ABSTRACT

RESUMO Objetivo: Analisar o perfil clínico de pacientes em acompanhamento dermatológico encaminhados para avaliação oftalmológica. Métodos: A amostra foi composta de pacientes dermatológicos encaminhados para avaliação oftalmológica, nos anos de 2016 e de 2017. Estudou-se a concomitância de doenças dermatológicas com as afecções oftalmológicas por meio da coleta simultânea do histórico dermatológico (prontuários registrados com dados gerais e diagnóstico) e de dados da consulta oftalmológica após o encaminhamento. Resultados: Foram avaliados pela oftalmologia 224 pacientes, sendo 65% do sexo feminino, 80% caucasianos, com idade variando entre 1 mês e 85 anos. As situações cujo encaminhamento foi mais prevalente foram psoríase, lúpus, vitiligo e rosácea (18,3%, 13,8%, 12,9% e 10,7%, respectivamente). Fototerapia crônica e uso de hidroxicloroquina representaram 35,7% e 22,3% dos pacientes. Casos de neurofibromatose, micose fungoide, líquen plano, neoplasias de pele, atopias, pênfigo e esclerodermia também estiveram presentes. Cegueira legal foi detectada em 6%, e deficiências visuais ligadas a afecções dermatológicas foram verificadas em 16,5% dos casos. As alterações oculares mais prevalentes foram catarata (18,9%), blefarite (15,9%), pterígio (5,3%) e conjuntivite (5,3%). Conclusão: Encontrou-se elevada frequência de alterações oftalmológicas em uma população de pacientes com doenças dermatológicas. Assim, o estudo e a análise de manifestações oculares em pacientes dermatológicos podem auxiliar na detecção precoce e na prevenção de complicações.


ABSTRACT Objective: To analyze the clinical profile of patients under dermatological care and referred to ophthalmological evaluation. Methods: The sample comprised dermatology patients referred to ophthalmological evaluation in 2016 and 2017. The simultaneous occurrence of skin and ophthalmic diseases was studied, by collecting dermatological history (medical records containing general data and diagnosis) and ophthalmic consultation data following referral. Results: A total of 224 patients were assessed, 65% were female, 80% were white, and age varied between one month and 85 years. The conditions more often referred were psoriasis, lupus, vitiligo and rosacea (18.3%, 13.8%, 12.9% and 10.7%, respectively). Chronic phototherapy and use of hydroxychloroquine were observed in 35.7% and 22.3% of patients, respectively. Cases of neurofibromatosis, mycosis fungoides, lichen planus, skin cancer, atopic dermatitis, pemphigus and scleroderma were also reported. Legal blindness was detected in 6% and visual impairment related to skin conditions in 16.5% of patients. The most prevalent ocular changes were cataracts (18.9%), blepharitis (15.9%), pterygium (5.3%) and conjunctivitis (5.3%). Conclusion: A high frequency of ophthalmic changes in a population of dermatological patients was found. In this context, studying and analyzing ocular manifestations in dermatological patients could be useful in early detection and prevention of complications.

ABSTRACT

RESUMEN La Organización Mundial de la Salud declaró el 11 de marzo del año 2020 pandemia por la COVID-19, enfermedad causada por el SAR-COV-2. Al no existir medicamentos efectivos disponibles para esta infección viral, muchos han sido los esfuerzos de las políticas de salud para lograr un control adecuado de la fuente de infección, la transmisión y la protección en poblaciones susceptible, mediante las cuarentenas obligatorias como medida oportuna de prevención. Hasta el momento la presencia de conjuntivitis viral y el riesgo de contagio por vía ocular son datos mencionados en la literatura internacional en el curso de diversas investigaciones. Se conoce que el virus puede aislarse en la lágrima y en la conjuntiva, y que su transmisibilidad por las secreciones oculares es posible. La actual pandemia del coronavirus es una emergencia sanitaria mundial y muchos países han sido actualmente afectados con miles de fallecidos. Se realizó una búsqueda de diversos artículos publicados, con el objetivo de conocer las manifestaciones oculares de la COVID-19 reportadas por diferentes investigadores. Se utilizó la plataforma Infomed, específicamente la Biblioteca Virtual de Salud(AU)


ABSTRACT COVID-19, a disease caused by SARS-CoV-2, was declared pandemic by the World Health Organization on 11 March 2020. In the absence of effective medications for this viral infection, many have been the efforts made by health policies to adequately control the source of infection and transmission, and to protect susceptible populations through compulsory quarantine as a timely prevention measure. Viral conjunctivitis and risk of contagion via the ocular route have been mentioned in a variety of international studies contained in the bibliography about the topic. It has been found that the virus may be isolated from tears and from the conjunctiva, and that it may be transmitted via ocular secretion. The current coronavirus pandemic is a world health emergency causing thousands of deaths in many countries. A search was conducted for published papers to identify the ocular manifestations of COVID-19 reported by researchers. Use was made of the platform Infomed, specifically the Virtual Health Library(AU)

ABSTRACT

Resumo Objetivo: Analisar a prevalência de alterações na fundoscopia de pacientes portadores de Diabetes Mellitus (DM) e/ou Hipertensão Arterial Sistêmica (HAS) encaminhados ao Serviço de Referência de Oftalmologia, localizado em uma Unidade Básica de Saúde do município de Patos, Paraíba (PB). Metodos: Estudo de caráter descritivo, transversal e com abordagem quantitativa, que envolveu um total de 22 pacientes. Para a coleta de dados, foi utilizado um questionário sobre a saúde ocular. Além disso, os integrantes da pesquisa participaram do teste da acuidade visual de Snellen e acuidade visual para perto, da medida da pressão intra-ocular e do exame da oftalmoscopia direta. Os que obtiveram pior acuidade visual foram conduzidos para a realização de retinografia. Os dados foram avaliados através de análises estatísticas utilizando o Statistical Package for the Social Sciences - SPSS. Resultados: Do total de 22 pacientes, 11 foram submetidos ao exame de retinografia. Destes, 36,3 % eram apenas diabéticos; 27,4% eram apenas hipertensos e 36,3% eram diabéticos e hipertensos. As principais alterações encontradas foram retinopatia diabética, retinopatia hipertensiva, catarata, glaucoma, nevus de coroide, retinose pigmentar e estafiloma peripapilar. Conclusão: Percebe-se que DM e HAS tem grande impacto negativo sobre a saúde ocular. Para diminuir esse efeito nocivo é necessário que o exame de fundo de olho seja realizado anualmente com a finalidade de diagnosticar precocemente certas patologias e evitar complicações futuras, culminando em menores custos para o sistema de saúde e mais qualidade de vida para os pacientes.


Abstract Objective: To analyze the prevalence of alterations in funduscopy of patients with Diabetes Mellitus (DM) and/or Systemic Arterial Hypertension (SAH) referred to the Ophthalmology Reference Service, located in a Basic Health Unit of the city of Patos, Paraíba). Methods: A descriptive, cross-sectional study with a quantitative approach, which involving a total of 22 patients. For data collection, a questionnaire on ocular health was used. In addition, the research members participated in the Snellen visual acuity test and visual acuity near, intraocular pressure measurement and direct ophthalmoscopy examination. Those who obtained worse visual acuity were conducted for retinography. The data were evaluated through statistical analysis using the Statistical Package for the Social Sciences - SPSS. Results: Of the total of 22 patients, 11 were submitted to retinography. Of these, 36.3% were diabetics only; 27.4% were hypertensive only and 36.3% were diabetic and hypertensive. The main alterations found were diabetic retinopathy, hypertensive retinopathy, cataract, glaucoma, choroidal nevus, pigmentary retinitis and peripapillary staphyloma. Conclusion: It is noticed that DM and SAH have a great negative impact on ocular health. To reduce this harmful effect it is necessary that the fundus eye exam be performed annually for the purpose of early diagnosis of certain pathologies and avoid future complications, culminating in lower costs for the health system and more quality of life for patients.

ABSTRACT

Resumo A doença de Lyme é uma infecção sistêmica causada pela espiroqueta Borrelia burgdorferi e transmitida pelo carrapato do gênero Ixodes sp. e espécie Amblyomma cajennense. A doença costuma se manifestar em três estágios clínicos distintos, que podem variar de acordo com as características de cada hospedeiro. O objetivo deste trabalho é relatar o caso de uma paciente de 33 anos com doença de Lyme que apresentou como manifestações neuroftalmológicas diplopia, lagoftalmo paralítico e ceratite punctata, com exames laboratoriais negativos. Embora a espiroqueta Borrelia burgdorferi tenha maior tropismo pelos tecidos da pele, sistema nervoso e articulações, o acometimento ocular não deve ter sua importância diminuída, sendo descrito neste relato de caso, que abordou os aspectos mais pertinentes à doença para auxiliar seu diagnóstico e tratamento.


Abstract Lyme disease is a systemic infection caused by the spirochete Borrelia burgdorferi and transmitted by the tick of the genus Ixodes sp. and species Amblyomma cajennense. The disease usually manifests itself in three distinct clinical stages, which may vary according to the characteristics of each host. The objective of this paper is to report the case of a 33-year-old patient with Lyme disease who presented as neuro-ophthalmological manifestations diplopia, paralytic lagophthalmos and punctate keratitis, with negative laboratory tests. Although the spirochete Borrelia burgdorferi has a greater tropism in the tissues of the skin, nervous system and joints, the ocular involvement should not be diminished, being described in this case report, which approached the most pertinent aspects to the disease to aid its diagnosis and treatment.

ABSTRACT

Resumo Objetivos: Identificar e descrever as alterações oculares em idosos com HIV ou aids através de exame oftalmológico. Avaliar a associação entre as alterações oculares encontradas e o nível de linfócitos T CD4, tempo da terapia antirretroviral, características demográficas e faixa etária. Métodos: Série de 40 casos de pacientes idosos com HIV examinados nos serviços de oftalmologia e imunologia do Hospital Universitário Gaffrée e Guinle (HUGG) de janeiro de 2017 a junho de 2018. Foi realizado o seguinte exame oftalmológico: anamnese, acuidade visual, motilidade ocular, reflexo pupilar, biomicroscopia, tonometria de aplanação e fundoscopia. As análises estatísticas foram realizadas pelo SPSS 20.0. Resultados: A média de idade dos 40 pacientes foi 64,7 anos (dp: 5,1) e o diagnóstico de infeção pelo HIV foi em média há 16.6 anos (dp:7). A maioria dos pacientes examinados possui visão normal (n=22; 55%) e pressão intraocular normal (entre 11 e 21 mmHg). As principais queixas dos pacientes durante a anamnese foram: embaçamento visual (50%), redução da acuidade visual (47.5%), prurido ocular (27.5%), lacrimejamento (25%) e ardência (25%). As alterações biomicroscópicas mais frequentes foram catarata (92.5%), seguida de olho seco (32.5%). Na fundoscopia encontrou-se 43,8 % de alterações da vascularização retiniana, 43.8 % de alterações relacionadas ao nervo óptico e 31,3% relacionadas ao pólo posterior da retina. Conclusão: Alterações oculares foram comuns e podem ser justificadas pela: senilidade, estado inflamatório gerado pela infecção crônica do HIV, efeitos adversos da Terapia antirretroviral prolongada e senescência biológica precoce associada a infecção do HIV.


Abstract Objectives: Identify and describe ocular changes in elderly with HIV or aids through ophthalmological examination. Evaluate the association between ocular alterations and the level of TCD4 lymphocytes, time of antiretroviral therapy, demographic characteristics and age range. Methods: Case series of 40 elderly patients with HIV infection. The study was carried out at the ophthalmology and immunology outpatient clinics of the Gaffrée and Guinle University Hospital (HUGG) from january 2017 to june 2018. The patients were attended at the ophthalmology clinic and underwent a ophthalmological exam including: anamnesis, visual acuity, ocular motility, pupillary reflex, biomicroscopy, aplanation tonometry and fundoscopy. Statistical analyses were performed using SPSS 20.0. Results: The average of the 40 patients was 64.7 years (sd: 5.1), aged between 60 and 78 years, and the average time of HIV infection was 16.6 years (sd: 7 years). Most of the patients examined had normal vision (55%) and normal intraocular pressure (between 11 and 21 mmHg). The main complaints of patients during anamnesis were visual blurring (50%), visual acuity reduction (47.5%), ocular itchiness (27.5%), tearing (25%) and burning (25%).The most frequent changes in biomicroscopy were: cataract (92.5%) and dry eye (32.5%). Funduscopy found 43.8% of retinal vascularization alterations, 43.8% of alterations related to the optic nerve and 31.3% related to retinal posterior pole. Conclusion: Ocular changes were common and can be explained by senility, inflamatory changes caused by chronic HIV infection, adverse effects of antiretroviral therapy and early biological ageing associated to HIV infection.

ABSTRACT

Resumo Doença do Enxerto-versus-hospedeiro (do inglês Graft-versus-Host Disease - GVHD) é uma complicação importante e com altas taxas de morbidade e mortalidade nos pacientes submetidos ao transplante alogênico de células-tronco hematopoiéticas. O acometimento ocular, denominado GVHD ocular, pode acometer todas as estruturas dos olhos, porém a unidade lacrimal (glândulas lacrimais e superfície ocular) é o principal alvo da resposta inflamatória mediada por células T doadas. O desenvolvimento de doença do olho seco grave é a principal manifestação clínica ocular, e a associação de diversas opções terapêuticas se faz necessário. O objetivo desta revisão é descrever as manifestações clínicas, os critérios diagnósticos, o impacto na qualidade de vida, o tratamento atual e as perspectivas desta doença, que precisa de um acompanhamento multidisciplinar.


Abstract Graft-versus-host Disease (GVHD) is a major complication with high morbidity and mortality rates on patients undergoing hematopoietic stem cell transplantation. The ocular involvement, named ocular GVHD, may affect all structures of the eyes, but the lacrimal unit (lacrimal glands and ocular surface) is the main target of the inflammatory response mediated by the donor T cells. The development of dry eye disease is the main clinical ocular manifestation, and the association of a variety of therapeutics options is necessary. The aim of the review is to describe the clinical manifestations, diagnostic criteria, impact in quality of life, the current treatment and future perspectives of this disease that demands a multidisciplinary follow-up.

ABSTRACT

ABSTRACT Purpose: We aimed to report the ocular manifestations observed in patients with psoriasis. Methods: Patients were included and referred to our ophthalmology clinic from dermatology clinics of Universidade do Estado do Pará between October 2013 and August 2014. Clinical interviews were conducted to identify relevant epidemiological data, clinical features, and treatment details, and data were recorded using the same protocol. Subsequent dermatological examinations were performed and disease severity was rated using the Psoriasis Area and Severity Index and the Dermatological Life Quality Index. Complete eye examination was conducted, including visual acuity, biomicroscopy, tonometry, fundoscopy, Schirmer I test, tear breakup time, rose bengal staining, ocular surface disease index, and glaucoma tests. Results: In total, we included 43 patients with psoriasis and 86 controls. Patients with psoriasis had statistically higher incidences of dry eye (16.28%), likely dry eye (32.56%), and blepharitis (16.28%). Furthermore, the rose bengal and ocular surface disease tests were more abnormal in patients with psoriasis (p<0.05). Conclusions: Patients with psoriasis should undergo regular eye exams, regardless of risk factors, to monitor for the progression of symptomatic or asymptomatic ocular manifestations.


RESUMO Objetivos: Relatar as manifestações oculares observadas em pacientes com psoríase atendidos no Ambulatório de Dermatologia da X e encaminhados ao Y, no período de outubro de 2013 a agosto de 2014. Métodos: A amostra foi constituída por um grupo composto por 43 pacientes com psoríase e um grupo controle com 86 pacientes sem psoríase. Foi realizada uma entrevista clínica com dados epidemiológicos, aspectos clínicos da doença e terapia empregada, sendo todas as informações registradas em protocolo próprio. Posteriormente, realizou-se o exame dermatológico, no qual foi avaliado o índice de gravidade da Psoríase por área (PASI) e índice dermatológico de qualidade de vida (DLQI), e o exame oftalmológico completo, incluindo: Acuidade Visual, Biomicroscopia, Tonometria, Fundoscopia, Teste de Schirmer I, Tempo de Ruptura do Filme Lacrimal (TBUT), rosa bengala, índice de doença da superfície ocular (OSDI) e exames para glaucoma. Resultados: Observou-se que nos pacientes com psoríase houve frequência estatisticamente maior de envolvimento ocular, como olho seco (16,28%), provável olho seco (32,56%) e blefarite (16,28%). Além disso, os valores do rosa bengala e do OSDI apresentaram-se mais alterados nos pacientes com psoríase (p<0,05). Conclusão: Dessa forma, sugere-se que esses pacientes realizem exames oftalmológicos periódicos, já que as manifestações oculares podem progredir sem sintomatologia e ocorrer independentemente de fatores de risco.

ABSTRACT

Abstract Introduction: The proximity of the paranasal sinuses to the orbit and its contents allows the occurence of injuries in both primary or revision surgery. The majority of orbital complications are minor. The major complications are seen in 0.01-2.25% and some of them can be serious, leading to permanent dysfunction. Objective: The aim of this study was to determine the risk and type of ophthalmic complications among patients operated due to a chronic rhinosinusitis. Methods: This is a retrospective study of 1658 patients who underwent endoscopic sinus surgery for chronic rhinosinusitis with or without polyps or mucocele. Surgeries were performed under general anesthesia in all cases and consisted of polyps' removal, followed by middle metal antrostomy, partial or complete ethmoidectomy, frontal recess surgery and sphenoid surgery if necessary. The ophthalmic complications were classified according to type, frequency and clinical findings. Results: In our material 32.68% of the patients required revision surgery and only 10.1% had been previously operated in our Department. Overall complications occurred in 11 patients (0.66%). Minor complications were observed in 5 patients (0.3%) with the most frequent being periorbital ecchymosis with or without emphysema. Major complications were observed in one patient (0.06%) and were related to a lacrimal duct injury. Severe complications occurred in 5 cases (0.3%), with 2 cases and referred to a retroorbital hematoma, optic nerve injury (2 cases) and one case of extraocular muscle injury. Conclusions: Orbital complications of endoscopic nasal surgery are rare. The incidence of serious complications, causing permanent disabilities is less than 0.3%. The most important parameters responsible for complications are extension of the disease, previous endoscopic surgery and coexisting anticoagulant treatment.


Resumo Introdução: A proximidade dos seios paranasais à órbita e seu conteúdo tornam possível a ocorrência de lesões tanto na cirurgia primária como na de revisão. A maioria das complicações orbitais são menores. As maiores são observadas em 0,01%-2,25% e algumas delas podem ser graves levando a disfunção permanente. Objetivo: O objetivo deste estudo foi identificar o risco e o tipo de complicações oftalmológicas em pacientes operados devido a rinossinusite crônica. Método: Foi realizado um estudo retrospectivo com 1.658 pacientes submetidos a cirurgia endoscópica sinusal devido a rinossinusite crônica com ou sem pólipos ou mucocele. As cirurgias foram realizadas sob anestesia geral em todos os casos e consistiram de remoção de pólipos, seguida de antrostomia meatal média ou etmoidectomia parcial ou completa, cirurgia de recesso frontal e cirurgia de esfenoide se necessário. As complicações oftalmológicas foram classificadas de acordo com o tipo, frequência e achados clínicos. Resultados: Em nosso material 32,68% dos pacientes necessitaram de cirurgia de revisão e apenas 10,1% haviam sido anteriormente operados em nosso departamento. As complicações gerais ocorreram em 11 pacientes (0,66%). Complicações menores foram observadas em 5 pacientes (0,3%), sendo que a mais frequente foi equimose periorbital com ou sem enfisema. Complicações maiores foram observadas em um paciente (0,06%) e atribuída à lesão do ducto lacrimal. Complicações graves ocorreram em 5 casos (0,3%) e foram referidas como hematoma retrorbital (2 casos), lesão do nervo óptico (2 casos) e um caso de lesão muscular extraocular. Conclusões: As complicações orbitais da cirurgia endoscópica nasal são raras. A incidência de complicações graves que causam incapacidade permanente é de menos de 0,3%. Os parâmetros mais importantes responsáveis por complicações são extensão da doença, cirurgia endoscópica anterior e tratamento anticoagulante coexistente.

ABSTRACT

Introducción: el glaucoma neovascular es un tipo de glaucoma secundario frecuente en los pacientes diabéticos, se produce por la formación de una membrana fibrovascular a nivel del ángulo camerular, como consecuencia de un estímulo angiogénico producido por enfermedades que generan isquemia ocular. Los pacientes con retinopatía diabética proliferativa pueden sufrir esta enfermedad de difícil tratamiento para el oftalmólogo, y que constituye una amenaza para la visión del paciente. Objetivo: revisar aspectos clínicos, patogenia, métodos para el diagnóstico y tratamiento terapéutico del glaucoma neovascular con vistas a prevenir o reducir la pérdida visual. Desarrollo: el glaucoma neovascular es una complicación de la diabetes mellitus y de otras enfermedades generales, que provoca una disminución importante de la visión, y en muchas ocasiones, ceguera. Las enfermedades oculares que con más frecuencia lo producen son la oclusión de la vena central de la retina, la retinopatía diabética proliferativa y el síndrome isquémico ocular, generando isquemia retiniana y coroidea con la consecuente formación de neovasos. Conclusiones: la educación al paciente diabético y el adecuado tratamiento terapéutico de la retinopatía diabética es importante para prevenir la aparición del glaucoma neovascular(AU)


Introduction: neovascular glaucoma is the type of secondary glaucoma common in diabetic patients; it is caused by the formation of fibrovascular membrane at the camerular angle as a result of angiogenic stimulus due to ocular ischemia-generating diseases. The proliferative diabetic retinopathy patients may suffer this difficult-to-treat disease that represents a threat to the vision of a patient. Objective: to review clinical aspects, pathogenenesis, diagnosis methods and treatment of the neovascular glaucoma with a view to preventing or reducing the vision loss. Development: neovascular glaucoma is a complication of diabetes mellitus and of other general diseases, which brings about significant reduction of vision and often blindness. The most frequent eye diseases responsible for this are central retinal vein occlusion, proliferative diabetic retinopathy and ocular ischemic syndrome, leading to retinal and choroid ischemia with resulting formation of neovessels. Conclusions: education aimed at diabetic patient and the adequate therapeutic treatment of the diabetic retinopathy is important to prevent the occurrence of neovascular glaucoma(AU)

ABSTRACT

ABSTRACT Clinical presentations associated with vitamin A deficiency persist in poor regions globally with the same clinical features as those described centuries ago. However, new forms of vitamin A deficiency affecting the eyes, which have become widespread, as a result of modern societal habits are of increasing concern. Ophthalmic conditions related to vitamin A deficiency require the combined attention of ophthalmologists, pediatricians, internists, dermatologists, and nutritionists due to their potential severity and the diversity of causes. As the eyes and their adnexa are particularly sensitive to vitamin A deficiency and excess, ocular disturbances are often early indicators of vitamin A imbalance. The present review describes the clinical manifestations of hypovitaminosis A with an emphasis on so-called modern dietary disorders and multidisciplinary treatment approaches. The present review also discusses the relationship between retinoic acid therapy and dry eye disease.


RESUMO As apresentações clínicas associadas à deficiência de vitamina A persistem em regiões pobres ao redor do mundo com os mesmos achados clínicos descritos há séculos. No entanto, novas formas de problemas causados pela vitamina A afetam os olhos, estão associados com os hábitos da sociedade moderna e tem causado preocupação. Eles exigem a atenção dos oftalmologistas, pediatras, internistas, dermatologistas e nutricionistas, devido à sua gravidade e diversidade de causas. Uma vez que os olhos e seus anexos são órgãos muito sensíveis à deficiência e excesso de vitamina A, manifestações oculares podem ser indicadores precoces do desequilíbrio de vitamina A. Essa revisão traz as manifestações clínicas de hipovitaminose A enfatizando os chamados distúrbios dietéticos modernos e formas de abordagem multidisciplinar. E também traz evidências sobre a relação entre a terapia com ácido retinóico e doença do olho seco.

ABSTRACT

RESUMO Objetivo: Determinar os fatores epidemiológicos e analisar as principais causas etiológicas dos pacientes atendidos com queixa de olho vermelho no setor de urgência e emergência de um hospital oftalmológico de ensino do estado de Minas Gerais. Métodos: Foi realizado um estudo de prevalência observacional, analítico com amostra não probabilística formado pelos pacientes que compareceram no setor de urgência da Fundação Hilton Rocha nos meses de janeiro a abril de 2014 (n=1140). Foram analisadas as seguintes variáveis: gênero, idade, raça, profissão, escolaridade, renda, meio de transporte, tempo decorrido entre o sintoma inicial e o primeiro atendimento, dia da semana, presença de baixa da acuidade visual e diagnóstico. Resultados: A amostra apresentou 390 pacientes com queixa de olho vermelho, 57,4% (n=224) eram do sexo feminino, a idade variou entre 3 e 97 anos, sendo a média de 43,7 anos. A maioria dos pacientes (87,6%, n=341) procurou o serviço em até 14 dias do início dos sintomas e apenas 75 indivíduos (19,4%) apresentavam baixa acuidade visual. As classes econômicas inferiores (classes D e E) são predominantes entre os atendidos. A principal causa da queixa de olho vermelho foi conjuntivite e blefaroconjuntivite infecciosas (32,6%, n=127). Conclusão: A conjuntivite infecciosa foi a morbidade de maior incidência. A Fundação Hilton Rocha desempenha um papel importante no atendimento à urgência oftalmológica da rede pública de Minas Gerais, sendo importante identificar as principais causas de atendimento e ampliar os estudos epidemiológicos e sociais, a fim de melhorar o acesso da população às urgências oftalmológicas e nos dar subsídios para campanhas de orientação, voltadas principalmente para as classes sociais menos favorecidas.


ABSTRACT Objective: Determining the epidemiological factors and analyzing the main etiological causes of the patients treated with red-eye complaint at the urgency and emergency sector of the ophthalmological hospital in the state of Minas Gerais. Methods: A prevalence observational analytical study was performed with a non-probabilistic sample formed by patients who visited the emergency room of the Fundação Hilton Rocha Hospital from january to april 2014 (n=1140). The following variables investigated were: gender, age, race, profession, education, income, means of transportation, time elapsed between the first symptom and the first visit, day of the week, low visual acuity symptom, diagnosis and treatment. Results: Out of the sample of 390 patients with red eye complaint, 57.4 % (n= 224) were female and the age ranged from 3 to 97, with an average of 43.7 years of age. The majority of patients, 87.6% (n= 341) sought the service up to 14 days after the onset of symptoms, only 75 individuals (19.4 %) had low visual acuity. The lower economic classes (classes D and E) are prevalent among patients. The main cause of red eye complain was conjunctivitis and infectious blepharoconjunctivitis 32.6% (n= 127). Conclusion: Infectious conjunctivitis was the morbidity with the highest incidence. The Fundação Hilton Rocha plays an important role in providing urgent ophthalmological care in the public health network in Minas Gerais. It is important to identify the most frequent causes of medical service for ocular diseases and expand the epidemiological and social studies in order to improve people’s access to ophthalmic emergencies and give us subsidies for guidance campaigns, focused mainly on the lower social classes.

ABSTRACT

OBJECTIVE: This study sought to describe and analyze ocular findings associated with nonocular surgery in patients who underwent general anesthesia. METHODS: The authors retrospectively collected a series of 39,431 surgeries using standardized data forms. RESULTS: Ocular findings were reported in 9 cases (2.3:10,000), which involved patients with a mean age of 58.9±19.5 years. These cases involved patients classified as ASA I (33%), ASA II (55%) or ASA III (11%). General anesthesia with propofol and remifentanil was used in 4 cases, balanced general anesthesia was used in 4 cases, and regional block was used in combination with balanced general anesthesia in one case. Five patients (55%) underwent surgery in the supine position, one patient (11%) underwent surgery in the lithotomy position, two patients (22%) underwent surgery in the prone position, and one patient (11%) underwent surgery in the lateral position. Ocular hyperemia was detected in most (77%) of the 9 cases with ocular findings; pain/burning of the eyes, visual impairment, eye discharge and photophobia were observed in 55%, 11%, 11% and 11%, respectively, of these 9 cases. No cases involved permanent ocular injury or vision loss. CONCLUSION: Ophthalmological findings after surgeries were uncommon, and most of the included patients were relatively healthy. Minor complications, such as dehydration or superficial ocular trauma, should be prevented by following systematic protocols that provide appropriate ocular occlusion with a lubricating ointment and protect the eye with an acrylic occluder. These procedures will refine the quality of anesthesia services and avoid discomfort among patients, surgeons and anesthesia staff. .

ABSTRACT

AbstractBACKGROUND:Peri-orbital dark circles are a cosmetic concern worldwide, and have been attributed to hyperpigmentation from allergy or atopic dermatitis, blood stasis, structural shadowing effects, and a thin epidermis/dermis under the eye. It is of interest to better understand lifestyle and demographic risk factors and the relative impact of melanin, blood and epidermal/dermal factors on the severity of Peri-orbital dark circles.OBJECTIVE:To compare by non-invasive imaging the impact of biological factors to a visual grading scale for Peri-orbital dark circles, and test the correlation of various demographic factors with Peri-orbital dark circles.METHODS:Subjects completed a lifestyle and health survey, and Peri-orbital dark circles severity was evaluated using standardized photographs. Hyperspectral image analysis was used to assess the contributions of melanin, blood volume, degree of blood oxygen saturation, and dermal scattering.RESULTS:Family history was the most significant risk factor for Peri-orbital dark circles. The average age of onset was 24 years, and earlier onset correlated with higher severity scores. Asthma was significantly associated with Peri-orbital dark circles scores, but self-reported allergy was not. In this study, sleep was not correlated with Peri-orbital dark circles scores. Hyperspectral imaging indicated that melanin was the dominant correlate for Peri-orbital dark circles severity, while oxygen saturation was secondary. The difference between under-eye and cheek measurements for ΔL*and ΔE* were the most significant instrumental parameters correlated with visual assessment of Peri-orbital dark circles severity.CONCLUSION:Although typically associated with lack of sleep, risk of Peri-orbital dark circles is primarily hereditary. The main factors contributing to the appearance of Peri-orbital dark circles are melanin and (deoxygenated) blood.

ABSTRACT

Introducción: La secuencia Moebius se caracteriza por el compromiso congénito de los nervios motor ocular externo y facial, y se puede asociar al compromiso de otros pares craneales y a otros defectos congénitos. Su etiología es multifactorial y no bien definida, actualmente la teoría más aceptada es la disrupción vascular durante el desarrollo del romboencéfalo. Su incidencia exacta se desconoce, pero impresiona estar en aumento y asociada a la exposición prenatal a teratógenos. Objetivos: Analizar las historias clínicas de 30 pacientes con secuencia Moebius y las características de su compromiso ocular. Materiales y métodos: Estudio retrospectivo, transversal, observacional y descriptivo. Se analizaron 30 historias clínicas de pacientes con secuencia Moebius atendidos por vez primera entre el mes de Julio de 1999 y Junio de 2012 por el servicio de Oftalmología del Hospital Garrahan. Resultados: Se estudiaron 30 pacientes 15 de sexo femenino y 15 de sexo masculino, dentro de los antecedentes maternos 7 madres refirieron ingesta de misoprostol y 4 tuvieron metrorragias durante el primer trimestre de embarazo. Todos los pacientes tuvieron compromiso del VII nervio; en 20 pacientes fue bilateral y simétrico; y en los restantes asimétrico. Todos los pacientes tuvieron compromiso del VI nervio bilateral, a algunos de los cuáles se les efectuó cirugía de estrabismo otros están en plan de cirugía y unos pocos no la requirieron por presentar fijación de ambos ojos en posición primaria de la mirada. Conclusión: la secuencia Moebius es una rara patología genética y congénita multifactorial y de compromiso multisistémico que ha visto incrementada su frecuencia desde el uso de ciertos fármacos teratógenos y que obliga a una intervención quirúrgica precoz de neuroortopedistas, oftalmólogos, cirujanos plásticos y control clínico multidisciplinario para brindarles a estos niños las mejores posibilidades de desarrollo funcional y estético reparador (AU)


Introduction: Moebius syndrome is characterized by congenital palsy of the external and facial oculomotpr nerves, and may be associated with involvement of other cranial nerves and congenital defects. The etiology is multifactorial and not well defined. Currently, the most widely accepted theory is a rhombencephalic maldevelopment. The true incidence of Moebius syndrome is unknown, but it seems to be increasing associated with prenatal exposure to teratogenic factors. Objectives: To analyze the clinical charts of 30 patients with Moebius syndrome assessing ocular involvement. Material and methods: A retrospective, cross-sectional, observational study. Thirty clinical charts of patients with Moebius syndrome that were first seen at the Department of Ophthalmology of Hospital Garrahan between July 1999 and June 2012 were assessed. Results: Of the 30 patients 15 were female and 15 male. Maternal history showed seven mothers that received misoprostol and four that had metrorrhagia in the first trimester of pregnancy. All patients had VII cranial nerve involvement; the involvement was bilateral and symmetric in 20 and asymmetric in the remaining patients. All patients had bilateral VI nerve involvement, some of whom underwent surgery for strabismus, others are on the list for surgery, and a few do not require surgery because of fixation of both eyes in primary gaze position. Conclusion: Moebius syndrome is a rare multifactorial genetic and congenital pathology with multisystemic involvement and increased incidence because of the use of teratogenic drugs requiring early surgical intervention by neuroorthopedic and plastic surgeons, and ophthalmologists, and a multidisciplinary follow-up to provide these children with the best possibilities for functional development and aesthetic repair (AU)

ABSTRACT

Objetivo: describir la Función de Sensibilidad al Contraste (FSC) en pacientes con miopía, astigmatismo miópico, hipermetropía y astigmatismo hipermetrópico. Diseño del estudio: serie de casos, descriptivo. Métodos: se incluyeron sujetos con miopía, astigmatismo miópico, hipermetropía y astigmatismo hipermetrópico, candidatos para cirugía refractiva y evaluados en la Unidad de Cirugía Refractiva de la Clínica de Oftalmología de Cali, con agudeza visual mejor corregida (AVMC) >=20/20, menores de 50 años de edad y sin antecedente de cirugía refractiva. La función sensibilidad al contraste se midió con el sistema OPTEC® 6500 (Stereo Optical Co, Inc., Chicago, USA) en frecuencias espaciales de 1.5, 3.0, 6.0, 12 y 18 ciclos/grado en condiciones fotópicas (85 cd/m2) y mesópicas (3 cd/m2). Se aplicaron las prueba no paramétrica de Wilcoxon y de Mann-Whitney para comparar diferencias entre la FSC entre los grupos de miopía/astigmatismo miópico e hipermetropía/astigmatismo hipermetrópico en las diferentes frecuencias espaciales. Resultados: se incluyeron 188 ojos de 95 sujetos con miopía y astigmatismo miópico (promedio de edad = 30,6 ± 7,6 años, 51% hombres) y 121 ojos de 64 sujetos con hipermetropía y astigmatismo hipermetrópico (promedio de edad = 43 ± 6,1 años, 62 % mujeres). La sensibilidad al contraste en los pacientes de ambos grupos fue mayor significativamente en condiciones fotópicas que en condiciones mesópicas, excepto en la frecuencia espacial de 3 ciclos/grado del grupo de miopía/astigmatismo miópico. Se encontró diferencia estadísticamente significativa del valor de la FSC entre los grupos de miopía/astigmatismo miópico e hipermetropía/astigmatismo hipermetrópico en condiciones fotópicas en casi todas las frecuencias espaciales, excepto en 3 ciclos/grado y en condiciones mesópicas en las frecuencias espaciales de 1.5, 3 y 6 ciclos/grado. Conclusiones: los valores de FSC son mayores en el grupo de pacientes con miopía y astigmatismo miópico que en los del grupo de hipermetropía y astigmatismo hipermetrópico. Estos valores podrían usarse como referencia en estos grupos de pacientes en nuestra población.


Purpose: to describe the contrast sensitivity function (CSF) in patients with myopia, hyperopia and astigmatism. Study design: descriptive case series study. Methods: subjects with myopia/myopic astigmatism and with hyperopia/hyperopic astigmatism looking for refractive surgery, and evaluated at the Unit of Refractive Surgery in the Clínica de Oftalmología de Cali were included. Their Best Spectacle Corrected Visual Acuity (BSCVA) was >=20/20, age less than 50 years and no previous refractive surgery. The CSF was measured using the OPTEC® 6500 (Stereo Optical Co, Inc, Chicago, USA) system for spatial frequencies 1.5, 3.0, 6.0, 12 and 18 cycles/degree in photopic (85 cd/m2) and mesopic (3 cd/m2) conditions. Statistical analysis was done using the Wilcoxon and Mann-Whitney tests for non-parametric samples, comparing the myopia/myopic astigmatism and the hyperopia /hyperopic astigmatism groups. Results: 188 eyes of 95 subjects with myopia/myopic astigmatism (age = 30,6 ± 7.6 years, 51% men) and 121 eyes of 64 subjects with hyperopia/hyperopic astigmatism (age = 43± 6.1 years, 62% women) were analyzed. The CSF was higher in both groups in photopic conditions except in 3 cycles per degree in myopia/myopic astigmatism group. Significant differences in the CSF were found between the two groups in photopic conditions excluding the 3 cycles per degree. In mesopic conditions diff erences were found for the spatial frequencies 1.5, 3 and 6 cycles per degree. Conclusions: The patients of the myopia/myopic astigmatism group had a contrast sensitivity function higher than those of hyperopia/hyperopic astigmatism group. These values could be used as reference for these patients in our population.
