Background To evaluate, in patients undergoing macula-off rhegmatogenous retinal detachment surgery (RRD), the correlation between preoperative optical coherence tomography (OCT) morphological features and postoperative visual acuity. Methods Retrospective interventional non-randomised clinical trial on 89 eyes of 89 patients undergoing pars plana vitrectomy for macula-off primary RRD at Policlinico Universitario Agostino Gemelli from 2020 to 2023. Preoperative 6×6 mm OCT B scans with Nidek Mirante (Nidek, Gamagori, Japan) were performed, collecting the following features: foveal involvement (fovea-on vs fovea-off), subretinal hyper-reflective points (HRPs), outer retinal corrugations (ORCs) and intraretinal cystic spaces (ICS) in the outer nuclear layer. The patients were followed in a 6-month follow-up to evaluate best-corrected visual acuity (BCVA) outcomes. Results Preoperative mean BCVA was 0.15±0.22 and improved to 0.29±0.3 decimals at 6 months (p<0.001). The presence of subretinal HRPs showed a significant negative impact on BCVA improvement in the univariate regression analysis (r=−0.264, p=0.024), as well as the presence of foveal detachment (r=−0.355, p=0.012). The other OCT features did not show a significant correlation with BCVA improvement: ORCs (r=0.072, p=0.257) and ICS (r=−0.020, p=0.734). In the multivariate regression analysis, the negative impact of foveal detachment was confirmed (r=−0.199, p=0.05) while the statistical significance of subretinal HRPs was lost (r=−0.135, p=0.105). Conclusions The negative impact of foveal involvement in a macula-off RRD was confirmed. Moreover, the presence of subretinal HRPs, as a possible indirect marker of inflammatory response extent, may act as a negative predictor for postoperative visual recover.

新发黄斑脱落孔源性视网膜脱离术前中心凹微观结构的 OCT 分析:视力预后因素



背景 为了评估接受黄斑脱落孔源性视网膜脱离手术 (RRD) 的患者,术前光学相干断层扫描 (OCT) 形态学特征与术后视力之间的相关性。方法 回顾性介入性非随机临床试验,于 2020 年至 2023 年在 Policlinico Universitario Agostino Gemelli 对 89 名接受睫状玻璃体切除术治疗黄斑脱落原发性 RRD 的患者的 89 只眼睛进行研究。使用 Nidek Mirante(Nidek,Gamagori,日本)进行术前 6×6 毫米 OCT B 扫描,收集以下特征:中央凹受累(中央凹打开与中央凹关闭)、视网膜下高反射点 (HRP)、视网膜外波纹 (ORC) 和视网膜内囊隙间隙 (ICS) 在外核层。对患者进行为期 6 个月的随访,以评估最佳矫正视力 (BCVA) 结果。结果 术前平均 BCVA 为 0.15±0.22,6 个月时改善至小数点后 0.29±0.3 分 (p<0.001)。在单变量回归分析中,视网膜下 HRP 的存在对 BCVA 改善有显着的负面影响 (r=-0.264,p=0.024),以及中心凹脱离的存在 (r=-0.355,p=0.012)。其他 OCT 特征与 BCVA 改善没有显著相关性:ORC (r=0.072,p=0.257) 和 ICS (r=-0.020,p=0.734)。在多变量回归分析中,确认了中心凹脱离的负面影响 (r=-0.199,p=0.05),而视网膜下 HRP 的统计学意义丢失 (r=-0.135,p=0.105)。结论 证实了中心凹受累对黄斑脱落 RRD 的负面影响。此外,视网膜下 HRP 的存在作为炎症反应程度的可能间接标志,可能作为术后视力恢复的负面预测因子。 试验注册号 [NCT05747144][1]。数据可应合理要求提供。[1]: /lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT05747144&atom=%2Fbjophthalmol%2F108%2F12%2F1743.原子
