[Visual electrophysiology in 101 children with encephalopathy].
The electrophysiological recordings (E.R.G. associated with C.V.E.P.) performed on 101 children suffering from encephalopathy of different origins demonstrate a trend towards retinal integrity for subjects with encephalopathy and no suspicion of acid-base disorders. However a functional macular deficiency is frequently observed in encephalopathy with suspicion of acid-base disorders (encephalopathy due to intracranial hypertension or cardio-vascular disorders or metabolic deficiencies with acid-base disturbance). In these cases, a common pathophysiological substratum with disturbance of the acute or chronic acid-base equilibrium has been assumed. Over a period of time, in fixed encephalopathy, the electrophysiological results reflect a real but slow maturation of the visual pathways.
