Globally, myopia is the leading cause of distance refractive error, affecting 1.45 billion or 27% of the world’s population in 2010 (myopia being defined as more than or equal to 0.50 D of myopia).1 The number of people with myopia is expected to continue to rise both in absolute numbers and as a percentage of the population.2 In certain age groups in several Asian countries, the prevalence of ...

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...

PURPOSE To describe a patient with intrachoroidal cavitation in the normal eye that caused self-limiting recurrent macular detachment and retinoschisis. CASE REPORT An 80-year-old female patient with intrachoroidal cavitation in the normal eye presented with macular detachment and retinoschisis after cataract surgery. These were treated with intravitreal bevacizumab and then absorbed within 9...
