Echographic studies of osmotic agents.
The effectiveness of osmotic agents, acetazolamide (Diamox), urea, glycerol, and mannitol, and massages (5 and 10 minutes) for inducing hypotony in rabbit eyes was evaluated by ultrasonography. Mannitol was found to have the greatest hypotonic effect followed closely by urea and glycerol, then acetazolamide. The difference between the 5 and 10 minute massages was negligible.
