Dischromotopsia Dyschromatopsia, achromatopsia, color vision deficiency an individual with
achromatopsia cannot tell the difference between colors. Some people with
achromatopsia can only see shades of gray. A person with this condition usually
has poor distance vision, light sensitivity, and rapid eye movement.
Dyschromatopsia is the more common form of color blindness. Individuals with
this condition usually have excellent vision. The person usually cannot tell the
difference between shades of red and green. In rare cases, the person cannot
tell the difference between shades of blue and yellow. Most hypotheses of
acquired dyschromatopsia invoke the mechanism of selective damage to specific
components of the afferent visual system toexplain the predominance of redgreen
and blue-yellow hue- discrimination defects found in neural and retinal
disorders, respectively. However, this pattern of hue-discrimination disturbance
in ocular disease may vary. There are frequent exceptions which are
inadequately explained by existing hypotheses. In an effort to explain the
pattern and pathogenesis of acquired dyschromatopsias better, the authors
examined patients withnonproliferative diabetic retinopathy (dr) and late-stage
retrobulbar neuritis (rbn) using age-corrected farnsworth-munsell 100-hue
testing and threshold static perimetry. As expected, most dr eyes showed some
degree of relative blue-yellow dyschromatopsia (89%) with few showing a
greater weighting towards red- green dyschromatopsia (11%). However,
an approximately equal number of rbn eyes had a relative blue-yellow
(48%)versus red-green dyschromatopsia (52%). For rbn, the authors found a
strong association between the spatial distribution of field defect and the type of
relative hue-discrimination disturbance. Eyes with greater field depression at the
fovea relative to the per fovea showed a relative preponderance of red-green
dyschromatopsia (68%) as opposed to blue- yellow dyschromatopsia (32%),
whereas eyes with greater relative perifoveal impairment showed a relative
preponderance of blue-yellow dyschromatopsia (100%). This relationship
between the relative spatial distribution of visual field damage and the relative
hue-discrimination deficit in rbn was statistically significant (p = 0.002). Such an
association was not found for dr.(abstract truncated at 250 words)
