Corneal power modelling with OCT data – Thin and thick lens paraxial models versus raytracing

Acta Ophthalmologica, EarlyView.
Abstract Background Evaluating keratometric power with Zeiss index (PKZ), paraxial thick cornea power (Gullstrand [PG]) and power referenced to the front (PFV) and back vertex plane (PBV) and raytracing power (PR), and modelling the deviation from PKZ with a multivariable linear prediction model.

Changes in choroidal and retinal thickness 6 months before and during 18 months of orthokeratology lens treatment in myopic children

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate changes in choroidal and retinal thickness before and during myopia control treatment with orthokeratology lenses (OKL) in myopic children. Methods This was a sub‐study of CONTROL and CONTROL2 studies. The present study was a 2‐year, prospective, single‐group interventional study consisting of a 6‐month pre‐treatment ...

Astigmatism-type-specific impact of peripheral corneal thickness on anterior keratometric profile changes after temporal clear corneal incision cataract surgery

Scientific Reports
Postoperative astigmatism remains a concern after temporal clear corneal incision (TCCI) cataract surgery, especially in eyes with preexisting corneal astigmatism. This study investigated whether peripheral-to-central corneal thickness ratios can predict

The differences in essential facial areas for impressions between humans and deep learning models: An eye‐tracking and explainable AI approach

British Journal of Psychology, EarlyView.
Abstract This study explored the facial impressions of attractiveness, dominance and sexual dimorphism using experimental and computational methods. In Study 1, we generated face images with manipulated morphological features using geometric morphometrics. In Study 2, we conducted eye tracking and impression evaluation experiments using these images to

Factors influencing central corneal thickness

, 2017
Muchos factores determinan el espesor corneal y nuestro entendimiento del mismo no es suficiente. Esto es de gran interés teniendo en cuenta la relevancia de este parámetro oftalmológico en el manejo de varias condiciones clínicas como: la cirugía refractiva ola hipertensión ocular.

Stromal Curvature, Power and Corneal‐Stromal Curvature Ratios From a Hybrid AS‐OCT in Eyes With Keratoconus

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background To characterise stromal curvature and curvature ratios in keratoconus (KCN) using anterior segment OCT, and to evaluate the implications of using single‐, two‐, and three‐surface refractive models for corneal power estimation in ectatic eyes. Methods Retrospective observational study.

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

Clinical Genetics, EarlyView.
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.
