Although urea is popular currently for this purpose, it is not free of certain disadvantages.Therefore, mannitol, an osmotic diuretic, was studied clinically to determine if it might be a more acceptable drug for ophthalmic use.

Materials and Methods  The mannitol was supplied as a 20% solution.* The 17 patients included in this study received a total number of 27 separate intravenous infusions of mannitol.
