Nystagmus intensities at various gaze angles were studied both preoperatively and postoperatively, using accurate ocular motility recordings, in three cases of congenital nystagmus. In addition to shifting the nystagmus null, the surgery broadened the null region and resulted in an overall reduction in nystagmus intensity at all gaze angles. Surgical rotation also resulted in improved visual acuity in all cases. The postoperative acuity at 0 degrees was better than the preoperative acuity at both 0 degrees and the patient's preferred gaze angle (ie, the preoperative null angle). This was not only for the two patients who showed an improved preoperative acuity with their head turn but also for the patient whose preoperative acuity did not substantially improve with her preferred head turn. Eye movement recordings have made it possible to accurately determine the amount of surgery required and to predict acuity increases even when undetectable during the preoperative clinical examination.
在三例先天性眼球震颤患者中，术前和术后均使用精确的眼球运动记录法研究了不同注视角度下的眼球震颤强度。除了使眼球震颤的中和点发生移位外，手术还扩大了中和区域，并导致所有注视角度下的眼球震颤强度总体降低。手术性旋转还使所有病例的视力得到改善。0度时的术后视力优于术前0度以及患者偏好注视角度（即术前中和角度）时的视力。这不仅适用于两名通过转头使术前视力得到改善的患者，也适用于一名其偏好的转头并未使术前视力显著改善的患者。眼动记录使得即使在术前临床检查中无法检测到时，也能够准确确定所需的手术量并预测视力提高情况。
