Abstract

Purpose: To identify preoperative clinical characteristics of macular hole (MH) formation after vitrectomy for submacular hemorrhage (SMH) due to ruptured retinal arterial macroaneurysm (RAM).

Methods: We retrospectively analyzed eyes with SMH due to ruptured RAM in patients who underwent vitrectomy and had more than one month of follow-up. We compared background factors and imaging findings between groups classified by MH presence. The primary outcomes were best-corrected visual acuity, and fundus and optical coherence tomography findings.

Results: We identified 48 eyes with SMH due to RAM rupture. MHs were identified in 8 eyes (16.3%); 4 intraoperatively and 4 postoperatively. Preoperative OCT findings revealed that all MH cases exhibited the highest retinal thickness at the foveal lesion with sub-internal limiting membrane (ILM) hemorrhage preoperatively. We termed this finding the "foveal mountain peak" (FMP) sign, characterized by sub-ILM hemorrhage where the peak of the retinal thickness coincides with the fovea. The incidence of FMP sign (+) cases was significantly higher in the MH (+) group compared with the MH (-) group (100% vs. 47.5%, respectively; P = 0.006).

Conclusion: The presence of the FMP sign may indicate an increased risk of SMH-associated MH.

张力作用下的内膜下眼窝出血：预测黄斑膜下出血后黄斑孔形成的 OCT 生物标志物

目的：确定视网膜动脉大动脉瘤（RAM）破裂导致的黄斑膜下出血（SMH）玻璃体切除术后黄斑孔（MH）形成的术前临床特征：我们回顾性分析了接受玻璃体切除术并随访一个月以上的视网膜动脉大动脉瘤破裂导致的SMH患者。我们比较了以MH存在情况分类的各组之间的背景因素和成像结果。主要结果是最佳矫正视力、眼底和光学相干断层扫描结果：结果：我们发现了 48 只由于 RAM 破裂而患有 SMH 的眼睛。8只眼睛（16.3%）中发现了MH，其中4只在术中发现，4只在术后发现。术前OCT检查结果显示，所有MH病例的眼窝病变处视网膜厚度最高，术前有内缘膜（ILM）下出血。我们将这一发现称为 "眼窝山峰"（FMP）征，其特征是内层限局膜（ILM）下出血，视网膜厚度的峰值与眼窝重合。FMP征（+）病例在MH（+）组中的发生率明显高于MH（-）组（分别为100% vs. 47.5%；P = 0.006）：结论：FMP征的出现可能预示着SMH相关MH的风险增加。
