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.

To investigate the relationship between autoimmune pathogenic mechanism of retinal pigmentation (RP) and syndrome patterns in traditional Chinese medicine.Erythrocytic C3b receptor rosette(RCR) and erythrocytic immunocomplex rosette(RICR), circulating immune complex (CIC) content and expression rate of human leukocyte antigen D receptor (HLA-DR) in T lymphocyte of peripheral blood were detected in 22 healthy volunteers (group A) and 52 cases of RP (group B).In group B,RCR and RICR were decreased and CIC content and expression rate of HLA-DR were increased compared with group A (P
