This study aimed to assess the regularity of the choroidoscleral interface (CSI) using a novel parameter, CSI irregularity index, before and after epiretinal membrane (ERM) surgery. This study included 36 patients with idiopathic ERM who underwent pars plana vitrectomy and ERM removal. All subjects underwent ocular examinations at baseline and at 1, 2, 4, and 6 months after surgery. The regular contour of the CSI was found in 14 patients (38.9%); mean CSI irregularity index was 14.84 ± 11.01 in this group. The irregular contour of the CSI was found in 22 patients (61.1%); mean CSI irregularity index was 33.96 ± 20.64 in this group. The CSI irregularity index decreased gradually after ERM surgery, and was correlated with postoperative best-corrected visual acuity. The CSI irregularity index could serve as a surrogate marker to quantitatively represent the CSI morphology. We observed the gradual decrease of the CSI irregularity index after ERM surgery in quantitative manner. This study showed correlations between the CSI irregularity index and visual outcomes after ERM surgery. Our results suggest that the CSI irregularity index might be an intuitive anatomic indicator of the CSI and might be useful as a possible prognostic marker for patients undergoing ERM surgery.

脉络膜界面不规则指数：一种新的基于光学相干断层扫描的视网膜前膜患者参数。

这项研究旨在评估视网膜前膜（ERM）手术前后使用新参数CSI不规则指数评估脉络膜巩膜界面（CSI）的规律性。这项研究包括36例特发性ERM患者，他们接受了平面玻璃体切除术和ERM切除术。所有受试者均在基线以及手术后1、2、4和6个月接受眼科检查。在14名患者（38.9％）中发现了CSI的规则轮廓；该组的平均CSI不规则指数为14.84±11.01。22例患者（61.1％）发现CSI轮廓不规则；该组的平均CSI不规则指数为33.96±20.64。ERM手术后，CSI不规则指数逐渐降低，并与术后最佳矫正视力相关。CSI不规则指数可以用作替代指标，以定量表示CSI形态。我们观察到ERM手术后CSI不规则指数逐渐降低。这项研究显示了ERM手术后CSI不规则指数与视觉结果之间的相关性。我们的结果表明，CSI不规则指数可能是CSI的直观解剖指标，并且可能作为接受ERM手术的患者的可能预后指标。
