Transient impaired vision,external ophthalmoplegia,and internal ophthalmoplegia after blepharoplasty under local anesthesia

PURPOSE: To report a case of transient bilateral vision impairment with external ophthalmoplegia and internal ophthalmoplegia after blepharoplasty under local anesthesia. DESIGN: Interventional case report. METHODS: A 70-year-old man underwent bilateral upper blepharoplasty under local anesthesia. During orbital fat removal additional anesthetic was injected into both medial fat pads for pain control. RESULTS: Immediate postoperative examination revealed bilateral decreased visual acuity and internal ophthalmoplegia in the right eye. An exotropia was present with marked limitation of right eye adduction. These findings resolved completely 3 hours postoperatively. CONCLUSIONS: Local anesthesia during blepharoplasty can enervate the optic nerve, ciliary ganglion, and extraocular muscle nerves. Local anesthesia should be injected judiciously during orbital fat removal to avoid this reversible but alarming event.
