Objective: In Quebec a driver whose acquired visual field defect renders them ineligible for a driver's permit renewal may request an exemption from the visual field standard by demonstrating safe driving despite the defect. For safety reasons it was decided to attempt to identify predictors of ...
Epilepsy surgery, visual fields, and driving: a study of the visual field criteria for driving in patients after temporal lobe epilepsy surgery with a comp... Twenty four patients who had undergone temporal lobe surgery for epilepsy were assessed to determine (a) whether or not they had ...
A developing visual field defect 喜欢 0 阅读量: 33 作者: AJ Larner 摘要: A 53 year old man complained of intermittent blurring of vision confined to the left eye over a period of 12 months. It did not stop him from reading or driving. There was no history of visual loss, eye pain,...
which are called scotomas. The size and shape of the scotoma indicates what the cause might be. For instance, if there is damage to the optic nerve, a person will experience a specific visual field defect unlike any other. In addition, doctors ...
The visual field test requires that a driver in the UK have a minimum horizontal field of vision of 120 degrees and no significant defect of more than 20 degrees of fixation. If your vision deviates from this requirement, then you can have your license revoked. You should go to yo...
In another process, the area of a visual field defect is calculated using the visual field representation. In another process, the visual field representation is used to generate a statistical description of the volume of a patient's visual field defect. 展开 ...
This reduced to 46±9 and 46±11 when completing the task with a binocular visual field defect located to the left and right of fixation, respectively. While the main effect of simulated visual field loss on performance was statistically significant (p=0.007), there were no average differences...
Homonymous hemianopia (HH) is a visual field defect that is defined by complete or partial blindness in the visual fields to the right or left side of both eyes, commonly caused by cerebral infarction [1]. Visual field defects are estimated to affect 20 to 57% of people who have had ...
The pattern of defect is typically a bilateral, absolute concentric constriction of the visual field, the severity of which varies from mild to severe. Data gathered so far suggest that the cumulative incidence increases rapidly during the first 2 years of treatment and within the first 2kg of ...
