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 investigate the characteristics of optical coherence tomography (OCT) images of macrophage proliferative membrane and its clinical value and postoperative evaluation. Methods OCT examination was performed in 38 cases of 38 patients with macular retina suspected or diagnosed as retinas in our fundus before and after operation. Results The macular retinal pre-ocular membrane OCT images showed the thickness of the retinal surface of the high reflective tape, or close to the macular surface, or with its part connected. Most foveal fovea shallow, increasing thickness. Postoperative macular retinal anterior membrane disappeared, macular area in some cases pigment epithelial damage or macular edema. Conclusions OCT can directly and objectively display the changes of various tissues and structures of the macular and macular, and provide more accurate and reliable information for the clinical diagnosis, operation and evaluation of the macular.
