Grossly incongruous, incomplete (contralateral) Homonymous Hemianopia causing lesion is

(B) Lateral optic chiasma # Visual fields that accompany damage to the visual pathways.1. Optic nerve: unilateral amaurosis.2. Lateral optic chiasm: grossly incongruous, incomplete (contralateral) homonymous hemianopia.3. Central optic chiasm: bitemporal hemianopia.4. Optic tract: incongruous, incomplete homonymous hemianopia.5. Temporal (Meyer's) loop of the optic radiation: congruous partial or complete (contralateral) homonymous superior quadrantanopia.6 Parietal (superior) projection of the optic radiation: congruous partial or complete homonymous inferior quadrantanopia.7. Complete parieto-occipital interruption of the optic radiation: complete congruous homonymous hemianopia with psycho- physical shift of the foveal point, often sparing central vision and resulting in "macular sparing."8. Incomplete damage to the visual cortex: congruous homonymous scotomas, usually encroaching at least acutely on central vision.
