  Objective: The study evaluated the influence of clonidine on Intraocular Pressure (IOP), quality of the block and postoperative analgesia, as an adjunct to peribulbar block for vitreoretinal surgery. Methods: Randomized, double-blind clinical trial, approved by the Research Ethics Committee, with 62 adults undergoing vitreoretinal surgery, under peribulbar block. They were randomly assigned to 2 groups: Control (0.875% ropivacaine) and Clonidine (0.875% ropivacaine+1 μg/kg clonidine). Ocular Anesthetic Scoring System, Ramsay sedation score, IOP and hemodynamic parameters were checked before, 5, 10 and 20 minutes after peribulbar block. Degree of akinesia (Nicoll Score) was tested 10 minutes after the block. Postoperative analgesia was assessed 30 minutes after surgery and 24 hours after block. Statistical analysis by Stude..
