| Research Abstract |
1) Basic Research We have reported that fenofibrate and cilostazol cause vasodilation and that homocystein impairs endothelial function of isolated porcine retinal arterioles. In addition, we also have reported that retinal endothelium, by releasing vasoactive substances, contributes to RBF regulation during acute severe elevation of systemic blood pressure in in vivo cat model.
2) Clinical Study We have found that retinal blood flow was decreased in patients with type 2 diabetes and renal dysfunction and that systemic endothelial function was impaired in patients with branch retinal vein occlusion.
