摘要
光学相干断层扫描(opticalcoherencetomography,OCT)是一种非损伤性、非接触性、对视网膜细微结构进行横截面扫描的新的影像学检查方法,能清晰显示视网膜不同层次的结构并能对视网膜的细微结构进行客观、定量的测量和分析。黄斑区是视觉最敏感的部位,发生在这一区域的病变,即使很微小,也会对视力造成严重的影响。利用OCT的高分辨性观察高度近视后巩膜葡萄肿视网膜劈裂的特征性表现,对监测高度近视黄斑区的病变有独到的价值,同时能指导临床诊断、预测手术方式。
Optical coherence tomography（OCT） is a noncontact , noninvasive technique for examination of the human retina used to image tissue in high resolution cross-section. OCT can show the structure of different lays in the retinal and offer quantitative,objective analysis and measure. Macula is the most sensitive area of the vision. Any small change in this area will cause in severely affection to vision. OCT imaging of the retinoschisis in high myopia with posterior staphyloma may have a special value for the diagnosis and the monitoring of macular disease in high myopia, and direct the diagnosis and calculate the methods of the operation.
