The prevalence of high myopia is projected to significantly increase, rising from 15% in college students to over 45% post-graduation. This trend highlights the growing burden of myopia progression in higher education settings.

Area of Science:

  • Ophthalmology
  • Public Health
  • Biostatistics

Background:

  • High-percentage, high-incidence medical conditions often exhibit a characteristic age of onset and progression pattern.
  • Understanding these patterns is crucial for conditions like myopia, which affect a significant portion of the population.

Purpose of the Study:

  • To investigate the prevalence and incidence functions of myopia and high myopia as a function of age.
  • To develop continuous prediction models for myopia prevalence and incidence over time.

Main Methods:

  • A retrospective study analyzing data from nine reports, encompassing 444,600 subjects.
  • Utilized fundamental prevalence and incidence data to establish predictive models.
  • No interventions were applied beyond standard eye examinations and refractive correction.

Main Results:

  • Developed continuous prediction models for myopia prevalence and incidence rates (%/year).
  • Identified key parameters including age of onset (years), system plateau level, and system time constant (years).
  • These models are applicable to progressive myopia and high myopia (R < -6 D) over extended periods.

Conclusions:

  • The ratio of high myopes (R < -6.0 D) to common myopes is expected to increase substantially, from 15% upon college entry to over 45% after graduate studies.
  • This increasing prevalence of high myopia is particularly relevant for individuals pursuing demanding academic programs like M.D. and Ph.D. degrees.
