To investigate whether intraoperative retinal changes during epiretinal membrane (ERM) peeling affect anatomic or functional outcomes after surgery.
We measured retinal thickness using an intraoperative optical coherence tomography (iOCT) device in patients undergoing pars plana vitrectomy with membrane peeling for idiopathic ERM. Changes in intraoperative central macular thickness (iCMT) were compared with postoperative improvements in CMT and best-corrected visual acuity (VA).
Twenty-seven eyes from 27 patients (mean age 68 years) underwent iOCT-assisted ERM peeling surgery. Before surgery, mean VA was logMAR 0.50 ± 0.36 (Snellen 20/63), and mean baseline CMT was 489 ± 82 µm. Mean iCMT before peeling was 477 ± 87 µm, which correlated well with preoperative CMT (P < 0.001). Mean change in iCMT was -39.6 ± 37 µm (range -116 to +77 µm). After surgery, VA improved to logMAR 0.40 ± 0.38 (Snellen 20/50) at month 1 and logMAR 0.27 ± 0.23 (Snellen 20/37) at month 3, whereas CMT decreased to 397 ± 44 µm and 396 ± 51 µm at months 1 and 3. Eyes that underwent greater amount of iCMT change (absolute value of iCMT change) were associated with greater CMT reduction at month 1 (P < 0.001) and month 3 (P = 0.010), whereas those with greater intraoperative thinning (actual iCMT change) showed a trend toward better VA outcomes at months 1 (P = 0.054) and 3 (P = 0.036).
Intraoperative changes in retinal thickness may predict anatomic and visual outcomes after idiopathic ERM peeling surgery.
Our study suggests that intraoperative retinal tissue response to ERM peeling surgery measured by iOCT may be a prognostic indicator for restoration of retinal architecture and for visual acuity outcomes.
研究内界膜(ERM)剥除术中的视网膜变化是否会影响手术后的解剖或功能结果。
我们使用术中光相干断层扫描(iOCT)设备测量了接受特发性 ERM 经睫状体平坦部玻璃体切除术联合膜剥除术的患者的视网膜厚度。比较术中中央黄斑厚度(iCMT)的变化与术后 CMT 和最佳矫正视力(VA)的改善。
27 例(27 只眼)患者接受了 iOCT 辅助 ERM 剥除手术。术前平均 VA 为 logMAR 0.50 ± 0.36(Snellen 20/63),平均基线 CMT 为 489 ± 82µm。剥除前的平均 iCMT 为 477 ± 87µm,与术前 CMT 相关性良好(P < 0.001)。iCMT 的平均变化为-39.6 ± 37µm(范围-116 至+77µm)。术后 1 个月 VA 改善至 logMAR 0.40 ± 0.38(Snellen 20/50),术后 3 个月 VA 改善至 logMAR 0.27 ± 0.23(Snellen 20/37),而 CMT 分别降至 397 ± 44µm 和 396 ± 51µm。iCMT 变化绝对值较大的眼,1 个月(P < 0.001)和 3 个月(P = 0.010)时 CMT 降低更明显;术中变薄更明显的眼(实际 iCMT 变化),1 个月(P = 0.054)和 3 个月(P = 0.036)时 VA 改善趋势更明显。
