The weight of the rabbit vitreous body is reduced by average clinical doses of hyperosmolar agents. The weight change is 2.7% with orally administered glycerol, and 3.7% and 3.9% with intravenously administered urea and mannitol respectively. This study substantiates the clinical observation that vitreous volume can be reduced by osmotic therapy.
