Is the Change in Prevalence of High Myopia Compared to That of Myopia Really Disproportionate?

ABSTRACT:

Purpose

It has been noted that, at higher prevalences, the rate of change in the prevalence of high myopia seems to be disproportionately greater compared with the rate of change in the prevalence of myopia. A simple, evidence-based explanation for this relationship is offered.

Methods

Using a convenience sample of 41 datasets with prevalence estimates for at least two refractive error thresholds (e.g., -0.50 and -6.00 D) the common slope of the logit vs. refractive threshold was applied to model expected rates of high myopia across the myopia prevalence range and the corresponding ratio of change in high myopia to myopia prevalence.

Results

The logit of high myopia is related linearly to the logit of myopia. The ratio of increase in high myopia prevalence to that for
