Retinal arterial macroaneurysms (RAM) are characterized by a saccular or fusiform dilation of the retinal artery wall. An 84-year-old Caucasian woman with a medical history of poorly controlled hypertension was diagnosed with RAM in the left eye. Previous macular spectral-domain optical coherence tomography images from the patient were available for comparison. Near-infrared reflectance imaging (NIR-R), taken 3 years before, demonstrated a cuff-type thickening of the arteriolar vessel wall at the site of the current complicated RAM that had gone completely unnoticed. These findings suggest that NIR-R may contribute to the detection of early damage of the arterial wall that may predict arterial aneurysm formation in hypertensive patients.
视网膜动脉大动脉瘤（RAM）的特征是视网膜动脉壁呈囊状或梭形扩张。一名84岁的白种女性，有高血压控制不佳的病史，被诊断为左眼患有RAM。该患者之前的黄斑区光谱域光学相干断层扫描图像可供比较。3年前拍摄的近红外反射成像（NIR-R）显示，在当前复杂RAM所在部位的小动脉血管壁有袖套样增厚，而这一情况之前完全未被注意到。这些发现表明，NIR-R可能有助于检测动脉壁的早期损伤，而这种损伤可能预示高血压患者动脉动脉瘤的形成。
