Aims: Optokinetic-based paradigms used to derive objective visual acuity suffer so far from low predictive power. Arguably, the contribution of the peripheral stimulation and the discrepancy between detection and discrimination threshold can bias the outcomes. In this respect, hi...

Aims: Long-term cortical reorganization after cortical damage can induce abnormal spatial relationship perception (spatial anisotropy) but there is also evidence of short-term, reversible cortical re-modulation even in the absence of cerebral damage: simulated hemianopic deprivat...

Background: Early diagnosis is the main requisite for rehabilitating children suspected to suffer from dyslexia, and self-reports may be as reliable as ordinary screenings, but far less expensive. Research shows that the visual function can be involved in the pathogenesis of dysl...

The damage to the visual field is the main outcome of glaucoma. Basically, there are two different approaches to establish the rate of the functional loss in this clinical condition: event-based analysis and trend-based analysis. The event-based analysis, that relies on the occur...

Research Article10.9734/or/2020/v13i130158
Aims: A computational model aimed to estimate the proportion of visual/motor deficits (first-order defects) and visual-motor abnormal integration (second-order defect) in dyslexic children is described. Study Design: Single-masked case-control study. Place and Duration of Study:...

Aims: To assess whether the spatial distortion underlying the so-called “thin man phenomenon” experienced by cortically impaired patients with homonymous defects depends on the cortical damage or on the scotoma itself. Study Design: Analysis of a representative case. Place and Du...
Aims: To investigate visuoperceptive abnormalities in adult dyslexics with the TETRA Analyzer™, and to compare the results with those obtained with normal adult readers. Study Design: Epidemiological study. Place and Duration of Study: Service of Neuro-Ophthalmology, University o...
Aims: To collect normative data in adult readers with the TETRA Analyzer™, a tool developed to detect the visuoperceptive alterations supposedly involved in dyslexia. Study Design: Epidemiological study. Place and Duration of Study: Service of Neuro-Ophthalmology, University of T...
In the last decades evidence has been collected that the depletion of the visual magnocellular population (a fast-conduction cellular system made of large ganglion neurons) plays a pathogenetical role in developmental dyslexia. Smaller size of the magnocells and reduction of thei...

Aims: To evaluate the effectiveness of visual training aimed at improving the visual function in dyslexic children suffering from increased crowding. Study Design: Single-masked crossover pilot study. Place and Duration of Study: University of Turin and the Gradenigo Hospital, De...
Aims: There is evidence that the deprivation of a sensory system at early developmental stage may lead to a functional change of the remaining one(s). Even if this process has been widely studied, results are still controversial. In particular, the auditory system might affect t...
Developmental dyslexia, one of the most common neuro-developmental disorders, is frequently under-diagnosed or diagnosed late. Despite there is consensus on the neurobiological and genetic basis and on the environmental influence, the multi-faceted aspects of dyslexia and the com...
