Difficulty with Depth Perception While most visual disturbances after a stroke occur when the visual cortex has been damaged, a temporal lobe stroke may also cause problems with perception. Some temporal stroke survivors experience difficulties with depth perception or experience field cuts.What field defect results when a stroke only affects the occipital?
13. What field defect results when a stroke only affects the anterior portion of the occipital lobe? Retrochiasmal lesions normally cause homonymous visual field defects; the only exception is the ‘temporal crescent’ or ‘half moon syndrome’, caused by a lesion in the anterior part of the contralateral parieto-occipital sulcus.What is the pathophysiology of temporal lobe lesions?
Temporal lobe lesions, including those causing visual field defects, are often associated with personality changes, memory disturbances, complex auditory and visual disturbances, and complex partial seizures. A receptive aphasia may result from involvement of Wernicke's area.What is the prevalence of visual field loss after stroke?
Visual field loss is reported in the acute period following stroke in 45–67% of patients [2, 30, 45, 46] and in the long term for 8–25% of patients following adjustment for recovery of visual field and morbidity [3, 47, 48].
