| Abstract |
|
Myopia, among the most common vision disorders worldwide, is projected to affect approximately 50% of the world's population by 2050. Its prevalence is particularly high in East Asia, posing a considerable public health challenge. In particular, high myopia, defined as ≤6.0 diopters, significantly increases an individual's lifetime risk of vision-threatening complications. Moreover, recent studies revealed that non-ophthalmological factors such as body stature, sleep patterns, and nutritional status are strongly correlated with the progression of myopia, particularly in childhood and adolescence, underscoring the need for a systemic approach to its control. Current therapeutic approaches include optical correction, pharmacological treatment, and increased outdoor activity. Optically, defocus-incorporated multi-segment spectacle lenses and orthokeratology have shown efficacy at controlling the progression of myopia through peripheral retinal defocus and corneal reshaping, respectively. Pharmacologically, atropine eye drops, especially at low concentrations (0.05%), have demonstrated efficacy at myopia control with minimal side effects, making them a preferred treatment option for progressive myopia. Behaviorally, increased outdoor activity (minimum 2 h daily) and decreased excessive near work, particularly on digital devices, can help prevent the progression of myopia. Furthermore, studies have aimed to prevent the progression from pre-myopia to myopia. |
