Video Caso Clínico: Trauma Ocular con Herida Penetrante con Hernia de Iris / Clinical Case video: Ocular Trauma Penetrating Eye Enjury with Iris Proplase

INTRODUCCIÓN: En lo que a traumatismos se refiere, el ojo es el tercer órgano más afectado después de manos y pies [1]. El trauma ocular constituye una de las principales causas de pérdida de la visión unilateral y determina consecuencias graves en el ámbito psico-social del individuo; siendo la causa más común de ceguera unilateral en la edad pediátrica, principalmente en países en vías de desarrollo [2]. La epidemiología de las lesiones oculares depende de varios factores; como el estilo de vida, el estado socioeconómico y las actividades deportivas y recreativas [2]. Según la Organización Mun-dial de la Salud (OMS), la incidencia anual mundial de traumatismo ocular es de alrededor de 55 millones [1]. Alrededor del 38-52% de todos los casos de urgencias oftálmicas son traumas ocu-lares y el 0.9-1.8% de ellos deben ser ingresados debido a un traumatismo grave [2]. Las lesiones varían desde una pequeña abrasión epitelial de la córnea hasta penetración y ruptura del globo [3]. El desgarro de la córnea, el desgarro de la esclerótica y el daño de la lente son las morbilidades observadas con mayor frecuencia del traumatismo ocular, seguidas de laceración del párpado, prolapso uveal, anomalías de la cámara anterior, desprendimiento de retina y avulsión del nervio óptico [1]. Las lesiones oculares, incluso las de menor importancia, pueden generar importantes cargas económicas por la necesidad de cuidados especiales, la costosa hospitalización, tratamiento y rehabilitación visual [2]. Este artículo presenta un caso clínico de trauma ocular, con pronóstico desfavorable según OTS. Epidemiológicamente entre el 30-40% de las cegueras monoculares son producidas por traumas oculares [2]. Al existir un trauma ocular con herida penetrante, se debe intervenir de forma oportuna en las primeras 24 horas para prevenir complicaciones y mejorar el pronóstico [4].(au)

BACKGROUND: The eye is the third most common organ affected by trauma after hands and feet [1]. Eye trauma is one of the main causes of unilateral vision loss and imposes major social and psychological impact on patients; in fact it is the most common cause of unilateral blindness in pediatric age groups, especially in developing countries [2]. The epidemiology of eye injuries depends on several factors, such as lifestyle, socioeconomic sta-tus, and sports and recreational activities.[2] According to the World Health Organization (WHO), the global annual incidence of eye trauma is around 55 million [1]. About 38-52% of all cases in ophthal-mic emergency rooms are ocular traumas and 0.9-1.8% of them needs to be admitted due to severe trauma [2]. Corneal tear, scleral tear and lens damage are the most frequently observed morbidities of ocular trauma, followed by lid laceration, uveal prolapse, anterior chamber abnormality, retinal detachment and optic nerve avulsion. [1]. Eye injuries, even the minor ones, can result in significant economic burdens due to special care and family costs, the expensive hospital admission, treatment and visual rehabilitation. [2] We present a case report of ocular trauma, with poor prognosis according to OTS. Epidemiologically between 30-40% cases of monocular blindness are caused by eye trauma [2]. In cases of ocular trauma with penetrating injuries, patients should be treated in the first 24 hours to prevent complications and improve the prognosis [4].(au)

Ruptura del globo ocular / Rupture of the eyeball

Los traumatismos oculares representan la principal causa de pérdida de la agudeza visual en individuos jóvenes y se sitúa entre las causas de ceguera en el mundo. Pueden tener un efecto devastador sobre el globo ocular; es el tipo de traumatismo más severo en esta zona, con un pobre pronóstico visual para el paciente. Constituye un accidente grave, que en muchas ocasiones conlleva a la enucleación. Se presentan tres pacientes con rotura del globo ocular, con la conducta terapéutica, seguimiento y resultados visuales en cada caso, para mostrar a la comunidad médica, la complejidad y particularidades de este traumatismo(AU)

Ocular traumatisms represent the principal cause of loss of vision in young people and they are among the causes of blindness in the world. Trauma can result in a wide spectrum of tissue lesions of the globe and it can has devastating effect on the eyeball, since it is the most severe type of trauma in this area, with a poor visual prognosis for the patient. It is a serious accident, which often leads to nucleation as result of a bruised intense trauma. This is the report of three patients with rupture of the ocular globe with the therapeutic behavior, follow-up and visual results in each case, to show the medical community, the complexity and particularities of this traumatism(AU)

Ultrasound biomicroscopy confirmation of corneal overriding due to improper suturing of full-thickness corneal laceration / Confirmação por biomicroscopia ultrassônica de encavalamento corneano devido à sutura inadequada de laceração de espessura total da córnea

We herein present a case with corneal overriding due to improper suturing of a full-thickness corneal laceration. There was a 2.5-mm difference between horizontal and vertical white-to-white measurements in the cornea. However, slit lamp examination failed to demonstrate the exact architecture of the laceration. Ultrasound biomicroscopy defined the wound edges thoroughly and confirmed the presence of corneal overriding. Six weeks after suture enhancement, the abnormal oval appearance of the cornea was absent and correct apposition of the corneal edges was seen on ultrasound biomicroscopy. Ultrasound biomicroscopy can be used in preoperative surgical planning of cases with complicated corneal lacerations. It can be used to adjust and enhance wound architecture in eyes with penetrating injury.

Apresentamos um caso com encavalamento corneano devido à sutura inadequada de uma laceração da córnea de espessura total. Houve uma diferença 2,5 mm entre as medidas do branco ao branco horizontais e verticais na córnea. No entanto, o exame da lâmpada de fenda não conseguiu demonstrar a arquitetura exata da laceração. A biomicroscopia ultrassônica definiu as bordas da ferida completamente e confirmou a presença de encavalamento da córnea. Seis semanas após a melhora da sutura, a aparência oval anormal da córnea havia desaparecido, e a correta aposição das bordas da córnea foi identificada na biomicroscopia ultrassônica. A biomicroscopia ultrassônica pode ser usada no planejamento cirúrgico pré-operatório de casos com lacerações corneanas complicadas. Ela pode ser utilizada para ajustar e melhorar a arquitetura da ferida em olhos com lesão penetrante.

Traumatic avulsion of extraocular muscles: case reports / Avulsão traumática de músculos extraoculares: relatos de casos

We described the clinical, surgical details and results (motor and sensory) of the retrieving procedure of traumatically avulsed muscles in three patients with no previous history of strabismus or diplopia seen in the Department of Ophthalmology, State University of Campinas, Brazil. The slipped muscle portion was reinserted at the original insertion and under the remaining stump, which was sutured over the reinserted muscle. For all three cases there was recovery of single binocular vision and stereopsis.

Foram descritos os quadros clínicos, detalhes cirúrgicos e resultados (motores e sensoriais) da reinserção de músculos traumaticamente avulsionados, em três pacientes sem estória prévia de estrabismo ou diplopia, atendidos no Departamento de Oftalmologia da Universidade Estadual de Campinas. A porção muscular deslizada foi reinserida na linha da inserção original e sob o coto remanescente, o qual foi acomodado e suturado sobre o músculo reinserido. Para os três casos houve recuperação da visão binocular única e da estereopsia.

Prognostic factors for vision outcome after surgical repair of open globe injuries.

Purpose: To evaluate the factors influencing final visual outcome after surgical repair of open globe injuries. Materials and Methods: The study was carried out at a tertiary referral eye care center in Central India. In this retrospective study, case records of 669 patients with open globe injuries were analyzed. Different preoperative variables were correlated with the final visual outcome. Exclusion criteria were patients with less than four months follow up, previous ocular surgery, presence of intraocular foreign body or endophthalmitis at the time of presentation. Using statistical tests, the prognostic factors for vision outcome following surgical repair of open globe injuries were studied. Results: Based on the Spearman's Rho correlation analysis, following factors were found to be significantly associated with the final visual acuity at univariate level: age (P<0.001), preoperative visual acuity (P=0.045), mode of injury (P=0.001), and time lag between the injury and surgery (P=0.003). None of the other clinical factors have statistically significant correlation with final visual acuity. On multivariate analysis using binary logistic regression, only age, mode of injury and the time lag between injury and surgery achieved statistically significant results. Conclusion: In the current study, elapsed time between the injury and surgery, age of the patient, preoperative visual acuity and mode of injury were found to be adversely affecting the final visual outcome. Recognizing these factors prior to surgical intervention or intraoperatively can help the surgeon in evidence-based counseling of the trauma victim and family.

Perfluoroctano em cavidade orbitária após vitrectomia posterior e sutura de perfurante ocular: relato de caso / Perfluoro-n-octane in orbital cavity after posterior vitrectomy and suture of eye perforating injury: case report

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.

An unusual case of penetrating ocular trauma with metallic spoon.

Ocular trauma is an important cause of vision loss. The agents incriminated in such injuries are diverse. We present a case of ocular trauma with a metallic spoon causing deep laceration of lid and temple region with sclerocorneal laceration. After assessment of the general condition and stabilization of the systemic parameters the operative procedure was undertaken on elective basis. Though the final visual outcome was not rewarding due to the severity of the injury, any potential hemostatic catastrophe was averted.

Descriptive study on ocular survival, visual outcome and prognostic factors in open globe injuries.

A prospective observational study was done to assess ocular survival, visual outcome and prognostic factors of open globe injury. Eighty eyes of penetrating trauma between 2004 and 2006 were categorized according to the ocular trauma classification system. Primary repair was done and outcomes were assessed at one, three and six months. The final vision was categorized as per World Health Organization classification of visual impairment. Factors at presentation were evaluated for prognostic value towards visual outcome. Sixty-nine eyes with minimum one month follow-up were included for analysis. Statistical analysis was done using Univariate and Multivariate analysis. We found Grade IV visual acuity (<5/200) at presentation (64%) as the most important factor contributing to poor visual outcome. Statistically insignificant factors were time since injury, cataract, and presence of intraocular foreign body. Ocular survival was 97%. We concluded that initial visual acuity, hyphema, zone and length of injury, retinal detachment and vitreous hemorrhage are statistically significant factors affecting outcome in open globe injuries.

Trauma ocular contuso envolvendo o segmento posterior: qual a melhor conduta? / Blunt ocular trauma involving the posterior segment: which the best conduct?

Introdução: Trauma ocular contuso envolvendo o segmento posterior geralmente implica em mau prognóstico.Com o surgimento de técnicas cirúrgicas modernas houve uma mudança dramática no manejo dos olhos severamente traumatizados. Há controvérsias quanto ao melhor momento para realização da cirurgia de vitrectomia após um trauma ocular e quais casos se beneficiariam desse procedimento assim como do buckle de esclera. Objetivo: Relatar um caso de trauma ocular contuso envolvendo o segmento posterior e através de revisão bibliográfica descrever qual a melhor conduta nesse tipo de trauma, enfatizando controversas existentes na literatura quanto ao papel do buckle de esclera, da vitrectomia e o melhor momento para realização da vitrectomia.Metodologia: Será realizado um relato de caso de trauma ocular contuso envolvendo o segmento posterior.Foi ainda realizada uma revisão da literatura através dos seguintes portais de pesquisa: PubMed, Portal Capese Bireme. Conclusão: A conduta no trauma contuso envolvendo o segmento posterior deve ser adotada de acordo com as manifestações clínicas apresentadas. Nos casos em que os meios oculares estão opacos impossibilitando a visualização do segmento posterior, a realização da vitrectomia precocemente poderá ser útil. O papel do buckle de esclera ainda é inconclusivo. A realização de um estudo clínico, multicêntrico, randomizado com um tempo deacompanhamento mais prolongado é necessária.

Introduction: Blunt ocular trauma involving the posterior segment generally implies in bad prognostic. Withthe sprouting of modern surgical techniques there was a dramatical change in the handling of the severely traumatized eyes. There are controversies about the optimummoment for accomplishment of the vitrectomy surgery and wich cases would have benefit from this procedureas well as from the scleral buckling.Objective: To report a case of blunt ocular trauma involving the posterior segment and to demonstrate throughbibliographical revision which is the best management in this type of trauma, emphasizing controversies existingin the literature about the role of the scleral buckling, the role of the vitrectomy and the optimum moment foraccomplishment of the vitrectomy.Methodology: It is a case report about blunt ocular trauma involving the posterior segment. There was alsodone a revision of the literature carried through the following vestibules of research: PubMed, Portal Capesand Bireme. Conclusion: The management for cases of bluntocular trauma involving the posterior segment should be taken in accordance with the clinical manifestations presented. In the cases where the ocular media are opaque disabling the visualization of the posterior segment, itseems that early vitrectomy surgery can be useful. The role of the scleral buckling is still inconclusive. A multicentric, randomized, clinical trial seems justified.

Intralenticular metal foreign body: case report / Corpo estranho metálico intracristaliniano: relato de caso

Intralenticular foreign bodies comprise about 5 percent to 10 percent of all intraocular foreign bodies and can result in serious complications. The management depends on some factors like size, location, material type and the risk of infection. We present a patient with an intralenticular metal foreign body in the left eye that, following initial treatment with topical steroid and antibiotic, underwent lens aspiration with removal of the intralenticular foreign body and insertion of a posterior chamber intraocular lens with good visual outcome.

Os corpos estranhos intracristalinianos representam cerca de 5 a 10 por cento de todos os corpos estranhos intra-oculares. A conduta depende de alguns fatores, como: tamanho, localização, tipo de material e probabilidade de infecção. Relatamos um caso de um paciente com um corpo estranho metálico intracristaliniano no olho esquerdo que, após realizar tratamento inicial com esteróide e antibiótico tópicos, submeteu-se à aspiração do cristalino, retirada do corpo estranho e implante de lente intra-ocular com bom resultado visual.

Outcome of corneal scleral laceration in Yazd

The aim of this study is to define the epidemiologic characteristics and clinical profile and evaluation of final visual outcome of corneal scleral laceration. A prospective survey was conducted over a two year period from March 2000 to March 2002 on 79 consecutively admitted patients who underwent corneal scleral repairment at Yazd Eye Hospitals. This study included 79 eye injuries. Fifty nine of cases [74.7%] occurred in males and 20 cases [25.3%] in females. Mean age was 17.08 years. Left eye was more commonly involved [57%]. Initial VA was an important predictor of final VA. Good initial VA > 20/200 leading to excellent final VA. 40.6% of traumas occurred in the first decade of life. Injuries less than 10 mm and related to zone I and II predicted a good visual outcome. In this study endophthalmitis [5.1%] was much less likely to develop in eyes with primary repairment within 24 hours from the injury [1.5%] than in eyes being repaired after 24 hours [21.4%] and the difference was significant [P==0.016]. Significant predictive factors for final VA after corneal scleral injury include: initial VA, wound length, wound and location,, and the time of primary repair

Etiologia e tratamento inicial das perfurações oculares / Mechanism and primary treatment for ocular perforation

Foram estudadas 42 perfurações do globo ocular. Apenas um paciente apresentou trauma binocular. Identificamos com facilidade os fatores etiológicos. Como atendimento primário, a maioria foi levada a tratamento cirúrgico o mais rápido possível.

The authors have studied 42 perforating ocular injuries. Only one patient presented bilateral trauma. As the primary care, the majority undergone surgical repair as soon as possible. Preventive maesures are discussed.

Anestesia retrobulbar com catéter flexível de teflon em pacientes com comprimento axial ocular aumentado / Retrobulbar anesthesia with a flexible teflon catheter in patients with increased axial ocular lengt

Dentre as complicaçöes associadas à anestesia retrobulbar e peribulbar, perfuraçäo do globo ocular parece ser das mais importantes. Recente estudo ultrassonográfico demonstrou que, em pacientes submetidos à anestesia retrobulbar para cirurgia de catarata com comprimento axial normal, a ponta da agulha usada para injeçäo retrobulbar se encontrava muito próxima do globo ocular, as vezes até indentando sua parede. Tal fato pode se tornar extremamente perigosos em olhos com comprimento axial aumentado, como nos altos míopes. Demonstramos a eficácia e segurança do uso da técnica de anestesia retrobulbar com catéter flexível de Teflon em 15 pacientes com comprimento axial ocular ântero-posterior aumentado e candidatos à facectomia

Management of ocular trauma

Forty cases of ocular trauma in children were reviewed. The age of the patients ranged from 2 years to 12 years with a mean of 8 years and 6 months. 32 cases. [80%] needed surgical management and 8 cases 120%] were managed conservatively. Patients of penetrating ocular injuries [Group 1] had poor visual prognosis 6/18 or worse, as compared to blunt ocular trauma [Group 2] and ocular burns [Group 3] 6/6-6/18. Injuries involving the lens in the anterior segment or the posterior segment were associated with afar worse prognosis due to the problems of maintenance of binocular single vision. Children under 6 years had poor visual prognosis due to development of amblyopia. Education of the parents for adopting preventive measures at home and at the place of play would save these children as well as other children from ocular injuries in future

Prefuraçäo ocular em crianças / Penetrating ocular injuries in children

Os autores estudaram, prospectivamente, 174 crianças e adolescentes de um total de 473 casos com ferimento perfurante ocular, atendidos no Pronto Socorro de Oftalmologia do Hospital Säo Paulo - Escola Paulista de Medicina, com seguimento de 2 a 36 meses (x=9,5 meses). Observou-se um predomínio do sexo masculino (74,7 por cento), obedecendo uma proporçäo de 3:1. A córnea foi o local-escleral (30,3 por cento). A maioria das perfuraçöes se deveu a acidentes em ambiente doméstico (71,3 por cento), seeguida dos acidentes causados por violência (14,4 por cento), envolvendo objetos pérfuro-contundentes (28,7 por cento), contundentes (228,2 por cento) e pontiagudos (22,5 por cento). É discutida a relaçäo do prognóstico visual com o agente causal e achados pré-operatórios, bem como a alta incidência de atrofia ocular (25,8 por cento)

Vitrectomy for intra ocular foreign body removal.

Ten consecutive cases of perforating ocular injuries with retained intraocular foreign bodies over a period of 2 years were reviewed retrospectively in this study. All cases were operated upon by a 3 port pars plana vitrectomy and if necessary endolaser done. All ten cases (100%) were successful in terms of intraocular foreign body removal through the pars plana sclerotomy but ultimately we lost three [3] [30%] cases of which two had retinal detachments with P.V.R. D-3 preoperatively and the other had endophthalmitis. Of the seven (70%) successful cases four eyes (40%) had a post-operative vision of 6/12 or better while 2 [20%] had 6/24 and the last had 6/60 [10%]. Nine cases [90%] had a magnetic Intraocular foreign body. Various complications of Intraocular foreign bodies like vitreous haemorrhage, retinal incarceration, cataract and retinal detachment were noted preoperatively. Silicone oil was used in three (30%) cases. Sulfur Hexafluoride was used in 5 cases (50%). Endolaser photocoagulation was done in 7 cases (70%).

Ferida perfurante do globo ocular / Perforating trauma of eyeball

Os ferimentos oculares podem ser tratados em consultório, quando a perfuraçäo é pequena e o Seidel mínimo e no centro cirúrgico onde se completa o exame e se decide a cirurgia. Algumas regras para a conservaçäo e reposiçäo das iris säo discutidas. O autor descreve as manobras necessárias para o manejo de ferimentos corneanos, esclerais e corneo-esclerais. As feridas esclerais que se estendem para além de 7 mms. do limbo atingem a área retiniana e säo objeto de tratamento diferente

Trauma ocular penetrante grave e bilateral / Penetrating ocular trauma severe and bilateral

Seis casos de ferimentos oculares penetrantes, graves e bilaterais, foram analisados retrospectivamente quanto a epidemiologia, apresentaçäo clínica, tratamento e resultado visual final. Todos os casos foram decorrentes de acidentes automobilísticos em que os pacientes se encontravam no banco dianteiro dos veículos sem o uso de cintos de segurança. Somente 2 pacientes apresentaram traumatismos graves em outros órgäos, os demais apresentaram apenas ferimentos de face junto ao trauma ocular. Quando do trauma penetrante somente foi feita a reconstiruiçäo microscópica do globo ocular. Três olhos foram enucleados de imediato devido a perda total ou quase total do conteúdo intraocular, com laceraçöes que frequentemente se extendiam até o nervo óptico. Todos os olhos foram submetidos a vitrectomia pars plana e a outros procedimentos adicionais, dependendo de cada caso, entre 1 e 4 semanas após a reconstituiçäo inicial do globo ocular. A acuidade visual após a reconstituiçäo inicial do globo, mas antes da vitrectomia, era apenas de projeçäo luminosa no melhor olho. O tempo de seguimento pós-operatório variou de 3 a 18 meses. Todos os olhos operados obtiveram melhora da acuidade visual que variou de acordo com o tipo de lesäo pré-existente. A importância da vitrectomia nestes casos é demonstrada através de estudo experimental usando o modelo de Cleary- Ryan1 para trauma ocular penetrante
