Premyopia Management With Ophthalmic Referral Slows Myopic Shift After School Entry: A Population‐Based Longitudinal Study in Taiwan

open access: yesClinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background This study aimed to evaluate the impact of early ophthalmic referral for premyopic preschoolers on myopic spherical equivalent (SE) shift after school entry; and to identify risk factors for nonadherence to follow‐up care. Methods A population‐based longitudinal study followed 742 premyopic preschoolers (−0.5 D < SE ≤ +0.75 D) from ...

Expanding the Genetic and Phenotypic Spectrum of POLRMT‐Related Mitochondrial Disease

open access: yesClinical Genetics, EarlyView.
We identified potentially damaging monoallelic and biallelic POLRMT variants in affected individuals from six unrelated families, thus extending both the clinical and genetic phenotypes of POLRMT‐related mitochondrial disease. ABSTRACT Mitochondrial diseases are a complex group of conditions exhibiting significant phenotypic and genetic heterogeneity ...
