ABSTRACT

O objetivo é relatar, pela primeira vez, o caso de um paciente submetido à vitrectomia posterior e sutura de perfurante ocular que evoluiu com extravasamento de perfluoroctano para cavidade orbitária. Paciente do sexo masculino, 39 anos, hígido, encaminhado para avaliação oftalmológica após ter sofrido trauma no olho direito com pedaço de metal há um dia. Ao exame, apresentava redução súbita da acuidade visual à direita com ferimento perfurante ocular córneo-escleral, corpo estranho intraocular e descolamento de retina. O paciente foi submetido à sutura de perfurante, introflexão escleral e vitrectomia posterior com utilização de perfluoroctano, quando foi constatada transfixação do globo ocular. No pós-operatório, evoluiu com proptose e presença de imagens hiperdensas à tomografia computadorizada de órbitas, sugerindo tratar-se de extravasamento de perfluoroctano para a cavidade orbitária. Dessa forma, diante de ferimento perfurante ocular, deve--se sempre atentar para a possibilidade de existência de corpo estranho intraocular, bem como para possível ocorrência de transfixação do globo ocular, no momento de se realizar a programação cirúrgica destes casos.


A case of a perfluoro-n-octane leakage into the orbital cavity after corneoscleral suture, scleral buckling and pars plana vitrectomy in an eye with perforating injury after trauma is reported for the first time. A previously healthy 39-year-old man was sent for ophthalmic evaluation one day after suffering a penetrating ocular trauma in his right eye while hammering a nail. On the initial evaluation, the patient presented sudden reduction of visual acuity on his right eye with a perforating corneoscleral injury, intraocular foreign body and retinal detachment. The patient was submitted to corneoscleral suture, pars plana vitrectomy with perfluoro-n-octane administration to flatten the retina and scleral buckling, when it was found transfixation of the globe by the intraocular foreign body. Postoperatively, computed tomography scans of the orbit were ordered due to proptosis, which showed the presence of hyperdense images, suggesting leakage of perfluoro-n-octane into the orbital cavity. Thus, in cases of perforating eye injury, one should be suspicious about the possibility of intraocular foreign body, as well as possible occurrence of transfixation of the globe when scheduling the surgery.
