Abstract

PURPOSE: To investigate the Bruch's membrane-retinal pigment epithelium (RPE) complex in pseudoxanthoma elasticum (PXE) by imaging techniques capable of visualizing deep retinal structures with high contrast. DESIGN: Prospective cross-sectional study. PARTICIPANTS: Patients with PXE, confirmed by mutation analysis, skin histopathologic examination, or both. METHODS: Sixteen patients were investigated by indocyanine green (ICG) and fluorescein angiography, confocal near-infrared (NIR) reflectance, and fundus autofluorescence imaging using a confocal scanning laser ophthalmoscope (Spectralis HRA-OCT; Heidelberg Engineering, Heidelberg, Germany). Composite digital fundus photography also was performed. MAIN OUTCOME MEASURES: Characterization and topographic distribution of abnormalities detected by retinal imaging. RESULTS: On late-phase ICG angiography, a central area of decreased fluorescence centered on the posterior pole was a characteristic finding in all patients. A second area characterized by increased fundus reflectivity on NIR reflectance imaging extended further into the periphery. A third and most eccentric area showed neither decreased ICG fluorescence nor increased fundus reflectivity. These 3 areas were separated by 2 transition zones, the second being the equivalent of peau d'orange. Angioid streaks did not extend into the third area. CONCLUSIONS: The abnormalities detected by this multimodal imaging approach suggest a centrifugal spread of the retinal pathologic features of the Bruch's membrane-RPE complex in PXE. Decreased fluorescence on late-phase ICG angiography is a consistent sign of retinal pathologic features in PXE. Bruch's membrane calcification may be the underlying cause for the increased reflectivity observed on NIR reflectance imaging. FINANCIAL DISCLOSURE(S): Proprietary or commercial disclosure may be found after the references.

摘要

目的:通过能够高对比度显示深层视网膜结构的成像技术,研究假性黄色瘤弹性组织营养不良(PXE)的布鲁赫膜-视网膜色素上皮(RPE)复合体。

设计:前瞻性横断面研究。

参与者:经突变分析、皮肤组织病理学检查或两者均证实的 PXE 患者。

方法:16 例患者接受了吲哚菁绿(ICG)和荧光素血管造影、共焦近红外(NIR)反射和共焦扫描激光检眼镜(Spectralis HRA-OCT;Heidelberg Engineering,Heidelberg,德国)眼底自发荧光成像检查。还进行了复合数字眼底摄影。

主要观察指标:视网膜成像检测到的异常的特征和拓扑分布。

结果:在晚期 ICG 血管造影中,所有患者的后极中央区域均出现特征性的荧光减弱区。第二个区域的特点是 NIR 反射成像上的眼底反射增加,进一步延伸到周边。第三个也是最偏心的区域既没有 ICG 荧光减弱,也没有眼底反射增加。这 3 个区域由 2 个过渡区隔开,第二个过渡区类似于橘子皮。血管样条纹没有延伸到第三个区域。

结论:这种多模态成像方法检测到的异常提示 PXE 中布鲁赫膜-RPE 复合体的视网膜病理特征呈离心性扩散。晚期 ICG 血管造影中荧光减弱是 PXE 中视网膜病理特征的一致表现。NIR 反射成像上观察到的反射增加可能是布鲁赫膜钙化的潜在原因。

利益冲突:参考文献后可能会发现专有或商业披露。
