Abstract

Objective To observe the changes of ERG b wave after ischemia and reperfusion.Methods Retinal ischemia was induced in rabbits by increasing intraocular pressure to 16kPa for 60 minutes and the ERG b wave was examined 2、7、14 days after retinal ischemia and reperfusion respectively.Results The b wave began to fall down from the second day after ischemia and reperfusion,which was (42.3±1.2)%( ±s ) of the pre ischemia value,and then b wave amplicude reduced persistly and progressively.Conclusion Injury followed reperfusion after ischemia in rabbit retina was persist and progressive.
