黄斑部先天性视网膜劈裂的光相干断层扫描观察

Optic coherence tomography for congenital juvenile macular retinoschisis

目的 观察黄斑部先天性视网膜劈裂的光相干断层扫描 (OCT)图像特征及其临床意义。 方法 回顾分析经直接检眼镜或前置镜检查、荧光素眼底血管造影 (FFA)、视网膜电图 (ERG)检查确诊的11例黄斑部先天性视网膜劈裂患者 2 0只眼的 OCT检查资料。 结果 OCT图像中 ,2 0只眼黄斑部均有位于视网膜中层的视网膜劈裂 ,中心凹处视网膜分为内外两层 ;旁中心凹处大致可分为劈裂部位的视网膜轻度增厚 ,视网膜被中间的腔隙分为厚度相近的内外两层以及劈裂部位的视网膜明显增厚 ,视网膜组织被两个腔隙分为 3层两种类型。 结论 黄斑部先天性视网膜劈裂的 OCT图像特征为视网膜中层的劈裂腔隙。 OCT检查对黄斑部先天性视网膜劈裂具有很高的敏感性。

Objective To observe the characteristics of images of optic coherence tomography (OCT) for the macular region of congenital retinoschisis and investigate its significance. Methods The data of OCT of 11 patients (20 eyes) with congenital macular retinoschisis diagnosed by direct or preplaced-mirror ophthalmoscopy, fundus fluorescein angiography (FFA), and electroretinography (ERG) were retrospectively analyzed. Results The images of OCT showed split in the mid portion of sensory retina at the macula in all eyes. The retina of fovea centralis was divided by the split into two slightly thickening layers. In addition, in a few number of cases, the parafoveal sensory retina which became much thickening with 2 splits, was divided into 3 layers. Conclusion The characteristic of images of OCT in macular congenital retinoschisis is the split cavity at the middle layer of the retina, and OCT has a high sensitivity in the diagnosis of congenital retinoschisis.
