The Role of Scalp EEG Recordings During Cortical Visual Prosthesis Testing

open access: yesArtificial Organs, EarlyView.
This article describes the role of recording scalp EEG for projects that are developing cortical visual prosthesis systems. It concludes that EEG is not required during basic threshold and spatial mapping studies, but should be considered when higher levels of stimulation and video‐camera stimulation are employed.

Clinical disorders affecting mesopic vision [PDF]

open access: yes, 2006
Vision in the mesopic range is affected by a number of inherited and acquired clinical disorders. We review these conditions and summarize the historical background, describing the clinical characteristics alongside the genetic basis and molecular ...

Tracking visual outcomes – Follow‐up on patients born preterm with childhood‐onset visual impairment

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Preterm birth is associated with a risk of ocular complications. The primary aim of the study was to evaluate the main cause of visual impairment (VI) in a cohort of preterm born patients who had childhood‐onset VI. The association between health‐related quality of life (HRQoL) and age, cause—and severity of VI and impairment type was ...

Choroidal changes and association with Gaussian curvature in high myopic eyes with posterior staphyloma in ultra‐wide‐field optical coherence tomography angiography

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To evaluate choroidal changes in high myopic (HM) patients with posterior staphyloma (PS) and explore their association with Gaussian curvature (K) using ultra‐wide‐field optical coherence tomography angiography (UWF‐OCTA). Methods HM patients with wide macular PS (Type I PS) and without any PS (control) were recruited.

Morphological changes of sclera in rats with experimental myopia [PDF]

open access: yesМорфологія, 2014
Background. The absence of adequate experimental myopia model is the actual problem in pathophysiological studying of the myopia progression. Studies of the chick eye have formed the basis for several hypotheses of myopic development.

The Choroid and Optical Coherence Tomography

open access: yesTürk Oftalmoloji Dergisi, 2016
The choroid is the most vascular tissue in the eye and it plays an important role in the pathophysiology of various common chorioretinal diseases such as central serous retinopathy, age-related macular degeneration and degenerative myopia.

Genome-wide analysis points to roles for extracellular matrix remodeling, the visual cycle, and neuronal development in myopia [PDF]

open access: yesarXiv, 2012
Myopia, or nearsightedness, is the most common eye disorder, resulting primarily from excess elongation of the eye. The etiology of myopia, although known to be complex, is poorly understood. Here we report the largest ever genome-wide association study (43,360 participants) on myopia in Europeans.

Molecular and cellular mechanisms underlying gyrate atrophy: Why is the retina primarily affected?

open access: yesActa Ophthalmologica, EarlyView.
Abstract Gyrate atrophy of the choroid and retina (GACR; OMIM #258870) is a rare early‐onset autosomal recessive disorder, caused by bi‐allelic pathogenic variants in the gene coding for ornithine aminotransferase (OAT) resulting in hyperornithinaemia.
