Uncorrected low hyperopia in young subjects induces postural instability even in those with clear visual acuity.

open access: yesPLoS ONE, 2019
Reports have indicated the effect of myopic blur on postural stability. The objective of this study was to investigate the minimum refractive error to significantly affect postural stability through a various levels of hyperopia and myopia induced by ...

Latent hyperopia as a hidden contributor to post-COVID-19 asthenopia: A cross-sectional study in young adults with normal visual acuity

open access: yesJournal of Clinical Ophthalmology and Research
Background: Post-COVID-19 escalation in digital device use and sustained near work has increased accommodative load in young adults, frequently unmasking latent hyperopia and triggering asthenopia even in those with normal distance acuity.

Clinical, Behavioral and Neuroradiological Phenotype in an Italian Cohort of Patients With Xia Gibbs Syndrome: A Multicenter Cross‐Sectional Study and Systematic Literature Review

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous variants in the AHDC1 gene are associated with Xia Gibbs Syndrome (XGS), a genetic disorder with a highly variable phenotype. Cognitive impairment, motor delay, language delay, neonatal hypotonia, and sleep apnea are considered “cardinal” signs of the disease.

Hypermetropia, myelinated retinal nerve fiber and amblyopia: Reverse straatsma syndrome

open access: yesTNOA Journal of Ophthalmic Science and Research, 2022
Myelinated retinal nerve fibers (MRNF) are a common developmental anomaly. MRNF is commonly associated with myopia. The association of MRNF with myopia, amblyopia, and strabismus is well documented. The amblyopia may be refractory to treatment. We report

The effect of unilateral disruption of the centrifugal visual system on normal eye development in chicks raised under constant light conditions [PDF]

open access: yes, 2016
The centrifugal visual system (CVS) comprises a visually driven isthmic feedback projection to the retina. While its function has remained elusive, we have previously shown that, under otherwise normal conditions, unilateral disconnection of centrifugal ...

De Novo 2.2 Mb 19q13.42–q13.43 Microdeletion Encompassing U2AF2: Support for a Haploinsufficiency Model

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT U2 small nuclear RNA auxiliary factor 2 (U2AF2) is an essential pre‐mRNA splicing factor involved in the early stages of pre‐mRNA splicing. To date, multiple individuals have been reported with predominantly heterozygous missense variants presenting intellectual disability, speech and motor delays, seizures, hypotonia, and thin or hypoplastic ...
