When the pathology involves both eyes, it is either homonymous or heteronymous. Homonymous<unk>  Paris as seen with left homonymous<unk> . A homonymous<unk>  is the loss of half of the visual field on the same side in both eyes. The visual images that we see to the right side travel from both eyes to the left side of the brain, while the visual images we see to the left side in each eye travel to the right side of the brain. Therefore, damage to the right side of the posterior portion of the brain or right optic tract can cause a loss of the left field of view in both eyes. Likewise, damage to the left posterior brain or left optic radiation can cause a loss of the right field of vision.Paris as seen with binasal<unk> . Heteronymous<unk>  Paris as seen with bitemporal<unk> . A heteronymous<unk>  is the loss of half of the visual field on different sides in both eyes. It is separated into two categories: * Binasal<unk>  – the loss of the fields surrounding the nose; * Bitemporal<unk>  – the loss of the fields closest to the temples. Other forms *Superior<unk>  – the upper half of the field of vision is affected, possibly because of a tumor beginning to compress the lower part of the chiasma, typically one from the hypophysis. *Inferior<unk>  – the lower half of the field of vision is affected, possibly because of a tumor beginning to compress the upper part of the chiasma, typically a craniopharyngioma. Quadrantanopia Superior right quadrantanopia. Quadrantanopia (quadrantanopsia or quadrantic<unk>  is decreased vision or blindness in one quarter of the visual field. The particular quarter of vision missing depends on whether the location of the brain damage is temporal or parietal, and the side of the lesion. For example, a lesion to the right temporal lobe with damage specifically to Meyer's loop will give rise to a left upper (superior) quadrantanopsia, while a lesion to the right parietal radiation with damage specifically to Baum's loop will result in a left lower (inferior) quadrantanopsia.
