在3例先天性眼球震颤的患儿中，使用准确的眼球运动记录，研究了术前和术后不同注视角度下的眼球震颤强度。除了转移眼球震颤无效区之外，手术还扩大了无效区，并导致所有注视角度下眼球震颤强度的总体降低。手术旋转也导致所有病例的视力改善。术后视力0.在0.5 °时的视力均优于术前。以及患者的优选注视角度（即，术前零位角）。这不仅适用于2名患者，他们的头部转动显示出术前视力改善，而且适用于患者，其术前视力没有实质性改善，她的首选头部转动。眼动记录使得能够准确地确定所需的手术量，并且即使在术前临床检查期间无法检测到时也能够预测敏锐度的增加。
Nystagmus intensities at various gaze angles were studied preoperatively and postoperatively, using accurate ocular motility recordings, in 3 cases [children] of congential 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.degree. was better than the preoperative acuity at both 0.degree. and the patient''s preferred gaze angle (i.e., the preoperative null angle). This was true not only for the 2 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.
