光学相干断层扫描用于黄斑前膜临床诊治的探讨

Clinical Application of Optical Coherence Tomography in Patients with Epiretinal Membranes of the Macular

目的 探讨黄斑区增殖膜的光学相干断层扫描 (OpticalCoherenceTomographyOCT)图像特征及临床诊断和术后评估价值。方法 对在我院眼底检查拟诊或诊断为黄斑部视网膜患者 3 8例 3 8眼术前及术后行OCT检查。结果 黄斑部视网膜前膜的OCT图像表现为视网膜表面厚薄不一的高反光带 ,或紧贴于黄斑表面 ,或与其部分相连。绝大多数黄斑中心凹变浅 ,厚度增加。术后黄斑区视网膜前膜消失 ,部分病例黄斑区色素上皮损害或黄斑部水肿。结论 OCT可以直接客观地显示黄斑前膜及手术后黄斑部各种组织结构的改变 ,为黄斑前膜的临床诊断、手术效果及治疗评价提供了更加准确可靠的信息。

Objective To explore the image characteristics and clinical application of the optical coherence tomography (OCT) in patients with epiretinal membranes of the macular(ERMM). Methods 38 patients, who were diagnosed as or suspected as ERMM, were examined with OCT before and after operation from November, 2002 to October, 2003 in our hospital. Results Macular epiretinal membranes were visible on OCT as high reflective tissues, which were thin or thick, and contiguous to or anterior to the retinal surface. In most fovea, the depth decreased and the thickness increased. ERMM disappeared after operation. Conclusion OCT can display the macular epiretinal membrane and the pathological changes of macular tissues before and after operation. OCT can provide accurate information on the clinical diagnosis and operative efficacy of ERMM.
