Optical coherence tomography (OCT) is a rapid non-contact method that allows in vivo imaging of the retina, optic nerve head and retinal nerve fibre layer (RNFL). Since its introduction in Ophthalmology approximately a decade ago, the use of this technology has disseminated into the clinical practice. OCT has proven to be a useful ancillary tool for(More)
AIM To evaluate the choroidal thickness (CT) in patients with long-standing Vogt-Koyanagi-Harada (VKH) disease using enhanced depth imaging optical coherence tomography (EDI-OCT). METHODS A prospective case-control study developed at a tertiary centre at São Paulo, Brazil. EDI-OCT images were obtained in 16 patients (30 eyes) with VKH disease who had had(More)
PURPOSE To analyse the rate of clinical recurrences in Brazilian patients with Vogt-Koyanagi-Harada (VKH) disease after early high-dose corticosteroid treatment. METHODS Retrospective study including patients treated with early high-dose corticosteroids (prednisone, 1-1.5 mg/kg/day, or 3-day 1 g methylprednisolone pulsetherapy) within 1 month from disease(More)
BACKGROUND To investigate indocyanine green angiography (ICGA) findings in patients with long-standing Vogt-Koyanagi-Harada (VKH) disease and their correlation with disease activity on clinical examination as well as with systemic corticosteroid therapy. METHODS Twenty-eight patients (51 eyes) with long-standing (≥6 months from disease onset) VKH disease(More)
Vogt-Koyanagi-Harada (VKH) disease is a systemic autoimmune disorder that affects pigmented tissues of the body, with its most dire manifestations affecting the eyes. This review focuses on the diagnostic criteria of VKH disease, including some information on history, epidemiology, appropriate clinical and classification criteria, etiopathogenesis,(More)
PURPOSE To assess the prevalence of glaucoma in a South Brazilian population. METHODS Subjects older than 40 years underwent a screening examination that included a medical interview, slit lamp examination, tonometry, and fundoscopy. Those with suspected glaucoma (based on optic disc appearance and/or intraocular pressure) underwent a comprehensive(More)
PURPOSE Nonpupil block mechanisms and appositional angle closure after laser iridotomy (LI) have been reported as common findings in Asians. We evaluated the presence of these findings in a cohort of Brazilian patients using ultrasound biomicroscopy (UBM). METHODS This observational case-control study included 22 open angle eyes and 31 eyes with(More)
BACKGROUND Detection of choroidal inflammation in Vogt-Koyanagi-Harada (VKH) disease is still a challenge. Progression to sunset glow fundus has been observed despite apparent good clinical control of inflammation. Indocyanine green angiography (ICGA) permits choroid inflammation detection, though it is invasive, time consuming, and costly. The purpose of(More)
Vogt-Koyanagi-Harada disease (VKHD) is a rare granulomatous inflammatory disease that affects pigmented structures, such as eye, inner ear, meninges, skin and hair. This disease is mainly a Th1 lymphocyte mediated aggression to melanocytes after a viral trigger in the presence of HLA-DRB1*0405 allele. The absence of ocular trauma or previous intraocular(More)
Purpose: To evaluate the efficacy and tolerance of mycophenolate mofetil (MMF) for the treatment of noninfectious uveitis using the methods advocated by the Standardization of Uveitis Nomenclature (SUN) Working Group and to compare this with other studies of immunosuppression in ocular inflammation. Methods: Retrospective case series. Patients with(More)
