Síndrome de Pierre Robin associada à Síndrome de Duane familiar do tipo III / Pierre Robin Syndrome associated with type III familial Duane Retraction Syndrome

Resumo A síndrome de Pierre Robin (PRS) consiste em uma tríade de anomalias caracterizada por micrognatia, glossoptose e fissura de palato, comumente associada com outras síndromes e ocasionalmente com alterações oculares. Na Síndrome de Duane (DRS), há uma falha na inervação do reto lateral pelo VI nervo, com inervação anômala do reto lateral por fibras do III nervo. Ainda que a PRS já tenha sido associada com mais de 50 outras síndromes, não existe na literatura relato de casos de associação com a DRS familiar. Dessa forma, esse trabalho tem por objetivo relatar um caso dessa associação em um paciente de 29 anos com recorrência das síndromes na família.

Abstract The Pierre Robin Syndrome (PRS) consists of a triad of anomalies characterized by micrognathia, glossoptosis and fissure of the palate, usually associated with other syndromes e occasionally associated with ocular variations. In Duane Retraction Syndrome (DRS), there is a failure in the lateral rectus innervation by the VI cranial nerve, with anomalous innervation of the lateral rectus by fibers of the III nerve. Even though PRS has already been associated with more than 50 other syndromes, there is not any report in literature of association with familial DRS. Thus, this work aims to report a case of this association in a 29 years old patient with recurrence of the syndromes in the family.

Normal Abduction in a Patient with Duplicated Abducens Nerve

PURPOSE: To our knowledge, there has been no report of ophthalmologic findings related with a duplicated abducens nerve in the ophthalmic literature. This study reports such findings. METHODS: An ophthalmologic examination was performed in one patient with a duplicated abducens nerve, revealed with thin-sectioned magnetic resonance imaging (MRI) across the brainstem level. RESULTS: The MRI disclosed a duplicated left abducens nerve. The patient was orthotropic in five cardinal positions, and her ductions and versions were full. CONCLUSIONS: One patient with a duplicated abducens nerve showed orthotropia and normal ocular movement.
