Dr. William E. Leadingham, O.D., FCOVD Developmental Optometrist Ashland, Kentucky Article 1 I have been using your instrument for several years on all of my patients that I recommend visual rehabilitation for. In my office, all patients that I see have an initial comprehensive eye health and visual examination. If after this evaluation it is determined that a patient has a binocular visual dysfunction then they are rescheduled for an in depth Developmental Visual Evaluation to determine the cause and degree of their particular binocular visual problem. The Developmental Visual Evaluation consists of a battery of several standardized tests to analyze the exact cause and degree of the binocular visual problem(s). I have found that there is a high correlation between five of the standardized tests from my test battery and your Computerized Functional Colour Field Test. As you know, under stress, the human body response is to draw in or constrict. This predicable response can clearly be seen in a patient's subjective response on these five tests and Colour Field Testing. I have enclosed two patient case studies to show you how these five tests and your Colour Field test results can be used to predict possible treatment outcome. I also use these pre and post therapy changes to demonstrate to the patient their improvement.

The Colour Field test showed a mean average increase in the right colour field of +3.4' and the left field of +4.7'. The Keystone Visual Skills Profile showed a post treatment condition of more stable and flexible binocular visual posture. The Van Orden Binocular Space test showed a more post stable and exacting eye hand placement. The VEP showed a post faster Latency (impulse speed) and a stronger Amplitude (Impulse Strength). The TVPS showed an 85% rank improvement with a +5 years 6 months visual perceptual age gain.

The Colour Field test showed a marked increase in both the right and left colour fields. The Keystone Visual Skills Profile showed a post treatment condition of more stable and flexible binocular visual posture. The Van Orden Binocular Space test showed a more post stable and exacting eye hand placement. The VEP showed a post faster Latency (impulse speed) and a stronger Amplitude (Impulse Strength). The TVPS showed a 44% rank improvement with a +4 years 9 months visual perceptual age gain. Read the whole article
