| Abstract: | Objective: To observe the morphological changes of blood retinal barrier (BRB) after retinal moderate blast injury and the therapeutic effects of superoxide dismutase (SOD) and dexamethasone on them. Methods: After the model of retinal moderate blast injury was established in rabbits, the morphological changes of BRB and the therapeutic effects of SOD and dexamethasone on them were observed with colloidal lanthanum tracing. Results: A part of retinal pigment epithelium cells, rod cells and cone cells were damaged and slight damage of BRB as shown by the leakage of lanthanum tracing into retina was seen. SOD and large dosed dexamethason could remarkably abate the injury of the retina, shorten the course of recovery and improve the retinal function. Conclusion: SOD and large dosed dexamethason can exert marked therapeutic effects on retinal moderate blast injury. |
