Convergence insufficiency (CI) affects about 5 out of every 100 people. CI is an eye-teaming problem in which the eyes have a strong tendency to drift outward when reading or doing work up close. If the eyes drift out, the person may see double. To avoid seeing double, a person with CI must use extra effort to make the eyes turn back in. This extra effort can lead to annoying symptoms that can interfere with the ability to read and work comfortably up close.
Symptoms often associated with CI:
The CITT-ART was designed to find out whether therapy for CI improves reading and attention. Children with CI have many more symptoms when reading and show worse attention than children without CI. We know that CI therapy improves these symptoms and we have some early evidence that treatment also results in improvements in reading and attention.
However, to know for sure, we need to study this question in a larger group of children, and some children need to receive a harmless control therapy that is not designed to treat convergence insufficiency.
If you agree to have your child take part in the study, a computer program will determine whether your child will receive active or control therapy. This is similar to flipping a coin. Two of every three children will receive the active therapy. Children who receive the control therapy and don’t get better will be given the active treatment.
The study involves standard tests and treatments which have the same risks as receiving treatment outside the study. No long-term problems are expected. The only known risk is that your child may continue to have eyestrain/headaches.
To allow your child to take part in the study, you must be willing to bring your child to The Ohio State University’s College of Optometry for the following tests and sessions:
You will also need to ensure that your child performs the prescribed home therapy.
