@entity6839 of 0.5% was applied in 6 eyes prior to @entity231 extraction, while 7 eyes were not treated. @entity7462 was drawn after retrobulbar analgesia with 2% @entity3303 and analyzed for @entity1425 and @entity1063 using a radioenzymatic assay. @entity1425 levels averaged 15.8 +/- 16.2 and 19.3 +/- 27.5 pg/ml in the @entity6839 treated group and controls respectively. The corresponding values for @entity1063 were 1.59 +/- 0.55 and 1.87 +/- 0.90 ng/ml. These differences were not statistically significant. @entity1063 levels in this study were somewhat higher than in previous reports of @entity2922 levels in @entity1 @entity7462 and considerably higher than plasma levels of @entity1063 . There was no significant correlation between @entity7462 @entity1063 levels and age in the two groups combined. The mean @entity1063 levels for @entity1 and @entity1 in the two groups combined were 1.73 +/- 0.89 and 1.76 +/- 0.56 ng/ml. The difference was not statistically significant. @entity6839 resulted in a decrease in the intraocular pressure.

@entity1 XXXX catecholamines.
