Genetic and environmental effects on myopia development and progression.

Area of Science:

• Ophthalmology
• Genetics
• Environmental Health

Background:

• Myopia, or nearsightedness, is a common refractive error.
• The aetiology of myopia is complex, involving both genetic predisposition and environmental influences.
• Low myopia, specifically, requires further elucidation regarding contributing factors.

Purpose of the Study:

• To review the interplay between genetic and environmental factors in the development of low myopia.
• To understand how genetic influences on eye growth are modulated by environmental exposures.
• To identify key environmental factors impacting refractive development.

Main Methods:

• Literature review of studies investigating myopia aetiology.
• Analysis of genetic components influencing ocular development.
• Examination of environmental factors such as education, metabolism, physical activity, and outdoor time.

Main Results:

• Genetics significantly determines eye growth patterns.
• Environmental factors critically affect the precise correlation of refractive components for emmetropia.
• Education, metabolism, physical activity, and outdoor activity are identified as key environmental modulators.

Conclusions:

• Both genetic and environmental factors are crucial in the aetiology of low myopia.
• Environmental exposures can modify genetically influenced refractive development.
• Understanding this interaction is vital for myopia prevention and management strategies.
