What would be the lesion in the optic pathway in the ff visual field defect:
- Optic nerve
- Optic chiasm
- Optic tract
- Inferior optic radiation (temporal pathway or Meyer loop)
- Superior optic radiation (parietal pathway)
- Optic nerve - monocular vision loss
- Optic chiasm - bitempotal hemianopsia
- Optic tract - contralateral homonymous hemianopsia
- Inferior optic radiation (temporal pathway or Meyer loop) - contralateral superior quadrantanopsia
- Superior optic radiation (parietal pathway) - contralateral inferior quadrantanopsia
