Convergence insufficiency is a condition that affects 7% of the population.
Patients with convergence insufficiency can have poor voluntary abilities to point their eyes inward when looking at objects or print at near. Patients with recent onset convergence insufficiency are often symptomatic with complaints of blurred vision, double vision, eyestrain, or headaches.
In its early stages, convergence insufficiency is the most treatable binocular dysfunction. Studies have shown a 70-95% success rate in treating convergence insufficiency.
Amanda's mother sent our office the following report:
"During a routine eye exam. Dr. Kageyama diagnosed Amanda with "convergence insufficiency." He recommended that we should do therapy no later than 3rd grade.
Amanda is a good student but her homework became a struggle in 2nd grade. Her frustration levels (usually manifest at home) were very high. She was angry with her parents and would not cooperate with the daily routine.
Recently, after therapy, she tested at the 10th grade level in reading. Her homework is coming along better – In the last three weeks both my husband and I have noticed her attitude has improved. She now tells us that she loves us and hugs us spontaneously . She seems happier. I am very pleased with my daughter’s progress. THANK YOU!"
