The phenomenon of macular avoidance is defined as the preservation of the function of the central gaze area during visual field examination in both partial and total blindness visual fields. The phenomenon is seen in damage or lesions in the middle and posterior part of the optic radiation or in the visual cortex area. Differential diagnosis of macular avoidance phenomenon: 1. Occipital lobe damage due to occipital lobe tumor, occipital lobe cerebral infarction and other diseases affecting a symptom. The patient’s occipital lobe is damaged. The main manifestation is visual impairment. When unilateral occipital lobe lesions, the center of the visual field often stays, that is, the so-called macular avoidance phenomenon. 2, posterior cerebral artery obstruction manifests as ipsilateral hemianopsia on the opposite side of the lesion, with macular avoidance and cortical blindness or quadrant blindness. 3, central hemianopsia light reflex exists, quadrant hemianopsia, mostly without conscious symptoms, the latter visual field center visual acuity is preserved in, macular avoidance phenomenon. Usually pay attention to protect their head, try to avoid head injury, strengthen exercise, prevent various neurological diseases.
