A Demonstration of 'Broken' Visual Space
Svarverud, Ellen; Gilson, Stuart; Glennerster, Andrew (Journal article; Peer reviewed, 2012)It has long been assumed that there is a distorted mapping between real and ‘perceived’ space, based on demonstrations of systematic errors in judgements of slant, curvature, direction and separation. Here, we have applied ... -

(Peer reviewed; Journal article, 2019)Purpose Investigate in vivo cone photoreceptor structure in familial aniridia caused by deletion in the PAX6 gene to elucidate the complexity of between-individual variation in retinal phenotype. Design Descriptive ... -
The effect of topical 1 % atropine on ocular dimensions and diurnal rhythms of the human eye
Nilsen, Nickolai Godtfred; Gilson, Stuart; Pedersen, Hilde Røgeberg; Hagen, Lene Aarvelta; Wildsoet, Christine F.; Baraas, Rigmor (Peer reviewed; Journal article, 2023)The effect of topical 1 % atropine on the diurnal rhythms of the human eye was investigated. Participants wore an activity monitor on Days 1–7. A set of measures (epochs) encompassing intraocular pressure (IOP), ocular ... -
Emmetropia Is Maintained Despite Continued Eye Growth From 16 to 18 Years of Age
Hagen, Lene Aarvelta; Gilson, Stuart; Akram, Muhammad Nadeem; Baraas, Rigmor C. (Journal article; Peer reviewed, 2019)PURPOSE. To examine, in Norwegian adolescents, to what degree emmetropia and low hyperopia were maintained from 16 to 18 years of age, and if this was the case, whether it was associated with continued coordinated ocular ... -
Multimodal imaging of small hard retinal drusen in young healthy adults.
Pedersen, Hilde Røgeberg; Gilson, Stuart; Dubra, Alfredo; Munch, Inger Christine; Larsen, Michael; Baraas, Rigmor C. (Journal article; Peer reviewed, 2017)Background Small hard macular drusen can be observed in the retina of adults as young as 18 years of age. Here, we seek to describe the in vivo topography and geometry of these drusen. Methods Retinal images were acquired ... -
Multimodal in-vivo maps as a tool to characterize retinal structural biomarkers for progression in adult-onset Stargardt disease
Pedersen, Hilde Røgeberg; Gilson, Stuart; Hagen, Lene Aarvelta; Holtan, Josephine Prener; Bragadottir, Ragnheidur; Baraas, Rigmor C. (Peer reviewed; Journal article, 2024)Purpose: To characterize retinal structural biomarkers for progression in adult-onset Stargardt disease from multimodal retinal imaging in-vivo maps. Methods: Seven adult patients (29–69 years; 3 males) with genetically-confirmed ... -
The need for cycloplegic refraction in adolescents and young adults
Hagen, Lene Aarvelta; Gilson, Stuart; Baraas, Rigmor C. (Peer reviewed; Journal article, 2023)Cycloplegic refraction is considered the gold standard method when examining children and for ensuring accurate refractive error assessment within epidemiological studies. Recent reports underline that cycloplegia is equally ... -

The Relationship Between Perifoveal L-Cone Isolating Visual Acuity and Cone Photoreceptor Spacing—Understanding the Transition Between Healthy Aging and Early AMD
Baraas, Rigmor C.; Horjen, Åshild Bøysen; Gilson, Stuart; Pedersen, Hilde R. (Peer reviewed; Journal article, 2021)Background: Age-related macular degeneration (AMD) is a multifactorial degenerative disorder that can lead to irreversible loss of visual function, with aging being the prime risk factor. However, knowledge about the ... -
