Posterior corneal surface stability after femtosecond laser-assisted keratomileusis [PDF]

open access: yes, 2015
The purpose of this study was to evaluate posterior corneal surface variation after femtosecond laser-assisted keratomileusis in patients with myopia and myopic astigmatism. Patients were evaluated by corneal tomography preoperatively and at 1, 6, and 12

Two New Cases Expand the Phenotypic Spectrum of TUBG1 Missense Variants

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The gamma‐tubulin ring complex (γ‐TuRC) plays a role in coordinating centrosome and spindle pole body formation during cell division. TUBG1 encodes a critical component of the γ‐TuRC. Pathogenic TUBG1 variants can cause a range of alterations in cortical gyral patterning, microcephaly, and other neurological manifestations.

Posterior corneal astigmatism: a review article

open access: yesClinical Optometry, 2019
Most human eyes show at least a small degree of corneal astigmatism and it can arise from both surfaces of the cornea. The shape of the anterior corneal surface provides no definitive basis for knowing the toricity of the posterior surface.

Phenotypic Characterization of Seven Pediatric Patients Diagnosed With KAT6B‐Related Disorders: Case Series and Review of the Literature

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Genitopatellar syndrome (GPS) and Say‐Barber‐Biesecker‐Young‐Simpson Syndrome (SBBYSS) are clinically distinct neurodevelopmental disorders caused by monoallelic pathogenic variants in KAT6B. In some cases, GPS and SBBYSS features can overlap, determining an intermediate phenotype.
