为了证实玻璃体出血对视网膜的毒性作用,进行了玻璃体出血后,眼内液中铁离子浓度及形态学改变的实验研究。研究发现实验组眼内液中铁离子浓度明显升高,与对照组相比,差异有显著性。同时,形态学观察,实验组视网膜上有巨噬细胞浸润,光感受器细胞内段及外段变性。证实铁离子及炎性细胞浸润可能是造成视网膜损伤的主要因素。
In order to confirm the toxic effects of vitreous hemorrhage on the retina, an experimental study on the concentration and morphological changes of iron ions in the intraocular fluid after vitreous hemorrhage was performed. The study found that experimental group intraocular fluid iron concentration was significantly increased, compared with the control group, the difference was significant. At the same time, morphological observation showed that there was macrophage infiltration on the retina in experimental group and degeneration of inner and outer photoreceptor cells. Confirmed that iron ions and inflammatory cell infiltration may be the main cause of retinal damage.
