[Comparison of ophthalmic periconal blockade with 1% and 0.75% ropivacaine with lateral infraorbital and medial canthus punctures.].

Background And Objectives: Several drugs and methods are used for peribulbar blockade. Our objective was to investigate the quality of ophthalmic periconal blockade by the double puncture technique, with different ropivacaine concentrations and without hyaluronidase.

Methods: Participated in this study fifty patients submitted to ophthalmologic surgery, who were randomly allocated in two groups: R1 (1% Ropivacaine) and R0.
