I investigated the pathogenesis of diabetic macular edema (DME) using optical coherence tomography (OCT). I established a novel methods for the segmentation of inner and outer retinal layers, following the measurements of these layers. Second, I performed the comparative study about the mechanisms of distrubance in foveal photoreceptor, and found the association between hyperreflective foci, external limiting membrane, the junction of inner and outer segments of photoreceptor cells. In addition, I demonstrated the pathogenesis of the development of serous retinal detachment and foveal cystoid spaces, depending on either retinal vascular hyperpermeability in the perifovea or the retinal vascular changes in the fovea or parafovea.Finally, we applied self-organizing map for the analyses of multi-dimensional data, and showed novel associations and dissociations of OCT findings or parameters, and proposed a novel classification of morphological patterns in dmabetic macular edema

我使用光学相干断层扫描（OCT）研究了糖尿病性黄斑水肿（DME）的发病机理。我建立了一种新的方法，用于按照这些层的测量进行分割内部和外部视网膜层。其次，我进行了有关凹入光感受器分解机制的比较研究，并发现过度反射灶，外部极限膜，光感受器细胞的内部和外部段的连接。此外，我证明了浆液性视网膜脱离和卵泡囊性空间的发展的发病机理，具体取决于视网膜血管过度透露率在perifovea或Fovea或parafovea中的视网膜血管变化。提出了DMABETIC黄斑水肿中形态模式的新型分类
