Abstract:
Objective To investigate whether the extact of ginko biloba (EGb761) can protect the retinal ganglion cells (RGC) after acute high intraocular pressure induced retinal ischemia-reperfusion injury. Methods Thirty Sprague-Dawley rats were randomly divided into three groups. The negative control group, positive control group, treatment group were given normal saline 5 mL/kg, 1% erigeron breviscapus (vant) hand-mazz (EBHM) 5 mL/kg, 1% EGb761 5 mL/kg, respectively 2 hour after injury and every day after operation. Retinal ganglion cells were retrograde labeled by injection of 3% fluorogold (FG) into both side of superior colliculus 5 days before the death of the rats. Results The average survival rate of retinal ganglion cells were 61.46%, 72.73% and 76.20% in negative control group, positive control group and treatment group respectively. Conclusion EGb761 has neuroprotective effect on retinal ganglion cells in acute high intraocular pressure induced retinal ischemia-reperfusion injury.
