Macular sparing is seen in a lesion of
Retention of macular function in spite of losses in the adjacent visual field. Example: In homonymous hemianopia due to an occipital lobe lesion (e.g. an interference in the blood flow in the middle cerebral aery). Reason: Macula has a dual blood supply of both MCA and PCA Visual Field Defects - Left Hemianopia with Macular Sparing. Left hemianopia with macular sparing is a paial loss of vision in the same half of both eyes with the center, the macula, spared. A lesion of both the dorsal radiation and Meyer&;s loop in the occipital lobe causes this blindness Reference: khurana 6th edition pg 677
