The neural mechanisms for optokinetic nystagmus (OKN) may be clinically relevant to the two methods used to detect these abnormalities. If one subscribes to the cortical (macular) theory, visual fixation is always involved and results by conventional drum rotation or by pursuit of a moving light source ought to be the same. Conversely, if OKN can be the result of peripheral vision and subcortical pathways, results with the drum (which does not require macular vision) and moving light (which does) ought to be different. Both the drum and moving light methods were compared on a sample of 514 patients. Both methods compared equally in eliciting abnormal responses in patients with an established diagnosis and in correlation with calibration, gaze, and false positive responses. The drum was superior in the remainder of comparisons.
视动性眼球震颤（OKN）的神经机制在临床上可能与用于检测这些异常的两种方法相关。如果认同皮质（黄斑）理论，视觉注视总是会涉及其中，那么通过传统鼓轮旋转或追踪移动光源所得到的结果应该是相同的。相反，如果OKN可能是周边视觉和皮质下通路的结果，那么使用鼓轮（不需要黄斑视觉）和移动光源（需要黄斑视觉）所得到的结果应该是不同的。对514名患者的样本进行了鼓轮和移动光源两种方法的比较。在已确诊患者中引发异常反应以及在校准、注视和假阳性反应方面的相关性上，两种方法的比较结果相当。在其余的比较中，鼓轮方法更具优势。
