玻璃体黄斑牵引综合征的临床及光相干断层 扫描图像特征

目的观察玻璃体黄斑牵引综合征的光相干断层扫描（OCT）图像特征及临床意义。方法回顾分析经OCT、荧光素眼底血管造影及B型超声检查确诊并经手术证实的25例玻璃体黄斑牵引综合征患者的临床资料，观察玻璃体黄斑牵引综合征的OCT图像特征。结果玻璃体黄斑牵引综合征的OCT图像主要表现为玻璃体反射光带牵拉视网膜，25例大致可分为5种特征，其中，玻璃体黄斑牵引综合征合并黄斑囊样水肿10例，玻璃体黄斑牵引综合征合并视网膜脱离5例，玻璃体黄斑牵引综合征合并黄斑裂孔3例，玻璃体黄斑牵引综合征合并黄斑视网膜前膜6例，玻璃体黄斑牵引综合征合并黄斑劈裂1例。结论玻璃体黄斑牵引综合征的OCT图像主要表现为玻璃体反射光带牵拉视网膜；OCT检查对玻璃体黄斑牵引综合征的诊断及追踪病情发展有重要作用。(中华眼底病杂志,2005,21:86-89)

Clinical characteristics and features of images of optical coherence tomography in vitreomacular traction syndrome

Objective To observe the characteristics of the images of optical coherence tomography (OCT) performed on the patients with vitreomacular traction syndrome and its clinical significance. Methods The clinical data of 25 patients with vitreomacular traction syndrome diagnosed by OCT, fundus fluorescein angiography, and B-scan ultrasonography and confirmed by surgical treatment were retrospectively analyzed. The features of images of OCT in vitreomacular traction syndrome were observed. Results Five types were found in the images of OCT in the patients with vetreomacular traction syndrome. The main characteristic of the images of OCT in the patients with vitreomacular traction was the highly reflective band of the vitreous posterior cortex inservion at fovea. In 25 patients, vitreomacular traction associated with macular edema was found in 10, macular hole in 3, macular epiretinal membrane in 6, retinoschisis in 1, and retinal detachment in 5. Conclusion OCT is a potential powerful toll for detecting and monitoring vitreomacular traction syndrome.
