Abstract:
There is no standard meaning of the term "vision therapy", and for this reason it is often a controversial topic between some members of the ophthalmic and optometric community. Most pediatric ophthalmologists avoid using the term because it is nonspecific. Convergence Insufficiency (CI) is a binocular visual problem that causes problems and symptoms with near fixation. There is consensus among eye care professionals that convergence therapy is effective in treating CI. Convergence therapy is not effective in treating learning disabilities, but can sometimes relieve symptoms that might be a barrier to reading.
