The symptoms include loss of visual acuity, metamorphopsia, micropsia, dyschromatopsia, scotoma, and reduced contrast sensitivity. |
|
Despite obvious cortical atrophy in VVAD, dyschromatopsia is not typically found in these patients. |
|
The abnormal results on Ishihara pseudoisochromatic plates test are then related to simultanagnosia instead of a true dyschromatopsia. |
|
Using a finger to trace the path on Ishihara color plates could help separating simultanagnosia from dyschromatopsia in VVAD patients. |
|
Neuro-opthalmic signs include afferent pupillary defect, dyschromatopsia, and in some cases changes in visual acuity. |
