Convergence Insufficiency and Double Vision
Convergence Insufficiency and Double vision
Many vision disorders are not detectable without a comprehensive eye examination. The way our eyes team together and focus directly affects our ability to read, process and understand visual information. When our two eyes don’t work together properly to make a single image, it can lead to double vision, headaches, poor depth perception and significant impacts on our ability to read.
The most common eye teaming problem is Convergence Insufficiency or CI. The CITT, or Convergence Insufficiency Treatment Trial, is a multi-center study funded by the National Institutes of Health. The members of the CITT found that Convergence Insufficiency occurs in approximately 10-15% of the regular population! It often is associated with symptoms such as double vision, eyestrain, headaches, blurred vision, and loss of place while reading or performing near work. Some patients simply avoid reading or act as if they have ADD or ADHD. A child may not report the previously stated symptoms because they refuse to read long enough for them to occur.
Convergence Insufficiency may occur in children and adults. Once treated, reading, attention and other school performance problems dramatically improve.
