AVALIACAO DA MOTILIDADE EXTRINSECA OCULAR DE PACIENTES FACECTOMIZADOS SOB ANESTESIA RETROBULBAR

Abstract

Persistent binocular diplopia was related as a complication of ocular surgery under local anesthesia. The literature shows that the anesthetic used caused toxic effects on extraocular musculature. A prospective evaluation of pre and postoperative ocular motility of cataract patients operated under retrobulbar anesthesia with 0.75% bupivacaine hydrochloride was accomplished. The study showed that 7 patients complaining of persistent binocular diplopia presented a similar behavior pattern on the muscle function during the postoperative period. The inferior rectus muscle showed weakness until the first week totally recovering its function between the sixth and ninth week; contrarywise, the superior rectus muscle showed a discrete weakness until the first week, that intensified between the sixth and ninth week.
