【摘要 】 目的 探讨先天性视网膜劈裂症的光学相干断层扫描(optical coherence tomography,OCT)图像特征及临床诊断价值。 方法 对临床拟诊或诊断为先天性视网膜劈裂症患者8例15只眼行OCT、直接检眼镜、眼底彩色照相检查，其中3例6只眼行视网膜电图(electroretinogram,ERG)及荧光素眼底血管造影(fundus fluorescein angiography,FFA)检查。 结果 先天性视网膜劈裂症的OCT图像表现为典型的黄斑区囊样改变，伴斜形或垂直的桥状组织相连；后极部视网膜神经上皮层之间分离，其间有桥状组织相连；纱膜样改变的OCT图像为内层神经上皮增厚，与外层神经上皮分离。 结论 OCT能在活体直观、清晰地显示先天性视网膜劈裂症中的视网膜神经上皮层组织结构的改变，为先天性视网膜劈裂症的临床诊断提供了一种有效的新的检测手段。

【Abstract 】 Objective To investigate the characteristics of congenital retinoschisis of optical coherence tomography(OCT) and its clinical application. Methods Eight cases(15 eyes) which were diagnosed as or suspected to retinoschisis in clinic were examined by OCT,direct ophthalmoscopy and color fundus photograph.Three cases(6 eyes) were examined by electroretinogram(ERG) and fundus fluorescein angiography(FFA). Results The typical characteristic OCT images of congenital retinoschisis were cystic maculopathy with tilted and vertical connective filaments,typical split in innner retinal layers in posterior retina and thickening of neurosensory retina with the split of outer retinal layers in membranous remnants. Conclusions OCT can display the characteristics of congenital retinoschisis.It is potentially useful as a new technique for the diagnosis of congenital retinoschisis.
