A Trial of Bifocals in Myopic Children With Esophoria

NCT00000128 · Status: UNKNOWN · Phase: PHASE3 · Type: INTERVENTIONAL

Last updated 2005-06-24

No results posted yet for this study

Summary

To test the hypothesis that correction with bifocal spectacle lenses rather than single-vision lenses will slow the progression of myopia in children with near-point esophoria. The primary outcome variable is cycloplegic refraction as measured with an automated refractor. Axial length is measured with ultrasound in order to test the corollary hypothesis that use of bifocals will slow ocular growth in these myopic children. We will also examine the amount of close work performed by subjects and the degree of parental myopia as factors that may influence myopia progression.
