The ocular hypotensive effect of orally and intravenously administered sodium lactate was compared in rabbits with intravenously administered urea and orally administered glycerin. Oral administration of sodium lactate appeared to be more effective than oral administration of glycerin. Sodium lactate, intravenously, seemed to be equally effective as intravenous administration of urea at low dose levels and more effective at the high dose levels.
