M We have prospectively analqsed the feasibility and advantages of local anesthesia in surgical management of advanced proliferative vitreoretinopathy in retinal detachment (RD). M&Q& Peribulbar anesthesia (PBA) was used in 20 consecutive cases operated for RD. All the pateints requiered s&rat buckling, pars plana vitrectomy, complete membrane removal, endophotocoagulation and internal tamponad...

OBJECTIVE To examine the anatomic distribution of gadolinium contrast medium by high-resolution surface-coil magnetic resonance imaging after peribulbar and retrobulbar injection. METHODS Comparative case series in which 4 healthy volunteers were randomized to peribulbar (n = 2) or retrobulbar (n = 2) injection of gadolinium and lidocaine hydrochloride, 2%, without epinephrine. Magnetic reson...

THE vast majority of ophthalmic surgeries are performed under regional anesthesia only. However, its use is also described in association with general anesthesia for pediatric cases and for postoperative analgesia. Eye blocks have long been limited to retrobulbar anesthesia (RBA) as performed by surgeons. Surgical technique changes and research on improving patient safety during eye blocks has ...

peribulbar anesthesia is widely applied in cataract surgeries. the aim of this study was comparing the effect of using atracourium, cis-atracourium, and placebo as adjuvant agents to the local anesthetic substance on peribulbar-induced akinesia in cataract surgeries. the study was double-blind randomized clinical trial, among the patients candidate for the cataract surgery who were hospitalized...

Peribulbar block is commonly used for ocular posterior segment surgery. This work aimed to compare the efficacy of using 12.5 mm to 25 mm standard needle length in performing single injection peribulbar block for retinal surgery. Peribulbar block was performed in 120 patients using either standard 25 mm or 12.5 mm 30 G needle (insulin needle). While applying digital pressure around the needle h...

The purpose of this study was to evaluate peri-operative outcome after vitreoretinal surgery when peribulbar anaesthesia is combined with general anaesthesia. Sixty adult patients undergoing elective primary retinal detachment surgery with scleral buckling or an encircling procedure received either peribulbar anaesthesia in conjunction with general anaesthesia or general anaesthesia alone. For ...
