NCT ID: NCT02667509 Completed - Refractive Error Clinical Trials

The Evolutionary Model of Mild-to-moderate Myopia in China

Start date: January 2005
Phase: N/A
Study type: Observational

Myopia has emerged as a major health issue in east Asia, because of its increasingly high prevalence in the past few decades (now 80-90% in school-leavers), and because of the sight-threatening pathologies associated with high myopia, which now aff ects 10-20% of those completing secondary schooling in this part of the world. Similar, but less marked, changes are occurring in other parts of the world. The higher prevalence of myopia in east Asian cities seems to be associated with increasing educational pressures, combined with life-style changes, which have reduced the time children spend outside.

NCT ID: NCT02607384 Completed - Refractive Error Clinical Trials

The Baltimore Reading and Eye Disease Study

BREDS
Start date: November 2014
Phase: N/A
Study type: Interventional

The Baltimore Reading and Eye Disease Study (BREDS) is a two year study to determine the prevalence of vision problems in an early school age population with reading difficulty. Comprehensive vision and reading tests will be administered to 400 students at participating schools in the Baltimore City Public School system. A secondary goal is to examine the impact of vision treatment on reading performance. Children with refractive error or convergence insufficiency will be provided treatment free of charge. The investigators will evaluate the impact that the treatment has on vision function and reading performance.
