Adult-onset foveomacular vitelliform dystrophy (AOFVD) is typically bilateral and symmetrical. We present the spectral optical coherence tomography (OCT) findings in two patients with unilateral AOFVD.
Case 1 represents a 76-year-old man followed angiographically over the last 6 years for a macular lesion in his right eye. Visual acuity in the right eye has decreased from 1.0 to 0.6. In case 2, a 69-year-old man presented with blurred vision in his right eye. Visual acuity was 0.7 in the right eye and 1.0 in the left eye. In both patients, spectral OCT (Copernicus SOCT System) was performed.
In case 1, fluorescein angiography showed a juxtafoveal hyperfluorescent lesion 2 / 3 of disc area in size, without late leakage. OCT showed a cystic oval lesion with thick walls, located between the retinal pigment epithelium (RPE) and photoreceptor layers. In case 2, OCT showed a hyperreflective round lesion also located between the RPE and photoreceptor layers, elevating the overlying inner retina.
Spectral OCT enables enhanced visualization of the retinal layers and provides useful information regarding the diagnosis and the exact location of AOFVD.
成人型黄斑中心凹卵黄样营养不良(AOFVD)通常为双侧对称。我们展示了两名单侧AOFVD患者的光谱光学相干断层扫描(OCT)结果。
病例1为一名76岁男性,在过去6年中因右眼黄斑病变接受血管造影随访。右眼视力从1.0下降至0.6。病例2为一名69岁男性,右眼出现视力模糊。右眼视力为0.7,左眼视力为1.0。两名患者均接受了光谱OCT(哥白尼SOCT系统)检查。
病例1中,荧光素血管造影显示一个位于黄斑旁的高荧光病变,大小为视盘面积的2/3,无晚期渗漏。OCT显示一个椭圆形囊性病变,壁较厚,位于视网膜色素上皮(RPE)和光感受器层之间。病例2中,OCT显示一个高反射圆形病变,也位于RPE和光感受器层之间,使上方的内层视网膜隆起。
光谱OCT能够增强视网膜各层的可视化,并为AOFVD的诊断和确切位置提供有用信息。
