Preventing visual field deficits from neurosurgery
OBJECTIVE We assessed whether display of optic radiation tractography during anterior temporal lobe resection (ATLR) for refractory temporal lobe epilepsy (TLE) can reduce the severity of postoperative visual field deficits (VFD) and increase the proportion of patients who can drive and whether correction for brain shift using intraoperative MRI (iMRI) is beneficial. METHODS A cohort of 21 pa...
متن کاملPreoperative visual field deficits in temporal lobe epilepsy☆
Surgical resection and laser thermoablation have been used to treat medically refractory epilepsy with good results. However, they are not without risk. One of the most commonly reported complications of temporal lobe surgery is contralateral superior homonymous quadrantanopsia. We describe a patient with quadrantanopsia discovered as part of our recently modified protocol to workup patients pr...
متن کامل“Sightblind”: Perceptual Deficits in the “Intact” Visual Field
Unilateral visual cortex lesions caused by stroke or trauma lead to blindness in contralateral visual field - a condition called homonymous hemianopia. Although the visual field area processed by the uninjured hemisphere is thought to be "intact," it also exhibits marked perceptual deficits in contrast sensitivity, processing speed, and contour integration. Such patients are "sightblind" - thei...
متن کاملDo visual field deficits exacerbate visuo-spatial neglect?
A significant association between visual field deficits (VFD) and visuo-spatial neglect is well established, although cases of double-dissociation between the two conditions are not uncommon. It has been argued that VFD typically exacerbates the behavioural manifestations of neglect. We examined a series of 51 patients with unilateral right-hemisphere stroke for the presence of visual field def...
متن کاملPredicting binocular visual field sensitivity from monocular visual field results.
PURPOSE To compare methods of predicting binocular visual field sensitivity of patients with glaucoma from monocular visual field data. METHODS Monocular and binocular visual fields were obtained for 111 patients with varying degrees of glaucomatous damage in one or both eyes, using the Humphrey 30-2 full-threshold procedure. Four binocular sensitivity prediction models were evaluated: BEST E...
