We aimed to identify the prevalence and risk factors of myopia among secondary-school students in Amman. Thus 1777 (1081 males and 696 females) students aged 12-17 years old were recruited from 8 schools randomly selected from 8 different geographic locations in Amman. Data were collected by questionnaire, and self-reported myopia was checked against school medical records. The prevalence of my...

We propose a novel approach to evaluating the empirical importance of individual managerial characteristics: We analyze different managerial positions (CEO and CFO) jointly and ask whether a managerial bias (overconfidence) matters for decisions under the control of the manager, but not for decisions outside the manager’s core duties. Using a new data set on CEO and CFO overconfidence, we show ...

In the recent past, myopia was considered to be entirely due to inheritance and there is no doubt that a family history of myopia in parents is a risk factor for myopia in children. The increasing prevalence of myopia, however, has affected populations with no previous history of the condition, such as the Inuit where previously a hypermetropic (long-sighted) population now demonstrates a signi...

IMPORTANCE Visual impairment due to myopia is an important public health issue. A prior analysis of population-based cohorts aged 15 to 22 years recruited from the United Kingdom and Israel suggested myopia and high myopia were approximately 10% more common in first-born compared with later-born children. OBJECTIVE To examine whether myopia was associated with birth order in an earlier genera...

PURPOSE High myopia or pathological myopia is a common refractive error. Individuals with high myopia are subject to increased risk of serious eye complications. Accumulating evidence has demonstrated the role for heritability in ocular growth and in the development of high myopia. Retinoic acid and retinoic acid receptors play important roles in ocular development and in experimentally induced...

Refractive error (RE), particularly myopia, is the first cause of visual impairment throughout the world. This study aimed to depict the prevalence of myopia in a multicentric series of French individuals.This cross-sectional analysis was carried out between January 2012 and November 2013 in eye clinics dedicated to REs. Data collection included age, gender, best-corrected visual acuity, RE, an...

Investigations into the plasticity of eye growth and refractive error development have significantly expanded our knowledge of animal models of myopia in the last 15 yr. The applicability of this information is as yet undetermined, but hopefully this information will be useful in learning more about human myopia. This paper presents a critical review of the animal myopia literature as those dat...

PURPOSE We investigated the independent impact of potential risk factors on myopia in young adults. METHODS A survey study was conducted with male military conscripts aged 18 to 24 years between February 2010 and March 2011 in Taiwan. The participants were examined using non-cycloplegic autorefraction and biometry. The participants provided data about potential risk factors, including age, pa...

Myopia has become epidemic in the world. Without effective control, the progression may lead to excessive myopia with severe complications affecting vision and ocular alignment. The genetic factors and environmental factors of myopia are closely interrelated to each other. Asian ethnicity and parental myopia, among other genetic factors, influence the refractive outcome dramatically when enviro...
