We report a case of bilateral orbital hemorrhage as a complication of peribulbar anesthesia in a 78 year old man. Initially, unilateral orbital hemorrhage occurred but quickly spread to the contralateral side. Neuroophthalmological assessment revealed a proptosed tense globe with normal retinovascular findings. Visual acuity was adversely affected and this was conservatively managed with no las...

PURPOSE This study compared the efficacy of single-injection percutaneous peribulbar anesthesia (PBA) with a short needle with sub-Tenon's anesthesia (STA) to produce optimal operating conditions for cataract extraction in patients with complicated cataract. METHODS Two hundred patients with complicated cataract were enrolled in this prospective, double-blinded, randomized study. Adequate aki...

Background: Owing to the advanced age of patients scheduled for cataract and IOL insertion, and the high concentrations of local anesthetic used in peribulbar blockade, the use of ropivacaine produces an effective motor blockade with minimal risks for neuro and cardiotoxicity.concerning globe injury due to multiple injection the new single injection medial canthus is theoretically preferred to ...

OBJECTIVE To evaluate the results of monocular surgery under peribulbar anesthesia for large-angle horizontal strabismus. INTRODUCTION Monocular surgery may preserve some muscles if a repeat operation is required, may help to avoid the exposure of the dominant eye to the inherent risks of a surgical procedure and may reduce surgical time. METHODS We evaluated ninety-two consecutive patients...

we are convinced that sub-Tenon blocks produce a more consistent (reproducible) anesthesia than do peribulbar injections. This probably is due to anatomic reasons explained in our previous articles. –7 From an anatomic point of view, the difference between both technique groups can be better understood by using an analogy with perimedullary blocks: peribulbar injection can be assimilated to epi...

BACKGROUND AND OBJECTIVES Currently there is no agreement regarding which one is the most adequate anesthetic technique for the treatment of retinopathy of prematurity. Peribulbar block may reduce the incidence of oculocardiac reflex and postoperative apnea. The goal of this study was to report the outcomes of peribulbar block, when combined with general anesthesia, for the laser treatment for ...

The aim of this study was to compare the effects of ropivacaine with those of lidocaine on the intraocular pressure (IOP) and the quality of the blockade in peribulbar anesthesia for cataract surgery. Fifty patients were allocated randomly into two groups and received 7-10 ml of 0.75% ropivacaine or 2% lidocaine with adrenaline, though the peribulbar two-point injection. The quality of the bloc...

For many years, retrobulbar and peribulbar anesthesia were the standard for cataract surgery; however, many serious adverse effects have been reported (1, 2). With the introduction of modern phacoemulsification cataract surgery, topical anesthesia without retrobulbar or periocular injections has become a well-established, minimally invasive technique (3). The addition of intracameral lidocaine ...
