To characterize the clinical features of a Japanese patient with macular degeneration in aceruloplasminemia.
The clinical features were evaluated by visual acuity measurements, fluorescein angiography, electroretinography, and kinetic visual field testing.
We observed a Japanese patient with macular degeneration in aceruloplasminemia. This patient also had diabetes mellitus and neurodegeneration. Ocular examination showed macular degeneration, which included yellow deposits around the macula area and no foveal reflex.
It has been reported that Japanese patients with aceruloplasminemia have atrophy of the retinal pigment epithelium in the midperipheral area and yellowish discoloration of the fundus. However, the retinal findings and results of fluorescein angiography in our case were very similar to those for a white patient. We suggest that retinal degenerations in Japanese patients with aceruloplasminemia have clinical variability. We believe that impairment of iron metabolism caused by iron overload in the retina led to retinal degeneration in this case.
描述一名患有无铜蓝蛋白血症并伴有黄斑变性的日本患者的临床特征。
通过视力测量、荧光素血管造影、视网膜电图和动态视野测试来评估临床特征。
我们观察到一名患有无铜蓝蛋白血症并伴有黄斑变性的日本患者。该患者还患有糖尿病和神经退行性变。眼部检查显示黄斑变性,包括黄斑区周围的黄色沉积物且无中心凹反射。
据报道,患有无铜蓝蛋白血症的日本患者在中周部区域存在视网膜色素上皮萎缩以及眼底发黄。然而,我们病例中的视网膜表现和荧光素血管造影结果与一名白人患者的非常相似。我们认为患有无铜蓝蛋白血症的日本患者的视网膜变性具有临床变异性。我们相信,在这种情况下,视网膜中铁过载导致的铁代谢受损导致了视网膜变性。
