 Patching and atropine have been traditionally used for the improvement of visual acuity in children with amblyopia. Previous studies have shown that these methods of treatment are effective in young children with functional amblyopia. More recently ATS3, a randomized clinical trial of 507 children ages 7-18, found that part-time patching combined with atropine and near activities improved visual acuity by two or more lines in 53 of the 7 to 12 year olds compared to 25 for optical correction alone. For the 13 to 17 year olds, part-time patching and near activities improved visual acuity by 2 or more lines in 25, compared to 23 for optical correction alone. While it appears that patching andor atropine, combined with near activities, can improve visual acuity in some patients ages 7-18, most patients in the study were left with residual visual acuity deficits. To further improve visual acuity and binocularity in children with amblyopia some eye care providers augment these traditional therapies with vision therapy. Vision therapy is prescribed initially if there is moderate amblyopia with stereopsis. Vision therapy can be added to the treatment regimen once the patient has reached moderate levels of vision loss with stereopsis and if the patient is still not responding to the current treatment and still has moderate amblyopia. It is thought that the best candidates for this type of therapy are those children with a minimum level of stereopsis at least 800 and without constant strabismus. Those children with no stereopsis would not be able to perform the activities in the later stages of therapy utilizing binocular vision.
