Non‐RASopathy Genetic Syndromes Identified as the Molecular Cause of Disease in Patients Previously Diagnosed With Noonan Syndrome

American Journal of Medical Genetics Part A, Volume 200, Issue 3, Page 661-672, March 2026.
ABSTRACT Noonan Syndrome (NS) is a clinically and genetically heterogeneous condition characterized by typical facial dysmorphisms, short stature, congenital heart defects, and developmental delays. While variants in genes such as PTPN11, SOS1, and RAF1 account for most genetically confirmed cases, diagnosis is challenging due to phenotypic overlap ...

Pentacam versus anterior segment OCT in measuring intended versus achieved ablation depth post-myopic LASIK correction

Beni-Suef University Journal of Basic and Applied Sciences, 2022
Background Accurate quantitative measurements of central corneal thickness (CCT) provide valuable, clinical information for preoperative assessment, surgical planning, and follow-up in myopic patients who have undergone LASIK correction.

Factors Contributing to Screen Exposure in Preschool Children and Its Associated Outcomes: A Systematic Review

Child: Care, Health and Development, Volume 52, Issue 2, March 2026.
ABSTRACT Objectives This systematic review aims to synthesise the current evidence on risk and protective factors that lead to prolonged screen exposure, and to identify both adverse and positive developmental outcomes associated with that screen exposure in preschool children. Materials and Methods Following PRISMA 2020 guidelines, a systematic search

Effect of pupil size on wavefront refraction during orthokeratology [PDF]

, 2016
Purpose. It has been hypothesized that central and peripheral refraction, in eyes treated with myopic overnight orthokeratology, might vary with changes in pupil diameter.

Laser intrastromal keratomileusis for high myopia and myopic astigmatism [PDF]

British Journal of Ophthalmology, 1997
Laser intrastromal keratomileusis (LASIK) is an evolving technique which enables high degrees of myopia (> 8.0 dioptres) and myopic astigmatism to be corrected. This paper describes initial experience with this procedure. It also details the methodology, the results, the problems encountered, and discusses retreatment procedures.51 eyes (48 primary ...

A Novel Homozygous Nonsense Pathogenic Variant of the CPAMD8 Gene Associated With Congenital Microcoria

Clinical Genetics, Volume 109, Issue 3, Page 571-575, March 2026.
A novel CPAMD8 nonsense mutation c.2679C>G (p.Tyr893*) was identified in a patient with congenital microcoria, leading to reduced mRNA expression and predicted protein truncation. ABSTRACT Congenital microcoria (MCOR) is a rare inherited ocular disorder. Here, we describe a novel nonsense variant in the CPAMD8 gene in a patient with MCOR.

Assessing Effects of Riboflavin/UV‐A Cross‐Linking on Aqueous Outflow Facility, Corneal Biomechanics and Their Association With Intraocular Pressure

Journal of Biophotonics, Volume 19, Issue 2, February 2026.
Our study demonstrates that UV cross‐linking (CXL) reduces outflow facility while increasing corneal elasticity across IOP levels of 20–40 mmHg, measured using direct manometry and non‐contact optical coherence elastography. These results highlight both parameters as potential indicators for evaluating CXL effectiveness and monitoring keratoconus ...
