Case report: We report a rare complication of retrobulbar anesthesia in ophthalmic surgery- amarurosis and extraocular muscle palsies in the contralateral eye. Our patient did not suffer permanent sequelae from the injection. Discussion: Numerous complications resulting from retrobulbar injections in the eye and orbit have been reported. One possible explanation of this case is the inadvertent penetration of the subdural or subarachnoid space surrounding the optic nerve and the injection of anesthetic into that space. The drug then tracks along the ipsilateral optic nerve to the chiasm and then to the contralateral optic nerve. Several methods of decreasing the probability of such a complication are discussed.

Palabras clave : Retrobulbar block; contralateral II and III nerve palsies; subarachnoid injection.
