Simulated loss of foveal vision eliminates visual search advantage in repeated displays

Frontiers in Human Neuroscience, 2012
In the contextual cueing paradigm, incidental visual learning of repeated distractor configurations leads to faster search times in repeated compared to new displays. This contextual cueing is closely linked to the visual exploration of the search arrays

Visual acuity is reduced with increasing central retinal thickness, but also with higher age and female sex in diabetic macular oedema

Acta Ophthalmologica, EarlyView.
Abstract Introduction The increasing number of patients with diabetes has increased the incidence of diabetic macular oedema (DME) with the accompanying risk of developing visual loss. The purpose of the present study was to describe the contributions of increased central retinal thickness (CRT) and other risk factors to the reduction in visual acuity ...

A mathematical determination of foveal attachment in primary rhegmatogenous retinal detachment when obscured by bullous retina

International Journal of Retina and Vitreous, 2022
In primary rhegmatogenous retinal detachment (RRD), the foveal attachment is an important prognostic factors for post-operative vision. When the fovea is obscured by the RRD, its attachment status is considered uncertain.

Clinical manifestations of dual‐gene variants in retinitis pigmentosa

Acta Ophthalmologica, EarlyView.
Abstract Purpose Retinitis pigmentosa (RP) is an inherited retinal disease (IRD), whereby each affected individual typically harbours pathogenic variants in a single causative gene, yet the disorder exhibits marked genetic heterogeneity, with more than 100 genes reported to underlie RP.

Photoreceptor replacement therapy using a tissue scaffold shows evidence of donor-host integration in non-human primate retina

Stem Cell Reports
Summary: Retinal degeneration is characterized by progressive photoreceptor (PR) loss, leading to visual impairment and ultimately blindness. PR replacement is a promising therapeutic strategy, but surgical delivery remains challenging, and efficacy in ...

Eye Size, Fovea, and Foraging Ecology in Accipitriform Raptors

, 2017
Birds with larger eyes are predicted to have higher spatial resolution because of their larger retinal image. Raptors are well known for their acute vision, mediated by their deep central fovea.

Retinal dystrophies simulating geographic atrophy: A diagnostic challenge

Acta Ophthalmologica, EarlyView.
Abstract Geographic atrophy (GA) is the chronic loss of retinal pigment epithelium, photoreceptors and choriocapillaris, marking the dry late stage of age‐related macular degeneration (AMD). GA prevalence is expected to rise in the upcoming decades. Advanced GA leads to central scotomas, reducing visual acuity and quality of life, potentially resulting
