OBJECTIVE Progressive myopia in humans and lid-sutured myopia in primates have been considered to be different processes. This report seeks to establish the connection between progressive myopia in humans and lid suture myopia in macaque monkeys. METHODS We followed the axial length of 4 lid-sutured macaque monkeys over an 18 month period. Their axial length is directly related to myopia. We ...

PURPOSE To estimate the sibling recurrence risk (KS) and the sibling recurrence risk ratio (lambda(S)) for high myopia in a cohort in the United Kingdom. METHOD The recurrence risks for myopia and high myopia were estimated in the siblings of 296 randomly selected high myopes ascertained from an optometric practice population. A model using an age of onset of spectacle wear for myopia of 9.1 ...

Purpose: The purpose of this study was to determine the distribution iris colour and its relationship myopia. Methods: A multi-centered, multi-disciplined, cross-sessional conducted From March 2021 December 2021. 300 individuals ranging in age from 11 25 years were selected through non-probability purposive sampling technique. All patients had a maximum 6 hours screen time. Mild, moderate sever...

We have been observing patients with progressive myopia, both adult ones and children from the age of 1 year, for 30 years. From our studies into the natural course of myopia, we have established the following age-related development patterns of chorioretinal dystrophies. Whilst central chorioretinal dystrophies (CCRD) emerge as a rule at an age of 30 or older (with the exception of cases of co...

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...

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...
