31 patients with bilateral fourth nerve palsies are considered in this paper, 25 of the cases being traumatic in origin. Quantitative estimation of the torsional defect is carried out, using special synoptophore slides and a modification of the Lees' screen technique. Inability to prove the patient's retention of fusion in the presence of torsion is discussed. Although many of the traumatic cases had been rendered unconscious for varying periods of time up to several weeks by the initial injury with the known risk of losing fusion, sixteen out of seventeen patients undergoing surgery for their diplopia had postoperative evidence of binocular single vision.
本文纳入了31例双侧第四神经麻痹患者，其中25例为外伤性。使用特殊的同视机幻灯片和改良的利斯屏技术对扭转缺陷进行定量评估。文中讨论了在存在扭转的情况下无法证明患者保持融合的问题。尽管许多外伤性病例因初始损伤而在不同时间段内失去意识长达数周，存在失去融合的已知风险，但接受复视手术的17例患者中有16例术后有双眼单视的证据。
