| Outline of Final Research Achievements |
Retinal capillary non-perfusion area (NPA) in eyes with branch retinal vein occlusion (BRVO) is associated with retinal ischemia, which is a risk factor of vitreous hemorrhages and neovascular glaucoma due to neovascularization. However the quantitative measure of NPA is difficult. We found that the number of absolute scotoma in static perimetry in these eyes is significantly associated with the qualitatively assessed area of NPA. The results indicates that the number of absolute scotoma could be a quantitative measure of retinal ischemia.
