Changes in the Viscosity of Rabbit's Vitreous Humor Induced by Infusion of Urea

ABSTRACT

The viscosity of rabbit's vitreous filtrate was measured after intra-venous infusion of 30% urea in 10% glcuose solution and 10% glucose solution. The dosage administered was 1g per kg of body weight. As shown in table, the relative viscosity increased after infusion of urea and glucose solution and no difference was found in the extent of increase in viscosity between urea- and glucose-treated groups. The mechanism of viscosity increase and its relation to the intra-ocular pressure were discussed.
