Binocular coordination, speed of accommodation and other important functions are not measured at all. Acuity is only one of many elements of good vision. The inability to create easy, rapid and clear binocular vision can dramatically interfere with reading, attention and comprehension. In adult life many people suffer needless headaches and confusion stemming from poor visual processing. Sixty to eighty percent of children with reading disabilities have measurable, correctable problems in accurate aiming of both eyes at the line of print.
Many children have limited depth perception due to failures of proper binocular vision.
These deficits lead to poor eye-hand coordination, clumsiness, and performance problems. Vision therapy corrects these problems through a training process in which the patient learns to control the convergence and divergence of the eyes. We use both stationary and moving 3-D visual targets to develop these skills. A computer program also is used to improve visual processing accuracy and speed. For example, patients with difficulties confusing similar letters like b and d can be trained to make more rapid and accurate discrimination between these confusing letters.
