眼球内铁质异物对眼组织的破坏作用早已为人熟知。在玻璃体出血时,血红蛋白降解也可释放出铁离子。近年的动物实验虽已证实玻璃体出血对视网膜没有直接的毒害作用,但是,血液可使玻璃体变性液化。这一改变是否归因于血液释放出的铁离子的作用,尚不清楚。在以往的铁锈症和玻璃体出血实验研究中,都很少注意铁离子对玻璃体的影响。本文采用离体实验方法,测 Eyeball foreign body damage to eye tissue has long been well known. During vitreous hemorrhage, hemoglobin can also release iron ions from degradation. In recent years, animal experiments have confirmed that vitreous hemorrhage on the retina is not directly toxic, but the blood can make glass degeneration liquefaction. Whether this change is due to the role of iron ions released by the blood is unclear. In the previous experimental study of rust disease and vitreous hemorrhage, little attention was paid to the effect of iron ion on the vitreous. In this paper, in vitro methods, measured
