stimulation in either the dissociated vertical deviation group or the control group. Contralateral lateralization was found in the albino group at a statistically significant level (P less than 0.01). It is concluded that subjects with dissociated vertical deviation do not possess the typical albino optic pathway misrouting that has been reported.
在三组年龄和性别匹配的受试者中记录了闪光视觉诱发电位；一组由分离性垂直偏斜受试者组成，一组由眼皮肤白化病受试者组成，还有一组为对照组。在分离性垂直偏斜组或对照组中，单眼刺激时主要正波（P2）成分的潜伏期在对侧未显示出统计学上的显著偏侧化。在白化病组中发现了具有统计学意义的对侧偏侧化（P小于0.01）。得出的结论是，分离性垂直偏斜受试者不存在已报道的典型白化病视神经通路错向。
