QuestionSBA
QuestionChoice
Incorrect - Lesions affecting the occipital lobe can result in a macular sparing homonymous hemianopia.  The visual field on the contralateral side is affected. As this patient has a lesion in their right occipital cortex, we would expect a macular-sparing left homonymous hemianopia, rather than a right.
