[Electrophysiologic and histologic retinal changes after diethylene glycol administration].
The toxic effect of diethylene glycol on the retina was studied in white New Zealand rabbits. In a three-month study diethylene glycol dissolved in water was administered orally to groups of four rabbits at dose levels of 0 (control) and 4%. The ERG revealed a dose-dependent prolongation of the b-wave and a reduction in the photopic amplitudes of the a- and b-waves. In agreement with the electrophysiological findings the histologic study of the retina showed birefringent crystals predominantly in the inner nuclear cell layer. Oxalate seemed to be a metabolite of diethylene glycol, because aggregations of calcium oxalate crystals were deposited in the kidneys and livers of the animals.
