Saccadic 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...

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...

The Effects of Short-Lasting Anti-Saccade Training in Homonymous Hemianopia with and without Saccadic Adaptation

Homonymous Visual Field Defects (HVFD) are common following stroke and can be highly debilitating for visual perception and higher level cognitive functions such as exploring visual scene or reading a text. Rehabilitation using oculomotor compensatory methods with automatic training over a short duration (~15 days) have been shown as efficient as longer voluntary training methods (>1 month). He...

Can 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...

Field Expansion for Homonymous Hemianopia

Visual field loss following a cortical lesion from stroke, brain surgery, or head trauma frequently manifests as homonymous hemianopia. Hemianopic field loss causes problems in mobility and navigation as well as reading. Patients frequently complain of bumping into obstacles on the side of the field loss and getting bruised on their arms and legs. The number of such accidents decreases with ada...
