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 ...

Predictive Correction Model for Corneal Back Surface Astigmatism With IOLMaster700 Keratometry Data in a Cataractous Population

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background To develop and validate various models to predict total keratometry (TK) power vector components TKC0 and TKC45 from classical keratometry (K) KC0 and KC45 based on a large dataset of pre cataract surgery IOLMaster 700 measurements.

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.
