BACKGROUND: @entity231 is a major cause of @entity1939 worldwide. Unless medically contraindicated, @entity231 surgery is usually performed under local (regional) anaesthesia. Local anaesthesia involves the blockage of a nerve subserving a given part of the body. It involves infiltration of the area around the nerve with local anaesthetic. The two main approaches in the eye are retrobulbar and peribulbar. There is debate over whether the peribulbar approach provides more effective, safer anaesthesia for @entity231 surgery than retrobulbar block. OBJECTIVES: The objective of this review was to assess the effects of peribulbar anaesthesia (PB) compared to @entity1781 ( @entity1781 ) on @entity158 scores, ocular @entity910 , @entity1 acceptability and @entity149 . SEARCH METHODS: In the previous version of our review, we searched the databases until December 2007. In this updated version, we searched the Cochrane Central Register of Controlled Trials (CENTRAL) (March 2015); MEDLINE (1960 to March 2015); and EMBASE (1980 to March 2015). SELECTION CRITERIA: We included randomized controlled clinical trials comparing peribulbar anaesthesia and @entity1781 for @entity231 surgery. DATA COLLECTION AND ANALYSIS: Two authors independently assessed trial quality and extracted data. We contacted trial authors for additional information, study methodology and missing data. We carried out a descriptive narrative of results as the included studies used varied methods for reporting the outcomes. We performed a subgroup analysis for globe @entity910 . MAIN RESULTS: We included six trials involving 1438 @entity1 . Three of the six trials had adequate sequence generation while all the trials had unclear allocation concealment There was no evidence of any difference in @entity158 perception during surgery with either retrobulbar or peribulbar anaesthesia. Both were largely effective. There was no evidence of any difference in complete @entity910 or the need for further injections of local anaesthetic. @entity3169 was more common after peribulbar block (relative risk (RR) 2.11, 95% confidence interval (CI) 1.46 to 3.05) and lid haematoma was more common after retrobulbar block (RR 0.36, 95% CI 0.15 to 0.88). Retrobulbar @entity548 was uncommon and occurred only once, in a @entity1 who had a retrobulbar block. AUTHORS' CONCLUSIONS: There is little to choose between peribulbar and retrobulbar block in terms of anaesthesia and @entity910 during surgery measuring acceptability to @entity1 , need for additional injections and development of severe complications. Severe @entity149 were rare for both types of block.

Peribulbar versus @entity1781 for XXXX surgery.
