title: Electroretinographic signs of experimental chronic ischemia in the rabbit retina.
abstract: Chronic retinal ischemia was induced in rabbits by clamping the retrobulbar neurovascular pedicle of one eye. The other eye was used as a control. Electroretinograms (ERGs) were recorded for up to 32 weeks. The amplitude of the b-wave and of the oscillatory potentials showed a biphasic change: first a rapid drop below normal for 4 to 9 weeks, then an increase to above normal. The hyperresponsiveness was maintained up to the 32nd week. The implicit time of response was significantly modified only for the responses evoked by a low to moderate intensity of stimulation.
