Effect of Ziyinmingmuwan on Ultrastructure of Rat Retina with Retinal Photic Injury / 中国中医药信息杂志

Objective To investigate the protective effect and mechanism of Ziyinmingmuwan on retina against photic injury. Methods Seventy Sprague-Dawley (SD) rats were randomly divided into 7 groups, with 6 groups prepared as the models of phototrauma at first and another group taken as blank control. After three days, the animals in the treatment and control groups were treated with Ziyinmingmuwan and control agent respectively for 15 days during the period of experiment. Following this, the retinal tissues were examined by light and electron microscopy. Results The retinal lesions were repaired and the morphological structure of the retina was brought to normal gradually. Conclusion Ziyinmingmuwan could improve ultrastructure of the retina.
