To describe the peripheral autofluorescence images and clinical features of patients with retinal dystrophy who showed radial fundus autofluorescence (FAF) at the posterior pole.
The authors retrospectively reviewed pooled wide-field FAF images of 711 patients with retinal dystrophy and 56 family members.
Eleven eyes of seven women exhibited radial FAF at the posterior pole. Wide-field FAF showed extension of the radial pattern to the periphery in all eyes except one. One woman showed radial hyper-FAF only in the periphery, not at the posterior pole. These eight individuals were X-linked retinitis pigmentosa patients or carriers. The tapetal-like reflex was not observed in their color fundus photographs. The peripheral visual field showed wedge-shaped restriction in some individuals.
Wide-field FAF imaging can depict radial FAF not only at the posterior pole but also in the periphery in X-linked retinitis pigmentosa carriers. The authors therefore agree with previous reports that radial FAF may be a hallmark of X-linked retinitis pigmentosa.
描述后极部出现放射状眼底自发荧光（FAF）的视网膜营养不良患者的周边自发荧光图像及临床特征。
作者回顾性分析了711例视网膜营养不良患者及56名家庭成员的广角FAF图像。
7名女性的11只眼后极部出现放射状FAF。除1只眼外，广角FAF显示所有眼睛的放射状模式均延伸至周边。1名女性仅周边出现放射状高自发荧光，后极部未出现。这8名个体为X连锁视网膜色素变性患者或携带者。其彩色眼底照片中未观察到毯样反光。部分个体周边视野呈楔形缺损。
广角FAF成像不仅可显示X连锁视网膜色素变性携带者后极部的放射状FAF，还可显示周边的放射状FAF。因此，作者认同既往报道，即放射状FAF可能是X连锁视网膜色素变性的一个标志。
