MI-SIGHT, Michigan Screening and Intervention for Glaucoma and Eye Health through Telemedicine; VFQ, Visual Function Questionnaire; SE, Spherical Equivalent; SD, Standard Deviation
*
Moderate Hyperopia is defined as SE 3–4.99, n=25; High Hyperopia is defined as SE≥5, n=3; categories were combined due to the small sample size of high hyperopes;
**
Kruskal-Wallis test
Post-hoc pairwise comparisons with Dwass, Steel, Critchlow-Fligner multiple comparison procedure showed significant differences between:
a
High myopia versus Mild hyperopia,
b
Moderate myopia versus Mild hyperopia,
c
Mild myopia versus No myopia/hyperopia
