Near visual function measured with a novel tablet application in patients with astigmatism

open access: yesClinical and Experimental Optometry, EarlyView., 2020
Clinical relevance While the clinical focus of performance metrics is traditionally based on visual acuity, research from the field of visual impairment has demonstrated that metrics such as reading speed and critical print size correlate much more strongly with subjective patient reported outcomes and assessed ability in real‐world tasks.

Correlation Between Stereoacuity and Experimentally Induced Graded Monocular and Binocular Astigmatism [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2016
Introduction: Stereopsis, the highest grade of binocular single vision, is affected by various factors, such as mis-alignment of visual axes, refractive errors especially anisometropia and astigmatism, both of which may result in amblyopia. There are

Defining Features of Gabriele‐de Vries Syndrome in Adults: A Case Report and Literature Review

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Gabriele‐de Vries syndrome (GADEVS) is a neurodevelopmental disorder caused by heterozygous pathogenic variants in the YY1 gene. Like most rare genetic syndromes, the adult manifestations of GADEVS remain poorly defined. Here, we describe the oldest patient reported to date with GADEVS—a 63‐year‐old woman with a c.1177_1179del YY1 variant ...
