Nearly one-third of children worldwide are already affected by this degenerative disease, with prevalence projected to exceed 740 million cases by 2050 (Liang et al., 2024). In North America, myopia prevalence is expected to reach nearly 60% by 2050, according to a landmark study published in Ophthalmology (Holden et al., 2016). The most rapid progression of the disease occurs in children ages 3 to 10 years (Hu et al., 2020), with patients who start progressing younger experiencing more severe outcomes and associated co-morbidities, including cataracts, glaucoma, retinal detachment, and myopic maculopathy. Despite its growing prevalence, there are currently no FDA-approved pharmaceutical options in the United States to slow the progression of PPM, representing a significant gap in available treatment options for patients.
