PURPOSE
To highlight a potential pathogenetic mechanism of retinal arterial macroaneurysm.
OBSERVATIONS
A 79-year-old woman presented with a ruptured retinal arterial macroaneurysm in the right eye. One year after treatment, high-resolution multimodal imaging with optical coherence tomography (OCT), OCT angiography, and adaptive optics scanning light ophthalmoscope showed that a narrow passage developed in the vessel wall of the pre-existing retinal arterial macroaneurysm and another macroaneurysm had developed adjacent to the pre-existing one.
CONCLUSIONS AND IMPORTANCE
These images suggest the pathogenesis of retinal arterial macroaneurysm (RAM) associated with crack-like changes in the retinal arterial wall, similar to pathologies seen in systemic arteries.
目的
强调视网膜动脉大动脉瘤潜在的发病机制。
观察结果
一名79岁女性右眼出现视网膜动脉大动脉瘤破裂。治疗一年后，光学相干断层扫描（OCT）、OCT血管造影和自适应光学扫描激光检眼镜的高分辨率多模态成像显示，先前存在的视网膜动脉大动脉瘤的血管壁出现狭窄通道，且在先前存在的动脉瘤附近又出现了一个大动脉瘤。
结论及重要性
这些图像提示视网膜动脉大动脉瘤（RAM）的发病机制与视网膜动脉壁的裂纹样改变有关，类似于在体循环动脉中所见的病理情况。
