Congenital aniridia: European COST action ANIRIDIA‐NET guidelines for diagnosis, management and care

Acta Ophthalmologica, EarlyView.
Abstract Congenital aniridia is a rare ocular disorder affecting the majority of eye structures and can be associated with systemic manifestations. The main visible phenotypic characteristic is the partial or complete absence of the iris; however, foveal hypoplasia is a more frequent and reliable clinical sign. Other ocular comorbidities are associated

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.

INFLUENCE OF TOPICAL ANAESTHETICS ON CORNEAL TOPOGRAPHY

Офтальмохирургия, 2015
Introduction. By now it is a well-established fact that topical anaesthetics have an influence on IntraOcular pressure. The topical anaesthetic will give a lower intraocular pressure reading.

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 ...

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.
