Relationships between corneal biomechanics and the structural and functional parameters of glaucoma damage

Arq. bras. oftalmol; 83 (2), 2020
ABSTRACT Purpose: To investigate the relationships between (i) thickness of the retinal nerve fiber layer, optic nerve head topography, and visual field parameters and (ii) corneal biomechanical properties in normal controls and patients with ocular hypertension and primary open-angle glaucoma. Methods...

Reproducibility of retinal and choroidal measurements using swept-source optical coherence tomography in patients with Parkinson's disease

Arq. bras. oftalmol; 83 (1), 2020
ABSTRACT Purpose: To assess the reproducibility of retinal and choroidal measurements in the macular and peripapillary areas using swept-source optical coherence tomography in patients with Parkinson's disease. Methods: A total of 63 eyes of 63 patients with idiopathic Parkinson's disease were evaluate...

Autofluorescência em um caso de distrofia macular anular concêntrica benigna

Rev. bras. oftalmol; 78 (4), 2019
Resumo A distrofia macular anular concêntrica benigna (DMACB) é uma patologia retiniana rara e provavelmente subdiagnosticada em nosso meio, que se caracteriza por um defeito retiniano em bull's eye sem uso prévio de antimaláricos, associado à preservação relativa da acuidade visual. Devido à esc...

Association between Chagas disease and changes in the optic nerve and retinal nerve fiber layer

Arq. bras. oftalmol; 82 (3), 2019
ABSTRACT Purpose: To test the hypothesis that Chagas disease predisposes to optic nerve and retinal nerve fiber layer alterations. Methods: We conducted a cross-sectional study including 41 patients diagnosed with Chagas disease and 41 controls, paired by sex and age. The patients underwent ophthalmolo...

Objective evaluation of vision quality in pseudophakic patients with posterior capsular opacification using double-pass retinal imaging

Arq. bras. oftalmol; 82 (3), 2019
ABSTRACT Purpose: The purpose of this study was to objectively assess the optical vision quality of patients before and after Nd:YAG capsulotomy for posterior capsular opacification using a double-pass retinal imaging system. Methods: We retrospectively analyzed the data from 26 pseudophakic eyes with ...

Are the effects of hemodialysis on ocular parameters similar during and after a hemodialysis session?

Arq. bras. oftalmol; 80 (5), 2017
ABSTRACT Purpose: To evaluate the changes in several ocular parameters, including choroidal thickness, during and after hemodialysis. Methods: Twenty-seven eyes of 27 patients with chronic renal failure undergoing hemodialysis were included. The patients underwent an ophthalmic examination, including i...

Retinal function in patients with the neuronal ceroid lipofuscinosis phenotype

Arq. bras. oftalmol; 80 (4), 2017
ABSTRACT Purpose: To analyze the clinical features, visual acuity, and full-field electroretinogram (ERG) findings of 15 patients with the neuronal ceroid lipofuscinosis (NCL) phenotype and to establish the role of ERG testing in NCL diagnosis. Methods: The medical records of five patients with infanti...

Photoreceptor assessment using adaptive optics in resolved central serous chorioretinopathy

Arq. bras. oftalmol; 80 (3), 2017
ABSTRACT We present a case of a patient with resolved central serous chorioretinopathy (CSC) in the left eye with persistent mild visual alterations 4 years after the resolution of the disease. Left eye exam revealed a best corrected visual acuity of 20/25 and a slight change of macular pigmentation. Opt...

Evaluation of choroidal and retinal thickness measurements in adult hemodialysis patients using spectral-domain optical coherence tomography

Arq. bras. oftalmol; 79 (4), 2016
ABSTRACT Purpose: To assess the effect of hemodialysis on retinal and choroidal thicknesses using spectral-domain optical coherence tomography (SD-OCT). Methods: In this prospective interventional study, 25 hemodialysis patients (17 male, 8 female) were enrolled. All participants underwent high-speed, ...

Cognitive performance of primary open-angle glaucoma and normal-tension glaucoma patients

Arq. bras. oftalmol; 79 (2), 2016
ABSTRACT Purpose: To assess cognitive performance differences among primary open-angle glaucoma (POAG) patients, normal-tension glaucoma (NTG) patients, and healthy control (C) subjects. Methods: A total of 60 participants (20 POAG, 20 NTG, and 20 C subjects) were included in this study. A detailed oph...
