Onehundred and thirty-nine consecutive cases of retrobulbar blocks wer
e evaluated concerning clinical effect on motility and pain. The patie
nts were randomly selected to one of four different mixtures of anaest
hetics. A mixture containing lidocaine w/adrenaline, bupivacaine w/adr
enaline and hyaluronidase was shown to be significantly more effective
than any of the other tested mixtures concerning analgesia and signif
icantly better than mixtures without hyaluronidase concerning motility
/akinesia.
