3. The ColorDx Computerized Color Vision Test Windows Application (CCVT) was the primary color vision test used to detect and classify the different color vision deficiencies in the following cases.
Consequently, I am including a brief overview of this particular computerized color vision test for those attendees not familiar with it.

4. The CCVT includes one demo & 25 pseudoisochromatic test plates in the General Section. The other three sections use desaturated test plates that progress from high visibility to low visibility as the hue becomes less saturated and contrast is decreased.
Total 102

5. Example of an individual number using a protan confusion color.

6. It becomes less saturated, less visible.

7. Continues to be even less saturated/visible until it can no longer be seen by color deficient subjects.

8. It automatically scores itself and gives color normals a certificate

9. Color deficient subjects get a diagnosis plus a score of how they did on each section. The score can be printed or saved on your computer or network.

10. Characteristics of congenital versus acquired color vision deficiencies
On set after birth color;
vision previously normal
Present at birth
Type and severity remains the same
Type and severity can change with time
*Predominantly starts as a tritan
Monocular differences in severity
Frequently occur.
Both eyes equally affected
Reduces visual acuity and/or
visual field defects
Visual acuity and visual
field normal
Normally a Healthy individual
Possible associated disease process

11. CASE #1
Right Eye

12. Left Eye

13. Additional Color Vision Test Results
1. Ishihara
Rt Eye: Normal Color Vision
Lt Eye: Abnormal Color Vision, 2/14 correct
2. Nagel Anomaloscope

46. Case # 5 Should we be routinely testing color vision?

49. “We should all be routinely screening for color vision deficiencies.”
Yes!
“We should all be routinely screening
for color vision deficiencies.”
Detecting a color vision deficiency can raise a red flag and help diagnose a disease process.

50. I would like to thank my
colleagues at the Naval Aerospace Medical Institute for their help preparing my presentation:
