[Retinal neuronal relationships in health and in optic neuropathy of glaucomatous genesis].
A new procedure is proposed to study oscillatory potentials (OP), by using long-term flash ERG. OPs for on- and off-ERG were isolated, by employing mathematical filters (80-200 Hz). This procedure was used to examine 25 healthy subjects and 40 patients with different stages of glaucoma. The procedure could ascertain the site of a pathological process in the on- or off-cone cell system, each showing a different sensitivity. The use of this study opens up new avenues for the study of both pathological processes in the on- and off-cone cell systems from distal to proximal portions and pathogenetic mechanisms responsible for development of retinal and optic nerve diseases.
