As increasing numbers of anesthetists perform eye block anesthesia, thorough understandings of peribulbar injection techniques are important for safe practice. There is uncertainty in the literature regarding the optimum needle length, entry point, volume of injectate, and use of single vs double-injection techniques. A modified technique of peribulbar block anesthesia is presented, which offer...

Ofra S/N La Cuesta, 38320 La Laguna, Tenerife, Canary Islands, Spain Email [email protected] Dear editor We read with interest the recently published article “Superior subconjunctival anesthesia versus retrobulbar anesthesia for manual small-incision cataract surgery in a residency train...

Objectives: Vitreous and retinal (VR) surgery with or without scleral buckling is associated with significant postoperative pain in adults, and recent studies have addressed the effect of retro or peribulbar block on these parameters. VR surgery in children has received little attention regarding the incidence of pain and the role of regional anesthesia in modifying these parameters. In this st...

BACKGROUND Peribulbar and retrobulbar anesthesia have long been opposed on the basis of the existence of an intermuscular membrane, which is supposed to separate the intraconal from the extraconal spaces in a water-tight fashion. A local anesthetic injected outside the cone should spread through this septum to reach the nerves to be blocked. The existence of this septum is questioned. The aim o...

BACKGROUND We evaluated the anesthetic efficacy and the postoperative analgesic effects of 0.75% levobupivacaine versus 0.75% ropivacaine for peribulbar anesthesia in patients undergoing primary vitreoretinal surgery. METHODS We investigated 120 patients subjected to vitreoretinal surgery under peribulbar anesthesia. They were randomized into two equal groups according to the local anesthetic...

purpose: to compare low volume transconjunctival anterior peribulbar anesthesia with transcutaneous posterior peribulbar anesthesia in phacoemulsification. methods: patients scheduled for phacoemulsification were randomly divided into two groups: in first group 5ml of 2% lidocaine was injected transcutaneously in the posterior orbital space. in the second group, 2ml of 5% lidocaine was injected...

PURPOSE To assess the risk for and circumstances of serious complications during peribulbar and retrobulbar anesthesia. SETTING University eye departments, Freiburg and Würzburg, Germany, and Skopje, Macedonia. METHODS This retrospective analysis comprised patients who received secondary care for complications of inadvertent globe perforation during peribulbar or retrobulbar injections over...

BACKGROUND Retro- or peribulbar anesthesia are the standard procedures for cyclodestructive surgery. Because these methods of anesthesia may further compromise optic nerve function, especially in advanced glaucoma, subconjunctival anesthesia was evaluated as an alternative procedure in contact diode laser cyclophotocoagulation (CPC). PATIENTS AND METHODS A prospective study concerning diode l...

OBJECTIVE To compare the efficacy of subtenon with peribulbar local anesthesia without hyaluronidase in patients undergoing cataract surgery. STUDY DESIGN A randomized controlled trial. PLACE AND DURATION OF STUDY Eye "B" Unit, Khyber Teaching Hospital, Peshawar, from October 2009 to October 2010. METHODOLOGY Patients undergoing cataract surgery were divided into two groups. Group A recei...

CLINIC CASE Peribulbar anesthesia is used in daily practice during cataract surgery. It is a safe technique, but not without complications. We present the case of a man who had an orbital abscess secondary to peribulbar anesthesia that led to the perforation of an unknown frontoethmoidal mucocele. DISCUSSION Orbital abscess secondary to an iatrogenic mucocele perforation after anesthesia is a...
