Temporal Desaturation
Temporal Desaturation
Temporal desaturation refers to an impairment in perception of red targets confined to the temporal visual hemifield. This may be the earliest indication of a developing temporal field defect, as in a bitemporal hemianopia due to a chiasmal lesion, or a monocular temporal field defect (junctional scotoma of Traquair) due to a distal ipsilateral optic nerve lesion.
