ABSTRACT
PURPOSE: to describe a clinical case of ocular sarcoidosis in a patient with Autoimmune Polyglandular Syndrome Type 2 (APS-2). METHODS: an 86-year-old female diagnosed with APS-2 was referred to our uveitis department with rapid visual loss in her left eye during a 3-month period. Her best-corrected visual acuity (BCVA) was counting fingers in her left eye (OS) and 20/40 in her right eye (OD). Slit-lamp biomicroscopy was unremarkable OD but revealed granulomatous keratic precipitates OS. Fundoscopy revealed bilateral optic disc oedema and +2 and 4+ vitritis (SUN classification) in her OD and OS, respectively. RESULTS: the patient underwent chest X-Ray which revealed bilateral hilar lymphadenopathy and fibrosis. On high-resolution computed tomography of the lungs, ground-glass opacities were visible, and a diagnosis of ocular sarcoidosis was presumed. After exclusion of infectious diseases, the patient was treated with methotrexate and oral corticosteroids and there was substantial improvement of the optic nerve oedema and vitritis. At the most recent visit, 2 years later, OS BCVA was 20/50. CONCLUSION: There may be an association between ocular sarcoidosis and APS or other autoimmune disorders.
ABSTRACT
OBJECTIVE: Understand the behavior, functional repercussion and relationship with epidemiological factors of asteroid hyalosis (AH) and retrospective observational case series. METHODS: Fifty-eight patients diagnosed with AH (24 women and 34 men) were studied. All patients were submitted to a thorough ophthalmological examination. RESULTS: We observed a statistical association between the presence of AH and male sex (p=0,042). An increase in prevalence of this pathology was observed with increasing age. We determined an odds ration of 5,24 of a patient over 50 years old having AH, when compared to patients bellow this threshold. Eighty-six percent of patients had unilateral vitreous deposits. We measured a lower IOP in the affected eye, with the difference being in average 2,68 ± 1,45 mmHg (p=0,037). We observed no statistical association between AH and age related macular degeneration, diabetes or glaucoma. Five eyes were submitted to facoemulsification combined with pars plana vitrectomy with an average gain of 7 lines (Snellen) in visual acuity (p=0,03). CONCLUSION: In our sample a clear association between AH, ageing and male sex was observed. The majority of patients had unilateral vitreous deposits. Vitrectomy in association with facoemulsification is a safe and effective intervention in this group of patients.
OBJETIVO: Compreender o comportamento dos asteroides hialoides, sua repercussão funcional em relação aos fatores epidemiológicos,de modo retrospectivo e observacional de casos clínicos. MÉTODOS: Cinquenta e oito doentes com diagnóstico de asteroides hialoides (24 mulheres e 34 homens) foram estudados. Todos os doentes foram submetidos a exame oftalmológico completo. RESULTADOS: Observamos uma associação estatística entre a presença de asteroides hialoides e o sexo masculino (p=0,042). Verificamos um aumento de prevalência desta patologia com o aumento da idade sendo o risco relativo após os 50 anos de 6,25 face aos doentes abaixo desta idade. Oitenta e seis por cento dos doentes estudados apresentavam depósitos unilaterais. Não observamos associação estatística entre a presença de asteroides hialoides e a degeneração macular ligada à idade, diabetes mellitus ou glaucoma. Em 5 dos olhos estudados avaliamos o resultado funcional de cirurgia de facoemulsificação associada à vitrectomia via pars plana e observamos um ganho médio de 7 linhas de acuidade visual de Snellen (p=0,03) pós-cirurgia. CONCLUSÃO: A amostra apresenta uma clara associação entre o envelhecimento e sexo masculino e a incidência de asteroides hialoides. Na maioria dos doentes estudados os depósitos foram unilaterais. A vitrectomia via pars plana, associada à facoemulsificação é uma terapêutica segura e eficaz neste grupo de doentes.
