Regulatory oversight on the use of experimental therapies during a pandemic: The case of early access to convalescent plasma therapy in three LMICs
(Peer reviewed; Journal article, 2021)Clinicians, especially in low- and middle-income countries (LMICs), contend with limited economic and healthcare resources in deciding appropriate and feasible care for their patients. Some of the LMICs affected by COVID-19 ... -
The Relationship Between Perifoveal L-Cone Isolating Visual Acuity and Cone Photoreceptor Spacing—Understanding the Transition Between Healthy Aging and Early AMD
(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 ... -
Repeatability of OCT-Based versus Scheimpflug- and Reflection-Based Keratometry in Patients with Hyperosmolar and Normal Tear Film
(Peer reviewed; Journal article, 2020)Purpose: To compare the repeatability of keratometry between different instruments in patients with hyperosmolar tear film and a control group. Patients and Methods: Subjects with tear-film osmolarity of 316 mOsm/L or ... -
Reporting radiographers in Norway – A qualitative interview study
(Peer reviewed; Journal article, 2023)Introduction: A number of Norwegian radiographers have attended an advanced programme of education and training in musculoskeletal reporting, some in the UK and some in Norway. The aim of this study was to examine how ... -
Risk of hematological malignancies from CT radiation exposure in children, adolescents and young adults
(Peer reviewed; Journal article, 2023)Over one million European children undergo computed tomography (CT) scans annually. Although moderate- to high-dose ionizing radiation exposure is an established risk factor for hematological malignancies, risks at CT ... -
Role of stem cells in regenerative treatment of dry eye disease caused by lacrimal gland dysfunction
(Peer reviewed; Journal article, 2022)An ageing population and increased screen use in younger people have contributed to a rise in incidence of dry eye disease (DED). Quality of life can be significantly affected by DED, with patients experiencing eye dryness, ... -
Saccade latency and fixation stability: Repeatability and reliability
(Journal article; Peer reviewed, 2016)This study aimed to investigate the repeatability and reliability of saccadic latency and fix-ation stability as a function of sighting-dominance and contact lens wear. Eye movements were recorded in 12 healthy adults who ... -
Screening of Diabetes Retinopathy in Optometry: Assessment of a Web-based Training Protocol
(Journal article; Peer reviewed, 2017)Diabetic retinopathy is a sight threatening complication of diabetes mellitus. Regular eye examinations by trained health professionals can help prevent this. Although ophthalmologists have screening responsibility in ... -
