Abstract：
Background: Swept-source anterior segment optical coherence tomography (SS-AS-OCT) is a suitable examination for the vitreolenticular interface. Methods: In a prospective study using Anterion (Heidelberg Engineering, Heidelberg, Germany), 102 eyes of 102 patients were examined in pupil dilation, preoperatively and 6 times over 1-year follow-up. Preoperatively anterior hyaloid membrane (AHM) visibility was determined with Imaging App with high reliability. Postoperatively capsular bag-AHM distance was measured on six points by using Metrics App. Results: The AHM was visible in 18.6% preoperatively and postoperatively as well (Group 1), 49% of the preoperatively adherent AHMs became visible (Group 2A), 32.4% remained attached (Group 2B). Group 1: the average deepest point on the first day was 782.5 ± 324.1 microns, and it significantly differed from the later follow-up values. Group 2A: the average deepest value was 184.1 ± 220.1 microns, and there was no statistically significant difference between the postoperative visit values. The difference between the groups was statistically significant at every location and at each time point. Conclusions: AS-SS-OCT can be used to check BS both preoperatively (with limitations) and postoperatively.
摘要：
背景：扫描源眼前节光学相干断层扫描（SS-AS-OCT）是玻璃体晶状体界面的合适检查。方法：在一项使用Anterion的前瞻性研究中(海德堡工程，海德堡,德国),102例患者的102只眼进行了瞳孔扩张检查，术前随访6次超过1年。术前前透明膜（AHM）的可见性通过ImagingApp以高可靠性确定。使用MetricsApp在六个点上测量术后囊袋-AHM距离。结果：AHM在术前和术后可见18.6%（第1组），49％的术前粘附AHM变得可见（2A组），32.4%保持依附(2B组)。第1组：第一天的平均最深点是782.5±324.1微米，与后来的随访值明显不同。2A组：平均最深值为184.1±220.1微米，术后访视值差异无统计学意义。各组之间的差异在每个位置和每个时间点都具有统计学意义。结论：AS-SS-OCT可用于术前（有局限性）和术后的BS检查。
