Abstract Objective: To evaluate the choroidal thickness (CT) in healthy Brazilian subjects using spectral-domain optical coherence tomography (SD-OCT) and to compare with choroidal thickness measured in Brazilian patients with diabetic macular edema (DME), neovascular age-related macular degeneration (AMD) and high myopia. Methods: A retrospective analysis of spectral domain optical coherence tomography (SD-OCT) images of 181 Brazilian subjects. A total of 74 eyes were included in the normal control group, 50 eyes in the nvAMD group, 44 eyes in the DME […]

Abstract The purpose is to report the management of multiple retinal epithelial detachments (PEDs) in a 50-year-old male with bilateral PEDs not associated with chorioretinal or systemic pathologies after a complete study. Idiopathic multiple PEDs could be a variation of central serous chorioretinopathy, but other causes as well as other pathological conditions which could produce similar images, are required to be ruled out.

Objetivos: Comparar o efeito do ranibizumabe intravítreo (0,3mg) e triacmicinolona (4mg) em diferentes parâmetros do domínio espectral da OCT e sua relação com a acuidade visual de pacientes com edema macular diabético. Métodos: Este estudo foi concebido como um estudo prospectivo randomizado. Os pacientes foram divididos aleatoriamente em 2 grupos que receberam Ranibizumab Pro rata intravitreal (0,3mg) ou acetonido de Triamicinolona (4mg), a quem foi realizada a Spectral Domain OCT, bem como a melhor acuidade visual de Log MAR corrigida. […]

Objective: The aim of this study is to examine the effect of Nd: YAG laser capsulotomy on refraction, central macular thickness (CMT) and retinal nerve fiber layer (RNFL) thickness. Methods: 42 eyes of 42 patients who treated with Nd:YAG laser capsulotomy were included in thisprospective study. Spherical equivalent (SE), cyclindrical power refraction, CMT and RNFL thickness were evaluated preoperatively and at postoperative first day, first week and postoperative first month. Results: Spherical equivalent values and central macular thickness values did […]

Objetivo: O objetivo deste estudo é examinar o efeito da capsulotomia de laser Nd: YAG na refração, espessura macular central (CMT) e espessura da camada de fibra nervosa retiniana (RNFL). Métodos: 42 olhos de 42 pacientes que trataram com capsulotomia laser Nd: YAG foram incluídos neste estudo prospectivo. O equivalente esférico (SE), a refração de potência cíclica, a espessura CMT e RNFL foram avaliados pré-operatório e no primeiro dia pós-operatório, primeira semana e primeiro mês pós-operatório. Resultados: valores equivalentes esféricos […]

The authors make an update of pachychoroid in a group of the choroidal-retinal diseases that choroidal thickening is an usualenhanced depth image – optic coherence tomography (EDI-OCT) finding like as central serous chorioretinopathy, pachychoroid neovasculopathy, polipoidal choroidal vasculopathy and pachychoroid pigment epitheliopathy.

Os autores fazem uma atualização da presença do espessamento de coroide, um achado de tomografia de coerência óptica com imagem de profundidade melhorada (EDI-OCT) empatologias retino-coroidianas como coroido-retinopatia central serosa, espessamento de coroide com neovascularização, vasculopatiacoroidianapolipoidal e espessamento de coróide com epiteliopatia.

Acute zonal occult outer retinopathy (AZOOR) is a rare disease characterized by an acute damage of one or more external retinal zones leading to the visual field or the visual acuity impairment associated with small or no changes in the fundus examination.The main clinical symptoms are scotomas and the sudden onset of photopsias. Abnormal findings on electroretinography and visual field defects are critical for the diagnosis. Central vision is usually preserved and the stabilization occurs in six months in most […]
