[Biological mechanisms of myopia]

Area of Science:

• Ophthalmology
• Developmental Biology
• Public Health

Background:

• Myopia prevalence is increasing globally, linked to environmental factors and education levels.
• Extensive close-up work, limited outdoor activity, and low illumination are suspected major contributors.
• The mechanism by which close-up work stimulates eye growth remains unclear.

Purpose of the Study:

• To investigate the environmental factors contributing to myopia progression.
• To explore the efficacy of low-dose atropine in managing myopia.
• To understand the impact of visual experiences on eye growth using animal models.

Main Methods:

• Utilizing animal models to manipulate visual experiences and observe eye growth changes.
• Reviewing recent studies on myopia prevalence and risk factors.
• Analyzing the effects of low-dose atropine (0.01%) on myopia progression.

Main Results:

• Animal models have revealed unexpected aspects of visual experience influencing eye growth.
• Low-dose atropine (0.01%) is effective in inhibiting myopia progression.
• Unlike higher doses, low-dose atropine shows no rebound effect upon treatment cessation.

Conclusions:

• Environmental factors, particularly close-up work, significantly influence myopia development.
• Low-dose atropine presents a safe and effective strategy to slow myopia progression.
• Interventions can help mitigate the risk of developing high myopia, despite societal educational demands.
