A prospective study was carried out of the evaluation preoperative prism adaptation in 77 patients with acquired esotropia. Sixty-three patients who showed a stable esodeviation with prisms of 10 prism diopter or less by alternate prism cover test and fusion response to the prisms were classified as prism responders and were randomly classified into two groups. Thirty-one patients of prism responders underwent surgery based on the prism adapted angle. Patients in the other 32 cases were assigned to undergo surgery for their initially measured angle. On the other hand, 14 patients who did not respond to prism adaptation underwent surgery for their preoperative measured angle of deviation. Success rates with deviations of 0 to 10 prism diopters measured 1 year after surgery by the alternative prism cover test at 5 m and with fusion on Bagolini's striated glasses test were highest (26 [84%] of 31 patients) in prism adaptation responders who underwent surgery for prism determined angle and lowest (3 [21%] of 14 patients) in the prism adaptation nonresponder who showed no fusion response to the prisms.
对77例后天性内斜视患者进行了术前棱镜适应评估的前瞻性研究。通过交替棱镜遮盖试验，63例患者使用10棱镜度或更小的棱镜时表现出稳定的内斜视偏差，且对棱镜有融合反应，这些患者被归类为棱镜反应者，并随机分为两组。31例棱镜反应者根据棱镜适应角度接受手术。其他32例患者则根据最初测量的角度接受手术。另一方面，14例对棱镜适应无反应的患者根据术前测量的斜视角度接受手术。术后1年，在5米处通过交替棱镜遮盖试验测量，偏差为0至10棱镜度且在巴戈利尼线状镜试验中有融合的成功率，在根据棱镜确定角度接受手术的棱镜适应反应者中最高（31例患者中有26例[84%]），在对棱镜无融合反应的棱镜适应无反应者中最低（14例患者中有3例[21%]）。
