Aims To investigate the structure of multilayered pigment epithelial detachment (m-PED) in neovascular age-related macular degeneration, and its association with visual prognosis and the progression of fibrotic scars at 12 months. Methods We retrospectively analysed 68 eyes of 63 patients with m-PED that included a prechoroidal cleft. The compartments within m-PED were divided into neovascular tissue (layer 1), a hyper-reflective band (layer 2), and a prechoroidal cleft (layer 3). Clinical variables were compared between patients manifesting layer 2 and those who did not. Multiple regression analyses were used to find the factors related to visual outcome and fibrotic scar formation. Results Layer 2 was detected in 38 (55.9 %) of 68 eyes. With continuous treatment, the group with layer 2 showed gradual visual deterioration (p<0.001 at month 12), while the group without layer 2 showed visual improvement (p<0.001 at month 12). In the group with layer 2, the thickness of layer 2 significantly increased, and in the group without layer 2, if it formed, it increased gradually (p=0.004 at month 12). In both groups, other layers significantly decreased by month 12. The presence of layer 2 at baseline was significantly associated with a poor visual outcome (p=0.009) and fibrotic scar formation (p=0.023). Conclusions The m-PED with layer 2 had a higher risk of fibrotic scar formation and was associated with a poor visual prognosis. Layer 2 may be an early stage precursor of a fibrotic scar. Data are available on reasonable request.

老年性黄斑变性多层色素上皮脱离的形态学特征及预后意义

目的探讨新生血管性年龄相关性黄斑变性中多层色素上皮脱离(m-PED)的结构及其与视力预后和12个月时纤维化瘢痕进展的关系。方法 我们回顾性分析了包括脉络膜前裂的 63 名 m-PED 患者的 68 只眼。m-PED 内的隔室分为新生血管组织(第 1 层)、高反射带(第 2 层)和脉络膜前裂(第 3 层)。比较表现第 2 层的患者和没有表现出第 2 层的患者的临床变量。多元回归分析用于寻找与视觉结果和纤维化疤痕形成相关的因素。结果 68 只眼睛中有 38 只 (55.9 %) 检测到第 2 层。随着持续治疗,第 2 层组的视力逐渐下降(第 12 个月时 p<0.001),而没有第 2 层的组则显示出视觉改善(第 12 个月时 p<0.001)。在有第2层的组中,第2层的厚度显着增加,在没有第2层的组中,如果它形成,它会逐渐增加(第12个月p=0.004)。在两组中,其他层在第 12 个月时显着减少。基线时第 2 层的存在与视力不佳 (p=0.009) 和纤维化瘢痕形成 (p=0.023) 显着相关。结论 具有第 2 层的 m-PED 具有较高的纤维化瘢痕形成风险并且与较差的视觉预后相关。第 2 层可能是纤维化疤痕的早期前兆。可根据合理要求提供数据。在没有第 2 层的组中,如果它形成,它会逐渐增加(第 12 个月时 p=0.004)。在两组中,其他层在第 12 个月时显着减少。基线时第 2 层的存在与视力不佳 (p=0.009) 和纤维化瘢痕形成 (p=0.023) 显着相关。结论 具有第 2 层的 m-PED 具有较高的纤维化瘢痕形成风险并且与较差的视觉预后相关。第 2 层可能是纤维化疤痕的早期前兆。可根据合理要求提供数据。在没有第 2 层的组中,如果它形成,它会逐渐增加(第 12 个月时 p=0.004)。在两组中,其他层在第 12 个月时显着减少。基线时第 2 层的存在与视力不佳 (p=0.009) 和纤维化瘢痕形成 (p=0.023) 显着相关。结论 具有第 2 层的 m-PED 具有较高的纤维化瘢痕形成风险并且与较差的视觉预后相关。第 2 层可能是纤维化疤痕的早期前兆。可根据合理要求提供数据。结论 具有第 2 层的 m-PED 具有较高的纤维化瘢痕形成风险并且与较差的视觉预后相关。第 2 层可能是纤维化疤痕的早期前兆。可根据合理要求提供数据。结论 具有第 2 层的 m-PED 具有较高的纤维化瘢痕形成风险并且与较差的视觉预后相关。第 2 层可能是纤维化疤痕的早期前兆。可根据合理要求提供数据。
