Massachusetts Eye and Ear Infirmary A diagnosis of hemianopia, or blindness in one half of the visual field in both eyes as the result of strokes, tumors or trauma often means the end of driving. In about half of the states in the United States and in many other countries, driving with hemianopia is prohibited. However, in some countries including Belgium, the Netherlands, the UK, Switzerland and Canada, driving with hemianopia is permitted after passing a specialized road test....

Thousands of people who are partially-sighted following stroke or brain injury could gain greater independence from a simple, cheap and accessible training course which could eventually be delivered from their mobile phones or hand-held games consoles, according to a new study. The new research has found that a computer-based technique developed and assessed by Durham University improved partially-sighted people's ability to 'see' better. It may eventually improve and broaden the portfolio of...

Schepens Eye Research Institute scientists have found that--when tested in a driving simulator--patients with hemianopia (blindness in one half of the visual field in both eyes) have significantly more difficulty detecting pedestrians (on their blind side) than normally sighted people. These results, published in the November 2009 issue of Investigative Ophthalmology and Visual Science, fly in the face of some recent on-road studies that have found most people with hemianopia safe to drive....

BOSTON, Aug. 31 /PRNewswire/ -- A high-tech device that expands the visual field of patients with tunnel vision has passed a collision test in a walking simulator, according to scientists at Schepens Eye Research Institute, in a study published in the September issue of Investigative Ophthalmology and Visual Science. The study found that patients wearing this innovative device, consisting of a tiny camera, pocket-sized computer and a transparent computer display on a pair of glasses, were...

Suggests additional training to help brain adapt more fully and further enhance benefits BOSTON, May 19 /PRNewswire-USNewswire/ -- In a study of specially designed peripheral prism glasses for hemianopia patients (blinded in half the visual field in both eyes), scientists found that two-thirds of patients continued to wear the glasses at the end of the study period and beyond, indicating a high level of success. They also found that the brains of patients had not fully remapped to adjust...

By Karla Gale NEW YORK (Reuters Health) - A new approach that permits wider visual perception in patients with severely restricted peripheral field allows quicker and more accurate ability to detect objects outside their field of vision, suggest results of a pilot study. People who suffer from tunnel vision can only see what is directly ahead of them. The condition, which is caused by such diseases as glaucoma, impairs a person's ability to perform daily activities. Reversed...
