The Phenotypic and Genotypic Features of ADAMTSL4‐Related Ocular Disease

open access: yesClinical Genetics, EarlyView.
ADAMTSL4‐related ocular disease tends to present at a younger age and be associated with higher myopia than other forms of ectopia lentis (such as FBN1). A previously reported 20‐bp deletion (c.767_786del) was highly prevalent in this cohort (23/32), and all ectopia lentis et pupillae cases carried this variant. ABSTRACT Pathogenic variants in ADAMTSL4

Retinal Pigment Epitheliopathy due to Sub‐Optimal Recycling of Vitamin A (RESORVA): A Novel RDH11‐Related Phenotype

open access: yesClinical Genetics, EarlyView.
RDH11 is a minor isoenzyme that catalyses the oxidation of 11‐cis‐retinol to 11‐cis‐retinal in the retinal pigment epithelium, alongside RDH5 and RDH10. Biallelic null variants in RDH11 lead to upregulation of RDH5 and RDH10 (transcriptional adaptation), maintaining 11‐cis‐retinal bioavailability, but still causing Retinal Pigment Epitheliopathy due to

Prevalence and profile of astigmatism in individuals availing ophthalmic services at Central Regional Referral Hospital, Gelephu, Bhutan: A cross-sectional, hospital-based study

open access: yesBhutan Health Journal
Introduction: Astigmatism has been defined as a type of refractive error when parallel rays of light entering the eye are not focused at one point of the retina when accommodation is at rest due to irregular curvature of the cornea or lens surface.

Association between glucagon‐like peptide‐1 receptor agonists and risk of dementia in older adults with type 2 diabetes: A target trial emulation

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
Abstract Aim Type 2 diabetes (T2D) is associated with increased dementia risk, but comparative data across newer glucose‐lowering therapies remain limited. We examined whether the initiation of GLP‐1 receptor agonists (GLP‐1 RAs) was associated with incident dementia compared with DPP4 inhibitors (DPP4is) and SGLT2 inhibitors (SGLT2is) in older adults ...

Genome-wide association studies for corneal and refractive astigmatism in UK Biobank demonstrate a shared role for myopia susceptibility loci

open access: yesHuman Genetics, 2018
Previous studies have suggested that naturally occurring genetic variation contributes to the risk of astigmatism. The purpose of this investigation was to identify genetic markers associated with corneal and refractive astigmatism in a large-scale ...

Evidence for increased background neural noise in migraine with aura: Hyperactive but not hyperresponsive

open access: yesHeadache: The Journal of Head and Face Pain, EarlyView.
Abstract Objective This study had two aims: (1) to investigate the contrast gain in migraine and compare it to that in photosensitive epilepsy; (2) to explore any effects of colored spectacles (precision ophthalmic tints [POT]) on contrast gain. Background Individuals with migraine with aura (MA) typically show high amplitude electrophysiological ...
