Daily life vision captured in a ‘flower’
Visual crowding shows that it is harder to recognize objects when these are surrounded by similar objects, such as in a cluttered environment. The phenomenon has relevance in various ophthalmic and neurological disorders. Assessing crowding can be considered a laboratory … Continued
A I or A eye, that’s no longer the question
Eye movements are an integral and critical part of our normal visual behavior, and evaluating these may offer valuable insights for clinical interventions, diagnostics, and understanding visual perception. With raising interest in studying gaze behavior in freely moving participants and … Continued
Grant awarded for the “Virtual Reality for enhanced Visual Rehabilitation” (VR4eVR) project
Visual rehabilitation for hemianopia, which may be necessary after a stroke, can take a long time. Wouldn’t it be very useful if one could do this in the comfort of one’s own home? The answer is obviously ‘yes’, but how … Continued
Congratulations, dr. Marouska!

Visual Hallucinations and the Curious Absence of Activity in the Primary Visual Cortex
Visual hallucinations are perceptions without a physical stimulus to relate this percept too. It affects millions of people, yet surprisingly little is known about what’s happening in the brain during visual hallucinations. Marouska van Ommen and co-authors published a paper … Continued
The details are in the contrast
There is a need for simpler methods of perimetry – the measurement of retinal sensitivity at different visual field locations. In a recent paper in the journal Vision Research, Anne Vrijling, Minke de Boer and colleagues describe how contrast affects … Continued
15 PhD positions in Advanced Glaucoma Research in NL/DE/FR/NO
Glaucoma is the most common age-related neurodegenerative eye disease in Western society and one of the four major eye diseases causing blindness. Unfortunately, current treatments can only slow the deterioration but do not halt or reverse the process. Despite the … Continued
Fog illusion
Recently, science journalist Karel Knip of Dutch newspaper NRC handelsblad asked Frans Cornelissen the question of whether objects could appear larger in fog or at dusk than they really are. In his column he cites some sources that had claimed … Continued
Adult brain retains local neuroplasticity in glaucoma
To fully understand the eye disease glaucoma, it is important to also understand whether the adult human brain retains the ability to adapt to damage at the level of the eye. In a recent paper in the journal Scientific Reports, … Continued
