Diplopia from peribulbar ropivicaine
Purpose:
To report a previously undescribed side-effect of ropivicaine (Naropin) used in peribulbar anaesthesia.
Methods:
We report nine cases identified prospectively with symptomatic diplopia, predominantly vertical, following Ropivicaine use for peribulbar anaesthesia in routine cataract surgery. These nine cases occurred in a 10-week period from a total of 77 patients given 7 mL peribulbar ropivicaine (10 mg/mL) with 750 units hyalase prior to cataract extraction by a single surgical team.
Results:
None of the cases had preoperative ocular motility disturbances and none had superior rectus traction sutures. All diplopia resolved in less than 30 h.
Conclusions:
Ropivicaine may have a prolonged motor block resulting in diplopia of up to 30 h duration after peribulbar anaesthesia.
