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...

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...

PURPOSE To determine whether the addition of 0.4% ropivacaine to the standard 2% lidocaine peribulbar anesthetic block improves pain scores during suture adjustment in patients undergoing strabismus surgery with adjustable sutures. METHODS Prospective, double-blind study of 30 adult patients aged 21-84 years scheduled for elective strabismus surgery with adjustable sutures. Patients were divi...

PURPOSE To determine the effects of 6.0% carboxymethylcellulose (CMC) in modifying the oculomotor system of rabbits by means of viscoelastic action forces, the durability of this effect and possible inflammatory reaction. METHODS Twenty-five New Zealand rabbits were divided into two experimental groups: one treated with a peribulbar injection of 6.0% CMC and a control group submitted to perib...

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...

BACKGROUND Vitreoretinal (VR) surgery has been increasingly performed under local anaesthesia (LA) in this unit. The results of an audit monitoring this change are presented. METHODS Data were collected on 1497 patients including type, volume, and position of the anaesthetic block, type of surgery, complications, and patient reactions. RESULTS 1221/1479 (82%) patients had LA. They were olde...
