To compare final visual outcomes of surgically treated traumatic cataract between open-globe and closed-globe injuries in children, as classified by the Birmingham Eye Trauma Terminology system.
This is an observational cohort study with permission from Hospital Ethical Committee. We enrolled children meeting specific inclusion criteria, examined their eyes to review any co-morbidities due to trauma, performed surgery for traumatic cataracts, and implanted lenses. The patients were re-examined postoperatively. We classified the cases of traumatic cataract as either open-globe (Group 1) or closed-globe (Group 2) according to the Birmingham Eye Trauma Terminology system and compared visual acuity.
Our study cohort of 1076 eyes with traumatic cataracts included 405 eyes in Group 1 and 671 in Group 2. Postoperatively, the visual acuity was >20/60 in 223 (55.3%) and 377 (56.3%) operated eyes in Groups 1 and 2, respectively ( p < 0.001, analysis of variance). With further follow-up, >20/60 vision was significantly higher in Group 2 as compared to Group 1 (odds ratio = 1.61; 95% confidence interval = 0.85-3.02). Overall, 600 eyes (55.7%) regained final visual acuity >20/60.
Closed-globe injury has more favourable prognosis for the satisfactory (>20/60) visual recovery after effective management of traumatic cataracts in children.
根据伯明翰眼外伤术语系统，比较儿童开放性眼球损伤和闭合性眼球损伤手术治疗外伤性白内障的最终视力结果。
这是一项经医院伦理委员会批准的观察性队列研究。我们纳入符合特定纳入标准的儿童，检查他们的眼睛以评估因外伤引起的任何合并症，对外伤性白内障进行手术并植入晶状体。术后对患者进行复查。我们根据伯明翰眼外伤术语系统将外伤性白内障病例分为开放性眼球损伤（第1组）或闭合性眼球损伤（第2组），并比较视力。
我们的1076只外伤性白内障研究队列中，第1组有405只眼，第2组有671只眼。术后，第1组和第2组分别有223只（55.3%）和377只（56.3%）手术眼的视力>20/60（方差分析，p<0.001）。进一步随访发现，第2组视力>20/60的比例显著高于第1组（优势比=1.61；95%置信区间=0.85-3.02）。总体而言，600只眼（55.7%）恢复了最终视力>20/60。
对于儿童外伤性白内障进行有效治疗后，闭合性眼球损伤在实现满意（>20/
