To investigate the performance of 10 MHz ultrasonography in detecting posterior lens capsule defects before traumatic cataract surgery.
This retrospective analysis includes patients with traumatic cataracts who underwent cataract surgery. Preoperative 10 MHz ultrasonography was performed to evaluate whether the posterior lens capsule was defective or intact, and the results were compared to the intraoperative findings. Sensitivity, specificity, positive predictive value, negative predictive value, accuracy, and kappa were calculated.
The study included 140 eyes of 140 patients. There were 68 eyes with closed-globe injuries and 72 eyes with open-globe injuries. The sensitivity, specificity, positive predictive value, negative predictive value, accuracy, and kappa of 10 MHz ultrasonography was 86.76%, 90.28%, 89.39%, 87.84%, 88.57% and 0.771, respectively. The accuracy was 86.11% and 91.18% in open-globe and closed-globe injury groups, respectively.
The accuracy of 10 MHz ultrasonography in evaluating the posterior lens capsule in traumatic cataracts is high. Preoperative 10 MHz ultrasonography would help to make an appropriate surgical plan.
探讨 10MHz 超声在创伤性白内障术前检测后囊膜缺陷的性能。
本回顾性分析纳入了行白内障手术的外伤性白内障患者。术前进行 10MHz 超声检查评估后囊膜是否存在缺陷，并将结果与术中发现进行比较。计算了灵敏度、特异性、阳性预测值、阴性预测值、准确性和kappa 值。
研究纳入了 140 例患者的 140 只眼。其中 68 只眼为闭合性眼球损伤，72 只眼为开放性眼球损伤。10MHz 超声的灵敏度、特异性、阳性预测值、阴性预测值、准确性和 kappa 值分别为 86.76%、90.28%、89.39%、87.84%、88.57%和 0.771。开放性和闭合性眼球损伤组的准确性分别为 86.11%和 91.18%。
10MHz 超声评估外伤性白内障后囊膜的准确性较高。术前 10MHz 超声有助于制定适当的手术计划。
