[Light and pattern ERG in advanced glaucoma].

Electroretinographic responses of 9 eyes severely affected by glaucoma showed a reduction in amplitude on stimulation with pattern reversal, but normal amplitudes following stimulation with light flashes. Thus, the pattern-reversal electroretinogram offers a further means of evaluating the function of retinal ganglion cells and their nerve fibers. In addition, the authors' results also suggest that flash and pattern-reversal electroretinograms are generated by different retinal structures.
