目的 观察青少年型视网膜劈裂症的荧光素眼底血管造影 (FFA)与光相干断层扫描 (OCT)图像特征。 方法 对临床诊断为青少年型视网膜劈裂症的 7例 14只眼拍摄彩色眼底图像 ,其中 5例 10只眼进行 FFA检查 ,6例 12只眼进行黄斑部 OCT检查。 结果 检眼镜检查黄斑部有微囊样改变的 8只眼 FFA表现为分布不均的颗粒状透见荧光 ,部分密集呈条状或块状 ,形态与眼底表现的微囊样改变无确定对应性 ;眼底检查 2只眼黄斑部表现为色素紊乱者 ,FFA表现为斑驳状荧光 ;3只眼颞下方劈裂的视网膜 FFA表现为程度不同的毛细血管扩张 ,片状无灌注区 ,劈裂起始处可见斑驳状荧光。OCT检查显示黄斑部神经上皮层增厚 ,层间分离 ,呈大小不等的囊样低反光区。 结论 青少年型视网膜劈裂症黄斑部视网膜劈裂处有色素上皮的增生与脱失 ,FFA表现为颗粒状透见荧光 ,OCT表现为囊样低反光区。
Objective To observe the features of fluorescein fundus angiography (FFA) and optical coherence tomography (OCT) images of adolescent retinoschisis. Methods Color fundus images were obtained from 7 eyes (7 eyes) diagnosed as juvenile retinoschisis. FFA was performed in 5 of 10 eyes and macular OCT in 6 eyes of 12 eyes. Results In the ophthalmoscopy, 8 eyes with micro-cystic changes in the macula showed irregular distribution of granular FFA and some were densely arranged in strips or lumps. There was no definite correspondence between morphology and microcirculation of the fundus ; Fundus examination showed macular macular degeneration in 2 eyes, FFA showed mottled fluorescence; retinal FFA in the temporal fissure of 3 eyes showed different degrees of telangiectasia, non-perfusion region, initiation of cleavage Spot visible mottled fluorescent. OCT examination showed that the macular nerve epithelial thickening, layer separation, showed varying sizes of cystic low reflex zones. Conclusion There are hyperplasia and degeneration of the pigment epithelium in the retina of the retina of adolescent type. The appearance of FFA is grainy, while OCT is cystic low reflex.
