BACKGROUND: Transient @entity2194 as a complication of parabulbar and peribulbar anesthesia has already been reported in the literature. The aim of our study was to present a case of irreversible iatrogenic vertical strabismus after @entity231 surgery, which had to be operated on. METHODS: Clinical and orthoptic evaluation of a female @entity1 with @entity892 after phacoemulsification @entity231 surgery. RESULTS: One week after the uneventful surgery, a 68-year-old @entity1 complained of a sudden vertical deviation in the operated eye. The @entity1 had not had a history of previous @entity1319 . On examination, the @entity1 showed @entity15170 in the left eye of 15-20 degrees in primary position. Three and 6 months postoperatively, there was no a spontaneous improvement, while the persistent vertical deviation was 40 prism dioptres. Strabismus surgery was required 1 year after the @entity231 surgery. CONCLUSION: @entity892 is a complication of peribulbar anesthesia which could be persistent. The superior and inferior rectus muscle are especially vulnerable. Its occurrence may be technique--related and the incidence increases when hyaluronidase is not available.
