| 摘 要： | 目的：观察地塞米松对犬视网膜超微结构的影响。方法：取犬4只，右眼玻璃体和房水内注射盐水(为盐水组)，左眼玻璃体和房水内注射地塞米松(为激素组)，24h后处死，电镜观察视网膜超微结构有无改变，并与对照组进行比较。结果：盐水组和激素组与对照组比较视网膜超微结构无改变。结论：地塞米松对犬视网膜超微结构无影响。，Objective:To observe the influence of dexamethasone on dog＇s retina ul-trastructure. Methods:We injected normal saline into the vitreous body and aqueous humor ofthe right eyes while injecting dexamethasone into the left eyes in four dogs. After 24 hours, wekilled the dogs to observe ff their retina ultrastructure had altered, and compared with the re-sults of the control group. Results :In comparision with the control group,there was any changein retina ultrastructure in neither the normal saline group nor the hormone group. Conclusion:Dexamethasone has no influence on the retina uitrastructure of dogs.
