Alzheimer's disease (AD) is the leading cause of dementia worldwide, but its pathophysiological phenomena are not fully elucidated. Many neurophysiological markers have been suggested to identify early cognitive impairments AD. However, diagnosis this remains a challenge for specialists. In present cross-sectional study, our objective was evaluate manifestations and mechanisms underlying visual-spatial deficits at stages AD.We combined behavioral, electroencephalography (EEG), eye movement...
Retinoscopy is one of the most effective objective techniques for evaluating refractive status, especially in non-cooperative patients. However, it presents a slow learning curve that often leads to student frustration. With current Covid-19 pandemic and need social isolation, clinical education based on simulation has become more relevant. Therefore, we implemented retinoscopy laboratories protocols reduce stress time.We conducted study evaluate using new training protocol proposal. One...
Amblyopia is the interocular visual acuity difference of two lines or more with best correction in both eyes. It treated ocular occlusion therapy, but its success depends on neuroplasticity, and thus effective children not adults. Transcranial Direct Current Stimulation (tDCS) suggested to increase neuroplasticity.To determine if combined intervention bilateral tDCS improves function adults amblyopia.A double-blind randomized, controlled pilot trial was conducted 10 volunteers amblyopia....
Abstract Amblyopia is the interocular visual acuity difference of two lines or more with best correction in both eyes. Ocular occlusion therapy depends on neuroplasticity, and thus effective children but not adult later diagnoses. Transcranial Direct Current Stimulation (tDCS) suggested to increase neuroplasticity. To determine if combined bilateral tDCS ocular improves function adults amblyopia, we conducted a double blind randomized, controlled pilot trial volunteers amblyopia...
Abstract Background Retinoscopy is one of the most effective objective techniques for evaluating refractive status, especially in non-cooperative patients. However, it presents a slow learning curve that often leads to student frustration. With current Covid-19 pandemic and need social isolation, clinical education based on simulation has become more relevant.

Abstract Background Many neurophysiological markers such as neuronal oscillations, cortical synchronization and long-range coupling have been suggested to permit the identification of early cognitive impairments in Alzheimer's disease (AD). However, it is still unclear whether alterations Functional Connectivity (FC) constitute part mechanisms initial stages AD. Methods Eighteen participants (69-88 years old), classified AD matching healthy controls, were evaluated while performing a virtual...
Abstract Glaucoma is a multifactorial neurodegenerative disease of the optic nerve currently considered severe health problem because its high prevalence, being primary cause irreversible blindness worldwide. The most common type corresponds to Primary Open-Angle (POAG). produces, among other alterations, progressive loss Retinal Ganglion Cells (RGC) and axons, key generate action potential that reaches visual cortex create image. It indicates Visual Field (VF) whose main feature be...
