homonymous hemianopia Scanning the visual world : a study of patients
Objectives—This study examined the scanpaths of patients with homonymous hemianopia while viewing naturalistic pictures in their original and also spatially filtered forms. Features of their scanpaths with respect to various saccade and fixation parameters were examined to determine whether they develop compensatory eye movement strategies. The eVects of various lesion parameters including loca...

متن کاملCan visual function be restored in patients with homonymous hemianopia?
It can be argued that vision is the major sensory input into the human brain, by virtue of the fact that about half of all aVerent fibres projecting to the brain are from the eye and by the sophistication of the neural systems controlling visual processing. Brain damage disrupts these complicated processes, resulting in severe visual impairments including hemianopia. Patients with hemianopia co...
متن کاملSaccadic visual search training: a treatment for patients with homonymous hemianopia.
OBJECTIVES We describe a novel rehabilitation tool for patients with homonymous hemianopia based on a visual search (VS) paradigm that is portable, inexpensive, and easy to deploy. We hypothesised that by training patients to improve the efficiency of eye movements made in their blind field their disability would be alleviated. METHODS Twenty nine patients with homonymous visual field defects...
