Abstract

The purpose of this paper is to show a new cause of a macular scotoma and an anomalous acquired color-vision deficiency in the clinical fovea caused by retina detachments and subsequent surgeries. This deficiency was measured with a visual test system composed of multiple lasers, a white light beam and dozens of targets that were projected on a computer monitor and printed on paper. Lasers were used, because they produce small monochromatic target dots, 0.07 degrees of visual angle (6 mm) in diameter. The outputs of the system were the subject’s perceived color matches. In experiments with small dots of laser light, colors were judged correctly by the right eye (OD): however, the left eye (OS) could not distinguish colors. For example, a green laser dot appeared green to his OD and white to his OS. Perceived color in the abnormal OS depended on the target’s hue, saturation, luminance, wavelength, size and position on the fovea. This subject has an acquired color-vision deficiency in the clinical fovea of his OS. These visual anomalies are consistent with damage to retinal ganglion cells. Strangely, his OS does not see negative-color afterimages.
