According to the findings of Noma et al. [8, 13], the VEGF value of the vitreous humor in typical cases is 15.6 pg/ml in mild ischemia, 30–40 pg/ml in mild no perfusion; 338 pg/ml in moderate ischemia, 300 pg/ml or higher in moderate no perfusion; 2570 pg/ml for severe ischemia, and 2000–3000 pg/ml for severe non-perfusion. The gene discussed is VEGFA; the disease is ischemia.
