Purpose:To investigate the effects of topical prazosin and pilocarpine on uveoscleral outflow(Fu) in rabbits.Methods:Sixteen rabbits were randomly divided into the control group (5 rabbits, only topical application of normal saline in the fight eye of each rabbit), Prazosin (PZ) treated group (6 rabbits, only 0.1％ Prazosin eyedrop 0.1％ in the right eye of each one) and Pilocarpine (PC) treated group (5 rabbits, 1％ Pilocarpine eye drop in each fight eye). Intraocular pressure (IOP) of bilateral eyes of each rabbit was measured before and 1h after topical application of the eye drop. And the bilateral eyes were perfused with Fluorescein-isothiocyanate bovine serum albumin (FITC-BSA) as the tracer into the anterior chamber of each rabbit for 30 min at 90 min after topical treatment. Then the rabbits were killed for Fu measurement.Results:IOP of PZ-treated eyes decreased [(0.71±0.07)kPa] in 1 hour after PZ application. IOP of PC-treated eyes decreased [(0.70±0.08)kPa] in 1 hour after PC application. Th
