PURPOSE To determine the changing prevalence of myopia during the years 1990 through 2002 among the 16- to 22-year age group and identify possible risk factors. METHODS A retrospective study, based on 13 repeated prevalence surveys conducted over a 13-year period. The study subjects were all Israeli nationals belonging to the 16- to 22-year age group from the years 1990 to 2002. Refraction wa...

The aim of this review was to quantify the global variation in childhood myopia prevalence over time taking account of demographic and study design factors. A systematic review identified population-based surveys with estimates of childhood myopia prevalence published by February 2015. Multilevel binomial logistic regression of log odds of myopia was used to examine the association with age, ge...

PURPOSE We explored risk factors for myopia in 12- to 13-year-old children in Northern Ireland (NI). METHODS Stratified random sampling was performed to obtain representation of schools and children. Cycloplegia was achieved using cyclopentolate hydrochloride 1%. Distance autorefraction was measured using the Shin-Nippon SRW-5000 device. Height and weight were measured. Parents and children c...

PURPOSE To evaluate bilateral myopia following blunt trauma to one eye. CASE REPORT Traumatic myopia is a rare transient situation which may be seen in the injured eye or both eyes after blunt ocular trauma. We examined one case with transient myopia in the left eye which had been exposed to a blunt ocular injury. Myopia was also observed in the right eye 12 hours after the trauma. The right ...

AIMS To report success in the treatment of high myopia in children with LASIK. To report the visual results, complications and postoperative management of children with high myopia. METHODS Six children (seven eyes) with high myopia were included in this series. Preoperative and postoperative refraction, visual acuity, and pachymetry were compared. RESULTS Six children with high myopia rang...

INTRODUCTION Hepatocyte growth factor (HGF) and hepatocyte growth factor receptor (C-MET) genes have previously been reported to be associated with myopia in Asian family-based and case-control association studies, respectively. We examined whether these genes were associated with myopia in a Caucasian family dataset biased towards high myopia. METHODS Participating families had at least one ...

Myopia is a common disorder, affecting approximately one-third of the US population and over 90% of the population in some East Asian countries. High amounts of myopia are associated with an increased risk of sight-threatening problems, such as retinal detachment, choroidal degeneration, cataracts, and glaucoma. Slowing the progression of myopia could potentially benefit millions of children in...

PURPOSE High myopia is a common genetic variant that severely affects vision. Genes responsible for myopia without linked additional functional defects have not been identified. Mutations in the nyctalopin gene (NYX) located at Xp11.4 are responsible for a complete form of congenital stationary night blindness (CSNB1). High myopia is usually observed in patients with CSNB1. This study was desig...

AIM To evaluate the incidence and progression of myopia and factors associated with progression of myopia in school going children in Delhi. METHODS Prospective longitudinal study of 10,000 school children aged 5 to 15 years screened after an interval of 1 year to identify new myopes (Spherical Equivalent≤ -0.5D) and progression of myopia in previously diagnosed myopic children. Association b...

BACKGROUND The purpose of this study was to evaluate the relationship between patterns of localized retinal nerve fiber layer (RNFL) defects and the degree of myopia in patients with normal-tension glaucoma (NTG). METHODS We retrospectively reviewed medical records of patients with high myopia (42 eyes; spherical equivalent [SE] < -6.0 diopters [D]), low to moderate myopia (93 eyes; SE -6.0D ...
