MIOPIA

Abstract: The prevalence of myopia is high and increasing. Approximately 5 billion people around the world are expected to be myopic by the year 2050. Methods to slow the progression of myopia and therefore potentially decrease the associated sight-threatening complications have been the subject of a number...

Abstract: Myopia occurs in more than 50% of the population in many industrialized countries and is expected to increase; complications associated with axial elongation from myopia are the sixth leading cause of blindness. Thus, understanding its etiology, epidemiology, and the results of various treatment regiments may...

Abstract Purpose To gauge the extent to which differences in the refractive error axial length relationship predicted by geometrical optics are observed in actual refractive/biometric data. Methods This study is a retrospective analysis of existing data. Right eye refractive error...

Abstract Purpose With the increasing prevalence in myopia there is growing interest in active myopia prevention. This study aims to increase our understanding of parental attitudes to myopia development and control, as a means to inform future health planning and...

Abstract Purpose Despite extensive research, mechanisms regulating postnatal eye growth and those responsible for ametropias are poorly understood. With the marked recent increases in myopia prevalence, robust and biologically‐based clinical therapies to normalize refractive development in childhood are needed. Here,...

SIGNIFICANCE Practitioners fitting contact lenses for myopia control frequently question whether a myopic child can achieve good vision with a high-add multifocal. We demonstrate that visual acuity is not different than spectacles with a commercially available, center-distance soft multifocal contact lens...

Introduction: The peripheral refractive error of the human eye has been hypothesized to be a major stimulus for the development of its central refractive error. Aim: The purpose of this study was to investigate the changes in the peripheral refractive error across...

Recent increases in global myopia prevalence rates have raised significant concerns as myopia increases the lifelong risk of various sight-threatening ocular conditions. This growing public health burden has generated significant research interests into understanding both its aetiology and developing effective...

Punti Chiave :    Sono stati testate lenti per occhiali disegnate per modificare la visione periferica, riducendone il defocus ipermetropico   Si sono osservati errori di potere centrale     Abstract Purpose Radial Refractive Gradient (RRG) spectacles are lenses specifically...

Abstract Purpose: To test the hypothesis that genes known to cause clinical syndromes featuring myopia also harbor polymorphisms contributing to nonsyndromic refractive errors. Methods: Clinical phenotypes and syndromes that have refractive errors as a recognized feature were identified using the Online Mendelian...

Objectives: To determine the rate of myopia progression in children fit with a commercially available extended depth of focus (center distance) multifocal soft contact lens with attributes theoretically expected to slow the progression of myopia. Methods: A retrospective case series...

Abstract Purpose To describe longitudinal changes in corneal curvature (CC) and axial length (AL) over 14 years, and to explore the relationship between AL and CC, and the axial length/corneal radius (AL/CR) ratio. Methods In total 469, 6 to <12-year-old,...

Abstract Purpose To determine whether the initial characteristics of individual patterns of peripheral refraction relate to subsequent changes in refraction over a one-year period. Methods 54 myopic and emmetropic subjects (mean age: 24.9±5.1 years; median 24 years) with normal vision...

Purpose: To determine whether soft contact lenses with positive spherical aberration (+SA) can slow myopiaprogression. Methods: Eligible subjects (N = 127, primarily Asian) aged 8 to 11 years were randomized to wear either control(spherical design) or test (with +SA) soft daily disposable contact lenses for a minimum of 1 and up to 2 years (treatment phase). Subjects...

Abstract: Slowing the progression of myopia has become a considerable concern for parents of myopic children. At the same time, clinical science is rapidly advancing the knowledge about methods to slow myopia progression. This article reviews the peer-reviewed literature regarding...

Purpose: Higher myopic refractive errors are associated with serious ocular complications that can put visual function at risk. There is respective interest in slowing and if possible stopping myopia progression before it reaches a level associated with increased risk of...
