Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

An upper homonymous quadrantanopia describes the loss of the same upper quadrant from each visual field.

Upper homonymous quadrantanopias are usually caused by damage to the optic radiation as it passes throught the temporal lobes.

For example a lesion in the left temporal lobe will cause a right homonymous upper quadrantanopia, that is the loss of the upper nasal quadrant from the left eye and the upper temporal quadrant from the right eye.
