RÉSUMÉ

OBJECTIVES@#Dysthyroid optic neuropathy (DON) is a class of diseases that makes seriously endanger to the vision of patients with thyroid-associated ophthalmopathy. This study aims to observe the visual function changes in patients with DON, and to evaluate the diagnostic value of indicators diagnosing DON.@*METHODS@#A retrospective study was conducted on 98 eyes of 49 patients with dysthyroid optic neuropathy (DON) who were treated in Xiangya Hospital of Central South University from January 2017 to December 2019. All patients were received the examination of best corrected visual acuity (BCVA), Humphrey visual field, visual evoked potential (VEP), and contrast sensitivity. Ninety-eight eyes were divided into a DON group (45 eyes) and a non-DON group (53 eyes). T-test was used to compare the related indicators between the 2 groups. The sensitivity and specificity of each indicator were analyzed by receiver operating characteristic (ROC) curve.@*RESULTS@#The BCVA and visual field index (VFI) of the DON group were significantly lower than those of the non-DON group (all P<0.05). The mean deviation (MD) and pattern standard deviation (PSD) of the DON group were significantly higher than those of the non-DON group (all P<0.05). The low frequency contrast sensitivity (CSL), medium frequency contrast sensitivity (CSM), and high frequency contrast sensitivity (CSH) of the DON group were significantly lower than those of the non-DON group (all P<0.05), with CSH being particularly prominent. Compared with the non-DON group, at spatial frequencies of 15°, 30°, and 60°, the amplitude of N135 wave was significantly reduced, and the latency of N75 wave, P100 wave, and N135 wave was significantly prolonged in the DON group (all P<0.05); at spatial frequencies of 15° and 30°, the amplitude of P100 wave was significantly reduced in the DON group (P<0.05). The ROC curve analysis results showed that the area under the curve (AUC) of VFI, CSL, CSM, CSH and 15° P100 amplitude diagnosing DON were 0.812, 0.841, 0.880, 0.784, and 0.791, respectively, with CSM possessing the highest sensitivity and specificity.@*CONCLUSIONS@#The visual function of patients with DON is decreased. VFI, contrast sensitivity of low, medium, and high frequency, and 15° P100 wave amplitude might be effective indicators for early diagnosis of DON.

RÉSUMÉ

OBJETIVO: Avaliar 5 olhos com descolamento seroso da mácula devido à fosseta de disco óptico que foram submetidos à vitrectomia via pars plana e seguidos por pelo menos 7 anos. MÉTODOS: Os pacientes foram submetidos à vitrectomia via pars plana, remoção da membrana hialoide posterior, injeção de soro autólogo e troca fluido-gasosa, sem aplicação de fotocoagulação a laser, e foram testados quanto à acuidade visual, tela de Amsler, retinografia e, recentemente, retinografia com autofluorescência e OCT de alta resolução. RESULTADOS: Todos os 5 olhos operados tiveram significativa melhora da visão após o procedimento cirúrgico, mantendo boa visão durante todo período de acompanhamento. A acuidade visual pré-operatoria média foi de 20/400 enquanto a acuidade visual final foi de 20/27 com um tempo médio de seguimento de 13,6 anos. Não foram observadas recorrências do descolamento seroso da mácula e os exames de OCT mostraram a retina perfeitamente aplicada até a margem da fosseta de disco óptico. CONCLUSÃO: Descolamentos serosos da mácula causados por fosseta de disco óptico são adequadamente tratados com vitrectomia via pars plana e troca fluido-gasosa, sem a necessidade de fotocoagulação da retina, mantendo excelente acuidade visual por vários anos após o procedimento, sem o aparecimento de recorrências.


PURPOSE: To evaluate 5 patients with serous macular detachment due to optic disc pit that were submitted to pars plana vitrectomy and were followed for at least 7 years. METHODS: Patients were submitted to pars plana vitrectomy, posterior hyaloid removal, autologous serum injection and gas-fluid exchange, without laser photocoagulation, and were evaluated pre and post-operatively with visual acuity and Amsler grid testing, retinography, and recently, with autofluorescence imaging and high resolution OCT. RESULTS: All 5 eyes improved visual acuity significantly following the surgical procedure maintaining good vision throughout the follow-up period. Mean pre-operative visual acuity was 20/400 and final visual acuity was 20/27 with a mean follow-up time of 13.6 years. No recurrences of serous detachments were observed. OCT examinations demonstrated an attached retina up to the margin of the pit. CONCLUSION: Serous macular detachments due to optic disc pits were adequately treated with pars plana vitrectomy and gas fluid exchange, without the need for laser photocoagulation, maintaining excellent visual results for a long period of time.

RÉSUMÉ

PURPOSE: To investigate the clinical manifestations and diagnoses of optic disc swelling. METHODS: The medical records of 49 patients who experienced optic disc swelling between March 2008 and June 2009 were retrospectively reviewed. The characteristics of non-arteritic anterior ischemic optic neuropathy (NA-AION) and optic neuritis (ON), which showed optic disc swelling most commonly, were compared. RESULTS: NA-AION was the most common disorder (34.7%) that presented with optic disc swelling. ON was identified in 15 patients (30.6%). Seven out of 49 patients (14.3%) had intracranially associated diseases, such as papilledema and compressive optic neuropathy. Pseudopapilledema was noted in four patients (8.2%). Other diseases (e.g., papillophlebitis, neuroretinitis, and diabetic papillopathy) were seen in six patients (12.2%). Ocular pain was observed more commonly in patients with ON (p = 0.001). Patients with ON expected a better visual prognosis than patients with NA-AION (0.12 +/- 0.32 vs. 0.49 +/- 0.35, p = 0.001). CONCLUSIONS: NA-AION and ON should be considered in the differential diagnosis when patients with optic disc swelling present to the neuro-ophthalmology clinic. Detailed history taking and supportive examinations, such as visual field, color-vision and imaging tests, should also be performed as indicated. Regular follow-up of such exams is necessary for the differential diagnosis of these diseases.

RÉSUMÉ

We describe three patients with bilateral, presumed human immunodeficiency virus (HIV)-induced optic neuropathy. The above diagnosis was made by exclusion of infectious agents and neoplasms by detailed clinical and laboratory investigations. All patients had decreased visual acuity, pale optic discs and constriction of visual fields. Improvement was documented in all three patients for visual acuity and in one patient for visual fields following treatment with highly active antiretroviral therapy (HAART). Optic neuropathy in HIV-positive patients does not necessarily carry a poor prognosis even when a treatable cause is not found. This article emphasizes the effectiveness of HAART in presumed HIV-induced optic neuropathy.

RÉSUMÉ

En la presente exposición se narra vívidamente, una experiencia personal obtenida durante un viaje a Cuba en mayo de 1993. Durante una semana, formamos parte de una misión multidisciplinaria de expertos enviados por la OMS/OPS para atender un urgente llamado de ayuda de las autoridades de la isla. Se trataba de una severa epidemia de ceguera asociada a otros síntomas neurológicos, que llegó afectar unas cincuenta mil personas, por lo que se consideró "una nueva enfermedad", e inicialmente se dió en llamar "neuritis óptica" y posteriormente redenominada, "neupatía óptica cubana". La situación social prevalente, los factores predisponentes, la situación política agravante, las diversas causas invocadas y descartadas durante los primeros 2 años de su irrupción , la presencia de una etiología viral y el arribo final a un consenso, son detalladamente narradas. El hambre y la miseria fueron la razón etiológica última. Antecedentes de epidemias similares, de origen nutricional casencial, se encontraron a menudo en la literatura internacional destacando la evidencia recogida durante la Segunda Guerra Mundial en campos de concentración japoneses ubicados en zonas tropicales. En la segunda parte de la exposición se discutirán las características nutricionales, clínicas, neurológicas y neuro-oftalmológicas de la "neuropatía óptica cubana"

RÉSUMÉ

Foi realizado o estudo retrospectivo dos prontuários de 155 pacientes encaminhados para avaliaçäo neuro-oftalmológica, com o objetivo de identificar causas freqüentes de transtornos neuro-oftalmológicos, visando facilitar o diagnóstico diferencial, em serviços de atendimento primário. Foram obtidos dados referentes a hipótese diagnóstica final, doenças associadas e hábitos pessoais. A hipertensäo arterial sistêmica foi o antecedente mórbido pessoal mais freqüente. O etilismo foi o principal hábito pessoal. As principais causas de transtornos neuro-oftalmológicos foram: neuropatia óptica isquêmica näo-arterítica, neuropatia tóxico-carencial por alcoolismo, retinopatia associada à doença sistêmica e/ou simulando doença do nervo óptico, traumatismo crânio-encefálico, alteraçöes decorrentes de tumores cerebrais e anomalias congênitas. Várias causas freqüentes de distúrbios neuro-oftalmológicos podem ser identificadas mediante exame oftalmológico cuidadoso e exames complementares de fácil acesso e custo relativamente baixo.
