INTRODUCTION This study aims to describe the preferences of ophthalmic anaesthesia for cataract extraction among ophthalmologists in Singapore. METHODS A nationwide questionnaire survey of all cataract surgeons in institutional and private practice in Singapore was conducted in August 2004. RESULTS The response rate was 61.1 percent (88 out of 144 eligible ophthalmologists surveyed). Phacoe...

Twelve thousand regional anaesthetics for cataract extraction and intraocular lens implantation surgery were administered by one anaesthetist over a period of 52 months in a free-standing outpatient surgical facility. The ophthalmologist, who did all the operations, assessed the quality of the blocks using an objective scoring system which is described. The first 3,595 patients had retrobulbar ...

Aims—To determine the relation between pH of anaesthetic solutions and patient perception of pain with peribulbar injection of local anaesthesia. Methods—This prospective randomised controlled double blind pilot study involved 60 consecutive patients who received a peribulbar block with either a standard acidic local anaesthetic of 5 ml 2% lignocaine and 5 ml of 0.5% bupivacaine (solution A), o...

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...
