| Outline of Final Research Achievements |
We found that white dots in the ultrawide field fundus photograph or no boundary between the nerve fiber layer and ganglion cell layer in the optical coherence tomography (OCT) are delineated within the nonperfused areas in diabetic retinopathy (DR). Further, we reported inner retinal spots with inverted OCT reflectivity as a novel lesion on OCT images. Further investigation using novel imaging devices, e.g., OCT angiography and adaptive optics scanning laser ophthalmoscope revealed the pathogenesis in the nonperfused areas and the circulation disturbance or thickened vascular walls. Novel parameters on fundus imaging allowed us to identify the predictors of the responsiveness to anti-VEGF treatment or ocular steroid injections in diabetic macular edema.
