ABSTRACT
ABSTRACT A 37-year-old woman complained of headaches following bilateral visual loss in the past two years. She was obese and had undergone bariatric surgery three months earlier, followed by a considerable weight loss. Neuro-ophthalmic examination revealed a bilateral swollen optic disk. After a computerized analysis of the visual fields and magnetic resonance imaging of the brain and orbits, a diagnosis of idiopathic intracranial hypertension was made. At six months after the bariatric surgery, the patient reported no further headaches and exhibited better findings on computerized analysis of visual fields. However, fundus examination revealed persistent mild papilledema in both eyes. Ocular B-scan ultrasonography showed bilateral optic disk drusen. This report highlights the coexistence of true papilledema and pseudopapilledema due to optic disk drusen, following remission of idiopathic intracranial hypertension after a bariatric surgery.
RESUMO Uma mulher de 37 anos queixou-se de cefaleia após perda visual bilateral nos últimos dois anos. Apresentava história de obesidade e havia sido submetida à cirurgia bariátrica três meses antes, seguida de considerável perda de peso. O exame neuro-oftálmico revelou um disco óptico inchado bilateral. Após uma análise computadorizada dos campos visuais e ressonância magnética do crânio e órbitas, foi feito um diagnóstico de hiper tensão intracraniana idiopática. Após seis meses da cirurgia bariátrica, a paciente não relatou mais cefaleia e foram descobertas melhoras na análise computadorizada dos campos visuais. No entanto, o exame de fundo de olho revelou papiledema leve persistente em ambos os olhos. A ultrassonografia ocular B-scan mostrou drusas do disco óptico bilateralmente. Este relato destaca a coexistência de papiledema verdadeiro e pseudopapiledema devido à drusa de disco óptico após remissão da hipertensão intracraniana idiopática após uma cirurgia bariátrica.

Neuromyelitis optica antibody (or aquaporin-4 antibody) is a well established serum marker associated to high-risk neuromyelitis optica syndrome that presents as an inflammatory demyelinating disease characterized by the occurrence of bilateral and simultaneous optic neuritis without complete visual recovery or it occurs as an isolated episode of transverse myelitis accompanied by longitudinally extensive spinal cord lesions. On the other hand, Leber hereditary optic neuropathy is a primarily hereditary disorder that affects all tissues of the body and its clinical presentation is tissue-specific for the optic nerve and, eventually, it might reach the spinal cord. Overlapping clinical features of neuromyelitis optica and Leber hereditary optic neuropathy may suggest common target organ diseases. The case report described herein emphasizes the coexistence of serum markers of both diseases, and suggests that further investigation of this challenging clinical presentation is warranted to confirm or rule out this association.

Neuromyelitis optica antibody (or aquaporin-4 antibody) is a well stablished serum marker associated to high-risk neuromyelitis optica syndrome that presents as an inflammatory demyelinating disease characterized by the occurrence of bilateral and simultaneous optic neuritis without complete visual recovery or it occurs as an isolated episode of transverse myelitis accompanied by longitudinally extensive spinal cord lesions.

Anticorpo da neuromielite óptica (ou anticorpo aquaporina-4) é um marcador sorológico bem estabelecido associado à síndrome de alto risco para neuromielite óptica, doença inflamatória desmielinizante, caracterizada por ocorrência bilateral, simultânea de neurite óptica ou por episódio isolado de mielite transversa com achado de lesões espinais longitudinais extensas. Por outro lado, a neuropatia óptica hereditária de Leber é uma doença primariamente hereditária que afeta todos os tecidos do corpo e sua apresentação clínica envolve o nervo óptico e, eventualmente, a medula espinal. Aspectos clínicos comuns sugerem que neuromielite óptica e neuropatia óptica hereditária de Leber possam atingir os mesmos órgãos. O caso descrito enfatiza a coexistência de marcadores sorológicos das duas doenças e sugere a necessidade de investigação futura desta apresentação clínica atípica para confirmar ou não esta associação.

A 70-year-old man presented complaining of lid and facial drooping and facial numbness, which progressed over several months. Magnetic resonance imaging of the head showed an enlarged right cavernous sinus. His past medical history was remarkable to squamous cell carcinoma of the face. The patient underwent a craniotomy with biopsy of the cavernous sinus that confirmed malignancy. High index of suspicion in a patient that presents facial drooping and/or numbness should alert ophthalmologists about the occurrence of perineural spread of a previous malignant lesion of the skin.

PURPOSE: To develop and investigate the reliability and validity of a Brazilian version of the 25-Item National Eye Institute Visual Function Questionnaire. METHODS: A Brazilian version of the questionnaire was developed and applied to patients with chronic eye diseases and healthy controls. Reliability was assessed by Cronbach's alpha coefficient, intraclass correlation coefficient and interrater reliability coefficient. Participants were submitted to the Medical Outcomes Study Short Form-36 Questionnaire. Validity was estimated by the correlation between the questionnaires and among the 12 subscales of the questionnaire, subscales scores and visual acuity, patients' and controls' subscales scores, and the factor analysis. Responsiveness of the questionnaire was assessed in a group of patients before and following cataract surgery. RESULTS: Cronbach's alpha, intraclass correlation and interrater reliability coefficients were highly significant. Validity was well established in all tests. In patients who underwent cataract surgery, a better vision-related quality of life was observed following surgery. CONCLUSION: The Brazilian version of the 25-Item National Eye Institute Visual Function Questionnaire has valid and reliable psychometric properties and can be applied to vision-related quality of life research.

OBJETIVO: Desenvolver e investigar a confiabilidade e a validade da versão brasileira do Questionário de Função Visual de 25 Itens do National Eye Institute. MÉTODOS: A versão brasileira do questionário foi desenvolvida e aplicada em pacientes com doenças oculares crônicas e controles sadios. A confiabilidade foi calculada pelo coeficiente alfa de Cronbach de correlação intraclasse e de confiabilidade entre examinadores. Foi usado o questionário "The Medical Outcomes Study Short Form-36". A validade foi calculada pela correlação entre as escalas dos questionários e entre as 12 subescalas do questionário, a pontuação das subescalas e a acuidade visual, a pontuação das subescalas de pacientes e controles e a análise fatorial. A validação do questionário foi calculada em grupo de pacientes antes e após cirurgia de catarata. RESULTADOS: O coeficiente de alfa de Cronbach, de correlação intraclasse e de variação entre entrevistadores, e os testes de validade da versão brasileira foram significantes. A responsividade foi confirmada pela melhora na qualidade de vida visual no grupo submetido à cirurgia de catarata. CONCLUSÃO: A versão brasileira do Questionário de Função Visual de 25 Itens apresenta propriedades psicométricas válidas e confiáveis e pode ser aplicado em pesquisa de qualidade de vida visual.
