ABSTRACT
Objetivo: relatar um caso de ferimento por arma de fogo (FAF), com projétil balístico alojado em região infraorbitária à esquerda, relatando tratamento cirúrgico de urgência para exérese do projetil por acesso subciliar. Relato do caso: Paciente do gênero masculino, 18 anos, foi encaminhado ao pronto socorro do Hospital Universitário por conta de ferimento por arma de fogo. Ao exame clínico, foi verificado discreto aumento de volume em região cervical e hemiface à esquerda, ausência de sangramento em face; presença de limitação para infraversão de olho esquerdo. O orifício de entrada do projetil foi identificado em região de tórax superior posterior à esquerda; após realização de tomografia de face, confirmou-se fratura de assoalho orbitário esquerdo, assim como projétil alojado abaixo do globo ocular. O ato cirúrgico foi realizado com caráter de urgência pela equipe de Cirurgia e Traumatologia Bucomaxilofacial. Discussão: estudos descrevem a importância da realização do adequado manejo de lesões traumáticas decorrentes de FAF seguido de remoção do projetil com urgência, visto que as complicações ao postergar o tempo cirúrgico só agravam o quadro clínico do paciente, além das afecções futuras que podem surgir com o decorrer da resolução do caso clínico. Conclusão: ratifica-se a importância da multidisciplinariedade entres as clínicas médicas, assim como, o correto manejo do paciente traumatizado, baseado nos critérios que conduzem o plano de tratamento.(AU)
Aim: to report a case of gunshot wound, with ballistic projectile lodged in the left infraorbital region, reporting emergency surgical treatment for projectile exeresis by subciliary access. Case Report: An 18-year-old male patient was referred to the emergency department of the University Hospital due to a gunshot wound. On clinical examination, it was found slight increase in volume in the cervical region and left hemiface, absence of bleeding in the face; presence of limitation to infraversion of the left eye. The entrance hole of the projectile was identified in the posterior left upper thorax region; after a tomography of the face, a fracture of the left orbital floor was confirmed, as well as the projectile lodged below the eyeball. The surgery was urgently performed by the Oral and Maxillofacial Surgery team. Discussion: Studies describe the importance of performing the proper management of traumatic injuries resulting from FAF followed by removal of the projectile with urgency, since the complications to postpone the surgical time only aggravate the clinical picture of the patient, in addition to future problems that may arise with the resolution of the clinical case. Conclusion: the importance of multidisciplinarity among medical clinics is ratified, as well as the correct management of the traumatized patient, based on the criteria that lead to the treatment plan.(AU)

Introdução: Trauma contuso e penetrante na região orbital pode ter um efeito devastador, tanto funcional quanto estético para a órbita e estruturas adjacentes. Uma inspeção meticulosa das pálpebras e do globo deve ser realizada e, se houver suspeita de retenção de um corpo estranho dentro dos tecidos moles orbitais, deve ser obtida uma tomografia computadorizada (TC). O objetivo do presente estudo foi relatar um caso clínico de trauma óculo-orbitário severo ocasionado por acidente com animal. Relato de caso: paciente de 22 anos do gênero masculino apresentou-se em um hospital de referência em trauma na cidade de Campina Grande-PB, com história de acidente com cavalo e colisão em cerca de madeira. A tomografia revelou que havia a presença de um corpo estranho (CE) de madeira que apresentava uma forma pontiaguda e proximidade com estruturas como músculos, vasos e nervos da órbita, além da presença de fratura no assoalho da órbita. Considerações finais: A presença de CE de madeira deve sempre ser investigada quando há trauma direto na cavidade orbitária, pois a madeira é áspera e contém uma grande quantidade de bactérias e parasitas. Sendo assim, deve ser removido o mais precocemente possível a fim de se evitar complicações infecciosas... (AU)
Introduction: Blunt and penetrating trauma to the orbital region can have a devastating effect, both functional and aesthetic for the orbit and adjacent structures. Meticulous inspection of the eyelids and the globe should be performed and, if a foreign body is suspected to be retained within the orbital soft tissues, a computed tomography (CT) scan should be obtained. The aim of the present study was to report a clinical case of severe oculo-orbital trauma caused by an accident with an animal. Case report: a 22-year-old male patient presented at a trauma referral hospital in the city of Campina Grande-PB, with a history of accident with a horse and collision on a wooden fence. The tomography revealed that there was the presence of a wooden foreign body (EC) that had a pointed shape and proximity to structures such as muscles, vessels and nerves in the orbit, in addition to the presence of a fracture in the orbit floor. Final considerations: The presence of wood CE should always be investigated when there is direct trauma to the orbital cavity, as the wood is rough and contains a large amount of bacteria and parasites. Therefore, it should be removed as early as possible in order to avoid infectious complications... (AU)

BACKGROUND: Determining the precise location of intraocular foreign bodies is crucial for the management of patients with open-globe injury. Computed tomography is the most common method for detecting intraocular foreign bodies in the posterior segment. In this article, we describe three cases of open-globe injury with different types of intraocular foreign bodies in the posterior segment that were accurately located using computed tomography scans and B-scan ultrasonography. CASE PRESENTATION: Each of the three cases of open-globe injury described in this report had different types of ocular trauma, clinical symptoms, and intraocular foreign bodies. Computed tomography scans showed the exact location of the intraocular foreign bodies in the posterior segment in two of the three cases. A B-scan ultrasound was used to determine the location of a non-metallic intraocular foreign body in the third case. All three patients had intraocular foreign bodies, and one of them had an additional orbital foreign body. Case 1 had a perforating eye injury with the additional intraorbital foreign body; Cases 2 and Case 3 had different types of intraocular foreign bodies and prognoses. Various treatment approaches were used, ranging from observation to surgery, depending on the location of the intraocular foreign bodies, and all cases were successfully managed. These three cases show that proper use of various types of imaging tests is indispensable in the context of an intraocular foreign body related to open-globe injury. CONCLUSION: Imaging techniques are crucial for the detection of an intraocular foreign body, and computed tomography is one of the simplest and most useful, especially in cases of open-globe injury.
ANTECEDENTES: La ubicación precisa de un cuerpo extraño intraocular es crucial para el manejo de pacientes con trauma ocular abierto. La tomografía computarizada se usa habitualmente para detectar su ubicación en el segmento posterior. Reportamos tres casos con diferentes cuerpos extraños intraoculares en el segmento posterior, que fueron localizados con precisión mediante la tomografía computarizada y ecografía modo B. PRESENTACIÓN DEL CASO: Presentamos tres casos con diferentes mecanismos de trauma, tipos de cuerpo extraño intraocular, síntomas clínicos y pronóstico visual. La tomografía computarizada determinó la ubicación exacta de todos los cuerpos extraños intraoculares en el segmento posterior. El ultrasonido modo B se realizó en un paciente con un cuerpo extraño intraocular no metálico. El primer caso tuvo una lesión ocular perforante con un cuerpo extraño intraorbitario; el caso dos y el caso tres presentaron diferentes tipos de cuerpos extraños intraoculares con pronóstico diferente. El manejo y el pronóstico fue distinto en todos los casos; todos se manejaron con éxito. La ubicación exacta de los cuerpos extraños intraoculares utilizando las diferentes modalidades de diagnóstico es importante en estos pacientes. Estos casos sirven como recordatorio de que el uso adecuado de las pruebas de imagen es indispensable en el contexto de un cuerpo extraño intraocular relacionado con trauma ocular abierto. CONCLUSIÓN: Las diferentes técnicas de imágenes son muy importantes para la detección de un cuerpo extraño intraocular. La tomografía computarizada es una de las modalidades de imagen más simple y efectiva para la localización de cuerpos extraños intraoculares relacionadas con trauma ocular abierto.

PURPOSE: The aim is to report a case of conjunctival tattooing with inadvertent injection of tattoo ink into the vitreous cavity and its consequences, the scanning electron microscopy X-ray microanalysis of the ink components, and the microscopic findings of the affected conjunctiva and vitreous. METHODS: Descriptive case report. RESULTS: A 32-year-old man complained of ocular pain and blurred vision after undergoing a subconjuctival red ink tattoo in his left eye. Ophthalmologic examination revealed best corrected visual acuity of 20/80 and intraocular pressure of 26 mmHg. Pain was elicited with eye movements. The bulbar conjunctiva was colored intense red. In the anterior chamber, pigment granules and filaments were suspended on the aqueous humor, and lens capsule was also stained red. Ultrasonography showed high-density non-mobile echoes in the conjunctiva; anterior chamber and vitreous cavity revealed high-density mobile echoes corresponding to pigment particles. Conjunctival tattoo with inadvertent globe penetration was the clinical diagnosis. The patient received medical and surgical treatment. Histopathological examination of the conjunctiva showed red pigment globular deposits within the stroma, and neutrophils and sparse histiocytes with similar intracytoplasmic pigment granules were seen. No granulomatous foreign body reaction was noticed. Vitreous material contained pigment granules; no inflammatory cells were observed. Scanning electron microscopy X-ray microanalysis of the tattoo red ink revealed significant signals of iron, barium, and copper. CONCLUSION: Conjunctival tattoo is a new form of body decoration gaining worldwide popularity. This procedure is performed by untrained professionals causing severe ocular complications including blindness. Safety regarding tattoo ink needs further study as the composition varies among colors. Strict regulations on this matter should be considered.

PURPOSE: To investigate the reliability of ultrasound in determining the size and identify the sonographic features and artifacts generated by intraocular foreign bodies of different materials. METHODS: Experimental study using 36 enucleated porcine eyes. Fragments of nine different compositions (wood, glass, plastic, cardboard, iron, aluminum, lead, powder and concrete) and similar dimensions (4 mm) were implanted via scleral incision into the vitreous cavity of 36 porcine eyes, four eyes were used for each material. Ultrasound examination was performed in all eyes using the contact technique, conductive gel and 10-MHz transducer (EZScan, Sonomed). RESULTS: Considering the material fragments of gunpowder, lead, concrete, aluminum, wood and glass, the size determined by ultrasound was considered statistically similar to the actual size. The material iron presented ultrasound-determined dimension statistically smaller than its actual size. Cardboard and plastic materials showed ultrasound-determined measurements far greater than the actual. All fragments of intraocular foreign bodies demonstrated hyper-reflective interfaces, irrespective of their composition. Whereas the artifacts generated by different materials, it was found that the materials iron, aluminum and lead showed reverberation of great extent. The material wood showed no reverberation. The length of the reverberation artifact for the materials iron, glass, aluminum and cardboard was lower when compared to other materials. All materials presented posterior shadowing artifact, with the exception of aluminum. CONCLUSION: Ultrasonography was considered a reliable technique to determine the size of intraocular foreign bodies in pigs, with little influence caused by its composition. Ultrasound artifacts generated were considered material-dependent and can assist the examiner to identify the nature of a foreign body of unknown etiology. Ultrasonography aided the surgeon to identify, locate and measure the intraocular foreign body, directing appropriate surgical planning.

We report a case of unsuspected penetrating trauma with intraorbital foreign body, namely a needlefish jaw. A 44-year-old fisherman presented with vertical diplopia and discrete swelling of the upper lid near the medial canthus after being hit by a fish. He was unaware of any penetrating lesion or foreign body. There was no entry wound. CT-scan showed a foreign body between the globe and the medial orbital wall. Surgical exploration found that it was a 4.5cm long needlefish jaw. Removal resulted in complete resolution of symptoms. Needlefish can be very dangerous. This is the first reported case of a needlefish jaw in the orbit with no associated lesion, infection or inflammation.

INTRODUCTION: Ocular trauma is considered a health care problem because is an important cause for visual impairment. Intraocular foreign bodies are related to activities involving usage of metallic objects, but other materials can be present in the eye and have to be diagnosed and localized. Ultrasound biomicroscopy is an adequate subsidiary tool to evaluate an anterior chamber intraocular foreign body. PURPOSE: To characterize nature, localization, dimensions of foreign bodies and associated lesions to the anterior segment using ultrasound biomicroscopy. METHODS: Retrospective clinical study of 7,182 patient's charts submitted to ultrasound biomicroscopy examination between 1999 and 2008, totalizing 59 eyes suspected of anterior segment foreign body. RESULTS: Five cases presented two foreign bodies, fragments from the same nature, in different locations or not; and three cases had uncountable fragments in the anterior segment. Concerning localization: cornea, 11 (26%); conjunctiva, 10 (23%); iris, 10 (23%); lens, 9 (21%); sclera, 5 (12%); corneal angle, 5 (12%); ciliary body, 3 (7%). Among the associated lesions, it was identified: corneal perforation in 12 cases, corneal laceration in 2 cases, anterior synechia in 6 cases, traumatic aniridia 1 case, traumatic iridotomy in 3 cases, anterior chamber reaction in 10 cases and rupture of the anterior lens capsule in 4 cases. Considering composition: metallic, 21 (50%); non metallic, 20 were glass (48%) and 1 was vegetal (2%). The size of foreign bodies varied from 0.09 to 2.45 mm (average: 0.84 mm). CONCLUSIONS: Ultrasound biomicroscopy is useful to localize foreign bodies in the anterior segment. This imaging method can give orientation about composition, path, and localization of foreign bodies and associated lesions, thus facilitating therapeutic planning prior to intervention, avoiding additional lesions to the eye.

Orbital injuries may be associated with the presence of foreign bodies in which long retention leads to damages such as loss of vision or cerebral abscess. We present the case of a 21-year-old male patient that developed ptosis, limitation of movements and an inflammatory reaction in the right eye after being hit by a tree branch. A CT scan of the orbits revealed an increased density in the right orbital cone. After the neurosurgical approach for the removal of the foreign body, a wooden fragment measuring 2.0x0.3 cm, the patient had a good outcome without visual deficits, ptosis regression and resolution of the inflammatory process. The postoperative CT scan didn't identify any remaining foreign body fragment. This case calls attention to the fact that the wooden splinter presented on CT scan with high density (136 HU) two months after the trauma and was removed by a supraorbital craniotomy.

Blunt or perforating trauma can cause considerable damage to both the anterior and posterior segment of the eye. Since the media are often opaque following trauma, the extent of the damage may be difficult to assess with routine examination. Ultrasonography can reveal hidden pathology and is often helpful in deciding upon the proper line of treatmemt. In post-contusional trauma without an open globe, full ultrasonographic investigation, including immersion techniques, can be performed. On the contrary, after perforation lesions, an exploratory B-scan can be used for locating an intraocular foreign body in addition to gross assessment of the damage. The ultrasonographic examination can only be continued in further detail after primary closure of the wound. When an x-ray of the orbit reveals the presence of an intraocular foreign body B-mode ultrasonography is superior to the Comberg-Pfeiffer method and computer tomography for precise localizations of the object and for detection of collateral damage. Transpalpebral echography or scans with the probe directly applied to the eye, at significantly reduced sensitivity levels (-20 or -30 dB) are the methods of choice for tracing a foreign body in the posterior segment or orbit. Lowering the sensitivity settings will also improve the accurate location of the foreign body. The immersion technique is used when the foreign body is located anteriorly in the eye, providing that the entry wound is closed. In particular after contusional injuries, ultrasound biomicroscopy (UBM) can be used for detailed observations of the cornea, anterior lens, chamber angle and ciliary body. Recession of the angle, subluxation of the lens and dialysis of the iris or ciliary body can be diagnosed with relative ease. When vitrectomy is indicated either as a primary or secondary procedure following ocular trauma, ultrasonography is essential in the preoperative evaluation. It will help in deciding upon the length of the preoperative period, the estimated duration of the operation and the appropriate surgical approach. A full anatomical analysis can be obtained by systemically assessing the biometric, topographic, kinetic and quantitative characteristics of the various parts of the eyes. The most commonly occuring ocular pathology following trauma, along with the most suitable diagnostic ultrasonic techniques will be discussed in detail and are depicted in the table. (AU)
