Resumo: | Our aim is to describe a rare case of complete optic nerve avulsion in a pediatric patient following orbital blunt trauma and its follow-up with multimodal retinal imaging. An 8-year-old boy was admitted after sustaining blunt injury to his right orbital region with a door knob. Upon admission, he had periorbital hematoma, anisocoria, impaired eye movement and absence of light perception in the right eye. Fundus exam revealed sub-hyaloid and peripapillary haemorrhages with an absent optic disc, with a papillary “lacuna” in its place. Computed tomography imaging revealed several orbital fractures with entrapment and stretching of medial and inferior rectus muscles. The patient was managed conservatively and later submitted to reconstructive orbital surgery. There was no improvement in visual acuity six weeks after the trauma. Optic nerve avulsion is a rare complication of orbital trauma that leads to irreversible loss of visual function. In some cases, the diagnosis can be difficult initially due to media opacities. |

Um rapaz de 8 anos de idade foi admitido no serviço de urgência após traumatismo contuso na região orbitária direita com a maçaneta de uma porta. À admissão, apresentava um hematoma periorbitário, anisocoria, restrição nos movimentos oculares e ausência de perceção luminosa no olho direito. A fundoscopia revelou uma hemorragia sub-hialoideia macular e hemorragias peripapilares com a ausência do disco ótico, com uma “lacuna” papilar. A tomografia computorizada orbitária revelou diversas fraturas orbitárias com aprisionamento e estiramento dos músculos retos medial e inferior. O doente foi tratado de forma conservadora e mais tarde foi submetido a cirurgia maxilo-facial. Não houve recuperação da acuidade visual durante o follow-up. A avulsão do nervo ótico é uma complicação rara de traumatismos orbitários que leva a perda irreversível da função visual. Em alguns casos, o diagnóstico pode ser dificultado inicialmente por opacidades dos meios óticos.Ajnet2023-12-29info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/reporthttps://doi.org/10.48560/rspo.31469eng1646-69501646-6950Miranda, VítorPestana Aguiar, CatarinaAlves Ambrósio, JoãoChibante Pedro, JoãoRuão, MiguelCosta, Joãoinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-01-04T20:30:33Zoai:ojs.revistas.rcaap.pt:article/31469Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T01:30:08.264952Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
