Ascorbate-mediated oxygen consumption in the vitreous body. Oxygen consumption rate of human vitreous (n = 62, up to five measurements per sample) recorded for 2 hours at 35°C in the dark. Samples were divided into three groups: intact (n = 26), liquefied (n = 20), and postvitrectomy (n = 16). Hyperbolic regressions provide estimates for concentration-dependent rate of ascorbate-mediated oxygen consumption in the vitreous body (intact: a = 1.57, b = 27.48; liquefied: a = 0.68, b = 11.29; vitrectomy: a = 0.67, b = 11.89).
