Purpose: Evaluating pain after scleral buckling surgery with or without ropivacaïne sub–tenon injection at the end of procedure. Methods: 48 eyes of 48 patients with retinal detachment underwent scleral buckling by the same surgent with systematic peribulbaire anesthesia.The same procedure was realised :cryotherapy on tears and ponction just before scleral bucling.Patients were randomly assigned to have 0.2ml ropivacaïne sub–tenon injection in infero–temporal quadrant at the end of procedure (groupe 1=24), or nothing (groupe 2=24). At 6h, 12h, 24h with EVA (evaluation visual analogic), pain was evaluated by an expert who didn’t know the patients and their treatment. The same post–operative analgesic was given for groupe 1 and 2. Results:Significant differences were detected between the two groupes at 6h (p=0.0018), and 12h (p=0.03). No significant differences were detected between the two groupes at 24h (p=0.48). Evaluation visual analogic at 6h was 2.8±0.46 in groupe 1 and 5.3±0.40 in groupe 2, EVA at 12h was 2.3±0.42 in groupe 1 and 3.83±0.44 in groupe 2. EVA at 24h was 2.5±0.34 in groupe 1 and 3 ±0.53 in groupe 2. Conclusions: According to this study and to reduce pain, we propose, when it is possible, ropivacaïne sub–tenon injection at the end of procedure after scleral buckling surgery.
