To find the accuracy of Scheimpflug imaging for the evaluation of posterior lens capsule and to assess the incidence of pre-existing posterior capsular tear (PCT) in pediatric traumatic cataracts.
It was a prospective, non-randomized, and interventional study. Scheimpflug imaging was done preoperatively to detect pre-existing PCT in pediatric traumatic cataracts after blunt trauma. All patients underwent cataract extraction with intraocular lens implantation. Intraoperatively, the posterior capsule status was noted and compared with the preoperative Scheimpflug images.
Forty-seven eyes of 47 children having traumatic cataracts following closed-globe injury were included. There were 32 males and 15 females with a mean age of 10.91 ± 2.75 years. The mean duration of performing the Scheimpflug imaging from injury was 41.7 ± 7.78 days. Preoperative Scheimpflug imaging showed intact posterior lens capsule in 36 eyes and PCT in 11 eyes. Intraoperative, 37 eyes had an intact posterior lens capsule and 10 eyes had PCT. The Scheimpflug imaging did not detect the PCT in three eyes (false-negative), and in four eyes, PCT was detected falsely on Scheimpflug imaging (false-positive). The sensitivity and specificity of the Scheimpflug imaging were 70 and 89.18%, respectively. The accuracy of the technique was 85.11%.
Scheimpflug imaging is a useful modality for the detection of PCT preoperatively in cases with doubtful posterior lens capsule integrity.
评估 Scheimpflug 成像在评估后囊膜中的准确性，并评估儿童外伤性白内障中存在的后发性白内障（PCT）的发生率。
这是一项前瞻性、非随机、干预性研究。Scheimpflug 成像术用于评估钝性外伤后儿童外伤性白内障中是否存在先前存在的后发性白内障。所有患者均行白内障超声乳化吸除联合人工晶状体植入术。术中观察后囊膜状态，并与术前 Scheimpflug 图像进行比较。
共纳入 47 例（47 只眼）闭合性眼球损伤后外伤性白内障患儿，男 32 例，女 15 例，平均年龄 10.91±2.75 岁。Scheimpflug 成像术从受伤到完成的平均时间为 41.7±7.78 天。术前 Scheimpflug 成像显示 36 只眼后囊膜完整，11 只眼后发性白内障。术中，37 只眼后囊膜完整，10 只眼后发性白内障。Scheimpflug 成像术漏诊 3 只眼（假阴性），4 只眼Scheimpflug 成像术误诊为后发性白内障（假阳性）。Scheimpflug 成像术的敏感性和特异性分别为 70%和 89.18%，准确率为 85.11%。
Scheimpflug 成像术是术前评估后囊膜完整性可疑病例中检测 PCT 的一种有用方法。
