ABSTRACT
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.

Caso Clínico: Presentamos una rara complicación de la inyección retrobulbar en la cirugía oftalmológica, como es la ceguera y la parálisis de los músculos extraoculares en el ojo contralateral.Nuestro paciente no sufrió secuelas permanentes.Discusión: Se han descrito numerosas complicaciones de la anestesia retrobulbar en el ojo y la órbita. La inyección del agente anestésico en el espacio subdural o subaracnoideo a través de la vaina del nervio óptico (NO) se postula como posible explicación del cuadro. La droga puede alcanzar el quiasma óptico y desde ahí acceder al NO contralateral. Se discuten varios métodos para disminuir la probabilidad de tal afección

CASE REPORT: We present two cases of sialidosis type 1 in two brothers, 28 and 30 years of age. Both have seizures and severe gait instability. Ophthalmoscopic examination showed a cherry-red spot in both eyes. Fibroblast culture revealed a marked reduction in neuraminidase with no alteration in galactosidase, confirming that our patients have sialidosis type I. CONCLUSIONS: We highlight the ease with which this rare syndrome can remain undetected and how a simple ophthalmoscopic examination is able to reveal the diagnosis.
