儿童遗传性视网膜疾病的眼底自身荧光表现

摘要

Objective To observe the autofluorescence (AF) manifestation in children with hereditary retinal diseases. Methods The clinical data of 22 children (aged from 5 to 14 years) with hereditary retinal diseases were retrospectively analyzed. There were 8 children (16 eyes) with Best vitelliform macular dystrophy, 3 children (6 eyes) with Stargardt macular dystrophy, 3 children (6 eyes) with macular cone dystrophy, 5 children (10 eyes) with primary retinitis pigmentosa, and 3 children (6 eyes) with X-linked juvenile retinoschisis. The routine clinical examinations included present history, family history, visual acuity, silt-lamp microscopy, indirect ophthalmoscopy, color fundus photography and fundus autofluorescence angiography (FAF). Some patients received fundus fluorescein angiography (FFA),electroretinogram (ERG), electrooculogram (EOG), and ocular coherence tomography (OCT). The characteristics of AF in all the children were analyzed, and were compared with the images of color fundus and/or FFA. Results Symmetry round macular fluorescent weak or absent area was found in all Stargardt disease and cone dystrophy. Weak AF area with surrounded circular increased AF was found in 2 children (4 eyes) with cone dystrophy and 1 child (2 eyes) with Stargardt macular dystrophy. A central round area with regular or irregular intense AF was observed in Best vitelliform macular dystrophy. RP children showed increased AF out of the macular region. Cellular or granular strong AF was found in the fovea of 3 children (5 eyes) with X-linked juvenile retinoschisis. Conclusion The children with hereditary retinal diseases had special AF changes.%目的 观察儿童遗传性视网膜疾病的眼底自身荧光(FAF)特征.方法 回顾性分析22例临床资料完整、年龄5～14岁之问的遗传性视网膜疾病患儿的FAF检查结果.其中,Best卵黄样病变8例16只眼,Stargardt病3例6只眼,视锥细胞营养不良3例6只眼,原发性视网膜色素变性(RP)5例10只眼,X连锁青少年型视网膜劈裂症3例6只眼.仔细询问现病史及家族史,行视力、裂隙灯显微镜眼前节检查,间接眼底镜检查,彩色眼底像和FAF照相,其中部分患儿接受了荧光素眼底血管造影(FFA)、视网膜电流图、眼电图、光相干断层扫描检查.对上述患儿的FAF结果特征进行归纳总结,并与其眼底照相和/或FFA结果进行比较分析.结果 3例Stargardt病患儿的6只眼及3例视锥细胞营养不良患儿的6只眼FAF检查显示黄斑区可见对称性的圆形、近圆形弱荧光或荧光缺如区,2例视锥细胞营养不良患儿的4只眼及1例Stargardt病患儿的2只眼可见弱荧光或荧光缺如区外缘环以强荧光;Best卵黄样病变患儿黄斑区可见一个强度均匀或不均匀的强FAF病灶;RP患儿后极部视网膜FAF增强,黄斑区周围可见宽度不等的环形强荧光带,拱环区FAF正常;3例X连锁青少年型视网膜劈裂症患儿中5只眼中心凹部位FAF检查可见蜂窝或颗粒状强荧光.结论 Stargardt病及视锥细胞营养不良患儿黄斑区为近圆形弱荧光,部分病变区外缘环以强荧光;Best卵黄样病变患儿黄斑区为强度均匀或不均匀的强FAF病灶;RP患儿后极部视网膜FAF增强,拱环区FAF正常,黄斑区周围可见宽度不等的环形强荧光带;X连锁青少年型视网膜劈裂症患儿中心凹部位为蜂窝或颗粒状强荧光.
