Motion extrapolation into the blind spot: Research report [PDF]

, 2008
The flash-lag effect, in which a moving object is perceived ahead of a colocalized flash, has led to keen empirical and theoretical debates. To test the proposal that a predictive mechanism overcomes neural delays in vision by shifting objects spatially,

Multi-line Adaptive Perimetry (MAP): A New Procedure for Quantifying Visual Field Integrity for Rapid Assessment of Macular Diseases. [PDF]

, 2018
PurposeIn order to monitor visual defects associated with macular degeneration (MD), we present a new psychophysical assessment called multiline adaptive perimetry (MAP) that measures visual field integrity by simultaneously estimating regions associated

Visual function improvement using photocromic and selective blue-violet light filtering spectacle lenses in patients affected by retinal diseases [PDF]

, 2017
Background To evaluate functional visual parameters using photocromic and selective blue-violet light filtering spectacle lenses in patients affected by central or peripheral scotoma due to retinal diseases. Sixty patients were enrolled in this study:

Genetic epilepsies with myoclonic seizures: Mechanisms and syndromes

Epilepsia Open, EarlyView.
Abstract Genetic epilepsy with myoclonic seizures encompasses a heterogeneous spectrum of conditions, ranging from benign and self‐limiting forms to severe, progressive disorders. While their causes are diverse, a significant proportion stems from genetic abnormalities.

The Sound of Scotoma: Audio Space Representation Reorganization in Individuals With Macular Degeneration

Frontiers in Integrative Neuroscience, 2019
Blindness is an ideal condition to study the role of visual input on the development of spatial representation, as studies have shown how audio space representation reorganizes in blindness. However, how spatial reorganization works is still unclear.

The effect of magnification and contrast on reading performance in different types of simulated low vision [PDF]

, 2017
Low vision therapy, such as magnifiers or contrast enhancement, is widely used. Scientific evidence proving its efficacy is scarce however. The objective of this study was to investigate whether the benefits of magnification and contrast enhancement ...

Mesopic microperimetry in Stargardt disease: Application and reliability

Acta Ophthalmologica, EarlyView.
Abstract Purpose Mesopic microperimetry (mMP) is a promising functional endpoint in clinical trials for Stargardt disease type 1 (STGD1). This study evaluated the test–retest variability of mMP and influencing factors, which is essential for ensuring reliability in future STGD1 trials.

Visual responses of neurons in the middle temporal area of new World Monkeys after lesions of striate cortex [PDF]

, 2000
In primates, lesions of striate cortex (V1) result in scotomas in which only rudimentary visual abilities remain. These aspects of vision that survive V1 lesions have been attributed to direct thalamic pathways to extrastriate areas, including the middle

Revised Swedish visual field standards for a driver's licence: Threshold perimetry as a predictor of eligibility according to the current Swedish and current Norwegian suprathreshold standards

Acta Ophthalmologica, EarlyView.
Abstract Purpose To explore whether threshold perimetry can predict fulfilment of the current Swedish and current Norwegian Esterman perimetry standards for Group 1 driver's licence, and differences in compliance between the former and current Swedish visual field standards.

Programmable remapper for image processing [PDF]

, 1991
A video-rate coordinate remapper includes a memory for storing a plurality of transformations on look-up tables for remapping input images from one coordinate system to another. Such transformations are operator selectable.
