Coexistence of Straatsma syndrome without macular extension and abnormal ellipsoid zone

Rev. bras. oftalmol; 81 (), 2022
ABSTRACT Myelinated retinal nerve fibers are rare congenital anomalies that appear as gray-white patches. They may be present in a syndrome characterized by ipsilateral myelinated retinal nerve fibers, myopia and amblyopia. The author reported an ellipsoid zone defect on spectral domain optical coherence...

Identifying and understanding optical coherence tomography artifacts that may be confused with glaucoma

Rev. bras. oftalmol; 81 (), 2022
ABSTRACT Optical coherence tomography is often used for detection of glaucoma as well as to monitor progression. This paper reviews the most common types of artifacts on the optical coherence tomography report that may be confused with glaucomatous damage. We mainly focus on anatomy-related artifacts in ...

SD-OCT assessment and visual field changes 1 year or more after a single episode of unilateral acute primary angle closure

Rev. bras. oftalmol; 81 (), 2022
ABSTRACT Objective: To evaluate structural and visual field (VF) changes after ≥1 year of a single acute primary angle closure (APAC) attack using spectral-domain optical coherence tomography (SD-OCT) and standard automated perimetry (SAP). Methods: Patients with a single unilateral APAC crisis a...

Evaluation of choroidal thickness and retinal nerve fiber layer thickness in patients with unilateral amblyopia: a prospective study

Rev. bras. oftalmol; 80 (2), 2021
ABSTRACT Purpose: to compare the Subfoveal choroidal thickness (SFCT) and Retinal Nerve Fiber Layer Thickness (RNFL) of amblyopic and normal fellow eyes. Design: Prospective, cross-sectional, observational case series. Methods: Forty patients age 12 to 41 years (mean 23.73 ± 6.42) with unilateral ambl...

Assessment of intraocular pressure, macular thickness, retinal nerve fiber layer, and ganglion cell layer thicknesses: ocular parameters and optical coherence tomography findings in attention-deficit/hyperactivity disorder

Objective: To compare intraocular pressure (IOP) and macular, retinal nerve fiber layer (RNFL), and ganglion cell layer (GCL) thicknesses in treatment-naive children with attention-deficit/hyperactivity disorder (ADHD), children with ADHD on regular methylphenidate (MPH) treatment for at least 3 months, ...

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...

O artigo visa relatar ocaso de um paciente diagnosticado c...

Optical coherence tomography findings in bipolar disorder: a preliminary receiver operating characteristic analysis on ganglion cell layer volume for diagnosis

Abstract Background Optical coherence tomography (OCT) has been recently used to investigate neuropsychiatric disorders. Objective The aim of this study was to compare the retinal nerve fiber layer thickness (RNFLT) and the ganglion cell layer (GCL) volume in patients with type 1 bipolar disorder (BP...

Relationship between erythrocyte sedimentation rate and choroidal and retinal thickness in Behçet's disease

Arq. bras. oftalmol; 82 (4), 2019
ABSTRACT Purpose: To compare retinal and choroidal thickness in patients with Behçet's disease with and without ocular involvement as well as to evaluate the correlation between erythrocyte sedimentation rate and choroidal thickness among patients with Behçet's disease. Methods: This was a prospectiv...
