Home therapy for vision problem might not be sufficient

Convergence insufficiency, or CI, is a muscle coordination problem that affects one 1 of every 20 children. It can cause problems with reading and writing.

Many diagnosed with CI do eye exercises at home to strengthen muscles so the eyes do a better job of focusing. But the NIH report finds children make even more progress when the home exercises are combined with therapy done by an eye care professional.

According to the study, 75 percent of those who had the combined therapy had fewer and less severe symptoms after 12 weeks.
