Autofluorescence and spectral-domain optical coherence tomography of optic disk melanocytoma / Autofluorescência e tomografia de coerência óptica de domínio espectral do melanocitoma do disco óptico

The authors report fundus autofluorescence (FAF) and spectral-domain optical coherence tomography (OCT) findings of two consecutive patients who presented with optic disk melanocytoma (ODM). A retrospective study was performed by reviewing medical records and ophthalmic imaging examinations. Optical coherence tomography findings were sloped and brightly reflective anterior tumor surface, adjacent retinal desorganization and abrupt posterior optical shadowing. Vitreous seeds were found in one patient. Fundus autofluorescence revealed outstanding hypoautofluorescence at the tumor area and isoautofluorescence at the remaining retina. Optical coherence tomography findings of the reported cases are consistent with those reported in the reviewed literature. Fundus autofluorescence has been used in the assessment of choroidal melanocytic tumors, but not yet in melanocytomas. We assume that this is the first report of these findings and believe that when its pattern has become clearly defined, fundus autofluorescence will be a useful tool to avoid misdiagnosis in suspicious cases and for follow-up.

Os autores descrevem os achados do exame de autofluorescência do fundo de olho (AF) e da tomografia de coerência óptica (TCO) de domínio-espectral em dois pacientes consecutivos apresentando melanocitoma disco óptico (MDO) em um estudo retrospectivo, por revisão dos prontuários e exames oftalmológicos de imagem. Os achados no exame de tomografia de coerência óptica foram hiperrefletividade e elevação da superfície anterior da lesão, desorganização da retina adjacente, e, sombreamento óptico posterior. Sementes vítreas foram encontrados em um paciente. O exame de autofluorêscencia do fundo de olho revelou hipoautofluorescência marcante na área do tumor e isoautofluorescência nas demais áreas da retina. As características encontradas na tomografia de coerência óptica dos pacientes apresentados são consistentes com os achados relatados na literatura atual. A autofluorêscencia do fundo de olho tem sido utilizada na avaliação de tumores melanocíticos da coroide, mas ainda não em melanocitomas. Acreditamos que este seja a primeira descrição dos achados de autofluorêscencia do fundo de olho em pacientes com melanocitoma de disco óptico e que, quando seu padrão de tornar-se claramente definido, a autofluorêscencia do fundo de olho será uma ferramenta útil para evitar erros de diagnóstico em casos suspeitos.

Fundus autofluorescence in blunt ocular trauma.

PURPOSE: To describe the findings of fundus autofluorescence (FAF) imaging in patients with blunt ocular trauma. METHODS: In this non-interventional retrospective study, we reviewed medical records and imaging examination results. The data analyzed included gender, age, laterality, trauma etiology, time between trauma and imaging, visual acuity, changes in the retinal periphery, fundus examination results, and FAF imaging findings. FAF imaging was performed using a Topcon TRC-50DX Retinal Camera (Tokyo, Japan). RESULTS: Eight eyes from 8 patients were studied. The mean age was 27.6 years (range, 19-43 years). Men (n=7) were more frequently affected by blunt ocular trauma than women (n=1). Physical aggression was the most common trauma etiology (n=3), followed by accidents with fireworks (n=2). Other causes were car accidents (n=1), occupational trauma caused by a grinder (n=1), or being hit by a stone (n=1). Visual acuity ranged from 20/80 to light perception. Traumatic pigment epitheliopathy (TPE) was identified in 5 cases, choroidal rupture in 3 cases, subretinal hemorrhage in 3 cases, and Purtscher's retinopathy in 1 case. Hypoautofluorescence was observed in cases of choroidal rupture, recent subretinal hemorrhage, and intraretinal hemorrhage, and in two cases of TPE. Hyperautofluorescence was observed in cases of old subretinal hemorrhage and at the edge of the lesion in two cases of choroidal rupture. Mild hyperautofluorescence was observed in the posterior pole in Purtscher's retinopathy. Three cases of TPE exhibited hypoautofluorescence with diffuse hyperautofluorescent areas. CONCLUSION: FAF imaging is a non-invasive method for assessing changes in the posterior segment of the eye resulting from blunt ocular trauma. Furthermore, this technique provides valuable information. We described the findings of FAF imaging in cases of TPE, choroidal rupture, subretinal hemorrhage, and Purtscher's retinopathy.

Dobras de coroide / Choroidal folds

Dobras de coroide é considerado o achado fundoscópico mais prevalente nos casos de tumor orbitário. São ondulações no epitélio pigmentado da retina, membrana de Bruch, porção interna da coriocapilar e que, em alguns casos, podem acometer a retina neurossensorial, sendo então chamadas de dobras coriorretinianas. Diversas condições, oculares e sistêmicas, cursam com dobras de coroide e devem ser corretamente investigadas e, caso necessário, prontamente tratadas. Nesta revisão iremos abordar os aspectos gerais das dobras de coroide, enfatizando suas características nos seguintes exames de imagem: Retinografia, autofluorescência, angiofluoresceínografia e tomografia de coerência óptica.

Choroidal folds is considered the most prevalent funduscopic finding in cases of orbital tumors. They are ripples in the retinal pigment epithelium, Bruch's membrane, the inner portion of the choriocapillaris and in some cases, may affect the neurosensory retina, and then called chorioretinal folds. Several ocular and systemic conditions are associated with the finding and must be properly investigated and, if necessary, promptly treated. In this review we discuss the general aspects of choroidal folds, emphasizing their characteristic features in the following ophthalmological imaging tests: Retinography, fundus autofluorescence, fluorescein angiography and optical coherence tomography.

Retinal vasoproliferative tumor.

Retinal vasoproliferative tumor is a rare disease that has capillary hemangioma as the most frequent diferential diagnosis. The tumor is considered to be of reactive nature. It can be idiophatic or secondary to other ocular diseases such as: uveitis, retinitis pigmentosa, sickle cell disease, previous surgery and retinopathy of prematurity. Lesions with no exsudation or visual decrease can be observed. Lesions that need treatment can be managed by on or more modalities such as cryotherapy, a variety of lasers, surgical excision, radiation, and antiangiogenic intravitreal injections.

Bilateral choroidal neovascularization response to unilateral intravitreal Ranibizumab injection in a patient with angioid streaks / Resposta de neovascularização bilateral de coróide à injeção unilateral de Ranibizumabe intravítreo de paciente com estrias angióides

Report of a 48 year-old male with bilateral decrease in vision due to choroidal neovascularization secondary to angioid streaks. Best corrected visual acuity was 20/80 in the right eye and counting fingers at 2 meters on the left eye. Patient underwent intravitreal injection of Ranibizumab (Lucentis) in the eye with worse visual acuity. Fifteen days after treatment patient reported better visual acuity on the fellow eye, which was measured to be 20/25. Treatment result was evaluated with visual acuity and optical coherence tomography. The effect of ranibizumab was observed in the treated eye, but the fellow eye had complete resolution of the choroidal neovascularization complex. This result may be a response to systemic absorption of the medication.

Os autores descrevem paciente do sexo masculino, 48 anos, com diminuição visual bilateral há 15 dias por membrana neovascular sub-retiniana secundária a estrias angióides. A acuidade visual com melhor correção no olho direito era 20/80 e no olho esquerdo de conta dedos a 2 metros. Submetido à injeção intravítrea de Ranibizumabe (Lucentis) no olho com pior acuidade visual. Após 15 dias do tratamento, referiu melhora acentuada da visão no olho contralateral com visão de 20/25. O resultado foi avaliado por meio da acuidade visual e da tomografia de coerência óptica. O efeito do ranibizumabe foi observado no olho tratado, mas no olho contralateral houve completa resolução do complexo da membrana neovascular sub-retiniana. Levanta-se a hipótese de que esse resultado possa ser atribuído à absorção sistêmica da medicação.

Retinal vasoproliferative tumor / Tumor vasoproliferativo da retina

Retinal vasoproliferative tumor is a rare disease that has capillary hemangioma as the most frequent diferential diagnosis. The tumor is considered to be of reactive nature. It can be idiophatic or secondary to other ocular diseases such as: uveitis, retinitis pigmentosa, sickle cell disease, previous surgery and retinopathy of prematurity.

O tumor vasoproliferativo da retina é uma lesão rara, cujo principal diagnóstico diferencial é o hemangioma capilar da retina. O tumor tem natureza reacional. Pode ser idiopático ou secundário a outras doenças como: uveítes, retinose pigmentar, retinopatia da anemia falciforme, cirurgia prévia e retinopatia da prematuridade. Lesões sem exsudação ou baixa visual podem ser observadas. Quando há indicação de tratamento este pode ser feito pela crioterapia, vários tipos de lasers, excisão cirúrgica, radioterapia e injeções intravítrea de antiangiogênicos, isoladamente ou em associação.

Inflamação esclerosante idiopática da órbita: estudo clinico-patológico / Idiopathic sclerosing orbital inflammation: clinicopathologic study

OBJETIVO: Descrever oito casos de inflamação esclerosante idiopática da órbita, incluindo a análise clínica e histopatológica. MÉTODOS: Estudo retrospectivo através do livro de registros do Laboratório de Patologia Ocular (LPO) do Hospital Universitário Professor Edgard Santos, Universidade Federal da Bahia, no período de 1974 a 2010. Além de revisão de lâminas de todos os casos e das imagens clínicas e de exames complementares recuperadas dos arquivos pessoais dos autores. RESULTADOS: Dentre o total de espécimes submetidos ao LPO (7546) apenas 8 casos receberam diagnóstico final de inflamação esclerosante idiopática da órbita. Em todos os casos houve piora ou deterioração da acuidade visual à despeito do tratamento, com exceção de um, que permaneceu com a mesma visão (percepção luminosa). Em nosso estudo, observamos envolvimento orbitário predominantemente apical. Todos os nossos pacientes foram submetidos à biópsia incisional com finalidade diagnóstica. Também submeteram-se à corticoterapia e em um caso foi associada à radioterapia anti-inflamatória; em dois destes casos, foi utilizado também ciclofosfamida. Dois pacientes com acuidade final sem percepção luminosa tiveram que ser submetidos à exenteração parcial da órbita para tratamento de dor incontrolável. CONCLUSÃO: A inflamação esclerosante orbitária idiopática permanece como uma doença pouco conhecida, de péssimo prognóstico visual.

PURPOSE: To describe the clinical and histopathologic findings of eight cases of idiophatic sclerosing orbital inflammation. METHODS: A retrospective study from the file of the Ophthalmic Pathology Laboratory of the Hospital Universitário Professor Edgard Santos, Federal University of Bahia, during the period from 1974 to 2010. The clinical data, computed tomography and histopathologic sections obtained by biopsy of all cases were reviewed. RESULTS: From 10312 specimens submitted to the Ophthalmic Pathology Laboratory, eight (0,08%) had a final diagnosis of idiopathic sclerosing orbital inflammation. All cases were unilateral and in all of them vision acuity decreased or was lost despite of treatment, except for one case that remained with light perception as in the first examination. A predominance of diffuse orbital involvement was observed by computed tomography. Histopathologic evaluation disclosed dense fibrosis and collagen deposition with paucicellular inflammation in all cases. All patients were treated by immunosupression with steroids and one case had an association of anti-inflammatory radiotherapy. Two patients were also treated with ciclophosphamide. Partial orbital exenteration was necessary in two cases due to uncontrollable pain. CONCLUSION: Idiopathic sclerosing orbital inflammation remains as a disease with poor response to treatment ans a very bad visual prognosis.

An outbreak of forty five cases of Pseudomonas aeruginosa acute endophthalmitis after phacoemulsification / Surto de quarenta e cinco casos de endoftalmite aguda por Pseudomonas aeruginosa após facoemulsificação

PURPOSE: To describe an outbreak of Pseudomonas aeruginosa endophthalmitis post cataract surgery. Clinical findings, treatment and outcome are discussed. METHODS: Clinical charts review of forty-five patients treated for endophthalmitis in a two-day period. The patients underwent primary vitrectomy, anterior chamber irrigation and intravitreous antibiotic injection. Cultures from vitreous and anterior chamber samples were performed in all patients. RESULTS: Forty-five patients (twenty-three men and twenty-two women) were identified. The average age was 71.2 years (range, 56-83 years). The right eye (62%) was affected more often than the left eye (38%). The median interval between surgery and endophthalmitis onset was 5.5 days (range, 5-6 days). The visual acuity at the diagnosis was better than 20/40 in one patient (2%), from 20/40 to 20/200 in one patient (2%), from 20/400 to counting fingers in two patients (4%), hand movements in eleven patients (24%), and light perception in thirty patients (68%). Pseudomonas aeruginosa was the isolated agent in twenty-six vitreous samples and in three anterior chamber samples. Overall, one patient (2%) achieved a final visual acuity better than 20/40; eight patients (18%) achieved a final visual acuity from 20/40 to 20/200; six patients (13%) achieved a final visual acuity from 20/400 to counting fingers; eleven patients (25%) achieved a final acuity of hand movements; thirteen patients (29%) achieved a final acuity of light perception and six (13%) patients had no light perception at the last examination. None of these eyes underwent evisceration or enucleation in a three-month follow-up period. CONCLUSION: Even with all the safety that cataract surgery has achieved, today, endophthalmitis remains a risk and a fearful complication of this procedure. In the present study, it was impossible to identify the source of the outbreak.

OBJETIVO: Descrever surto de endoftalmite por Pseudomonas aeruginosa após facectomia. Os achados clínicos, o tratamento e o resultado são discutidos. MÉTODOS: Revisão dos prontuários de quarenta e cinco pacientes tratados para endoftalmite em um período de dois dias. Todos os pacientes foram tratados por vitrectomia primária, irrigação da câmara anterior e injeção vítrea de antibióticos. Culturas do vítreo e de amostras de câmara anterior foram realizadas em todos os pacientes. RESULTADOS: Quarenta e cinco pacientes (23 homens e 22 mulheres) foram identificados. A idade média foi 71,2 anos (variação, 56-83 anos). O olho direito (62%) foi mais afetado do que o esquerdo (38%). O intervalo médio entre a cirurgia e a apresentação da endoftalmite foi de 5,5 dias (intervalo de 5-6 dias). A acuidade visual no momento do diagnóstico foi melhor que 20/40 em um paciente (2%), de 20/40 a 20/200 em um paciente (2%), de 20/400 para contar dedos em dois pacientes (4%), movimento de mão em onze pacientes (24%), percepção de luz em trinta pacientes (68%). Pseudomonas aeruginosa foi o agente isolado em 26 amostras de vítreo e em três amostras da câmara anterior. No geral, um paciente (2%) obteve acuidade visual final melhor que 20/40, oito pacientes (18%) obtiveram acuidade visual final de 20/40 a 20/200, seis pacientes (13%) obtiveram acuidade visual final de 20/400 para contar os dedos; onze pacientes (25%) obtiveram acuidade visual final de movimento de mão; treze pacientes (29%) obtiveram acuidade visual final de percepção de luz e seis (13%) pacientes não havia percepção luminosa no último exame. Nenhum olho foi submetido à evisceração ou enucleação em três meses de acompanhamento. CONCLUSÃO: Mesmo com toda a segurança da cirurgia de catarata nos dias atuais, endoftalmite permanece um risco e uma complicação temível deste procedimento. No presente estudo não foi possível identificar a fonte do surto.

Optical coherence tomography findings in acute phase of branch retinal artery occlusion: case report.

PURPOSE: to report a case of branch retinal artery occlusion in the acute phase, using optical coherence tomography to evaluate the morphologic changes. A 27 year-old man had a sudden superior scotoma in the right eye, with fundus examination compatible with inferior temporal branch retinal artery obstruction. The optical coherence tomography revealed increase in thickness and hyper-reflectivity of the inner retinal layers in affected area, with decreased reflectivity of photoreceptor and retinal pigment epithelial layers. The optical coherence tomography findings are consistent with intracellular edema, and not with secondary vascular leakage of extracellular fluid, according to histopathological theories of retinal ischemia and necrosis that occurs after retinal artery occlusion.

O objetivo é demonstrar alterações morfológicas retinianas por meio da tomografia de coerência óptica na oclusão de ramo de artéria central da retina na fase aguda. Homem de 27 anos apresentando escotoma súbito no campo superior de olho direito, com exame fundoscópico compatível com oclusão de ramo ínfero-temporal da artéria central da retina. A tomografia de coerência óptica revelou aumento da espessura e hiperrefletividade das camadas internas da retina, com redução da refletividade das camadas de fotorreceptores e epitélio pigmentar da retina. Os achados na tomografia de coerência óptica são compatíveis com edema intracelular, e não com fluido extracelular secundário a extravasamento vascular, reforçando teorias histopatológicas da isquemia e necrose retiniana, que ocorrem após oclusão arterial retiniana.

Metástase orbital como primeira manifestação clínica de hepatocarcinoma / Orbital metastasis as the first clinical manifestation of hepatocellular carcinoma

Mulher de 59 anos apresentava proptose e dor em olho esquerdo com trinta dias de duração. A tomografia computadorizada (TC) de órbitas mostrava massa em órbita esquerda com destruição óssea e invasão intracraniana. A biópsia da lesão revelou hepatocarcinoma. Na investigação sistêmica, a TC de abdômen evidenciou presença de tumor hepático. Iniciou tratamento quimioterápico, evoluindo com redução significativa da massa orbital, porém cerca de quatro meses após o fim da quimioterapia voltou a apresentar aumento da lesão orbital vindo a óbito dezenove meses após o diagnóstico.

A fifty nine years old female presented a painful proptotic left eye for thirty days. Computed thomography of the orbits disclosed an orbital mass associated with osteolysis and intracranial invasion. Biopsy of the orbital tumor revealed the diagnosis of hepatocellular carcinoma. Computed tomography showed the liver as the primary site of the tumor. Chemoterapy induced a significativ reduction of the orbital tumor. After four months, the orbital tumor increased its size and the pacient died ninetheen months after the diagnosis.

Papel da imunoistoquímica no diagnóstico das alterações oculares na leishmaniose tegumentar americana: relato clínico-patológico de cinco casos / Role of imunohistochemistry in the diagnosis of ocular lesions in mucocutaneous leishmaniasis: report of five cases

OBJETIVO: Descrever os achados clínicos, histopatológicos e imunoistoquímicos de cinco pacientes portadores de leishmaniose tegumentar americana com manifestações oftalmológicas. MÉTODOS: Estudo retrospectivo, no período de quatro anos, compreendendo análise dos prontuários de pacientes do Hospital Universitário Professor Edgard Santos e das lâminas de histopatologia e do estudo imunoistoquímico. RESULTADO: O sintoma mais frequente foi a hiperemia conjuntival (2/5), seguida por lesão crostosa palpebral (1/5), leucoplasia conjuntival (1/5) e prurido ocular (1/5).Todos os pacientes foram submetidos à biópsia. O estudo histológico evidenciou inflamação crônica (3/5) e hiperplasia pseudoepiteliomatosa (2/5). Todos os pacientes com aspecto histopatológico de hiperplasia pseudoepiteliomatosa apresentaram resultado positivo para leishmaniose pela imunoistoquímica (anticorpo policlonal antileishmania). CONCLUSÃO: Devido ao polimorfismo das manifestações oculares da leishmaniose tegumentar americana, à inespecificidade do quadro histopatológico e à grande dificuldade de visualização de amastigotas na coloração hematoxilina-eosina, a biópsia com estudo imunoistoquímico contribuiu para a confirmação diagnóstica.

PURPOSE: To describe the clinical, histopathological and immunoistochemical findings of ocular leishmaniasis in five patients presenting positive Montenegro reaction. METHODS: Retrospective study in four years of the clinical charts, histopathologic and immunoistochemic study of the material obtained by biopsy of ocular lesions in five patients with positive Montenegro reaction. RESULTS: The most frequent clinical findings was conjunctival hyperemia (2/5), followed by crusting lid lesion (1/5), conjunctival leukoplakia (1/5) and ocular itching (1/5). The histopathological study disclosed chronic inflammation (3/5) and pseudoepitheliomatous hyperplasia (2/5). The all patients that presented pseudoepitheliomatous hyperplasia in the biopsy material also presented immunohistochemical positivity for polyclonal antibody anti-leishmania. CONCLUSION: The immunoistochemical study was contribuitory for the diagnosis of ocular leishmaniasis in the five patients of this study.

[Orbital eosinophilic granuloma]. / Granuloma eosinofílico orbitário.

PURPOSE: To report the retrospective experience of a reference center in the diagnosis and treatment of orbital eosinophilic granuloma. METHODS: A review of the files in the Opththalmic Pathology Laboratory, of the Hospital Universitário Professor Edgard Santos, Universidade Federal da Bahia, between 1974 and 2004, was conducted to identify cases of orbital eosinophilic granuloma. Data of diagnosis and treatment were collected. The hematoxilin and eosin stained sections were reviewed. RESULTS: Three cases with ages of 1, 6 and 11 years were retrieved. In none of them the clinical diagnosis of eosinophilic granuloma was suspected. All patients underwent diagnostic biopsy with characteristic histological aspect. In one case a orbital computed tomography after biopsy exhibited typical findings. All patients improved with systemic steroids./ CONCLUSIONS: This is a rare disease, with a difficult clinical diagnosis if radiological evaluation is not available. In spite of its aggressiveness at presentation, the disease shows good response to systemic steroids.

[Cystic orbital teratoma: clinicopathologic study: case report]. / Teratoma cístico da órbita: estudo clínico patológico: relato de caso.

We report on a case of an congenital orbital tumor of impressive size, occurring in a newborn. The patient underwent orbital exenteration with a histopathologic diagnosis of cystic teratoma. The clinicopathological aspects of such a rare disease are commented.
