BACKGROUND/OBJECTIVES: Myopia progression is of great concern because of its association with an increased risk of sight-threatening conditions. This study aims to determine whether certain clinical and optic disc features are associated with the rate of myopia progression.
SUBJECTS/METHODS: In this retrospective longitudinal observational study, we reviewed the medical records of 95 patients aged 6-11 years with myopia (spherical equivalent refractive error (SER) at baseline ≤ -0.5 D) and collected data regarding medical history, comprehensive ophthalmologic examination, and fundus photography. Using fundus photographs, we measured the ratio of horizontal to vertical disc diameter (HVDR), ratio of maximum β-zone peripapillary atrophy (β-PPA) width to vertical disc diameter (PVDR), and optic disc torsion. Outcome measurements included 2-year myopia progression (D/year) and overall myopia progression during the entire follow-up with a mean of 51 months.
RESULTS: Mean age at initial visit was 7.67 ± 1.50 years and mean SER at baseline was -2.91 ± 1.68 D (range, -5.75 to -0.50 D). In the univariate analysis, age, parental myopia, SER at baseline, HVDR, and PVDR were significantly associated with myopia progression (P < 0.05). In the multivariate analysis, however, only age at initial visit and PVDR were significant factors associated with both 2-year and overall myopia progression.
CONCLUSIONS: Children with younger age and smaller β-PPA at baseline showed a faster myopia progression. This study suggests that the width of β-PPA, regardless of SER, might be used as a quantitative parameter to predict the potential for further myopia progression associated with scleral stretching.
